The popular iconography of insight casts a thinker as he or she uncoils from a Rodin pose and a bulb that lights a world hitherto hidden. By and large, these features of folk mythology capture and guide how psychologists conduct research on insight: Mental processes — some of which may be unconscious — transform an inceptive abstract representation of the world until it prescribes a fruitful solution to a problem. Yet thinking and problem solving outside the laboratory involve (...) interacting with external resources, and through this interactivity with a material world, solutions are distilled. Still, laboratory work on problem solving pays scant and largely indifferent attention to interactivity: Sometimes problems are presented as riddles or static graphical or diagrammatic images, or sometimes they are accompanied by artefacts that can be manipulated. The research methodology — and indifference to the central role of interactivity in thinking — follows from a deep-seated commitment to mentalism and methodological individualism. However, a thinker is an embodied creature embedded in a physical world: The materiality of external resources and artefacts through which problems manifest themselves inevitably determines a set of action affordances. From a systemic perspective, thinking is traceable along a contingent spatio-temporal itinerary wrought by interactivity and evidenced by changes in the world. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Movements of the Mind. A Theory of Attention, Intention and Action by Wayne WuDiego D’AngeloWU, Wayne. Movements of the Mind. A Theory of Attention, Intention and Action. Oxford: Oxford University Press, 2023. 257 pp. Cloth, $80.00Wayne Wu presented a theory of attention as selection-for-action in 2014. According to this theory, given a behavioral space in which the agent has multiple inputs and outputs to choose (...) from, attention involves the selection of a particular course of action, that is, of certain outputs based on certain inputs. In the present work Wu puts to use the selection-for-action theory to shed light on the broader topic of the “movements of the mind”: intentionality and action. Action and movement are mostly not intended as bodily movement: By focusing on mental actions Wu aims to simplify philosophical explanations. His overall theoretical approach remains consistent with his work on attention, which involves a quest to develop rigorous philosophical concepts while incorporating insights from the empirical sciences. Interestingly, biology takes precedence over cognitive sciences and psychology for him; he says, “I aspire to a biology of agency” in which philosophical analysis must respond to “empirical friction.” In this framework, this book puts forth four main claims. The first concerns the general structure of action—action arises from solving a selection problem. Second, intentional actions can be differentiated from unintentional actions using the concepts of automaticity and control. Third, Wu argues that attention is a necessary aspect of every theory of action. Fourth, he claims that intention is practical memory for action. These four are woven throughout the different chapters of his book.The first part analyzes the structure of action along three axes: how the agent “takes things to be” as the basis for selection, the agent’s response to those things, and the biases that explain the link between perceptions and responses. In the second part, Wu presents a theory of intention as practical memory. The theory is surprising, as Wu himself acknowledges when he says, “The approach to intention will, I think, jar many readers.” And indeed, it does, but Wu provides strong arguments, and future work will determine if the theory is feasible. The third part of the book explores the implications of his theory of action for specific forms and aspects of action; the first chapter in this section deals with automaticity and biases, [End Page 734] the second deals with deductive reasoning, and the third deals with introspection.According to Wu’s theory, action involves a complex combination of elements. The agent is faced with many inputs and potential outputs within a behavioral space. She takes inputs in a certain way: The way she sees things is influenced by myriad aspects, such as intentions and biases of various forms. Action and intending to act are solutions to the problem of selecting appropriate inputs and outputs. Wu thematizes the role of attention in this process of selection. Attention comes in three different forms. It can be an action itself (“attending,” for example, in searching for something); it can mean “vigilance” as readiness to act; and most importantly, attention is “mental guidance.” Every action is guided by attention insofar as a selection problem must be solved: Attention is guiding when perceptual input “plays a functional role of guiding.” Attention also shapes the agent’s actions through remembering, and remembering in turn is nothing else then attending to remembered content. This attended content provides the agent with biases and reasons to select a particular course of action. Therefore, intending to act is nothing else than practical memory, that is, memory put to work in the choice of actions.One particular type of action that is crucially important for philosophical research is introspection. According to Wu, introspection, like every kind of mental action, is not entirely reliable—as some theories would have it—or entirely unreliable but, instead, depends on context. Like any other action, introspection follows the same guiding principle, attention, specifically, perceptual attention. Therefore, introspection is a particular type of perceptual experience where attention is focused on one’s own mental states. In this way, Wu establishes criteria for veridical introspective reports, such... (shrink)

According to the restructuring hypothesis, insight problem solving typically progresses through consecutive stages of search, impasse, insight, and search again for someone, who solves the task. The order of these stages was determined through self-reports of problem solvers and has never been verified behaviorally. We asked whether individual analysis of problem solving attempts of participants revealed the same order of problem solving stages as defined by the theory and whether their subjective feelings corresponded to the problem (...) solving stages they were in. Our participants tried to solve the Five-Square problem in an online task, while we recorded the time and trajectory of their stick movements. After the task they were asked about their feelings related to insight and some of them also had the possibility of reporting impasse while working on the task. We found that the majority of participants did not follow the classic four-stage model of insight, but had more complex sequences of problem solving stages, with search and impasse recurring several times. This means that the classic four-stage model is not sufficient to describe variability on the individual level. We revised the classic model and we provide a new model that can generate all sequences found. Solvers reported insight more often than non-solvers and non-solvers reported impasse more often than solvers, as expected; but participants did not report impasse more often during behaviorally defined impasse stages than during other stages. This shows that impasse reports might be unreliable indicators of impasse. Our study highlights the importance of individual analysis of problem solving behavior to verify insight theory. (shrink)

Despite an abundance of academic conferences, clinical ethicists lacked a forum to share innovative practices with peers and to generate solutions to common challenges. Organizers of the first Clinical Ethics Un-Conference developed a working event centered on active participation and problem solving through peer learning, with the goal of improving realworld practice. Registrants included 95 individuals from 64 institutions. Attendees were surveyed immediately after the Un-Conference, and again eight months later. After eight months, 85 percent (n = 33/39) of (...) the survey respondents reported that they found the event “highly impactful” or “some-what impactful” to their clinical practice, and 23 attendees reported that they had implemented ideas or projects inspired by the event. Three sets of best practice guidelines and four white papers were published from the event. As the field of clinical ethics continues to advance and evolve, this working event format offers an innovative, disruptive alternative to a traditional conference format and may serve as a model for future efforts aimed at improving real-world clinical ethics practice.

Dolphins exhibit both action-level imitation (ALI) and program-level imitation (PLI). Dolphins may use ALI primarily for social cohesion, whereas PLI seems more likely to occur in goal-directed, problem-solving contexts. Both PLI and insightful problem solving require a recognition of the functional relations between actions and outcomes. Insightful problem solving, however, involves the creation of a program in the absence of a model, and therefore requires a higher order appreciation and application of the relations between actions and outcomes.

Parkinson's disease patients receiving dopaminergic treatment may experience bursts of creativity. Although this phenomenon is sometimes recognized among patients and their clinicians, the association between dopamine replacement therapy in PD patients and creativity remains underexplored. It is unclear, for instance, whether DRT affects creativity through convergent or divergent thinking, idea generation, or a general lack of inhibition. It is also unclear whether DRT only augments pre-existing creative attributes or generates creativity de novo. Here, we tested a group of PD (...) patients when “on” and “off” dopaminergic treatment on a series of tests of creative problem-solving, and related their performance to a group of matched healthy controls as well as to their pre-PD creative skills and measures of inhibition/impulsivity. Results did not provide strong evidence that DRT improved creative thinking in PD patients. Rather, PD patients “on” medication showed less flexibility in divergent thinking, generated fewer ideas via insight, and showed worse performance in convergent thinking overall than healthy controls. Pre-PD creative skills predicted enhanced flexibility and fluency in divergent thinking when PD patients were “on” medication. However, results on convergent thinking were mixed. Finally, PD patients who exhibited deficits in a measure of inhibitory control showed weaker convergent thinking while “on” medication, supporting previous evidence on the importance of inhibitory control in creative problem-solving. Altogether, results do not support the hypothesis that DRT promotes creative thinking in PD. We speculate that bursts of artistic production in PD are perhaps conflated with creativity due to lay conceptions of creativity. (shrink)

In the last 20 years, a stream of research emerged under the label of „complex problem solving“ (CPS). This research was intended to describe the way people deal with complex, dynamic, and intransparent situations. Complex computer-simulated scenarios were as stimulus material in psychological experiments. This line of research lead to subtle insights into the way how people deal with complexity and uncertainty. Besides these knowledge-rich, realistic, intransparent, complex, dynamic scenarios with many variables, a second line of research used more simple, (...) knowledge-lean scenarios with a low number of variables („minimal complex systems“, MCS) that have been proposed recently in problem-solving research for the purpose of educational assessment. In both cases, the idea behind the use of microworlds is to increase validity of problem solving tasks by presenting interactive environments that can be explored and controlled by participants while pursuing certain action goals. The main argument presented here is: both types of systems - CPS and MCS – can only be dealt with successfully if causal dependencies between input and output variables are identified and used for system control. System knowledge is necessary for control and intervention. But CPS and MCS differ in their way of how causal dependencies are identified and how the mental model is constructed; therefore, they cannot be compared directly to each other with respect to the cognitive processes that are necessary for solving the tasks. Knowledge-poor MCS tasks address only a small fraction of the cognitive processes and structures needed for knowledge-rich CPS situations. (shrink)

What cognitive abilities underpin the use of tools, and how are tools and their properties represented or understood by tool-users? Does the study of tool use provide us with a unique or distinctive source of information about the causal cognition of tool-users? -/- Tool use is a topic of major interest to all those interested in animal cognition, because it implies that the animal has knowledge of the relationship between objects and their effects. There are countless examples of animals developing (...) tools to achieve some goal-chimps sharpening sticks to use as spears, bonobos using sticks to fish for termites, and New Caledonian crows developing complex tools to extracts insects from logs. Studies of tool use have been used to examine an exceptionally wide range of aspects of cognition, such as planning, problem-solving and insight, naive physics, social relationship between action and perception. A key debate in recent research on animal cognition concerns the level of cognitive sophistication that is implied by animal tool use, and developmental psychologists have been addressing related questions regarding the processes through which children acquire the ability to use tools. In neuropsychology, patterns of impairments in tool use due to brain damage, and studies of neural changes associated with tool use, have also led to debates about the different types of cognitive abilities that might underpin tool use, and about how tool use may change the way space or the body is represented. -/- Tool Use and Causal Cognition provides a new interdisciplinary perspective on these issues with contributions from leading psychologists studying tool use and philosophers providing new analyses of the nature of causal understanding A ground-breaking volume which covers several disciplines, this volume will be of interest to psychologists, including animal researchers and developmental psychologists as well as philosophers, and neuroscientists.

_ Source: _Volume 94, Issue 3, pp 391 - 409 The author outlines a provisional phenomenology of problem solving. He begins by reviewing the history of problem-solving psychology, focusing on the Gestalt approach, which emphasizes the influence of prior knowledge and the occurrence of sudden insights. He then describes problem solving as a process unfolding in a field of consciousness against a background of unconscious knowledge, which encodes action patterns, schemata, and affordances. A global feeling of wrongness or tension (...) is resolved by a series of field transitions, which are guided by peripheral experiences of coherence or “rightness.” The author treats the distinction between reproductive thought and productive thought as a difference in field structure. With reproductive thoughts and actions we perform operations to solve a problem in a semi-automatic sequence. In productive thought, by contrast, a kind of parallel search occurs. This may explain the otherwise obscure phenomenology of struggling to break an impasse. (shrink)

Who Moved My Cheese? showed readers how to adapt to change. Fish! helped raise flagging morale. Execution guided readers to overcome the inability to get things done. QBQ! The Question Behind the Question , already a phenomenon in its self-published edition, addresses the most important issue in business and society today: personal accountability. The lack of personal accountability has resulted in an epidemic of blame, complaining, and procrastination. No organization-or individual-can achieve goals, compete in the marketplace, fulfill a vision, or (...) develop people and teams without personal accountability. The solution involves an entirely new approach. We can no longer ask, "Who dropped the ball?" "Why can't they do their work properly?" or "Why do we have to go through all these changes?" Instead, every individual has to ask the question behind the question: "How can I improve this situation?" "What can I contribute?" or "How can I make a difference?" Succinct, insightful, and practical, QBQ! The Question Behind the Question provides a method for putting personal accountability into daily action, which can bring astonishing results: problems get solved, barriers come down, service improves, teamwork grows, and people adapt to change.

In recent years there has been an upsurge of research aimed at removing the mystery from insight and creative problem solving. The present special issue reflects this expanding field. Overall the papers gathered here converge on a nuanced view of insight and creative thinking as arising from multiple processes that can yield surprising solutions through a mixture of “special” Type 1 processes and “routine” Type 2 processes.

The affirmative answer to the title question is justified in two ways: logical and empirical. The logical justification is due to Gödel’s discovery that in any axiomatic formalized theory, having at least the expressive power of PA, at any stage of development there must appear unsolvable problems. However, some of them become solvable in a further development of the theory in question, owing to subsequent investigations. These lead to new concepts, expressed with additional axioms or rules. Owing to the so-amplified (...) axiomatic basis, new routine procedures like algorithms, can be reached. Those, in turn, help to gain new insights which lead to still more powerful axioms, and consequently again to ampler algorithmic resources. Thus scientific progress proceeds to an ever higher scope of solvability. The existence of such feedback cycles –in a formal way rendered with Turing’s systems of logic based on ordinal – gets empirically supported by the history of mathematics and other exact sciences. An instructive instance of such a process is found in the history of the number zero. Without that insight due to some ancient Hindu mathematicians there could not arise such an axiomatic theory as PA. It defines the algorithms of arithmetical operations, which in turn help intuitions; those, inturn, give rise to algorithmic routines, not available in any of the previous phases of the process in question. While the logical substantiation of the point of this essay is a well-established result of logico-semantic inquiries, its empiricalclaim, based on historical evidences, remains open for discussion. Hence the author’s intention to address philosophers and historians of science, and to encourage their critical responses. (shrink)

The aim of this article is twofold. First, it is a theoretical and empirically based contribution to the branch of research that studies enabling conditions of human sense-making. It demonstrates the value of a coherent ecological framework, based on dialogism and interactivity for the study of sense-making, problem-solving and task performance in naturalistic contexts. Second, it presents a promising method for the analysis of cognitive activities, Cognitive Event Analysis, with which we investigate real-life medical interactions, especially the emergence of insights (...) in procedural task performance in emergency medicine. We show how sense-making and insights are accomplished by medical teams when they integrate cultural expertise, professional skills, inter-bodily dynamics, material constraints and affordances within the environment, i.e. when local co-action is embedded in socio-cultural patterns of behaviour.

Contemporary knowledge systems have given too much importance to visual symbols, the written word for instance, as the repository of knowledge. The primacy of the written word and the representational world built around it is, however, under debate—especially from recent insights derived from cognitive science that seeks to bring back action, intent and emotion within the core of cognitive science (Freeman and Nunez in J Consciousness Stud 6(11/12), 1999). It is being argued that other sensory experiences, apart from the (...) visual, along with desires (or intent) and emotions—like pain, pleasure, sorrow or joy—constitute equally important building blocks that shape an individual’s cognition of the world around. This multi-sensory cognition colored by emotions inspire action and hence is valid knowledge. This is probably nowhere more apparent than in the world of the visually impaired. Deprived of visual sensory capability, they have to perforce depend on other senses. But the dominant discourse in wider society plays a major role in determining what they (the blind) can do. A society built around visual symbols and the written word underplays other elements of cognition and in the process undervalues them. This also gets reflected in the construction of social artifacts of various kinds, such as the educational certification system (The Braille system is an attempt to make the written world accessible to the blind through tactile signals—so that words are ‘felt’ and ‘read.’ But it is quite cumbersome. For instance, even a blind highly skilled at writing in Braille would not be able to match the writing speed of an ordinary visually endowed literate person. Effective and efficient computer-based voice–text–voice converters might solve this problem better.)-based primarily on skills over the written word. Linguistic ability becomes most valuable and at another level the written word gets salience over the spoken word. The blind hardly has a chance, therefore, except through concessions or piety. A practice built around the imagery of an empowered blind person, therefore, must depart from mainstream conceptualization—for power is derived from what one has rather than from what one lacks. It must begin by tapping and valorizing one’s own endowments. This paper is an attempt to identify such a departure based on the experience of Blind Opera—a theatre group of the blind working in Kolkata, India. It seeks to provide an exposition in written word of an experience that can only be partially captured within the confines of a text. It is an incomplete account, therefore, and may be taken as an attempt to reach out and seek an exchange of experiences and insights. (shrink)

‘Dira’ is a novel experimental paradigm to record combinations of behavioural and metacognitive measures for the creative process. This task allows assessing chronological and chronometric aspects of the creative process directly and without a detour through creative products or proxy phenomena. In a study with 124 participants we show that (a.) people spend more time attending to selected versus rejected potential solutions, (b.) there is a clear connection between behavioural patterns and self-reported measures, (c.) the reported intensity of Eureka (...) experiences is a function of interaction time with potential solutions, and (d.) experiences of emerging solutions can happen immediately after engaging with a problem, before participants explore all potential solutions. The conducted study exemplifies how ‘Dira’ can be used as an instrument to narrow down the moment when solutions emerge. We conclude that the ‘Dira’ experiment is paving the way to study the process, as opposed to the product, of creative problem solving. (shrink)

The article "What works when working with athletes" by Fifer, Henschen, Gould, and Ravizza offers an interesting array of information and insights used by three highly experienced applied sport psychology consultants. This response article, however, contends that it may be possible to glean a further, and crucial, level of understanding by exploring the metacognition behind the selection of such courses of action. This may be provided through applied cognitive task analysis techniques to access the cognitive mechanisms underpinning professional (...) practice. A suggested research direction is to use ACTA techniques such as in-depth interviews and cognitive mapping with highly experienced applied sport psychology consultants. Specifically, these techniques would enable readers to access judgments and decisions, attentional demands, critical cues and patterns, and problem solving strategies. This level Of understanding may help to establish how these cognitive processes impact on the support provided to clients, and in turn, assist in developing more conceptually rigorous training methods.

Objective: To evaluate one ethics rounds model by describing nurses’ and doctors’ experiences of the rounds. Methods: Philosopher-ethicist-led interprofessional team ethics rounds concerning dialysis patient care problems were applied at three Swedish hospitals. The philosophers were instructed to promote mutual understanding and stimulate ethical reflection, without giving any recommendations or solutions. Interviews with seven doctors and 11 nurses were conducted regarding their experiences from the rounds, which were then analysed using content analysis. Findings: The goal of the rounds was partly (...) fulfilled. Participants described both positive and negative experiences. Good rounds included stimulation to broadened thinking, a sense of connecting, strengthened confidence to act, insight into moral responsibility and emotional relief. Negative experiences were associated with a sense of unconcern and alienation, as well as frustration with the lack of solutions and a sense of resignation that change is not possible. The findings suggest that the ethics rounds above all met the need of a forum for crossing over professional boundaries. The philosophers seemed to play an important role in structuring and stimulating reasoned arguments. The nurses’ expectation that solutions to the ethical problems would be sought despite explicit instructions to the contrary was conspicuous. Conclusion: When assisting healthcare professionals to learn a way through ethical problems in patient care, a balance should be found between ethical analyses, conflict resolution and problem solving. A model based on the findings is presented. (shrink)

When asked to explain their solutions to a problem, both adults and children gesture as they talk. These gestures at times convey information that is not conveyed in speech and thus reveal thoughts that are distinct from those revealed in speech. In this study, we use the classic Tower of Hanoi puzzle to validate the claim that gesture and speech taken together can reflect the activation of two cognitive strategies within a single response. The Tower of Hanoi is a well‐studied (...) puzzle, known to be most efficiently solved by activating subroutines at theoretically defined choice points. When asked to explain how they solved the Tower of Hanoi puzzle, both adults and children produced significantly more gesture‐speech mismatches—explanations in which speech conveyed one path and gesture another—at these theoretically defined choice points than they produced at non‐choice points. Even when the participants did not solve the problem efficiently, gesture could be used to indicate where the participants were deciding between alternative paths. Gesture can, thus, serve as a useful adjunct to speech when attempting to discover cognitive processes in problem‐solving. (shrink)

This article proposes a unified framework for understanding creative problem solving, namely, the explicit–implicit interaction theory. This new theory of creative problem solving constitutes an attempt at providing a more unified explanation of relevant phenomena (in part by reinterpreting/integrating various fragmentary existing theories of incubation and insight). The explicit–implicit interaction theory relies mainly on 5 basic principles, namely, (a) the coexistence of and the difference between explicit and implicit knowledge, (b) the simultaneous involvement of implicit and explicit processes in (...) most tasks, (c) the redundant representation of explicit and implicit knowledge, (d) the integration of the results of explicit and implicit processing, and (e) the iterative (and possibly bidirectional) processing. A computational implementation of the theory is developed based on the CLARION cognitive architecture and applied to the simulation of relevant human data. This work represents an initial step in the development of process-based theories of creativity encompassing incubation, insight, and various other related.. (shrink)

We trace how cognition arises beyond the skin. Experimental work on insight problem solving is used to examine how external artifacts can be used to reach the goal of assembling a ‘cheap necklace’. Instead of asking how insight occurs ‘in the head’, our participants in Experiment 1 can either draw solution attempts or manipulate real objects. Even though performance with real chain links is significantly more successful than on paper, access to objects does not make this insight (...) problem simple: objects themselves do not shape cognition. This challenges extended mind views. While failure often results from the inappropriate application of hill-climbing, material artifacts can trigger solutions. In Experiment 2, we used ‘open link’ conditions of the concretized problem to prompt participants to act. Solutions arrived via insight, serendipity, or trial-and-error. By investigating how objects are used, we show that they do more than supplement neural events. Rather, participants monitor and anticipate the effects of action within an organism-environment system. By analogy, language too draws on experience of monitoring real-time effects as bodily dynamics play out in a normative and cultural world. In engaging with public language, it is likely that verbal patterns function by constraining anticipatory cognitive processes. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Kant’s Theory of ActionLara DenisRichard McCarty. Kant’s Theory of Action. Oxford-New York: Oxford University Press, 2009. Pp. xxiv + 250. Cloth, $74.00.This significant, stimulating contribution to Kantian practical philosophy strives to interpret Kant’s theory of action in ways that will increase readers’ understanding and appreciation of Kant’s moral theory. Its thesis is that Kant combines metaphysical freedom and psychological determinism: our actions within the phenomenal world (...) are causally determined by our prior psychological states in that world and are appearances of our free action in the noumenal world. McCarty argues for a metaphysical, “two-worlds” interpretation of Kant’s transcendental distinction between appearances and things in themselves over epistemological or methodological “two-standpoints” interpretations familiar from Christine Korsgaard [End Page 533] and Henry Allison (along the way, McCarty also challenges Allison’s “Incorporation Thesis”). Some of the book’s arguments are textual, displaying perceptive readings of Kant’s lecture notes, published works, and philosophical influences. Others primarily concern the philosophical plausibility or moral tenability of various positions one might attribute to Kant. The book’s greatest strength is McCarty’s positive account of Kant’s theory of action. He presents a coherent, even elegant, two-worlds model. His interpretations of maxims, incentives, empirical character, and Gesinnung are insightful.The book’s first two chapters introduce McCarty’s understanding of maxims and incentives and begin tackling what he calls “the problem of justification and explanation.” Chapter 3 defends the claim that Kant embraced psychological determinism. Chapters 4 and 5 present McCarty’s two-worlds interpretation of the transcendental distinction, defend it from objections, and argue for its superiority over two-standpoint interpretations. Chapter 6 focuses on moral motivation, presenting respect for the moral law as an incentive capable of explaining morally justified actions, and distinguishing between morally worthy and virtuous action so as to defend Kant’s ethics from common objections. Chapter 7 similarly disentangles notions of a good will and virtue, provocatively claiming that all human agents have both a good will and virtue. The main task of chapter 7, however, is analysis of the radical evil in human nature. Chapter 8 raises questions about Kant’s conception of the highest good—particularly, the afterlife in which we are to continue our moral progress—as an object of rational hope.I read the book’s main argument as follows:1. Kant’s theory of action must solve “the problem of justification and explanation”: it must show how the reasons that justify a judgment that one ought to do something can also explain one’s doing it. Kant’s theory of action must solve this problem because if what justifies an action cannot also explain it, such justification is “irrelevant.” Only if our actions are explicable in terms of practical reasoning is justification of action by practical reasoning (e.g. by reference to hypothetical or categorical imperatives) “relevant” to our conduct. The problem of justification and explanation arises as it does within Kant’s ethics because Kant holds that pure reason is capable of issuing in action; yet he also holds that human beings and other imperfectly rational agents do not invariably act as we recognize we ought. So we cannot explain our acting as we ought (when we do) simply by appeal to “ought implies can,” internalism, or “the causality of freedom.”2. Psychological determinism, combined with a metaphysical interpretation of Kant’s transcendental distinction, allows Kant to solve the problem of justification and explanation. Through a timeless, free act in the noumenal world, we each fix our empirical character, which serves as the “causal law” for our actions in the phenomenal world. Maxims, which function as both major premises in practical syllogisms and rules of our empirical characters, provide bases for both the imperatival justifications and motivational explanations of human actions. The “logical force” of a maxim justifies action on it; the “psychological force” of the maxim—specifically, of the incentive incorporated into the maxim—explains action on it.3. Psychological determinism is compatible with and beneficial for Kant’s moral theory. Most crucially, it is compatible with the freedom necessary for moral agency and responsibility.4.

In recent years, business ethics and economic scholars have been paying greater attention to the development of commons organizing. The latter refers to the processes by which communities of people work in common in the pursuit of the common good. In turn, this promotes commons organizational designs based on collective forms of common goods production, distribution, management and ownership. In this paper, we build on two main literature streams: the ethical approach based on the theory of the common good of (...) the firm in virtue ethics and the economic approach based on the theory of institutions for collective action developed by Ostrom’s research on common-pool resources to avert the tragedy of the commons. The latter expands to include the novel concepts of new commons, “commoning” and polycentric governance. Drawing on the analysis of what is new in these forms of organizing, we propose a comprehensive model, highlighting the integration of two sets of organizing principles—common good and collective action – and five problem-solving processes to explain the main dimensions of commons organizing. We contribute to business ethics literature by exploring the convergence between the ethical and economic approaches in the development of a commons organizing view. (shrink)

Due to the development of the Chinese economy, the consolidation of national power worldwide, and the increasing frequency of economic and cultural exchanges with foreign countries, the number of people from various countries who travel to China to engage in exchanges has increased significantly. Given the development of economic globalization, the acceleration of the process of educational internationalization represents a general trend in higher education development and a common requirement for universities. In addition to education, international students also experience cross-cultural (...) adaptation, that is, behavioral adaptation or changes that occur in people in response to changes in their home country, whether in the form of external or internal cultural adaptation. For international students, the problem of cross-cultural adaptation not only hinders their learning progress but also affects their psychology and living conditions. This article explains the construction of Habermas’s theory of communication action. According to this theory, the purpose of communication is to coordinate the common actions of actors, and this coordination is achieved through mutual communication, which is mediated by language. The article also discusses the cross-cultural adaptation experienced by international students in Chinese universities and highlights the importance of developing educational services for international students in the context of international education. Studies have shown that female students exhibit slightly worse psychological adaptation than male students and female students have a slightly higher rate of depression rate than male students. An interpersonal study of 120 international students traveling to China found that most of these students were able to adapt in terms of their interpersonal relationships. To solve the problems associated with cross-cultural adaptation of international students in China, some countermeasures have been proposed, mainly including active participation in interpersonal communication, an enhanced understanding of the new culture, and the amplification of cultural identity.

As a committee of the National Academy of Engineering recognized, ethics education should foster the ability of students to analyze complex decision situations and ill-structured problems. Building on the NAE’s insights, we report about an innovative teaching approach that has two main features: first, it places the emphasis on deliberation and on self-directed, problem-based learning in small groups of students; and second, it focuses on understanding ill-structured problems. The first innovation is motivated by an abundance of scholarly research that supports (...) the value of deliberative learning practices. The second results from a critique of the traditional case-study approach in engineering ethics. A key problem with standard cases is that they are usually described in such a fashion that renders the ethical problem as being too obvious and simplistic. The practitioner, by contrast, may face problems that are ill-structured. In the collaborative learning environment described here, groups of students use interactive and web-based argument visualization software called “AGORA-net: Participate – Deliberate!”. The function of the software is to structure communication and problem solving in small groups. Students are confronted with the task of identifying possible stakeholder positions and reconstructing their legitimacy by constructing justifications for these positions in the form of graphically represented argument maps. The argument maps are then presented in class so that these stakeholder positions and their respective justifications become visible and can be brought into a reasoned dialogue. Argument mapping provides an opportunity for students to collaborate in teams and to develop critical thinking and argumentation skills. (shrink)

Intelligent mental representations of physical, cognitive and social environments allow humans to navigate enormous search spaces, whose sizes vastly exceed the number of neurons in the human brain. This allows us to solve a wide range of problems, such as the Traveling Salesperson Problem, insight problems, as well as mathematics and physics problems. As an area of research, problem solving has steadily grown over time. Researchers in Artificial Intelligence have been formulating theories of problem solving for the last 70 (...) years. Psychologists, on the other hand, have focused their efforts on documenting the observed behavior of subjects solving problems. This book represents the first effort to merge the behavioral results of human subjects with formal models of the causative cognitive mechanisms. The first coursebook to deal exclusively with the topic, it provides a main text for elective courses and a supplementary text for courses such as cognitive psychology and neuroscience. (shrink)

Whether the (...) condition was a ruptured intracranial aneurysm with brain death or a patient with far advanced cancer struggling with the choice between experimental chemotherapy or choosing comfort therapy at home surrounded by family for the remaining days of life, the moral courage required to provide the best guidance was considerable. In my early years of practice I didn’t call my actions in these situations “courageous” nor were there moral “guidelines” providing a blueprint. I knew I responded with empathy and compassion and that this ability had a lot to do with being raised in a religious or spiritual home. At the same time, I suspected that some of the lack of empathy and compassion I witnessed in some of my colleagues was related to the very training programs of physicians. This essay traces the origin of my moral and ethical concerns about medical education and my intention to reinvigorate the spiritual or existential voice in medicine.An early life experience had a great deal to do with shaping my moral development. At age seven my family traveled through the West Indies. My father’s amateur radio hobby meant that at every stop we would be greeted by one of his radio contacts. One stop in particular was life changing.Port au Prince, Haiti was an unknown place to this seven year–old, but to say it was a culture shock to a boy from Kansas would be an understatement of epic proportions. It was during this visit that I experienced true poverty in its most blatant form. In downtown Port au Prince I saw limbless beggars and the deformed from polio and malnutrition. But it was the sight of the garbage dump near the center of town that changed my world forever. There, among piles of detritus, I saw children and families making their home in the dump. They had hollowed out a sort of cavern in the piles of trash that served as a place of refuge from both the rain and the sun.This experience in many ways has served as a framework and background for my life. Although seen through the eyes of a seven year–old, the picture can only be adequately understood within the context of being raised by religiously faithful parents, parents free of hypocrisy whose lives personified the best in Christian virtues and practices. These early experiences planted the seeds that would only fully blossom some 60 years later.Medical school was a demanding but exhilarating experience. Each day was a day of discovery … anatomy, physiology, pathology … all subjects opening up a whole new world to explore. Internal medicine suited me best since it was the specialty that most closely integrated all the basic sciences necessary to arrive at a diagnosis. I loved the elegance of endocrinology in particular where a given hormone mediator could cause widely different effects if present in excess or completely absent. But I was in the end drawn to cardiology since it combined complex physiology with my avocation, the love of running.There was, however, a disturbing aspect of medicine education that I observed affecting many of my classmates. Although I can vividly recall the enthusiasm that all of us shared as we donned our white coats for the first time and envisioned a future of caring for our patients, things gradually and insidiously changed over the next four years. The altruism and empathy that was so evident in the early years gradually lessened as graduation approached. I could not help being struck by this change and wondered at the time why that should happen. I had no insight then that what I had observed was a well recognized consequence of the medical school experience. I’m sure that the passage from professional training to practice in... (shrink)

We trace how cognition arises beyond the skin. Experimental work on insight problem solving is used to examine how external artifacts can be used to reach the goal of assembling a `cheap necklace'. Instead of asking how insight occurs `in the head', our participants in Experiment 1 can either draw solution attempts or manipulate real objects . Even though performance with real chain links is significantly more successful than on paper, access to objects does not make this (...) class='Hi'>insight problem simple: objects themselves do not shape cognition. This challenges extended mind views. While failure often results from the inappropriate application of hill-climbing, material artifacts can trigger solutions. In Experiment 2, we used `open link' conditions of the concretized problem to prompt participants to act . Solutions arrived via insight, serendipity, or trial-and-error. By investigating how objects are used, we show that they do more than supplement neural events. Rather, participants monitor and anticipate the effects of action within an organism-environment system. By analogy, language too draws on experience of monitoring real-time effects as bodily dynamics play out in a normative and cultural world. In engaging with public language, it is likely that verbal patterns function by constraining anticipatory cognitive processes. (shrink)

An intuitive and appealing way to characterize problem solving is as the application of constraints which reduce the problem-solution space. Any advantage offered by interdisciplinary problem solving would then plausi- bly derive from the integration of constraints from the fields involved. We propose an account of interdisciplinary problem solving which treats the integration of constraints as an iterative process. Appealing to a general- ization of entity-activity dualism from mechanical explanation, we extend the accounts of Bechtel and of Craver to non-hierarchical, (...) non-life-science, interdisciplinary problem-solving. Integration of disciplines occurs at the level of fields and their explanatory frameworks. (shrink)

The general thesis that science is essentially a problem-solving activity is extended to the development of new fields. Their development represents a research strategy for generating and solving new unsolved problems and solving existing ones in related fields. The pattern of growth of new fields is guided by the central problems within the field and applicable problems in other fields. Proponents of existing research traditions welcome work in new fields, if they believe it will increase the problem-solving effectiveness of their (...) tradition. Correspondingly, researchers in new fields will graft their work onto established traditions, if they believe it will augment the problem-solving effectiveness of their work. The above claims are defended through using the development of paleomagnetism as a case study. (shrink)

Insight problem solving was investigated with the matchstick algebra problems developed by Knoblich, Ohlsson, Haider, and Rhenius (1999). These problems are false equations expressed with Roman numerals that can be made true bymoving one matchstick. In a first group participants examined a static two-dimensional representation of the false algebraic expression and told the experimenter which matchstick should be moved. In a second group, participants interacted with a three-dimensional representation of the false equation. Success rates in the static group for (...) different problem types replicated the pattern of data reported in Knoblich et al. (1999). However, participants in the interactive group were significantly more likely to achieve insight. Problem-solving success in the static group was best predicted by performance on a test of numeracy, whereas in the interactive group it was best predicted by performance on a test of visuo-spatial reasoning. Implications for process models of problem solving are discussed. (shrink)

In this article, we propose a new account concerning the interlock between intentions and motor representations (henceforth: MRs), showing that the interface problem is not as deep as previously proposed. Before discussing our view, in the first section we report the ideas developed in the literature by those who have tried to solve this puzzle before us. The article proceeds as follows. In Sections 2 and 3, we address the views by Butterfill and Sinigaglia, and Mylopoulos and Pacherie, respectively, and (...) argue that both solutions entail a translation between representational formats, which both accounts aim to avoid. In Section 4, we present our brand‐new claim, according to which intentions and MRs partially share the same motor format, inasmuch as executable action concepts are naturally represented in the agent's motor system together with the action's outcomes. Indeed, since intentions are constituted by executable action concepts and since there is evidence that action concepts are represented (and, thus, built) in the same motor format as action outcomes, the interlock between intentions and MRs no longer constitutes a problem. Then, in Section 5, we report empirical evidence in support of our claim, and before concluding, in Section 6 we briefly clarify our relations with two very recent accounts that criticized the proposals by Mylopoulos and Pacherie and Butterfill and Sinigaglia: Shepherd's and Burnston's. Finally, in Section 7, we offer some remarks about the philosophical idea defended here. The basic insight is that interface without translation is possible because action concepts are such stuff as MRs are made on. (shrink)

Problem of truth and reality is age old in the field of philosophy as well as in the field of science. People very often confuse between ‘Truth’ and ‘Reality’ Most people think them to be one and the same, but there are differences. Whatever exist is real, reality and existence are interchangeable words. We can say truth, which is unchangeable and reality, which exist but change. False, which is not exist at all. People have suggested various taste to decide the (...) truth falsity of our description of reality. Some suggested Pragmatic theory and some other have suggested Coherence as a test of truth. Realism is also an ontological theory and has been probably the most ancient one. According to ancient man, real is that which perceived. Latter on, due to religious impact the knower became more important then the knowing object. Barkeley developed an extreme position that the objective material world does not exist at all. Dewey has developed the position called Instrumentalism. Halt, Perry, Marvin, Pitkin are the chief advocates of this position. Philosophers such as Darke, Lovejoy, Cellars, and Santayana held a position of Critical Realism. These people hold that mind does not see the object directly as they are but only through their representatives, as regards the object of knowledge is concerned, the Neo Realist are monist while Critical Realist are dualist. Indian rationalist philosopher Dr. D.D. Bandiste introduces a new concept of reality Radical Realism. He proved that knowledge change the knower not the object. to him every new knowledge make some change or other inthe knowing person. Epistemological position of john Dewey called instrumentalism. According to him knowledge is an instrument of action and a meaningful action is always of a problem-solving type. Every knowledge is an instrument to serve some need or other, neither is any knowledge final, nor is any truth final. Not only everything in the world is changing, their mutual relations also change. Knowledge is not a goal, but only a instrument to achieve this or that goal. In my paper I haves discussed various theories regarding whether knowledge change the object known. In this contest I have discussed varieties of realism, Idealismand so on, but importantly I have also discussed a new theory Radical Realism. (shrink)

Learning to solve a class of problems can be characterized as a search through a space of hypotheses about the rules for solving these problems. A series of four experiments studied how different learning conditions affected the search among hypotheses about the solution rule for a simple computational problem. Experiment 1 showed that a problem property such as computational difficulty of the rules biased the search process and so affected learning. Experiment 2 examined the impact of examples as instructional (...) tools and found that their effectiveness was determined by whether they uniquely pointed to the correct rule. Experiment 3 compared verbal directions with examples and found that both could guide search. The final experiment tried to improve learning by using more explicit verbal directions or by adding scaffolding to the example. While both manipulations improved learning, learning still took the form of a search through a hypothesis space of possible rules. We describe a model that embodies two assumptions: the instruction can bias the rules participants hypothesize rather than directly be encoded into a rule; participants do not have memory for past wrong hypotheses and are likely to retry them. These assumptions are realized in a Markov model that fits all the data by estimating two sets of probabilities. First, the learning condition induced one set of Start probabilities of trying various rules. Second, should this first hypothesis prove wrong, the learning condition induced a second set of Choice probabilities of considering various rules. These findings broaden our understanding of effective instruction and provide implications for instructional design. (shrink)

Insight problems are difficult because the initially activated knowledge hinders successful solving. The crucial information needed for a solution is often so far removed that gaining access to it through restructuring leads to the subjective experience of “Aha!”. Although this assumption is shared by most insight theories, there is little empirical evidence for the connection between the necessity of restructuring an incorrect problem representation and the Aha! experience. Here, we demonstrate a rare case where previous knowledge facilitates (...) the solving of insight problems but reduces the accompanying Aha! experience. Chess players were more successful than non‐chess players at solving the mutilated checkerboard insight problem, which requires retrieval of chess‐related information about the color of the squares. Their success came at a price, since they reported a diminished Aha! experience compared to controls. Chess players’ problem‐solving ability was confined to that particular problem, since they struggled to a similar degree to non‐chess players to solve another insight problem (the eight‐coin problem), which does not require chess‐related information for a solution. Here, chess players and non‐chess players experienced the same degree of insight. (shrink)

In a familiar interpretation, the Non-Identity Problem claims that persons whose existence depends on a seemingly harmful action cannot in fact be harmed through such an action. It is often objected that the persons in question can nevertheless be wronged through a violation of their rights. However, this objection seems to fail because these persons would readily waive any violated right in order to come into existence. The present article will analyze this Waiver Counter Argument in (...) detail and show why it does not succeed. First, it is necessary to distinguish between a prospective and a retrospective waiver scenario. In the prospective scenario an imagined person must consider whether she wants to waive a right in order to come into existence. In the retrospective scenario a person is asked whether she would prefer a wronged existence to never having been born. In both scenarios the conditions of a legitimate waiver of rights are not met, but for different reasons. On this basis, an argument against NIP can be developed. (shrink)

Social action projects provide opportunities for students to practice civic skills by learning about pressing social issues and taking action to address them. So to explore the texture of such projects, this paper illustrates how the pedagogy guiding them can support students to experience their agency as individuals, develop their knowledge of their broader social contexts, and provide opportunities for action. While the value of a relationship between individual agency, social knowledge, and action are richly described (...) in theoretical texts, this paper shows how such principles are extended in one social action project that unfolded in an eighth grade class. Through the use of qualitative methods, I documented and analyzed the project. I share my analysis so to bring teachers and students’ lived experiences with social action projects to light. The paper concludes with recommendations for educators when envisioning and enacting social action projects. (shrink)

Performance Generating Systems (PGS) are rule- and task-based approaches to improvisation on stage in theatre, dance, and music. These systems require performers to draw on predefined source materials (texts, scores, memories) while working on complex tasks within limiting rules. An interdisciplinary research team at a large Western Canadian university hypothesized that learning to sustain this praxis over the duration of a performance places high demands on executive functions; demands that may improve the performers’ executive abilities. These performers need to continuously (...) shift attention while remaining responsive to embodied and environmental stimuli in the present, they are required to inhibit automated responses and impulses using the rules of the system, and they strive towards addressing multitasking challenges with fluidity and flexibility. This study set out to test the mentioned hypothesis deductively and identify mediating processes inductively, using mixed empirical methods. In a small sample experiment with a control group (28 participants; 15 in intervention group, 13 in control group), standardized quantitative tests of executive functions (D-KEFS) were administered before and after an eight-week intervention. Participant-reported qualitative observations from the praxis were also collected throughout the intervention for grounded analysis. Within the limitations of small sample data, we found both statistically significant and trending effects on inhibition, problem-solving initiation, fluidity, and cognitive flexibility. Examining the mediating process, we found that participants experienced significant challenges sustaining the practice halfway through the intervention. The participant-reported solutions to these challenges, which emerged as the strongest behavioural patterns when coding the qualitative data to saturation, were strategies of problem-solving and of re-directing attention. These strategies support and advance our understanding of the effects measured in the standardized tests. In terms of application, our results identify characteristics of PGS that could potentially maintain and strengthen executive functions over and above less demanding performing arts interventions. The results also deliver new insight into how PGS works, which may contribute to the development and teaching of this artistic practice. (shrink)

Climate change is one of the greatest challenges that human societies have ever faced. After a late start, it is by now rather intensely debated and analysed also in the social sciences and humanities, though mostly through overly generic explanations in terms of an instrumental relation to nature, of capitalist expansion drives or of the human longing for comfort. In contrast, this article concentrates on the socio-political transformations since the middle of the 20th century, which have been referred to (...) as the ‘Great Acceleration’ in the use of biophysical resources and in environmental degradation. It provides an analysis of the socio-political mechanisms that brought the resource-intensive path of social development about, showing how Western democratic societies tended to ‘solve’ difficult social problems by means of a triple displacement: onto other societies; onto nature and the planet; and into the future. As an unintended consequence, this displacement politics led to the globalization of resource-intensive development and to a planetary situation in which, at least as it appears in much of current debate, no further displacement is possible. The article concludes with insights for a more adequate approach to social phenomena of large scale and long duration in social theory. (shrink)

Rather than being random deviation, student errors can be a source of insight into the nature of student difficulties. This paper reports on (and offers pedagogical advice concerning) many common student errors in the construction of proofs, in the application of inference and replacement rules, and in the choice of proof strategies. In addition, a detailed description of the bottom-up strategy for “working backwards” is supplied, along with a discussion of the main difficulties students face when trying to solve (...) proofs in this fashion. Ultimately, it is argued that students can employ both top-down and bottom-up proofs strategies by making use of a graphic proof representation. (shrink)

There are two opposed theories which attempt to account for the processes of problem solution involved in learning and intelligence. The former is neural in its basis and postulates the existence of a bare connection as a bonding or linkage of two experiences. The second theory, that of gestalt, implies that learning or apprehension involves a relationship of the parts of the experience to each other as well as to the whole. While these psychological schools are exclusive of and opposed (...) to each other, yet they are merely extremes of what actually exists. There is a minimum level of learning in which associationism is operative and a maximum intellectual level at which explicit relationships predominate. An examination of experimental results will show this to be the case. The results of conditioned reflex experiments in both animals and man appear to show that there is present nothing beyond arbitrary linkage or bonding between the parts of the situation involved. On the other hand, one finds a certain degree of implicit meaning involved in perceptual situations—the level of animal achievement—as well as a certain measure of transfer of meaning. Explicit meanings may be related by means of word symbols involving the principle of the concept through the medium of speech, and this is only arrived at by human beings. We may regard these higher levels as “emergents” from the level of bonding or linkage. (shrink)

Action research has repeatedly demonstrated how it can facilitate problem solving and change in many settings through a process of collaboration which is driven by the community at the heart of the research. The ethical review of action research can be challenging for action researchers and research ethics committees. This paper explores how seven ethical principles can be used by action researchers and research ethics committees as the basis for ethical review. This paper concludes by (...) offering some suggestions for a way forward for both action researchers and research ethics committees. (shrink)

Sources of difficulty in insight problem-solving have been identified, but current theories are less successful at explaining discovery of solution ideas. Here, we explore the role of expertise in promoting insight. In Experiment 1, experienced designers and financiers solved visual and verbal problems. Expertise did not influence solution rates for verbal problems, but designers solved more visual problems than financiers, despite similar incorrect initial attempts. In Experiment 2, experienced and novice designers attempted problems either unconstrained, prevented from drawing, (...) or sitting on their hands to prevent drawing and gesture. Hand and drawing constraints removed the positive benefits of expertise. Experienced designers appear to solve visual problems by using strategies to explore the visuo-spatial environment in search of new representations. The results indicate that expert strategic knowledge can be a source of insight. They also show that strategic transfer of expertise to far domains can be achieved. (shrink)

Habitual actions have a history of practice and repetition that frees us from attending to what we are doing. Nevertheless, habitual actions seem to be intentional. What does account for the intentionality of habitual actions if they are automatically performed and controlled? In this paper, we address a possible response to a particular version of this issue, that is, the problem of understanding how the intention to execute a habitual action, which comes in a propositional format, interlocks with motor (...) representations, which come in a motoric-pragmatic format. In order to solve this issue, we propose an account according to which the propositional intentions and the motor representations related to our habitual actions interlock through executable action concepts. This allows us to maintain that habitual actions can be, at the same time, automatically initiated, performed, and controlled and, still, intentional. (shrink)

We report an experiment investigating the “special-process” theory of insight problem solving, which claims that insight arises from non-conscious, non-reportable processes that enable problem re-structuring. We predicted that reducing opportunities for speech-based processing during insight problem solving should permit special processes to function more effectively and gain conscious awareness, thereby facilitating insight. We distracted speech-based processing by using either articulatory suppression or irrelevant speech, with findings for these conditions supporting the predicted insight facilitation effect relative (...) to silent working or thinking aloud. The latter condition was included to investigate the currently contested effect of “verbal overshadowing” on insight, whereby thinking aloud is claimed to hinder the operation of special, non-reportable processes. Whilst verbal overshadowing was not evident in final solution rates, there was nevertheless support for verbal overshadowing up to and beyond.. (shrink)

Language and thought share a unitary cognitive activity, addressed by an interpretative function. This interpretative effort reveals the assonance between the attribution of meaning to an utterance and the discovery of a solution via restructuring in insight problem solving. We suggest a view of complex integrated analytical thinking, which assumes that thinking processes information in different ways, depending on the characteristics of the tasks the subject has to solve, so that reasoning results in a stepwise, rule-based process or in (...) a widespread activity of search where implicit parallel processes are also involved. We investigated the interrelationship between language and thought in insight problem solving, in both its positive (Experiments 1 and 3) and its negative effects (Experiment 2). Our results are discussed in the light of the debate on dual processing theories. (shrink)
