The theoretical framework laid out by Findlay & Walker has direct implications for central topics in research on saccades in reading and other cognitive activities and these in turn may also have implications to be considered in the context of Findlay & Walker's model. The present commentary focuses on the problem of selecting a target for a saccade. It is argued that there are indirect and direct top-down influences on this process and that direct influences are not adequately represented (...) in Findlay & Walker's theory. (shrink)

A critical issue in perception is the manner in which top‐down expectancies guide lower level perceptual processes. In speech, a common paradigm is to construct continua ranging between two phonetic endpoints and to determine how higher level lexical context influences the perceived boundary. We applied this approach to music, presenting participants with major/minor triad continua after brief musical contexts. Two experiments yielded results that differed from classic results in speech perception. In speech, context generally expands the category (...) of the expected stimuli. We found the opposite in music: The major/minor boundary shifted toward the expected category, contracting it. Together, these experiments support the hypothesis that musical expectancy can feed back to affect lower‐level perceptual processes. However, it may do so in a way that differs fundamentally from what has been seen in other domains. (shrink)

Despite continuing interest in the impact of employees’ emotional intelligence in explaining for their engagement and emotional exhaustion, there are still large gaps in our understanding of the role played by contextual EI-related factors, such as an EI-related organizational culture and supervisors’ emotionally intelligent behavior. This two-study research approaches EI from a macro-level perspective, attempting to address three objectives: to develop and define a theoretical concept of EI-supportive organizational culture, to develop and validate measures of organizations’ EI-related values and practices, (...) and to investigate their top-down effect on employee engagement and exhaustion, via supervisor EI-related behavior. In the first study, we conceptualize and develop measures of perceived EI-related organizational values and human resource management practices, as separate yet related dimensions of organizations’ EI-related culture, and test their validity. In the second study, we build on the job demands-resources theory and Ability-Motivation-Opportunity framework to develop and test a model of the process links between perceived EI-related values and HRM practices and employee engagement and exhaustion, using a large sample of employees across industries in the USA workforce. In line with our hypotheses, the findings suggest that EI-supportive HRM practices have a top-down effect on employee engagement and exhaustion via supervisor EIB, whereas low regard for emotions values has a top-down effect on employee exhaustion via supervisor emotional misbehavior. Results are discussed in the context of the JD-R theory, AMO framework, and the EI literature. (shrink)

This paper explores the circumstances that influence whether managers in the public services manipulate the measurement information that is used to assess performance; and if they do, what level of deception they might use.

A Delphi survey and the collection of critical incidents through interviews are used to identify possible configurations of contexts–mechanisms–outcomes that provide possible explanations of information manipulation. A number of these configurations are discussed. In a later stage of the project (...) these configurations will be further tested through another Delphi survey, with the intention of developing proposals for improved governance of performance measurement systems in the public services.

Pickering & Garrod's (P&G's) model is an innovative and important step in the study of naturalistic language. However, the simplicity of its mechanisms for dialogue coordination may be overstated and the hypothesized direct priming channel between interlocutors' situation models is questionable. A complete specification of the model will require more investigation of the role of top-down inhibition among representations.

In this paper I want to discuss the implications of adopting different general philosophical approaches for assessing the relation between perception and imagination. In particular, I am interested in different views resulting from ‘top down’ and ‘bottom up’ approaches to cognition. By ‘top down’ approaches I meanapproaches that conceive of cognition as a process or activity that is guided by intellectual or conceptual (‘top’) elements. (I consider broadly speaking Kantian accounts typical.) By ‘bottom up’ approaches I mean approaches that conceive (...) of cognition as a process that emerges from perceptual or embodied (‘bottom’)elements of cognition. (I consider phenomenological and situated cognition accounts typical.) My considerations are framed by a particular interest in the ensuing consequences of assuming different general frameworks for integrating the issue of imagination within a theory of situated cognition.

Physics underlies all complexity, including our own existence: how is this possible? How can our own lives emerge from interactions of electrons, protons, and neutrons? This book considers the interaction of physical and non-physical causation in complex systems such as living beings, and in particular in the human brain, relating this to the emergence of higher levels of complexity with real causal powers. In particular it explores the idea of top-down causation, which is the key effect allowing the emergence of (...) true complexity and also enables the causal efficacy of non-physical entities, including the value of money, social conventions, and ethical choices.

This paper concerns top-down approaches in machine ethics. It is divided into three main parts. First, I briefly describe top-down design approaches, and in doing so I make clear what those approaches are committed to and what they involve when it comes to training an AI to behave ethically. In the second part, I formulate two underappreciated motivations for endorsing them, one relating to predictability of machine behavior and the other relating to scrutability of machine decision-making. Finally, I present three (...) major worries about such approaches, and I attempt to show that advocates of top-down approaches have some plausible avenues of response. I focus most of my attention on what I call the ‘technical manual objection’ to top-down approaches, inspired by the work of Annas (2004). In short, the idea is that top-down approaches treat ethical decision-making as being merely a matter of following some ethical instructions in the same way that one might follow some set of instructions contained in a technical manual (e.g., computer manual), and this invites sensible skepticism about the ethical wisdom of machines that have been trained on those approaches. I respond by claiming that the objection is successful only if it is understood as targeting machines that have certain kinds of goals, and it should not compel us to totally abandon top-down approaches. Such approaches could still be reasonably employed to design ethical AI that operate in contexts that include fairly noncontroversial answers to ethical questions. In fact, we should prefer top-down approaches when it comes to those types of context, or so I argue, due to the advantages I claim for them. (shrink)

The distinction between top-down and bottom-up effects is widely relied on in experimental psychology. However, there is an important problem with the way it is normally defined. Top-down effects are effects of previously-stored information on processing the current input. But on the face of it that includes the information that is implicit in the operation of any psychological process – in its dispositions to transition from some types of representational state to others. This paper suggests a way to distinguish information (...) stored in that way from the kind of influence of prior information that psychologists are concerned to classify as a top-down effect. So-drawn, the distinction is not just of service to theoretical psychology. Asking about the extent of top-down processing is one way to pose some of the questions at issue in philosophical debates about cognitive penetrability – about the extent of the influence of cognitive states on perception. The existence of a theoretically-useful perception-cognition distinction has come under pressure, but even if it has to be abandoned, some of the concerns addressed in the cognitive penetrability literature can be recaptured by asking about the extent of top-down influences on any given psychological process. That formulation is more general, since it can be applied to any psychological process, not just those that are paradigmatically perceptual. (shrink)

The question of whether cognition can influence perception has a long history in neuroscience and philosophy. Here, we outline a novel approach to this issue, arguing that it should be viewed within the framework of top-down information-processing. This approach leads to a reversal of the standard explanatory order of the cognitive penetration debate: we suggest studying top-down processing at various levels without preconceptions of perception or cognition. Once a clear picture has emerged about which processes have influences on those (...) at lower levels, we can re-address the extent to which they should be considered perceptual or cognitive. Using top-down processing within the visual system as a model for higher-level influences, we argue that the current evidence indicates clear constraints on top-down influences at all stages of information processing; it does, however, not support the notion of a boundary between specific types of information-processing as proposed by the cognitive impenetrability hypothesis.

Recent experimental work suggests that the concept of contextual fields should be generalized to allow the modulation of local information extraction by both external and internal context. The external context relates to the coherent information of the stimulus; the internal context refers to the parts of this information which are relevant for behavior. This dual interaction, present at every level of the hierarchy, requires a fundamental unit of processing more complex than a single neuron appears today. We (...) argue that the cortical column supplies the required mechanisms for a separate top-down and bottom-up processing and allows for interaction without destructive cross-talk. This flexibility might explain why the same basic architecture of a cortical column is used in the whole isocortex. (shrink)

My main purpose here is to provide an account of context selection in utterance understanding in terms of the role played by schemata and goals in top-down processing. The general idea is that information is organized hierarchically, with items iteratively organized in chunks—here called “schemata”—at multiple levels, so that the activation of any items spreads to schemata that are the most accessible due to previous experience. The activation of a schema, in turn, activates its other components, so as to (...) predict a likely context for the original item. Since each input activates its own schemata, conflicting schemata compete with (and inhibit) each other, while multiple activations of a schema raise its likelihood to win the competition. There is therefore a double movement—with bottom-up activation of schemata enabling top-down prediction of other contextual components—triggered by multiple sources. Another claim of the paper is that goals are represented by schemata placed at the highest-levels of the executive hierarchy, in accordance with Fuster’s model of the brain as a hierarchically organized perception action cycle. This account can be considered, in part at least, a development of ideas contained in Relevance Theory, though it may imply that some other claims of the theory are in need of revision. Therefore, a secondary purpose of the paper is a contribution to the analysis of that theory. (shrink)

This study adds to the growing research exploring the consequences of knowledge hiding in organizations. Drawing from the social exchange theory and the norm of reciprocity, this paper examines the direct and indirect—via distrust in supervisor—relationships between supervisor knowledge hiding and supervisee organizational citizenship behavior directed at the supervisor in the context of the Middle East. Using a supervisor–supervisee dyadic design, two-source data were obtained from 317 employees of 41 Saudi firms. The findings suggest that supervisees’ distrust in their (...) supervisors mediates the significant and negative relationship between SKH and supervisees’ OCB-S. Furthermore, the significant and positive relationship between SKH and distrust in supervisor is more pronounced for foreign workers than for local workers. This study provides empirical support and a better understanding of the existence and consequences of SKH for local and foreign workers and also discusses the theoretical and practical implications of the findings.

This study examines the educational policy related to the inclusion of ethnic minority population in the contemporary China. It has undergone three stages of the educational policy transformation, including the beginning, development and perfection stages. It is characterized by the steadiness, caution, rapidity, quality improvement, standardization and quality. Through implementing the educational policy of the inclusion of ethnic minority population, it has made retrogress and achievements, which has played a positive role in national integration, maintaining national unity and regional stability, (...) improving the academic level and cross-cultural ability of minority students, and sharing educational resources. However, in current China’s education context, the implementation of education policy is faced with some prominent problems, such as the marginalized educational identity, non-communicative education, relative separation of systems and serious cultural barriers, relative emphasis on explicit education. Therefore, it suggested to construct a new integrative and open ethnic education system, strengthen the consciousness of the united integrated education, and enhancing the bi-directionality of ethnic integration.

Conceptual knowledge is acquired through recurrent experiences, by extracting statistical regularities at different levels of granularity. At a fine level, patterns of feature co-occurrence are categorized into objects. At a coarser level, patterns of concept co-occurrence are categorized into contexts. We present and test CONCAT, a connectionist model that simultaneously learns to categorize objects and contexts. The model contains two hierarchically organized CALM modules (Murre, Phaf, & Wolters, 1992). The first module, the Object Module, forms object representations based on co-occurrences (...) between features. These representations are used as input for the second module, the Context Module, which categorizes contexts based on object co-occurrences. Feedback connections from the Context Module to the Object Module send activation from the active context to those objects that frequently occur within this context. We demonstrate that context feedback contributes to the successful categorization of objects, especially when bottom-up feature information is degraded or ambiguous. (shrink)

The phenomenon of perceptual persistence after the motion stops in shape-from-motion displays was used to study the influence of prior knowledge on the maintenance of a percept in awareness. In SFM displays an object composed of discontinuous line segments are embedded in a background of randomly oriented lines. The object only becomes perceptible when the line segments that compose the object and the lines that compose the background move in counterphase. Critically, once the movement of the line segments stops, (...) the percept of the object persists for a short period of time. In the present study, perceptual persistence for digits exceeded that reported for nonsense shapes composed of the same line segments. This result is taken as evidence that the processes involved in the persistence of SFM, and therefore sustained perception, are sensitive to top-down influences. (shrink)

Lane et al. are right: Troublesome memories can be therapeutically recontextualized. Reconsolidation of negative/traumatic memories within the context of positive/prosocial affects can facilitate diverse psychotherapies. Although neural mechanisms remain poorly understood, we discuss how nonlinear dynamics of various positive affects, heavily controlled by primal subcortical networks, may be critical for optimal benefits.

Top-down causation is often taken to be a metaphysically suspicious type of causation that is found in a few complex systems, such as in human mind-body relations. However, as Ellis and others have shown, top-down causation is ubiquitous in physics as well as in biology. Top-down causation occurs whenever specific dynamic behaviors are realized or selected among a broader set of possible lower-level states. Thus understood, the occurrence of dynamic and structural patterns in physical and biological systems presents a problem (...) for reductionist positions. We illustrate with examples of universality and functional equivalence classes how higher-level behaviors can be multiple realized by distinct lower-level systems or states. Multiple realizability in both contexts entails what Ellis calls “causal slack” between levels, or what others understand as relative explanatory autonomy. To clarify these notions further, we examine procedures for upscaling in multi-scale modeling. We argue that simple averaging strategies for upscaling only work for simplistic homogenous systems, because of the scale-dependency of characteristic behaviors in multi-scale systems. We suggest that this interpretation has implications for what Ellis calls mechanical top-down causation, as it presents a stronger challenge to reductionism than typically assumed. (shrink)

In this paper, we explore the architecture of downward causation on the basis of three central cases. We set out by answering the question of how top-down causation is possible in the universe. The universe is not causally closed, because of irreducible randomness at the quantum level. What is more, contextual effects can already be observed at the level of quantum physics, where higher levels can modify the nature of lower-level elements by changing their context, or even creating them. (...) As one moves up through higher levels, contextual effects on lower levels occur on various scales within nature, which is crucial in biology in general and the brain in particular. We then argue that there are important logical downward causes.objects have causal effects on material-energetic systems. It can be shown that abstract objects have measurable effects on lower levels, which needs to be accounted for by successful explanations of real phenomena such as intentional action. Intentional action has the form of deductive causation from logical structures to human agency. Without this assumption, we would not be warranted in believing that our physical theories latch onto a universe that is essentially the way we discover it to be. Denying top-down causation on account of the idea that the universe permits only bottom-up constitution of wholes from lower-level elements leads to undermining the very possibility of knowledge and science. Thus, it can be rejected as a global form of explanation. We sketch a model for mind-body interaction according to which the various levels of a human organism together enable the emergence of mental top-down effects. They are necessary conditions for the emergence of human mindedness. Once it is clear that downward causation is a widespread natural phenomenon, the apparent mystery of mental causation is, in principle, solved. (shrink)

ABSTRACT Academic dishonesty has remained high in Chinese college students. We examined Chinese college senior students’ everyday academic practices, especially academic dishonesty, considering the contextual changes inside and outside higher learning settings in China. Data were collected from 120 college seniors from four universities and were analyzed using a qualitative content-based exploratory approach in NVivo 10. Three themes were identified, including college seniors’ perceptions of academic dishonesty, contextual influences on academic dishonesty, and seniors’ personal attitudes about academic misconduct. Interview results (...) indicated that the contextual changes have reduced cheating both at the national level and at the college level; however, some contextual factors stubbornly remain unchanged, suggesting that the current, contextual climate on and beyond the Chinese college campuses should be restructured, not necessarily exclusively using top-down approaches. A theoretical model was provided to illustrate mechanisms associated with these students’ academic misconduct. Suggestions are discussed regarding future research and implications made for university personnel practice. (shrink)

This commentary challenges the authors to use their computational modeling techniques to support one of their central claims: that schizophrenic deficits in bottom-up (Gestalt-type tasks) and top-down (cognitive control tasks) context processing tasks arise from the same dysfunction. Further clarification about the limits of cognitive coordination would also strengthen the hypothesis.

Though predictive processing approaches to the mind were originally applied to exteroceptive perception, i.e., vision and action, recent work has started to explore the role of interoceptive perception, i.e., emotion and affect. This article builds on this work by extending PP beyond emotion to the construction of emotional dispositions. I employ principles from dynamical systems theory and PP to provide a model of how dispositional anger can develop in response to early experiences of psychosocial stress. The model is then deployed (...) to explain the established link between psychosocial stress in early life and the appearance of certain organic disease phenotypes in later life. This phenomenon can appear mysterious when viewed through the standard biomedical explanatory lens, which has difficulty accounting for the causal influence of subjective perceptions and evaluations of the social and material environment on the development of organic disease processes. The model provided presents such cases as instances of developmental mismatch. They occur when an organism develops an emotional disposition that leads them to make habitually-biased appraisals of what the social environment affords. The model provides a novel explanation of certain organic disease phenotypes with top-down and developmental causes, and demystifies one class of cases involving apparently spooky ‘mind-to-matter’ causation.

Previous findings in cultural psychology indicated that East Asians are more likely than North Americans to be attentive to contextual information (e.g., Nisbett & Masuda, ). However, to what extent and in which conditions culture influences patterns of attention has not been fully examined. As a result, universal patterns of attention may be obscured, and culturally unique patterns may be wrongly assumed to be constant across situations. By carrying out two cross-cultural studies, we demonstrated that (a) both European Canadians and (...) Japanese attended to moving objects similarly when the task was to simply observe the visual information; however, (b) there were cultural variations in patterns of attention when participants actively engaged in the task by constructing narratives of their observation (narrative construction). These findings suggest that cultural effects are most pronounced in narrative construction conditions, where the need to act in accordance with a culturally shared meaning system is elicited.

Mechanisms to engage lay citizens in science and technology are currently in vogue worldwide. While some engagement exercises aim to influence policy making, research suggests that they have had little discernable impacts in this regard. We explore the potentials and challenges of facilitating citizen engagement in nanotechnology from the “topdown,” addressing the following questions: Can academics and others within institutions initiate meaningful engagement with unorganized lay citizens from the top-down? Can they facilitate effective engagement among citizens, scientists, and policy (...) makers while building citizen engagement capacities? Is it possible to create independent bottom-up citizen engagement in scientific and technological issues from the top-down, and what are the challenges in doing so? Our experiences show that although academics can build citizens' individual, collective, and political capacities to engage with each other, scientists, and policy makers, this work is enormously time and energy intensive, and institutional support is needed to sustain it.

This article has as its objective to analyze the relationship between the human decision making processes and self-regulating capacity / in the development of top-down regulation, in this particular case, by means of contemplative practices, principally mindfulness meditation. This debate is supported upon the nexus established between the cognitive and emotional processes, searching for comprehension of the casual bases of human decision making and the cognitive and affective process. From this theoretical perspective, emotions exercise the role of prominent neurobiological mechanisms (...) in the decision-making process, thus revoking very influential rationalist and dualist Cartesian logic that have held sway until the present day. Through such characteristics, the dichotomous perspective between emotional and cognitive processes loses impact and augmentative influence, whereas the collaborative and integrative role between these two mechanisms that regulate the decision making behavior of individuals is reinforced. The theoretical foundation that supports the approach defended in this study is sustained upon neurophenomenology, which interacts synergistically with phenomenological approaches, modern discoveries from neuroscience and the oriental contemplative practices. In another sense, the interdisciplinarity between philosophy and the practical sciences provides the means for a conceptual proposal that produces a consistent dialogue with that of experimental, cognitive and neural discoveries. Thus producing the groundwork for a meaningful analysis of neurobiological and philosophical hypotheses of the classic problems related to our capacity for self-determination, self-government and voluntary control over our actions. In summary, through an examination of the current situation, few academic discussions propose such a broad and interdisciplinary debate on this theme, thus falling time and time again upon old conceptual paradigms, which are today already noticeably outweighed by empirical findings of the mind. Therefore, by incorporating into the philosophical debate cognition, millenary practices and scientific experience, we will produce a short theoretical conceptual revision concerning decision making until our arrival at the modern experiments performed with experienced meditators. Through this journey we will propose a philosophical discussion that presents new academic perspectives congruent with the debates on modern decision making and our capacity to self-regulate.

The olfactory system was traditionally thought to lack a thalamic relay to mediate top-down influences from memory and attention in other perceptual modalities. Olfactory perception was therefore often described as an outlier among perceptual modalities. It was argued as a result that olfaction was a canonical example of a direct perception. In this paper we review functional and anatomical evidence which demonstrates that olfaction depends on both direct pathway connecting anterior piriform cortex to orbitofrontal cortex and an indirect thalamic circuit (...) connecting posterior piriform cortex and orbitofrontal cortices to the olfactory system. We argue that the indirect corticothalamic circuit has the structure to potentially mediate mediates top-down influences of memory and attention in olfactory perception. This suggests that olfaction is not an outlier after all. (shrink)

Biologists have long known that animal population dynamics are regulated by a combination of bottom-up and top-down forces. Yet, economists have argued that human population dynamics can also be influenced by intraspecific cooperation. Despite awareness of the role of interspecific cooperation in influencing resource availability and animal population dynamics, the role of intraspecific cooperation under different environmental conditions has rarely been considered. Here we examine the role of what we call “lateral forces” that act within populations and interact with external (...) top-down and bottom-up forces in influencing population dynamics using an individual-based model linking environmental quality, intraspecific cooperation, and population size. We find that the proportion of cooperators is higher when the environment is poor and population sizes are greatest under intermediate resources levels due to the contrasting effects of resource availability on behavior and population size. We also show that social populations are more resilient to environmental change than non-social ones because the benefits of intraspecific cooperation can outweigh the effects of constrained resource availability. Our study elucidates the complex relationship between environmental harshness, cooperation, and population dynamics, which is important for understanding the ecological consequences of cooperation.

This experiment investigated the effect of format (line vs. bar), viewers’ familiarity with variables, and viewers’ graphicacy (graphical literacy) skills on the comprehension of multivariate (three variable) data presented in graphs. Fifty-five undergraduates provided written descriptions of data for a set of 14 line or bar graphs, half of which depicted variables familiar to the population and half of which depicted variables unfamiliar to the population. Participants then took a test of graphicacy skills. As predicted, the format influenced viewers’ interpretations (...) of data. Specifically, viewers were more likely to describe x–y interactions when viewing line graphs than when viewing bar graphs, and they were more likely to describe main effects and “z–y” (the variable in the legend) interactions when viewing bar graphs than when viewing line graphs. Familiarity of data presented and individuals’ graphicacy skills interacted with the influence of graph format. Specifically, viewers were most likely to generate inferences only when they had high graphicacy skills, the data were familiar and thus the information inferred was expected, and the format supported those inferences. Implications for multivariate data display are discussed. (shrink)

Our understanding of body ownership largely relies on the Rubber Hand Illusion (RHI) paradigm where synchronous stroking of the real and fake hands leads to an illusion of ownership of RH provided its physical, anatomical, and spatial plausibility. Self-attribution of a fake hand also occurs during visuomotor synchrony, when the visual feedback of self-initiated movements follows the trajectory of the instantiated motor command. In both cases, the experience of ownership is established through bottom-up integration and top-down prediction of multisensory (proximodistal) (...) cues within the peripersonal space. It seems, however, that depending on whether the signals are externally or self-generated, top-down expectation signals are qualitatively different. On the one hand, in RHI, the sensory correlations are modulated by empirically induced priors about the internal model of the body. On the other hand, in mRHI, body ownership is actively shaped by processes allowing for continuous comparison between the actual and predicted sensory consequences of the actions. Ample research demonstrates that the differential processing of the predicted and the actual reafferent information is addressed by the central nervous system via an internal Forward Model (FM). Indeed, results from mRHI suggest that in action-contexts mechanism underlying body ownership could be similar to the FM. Crucially FMs integrate across all sensory input including not only proximodistal (visuomotor) but also purely distal sensory signals (visuoauditory). Thus if body ownership results from a consistency of FM, it would be affected by the (in)congruency of purely distal signals provided that they inform about the action-consequences relevant to the task. Here we explicitly address this question. To test our hypothesis, we devise an embodied VR-based task where action outcomes were signaled by distinct auditory cues. By manipulating the cues with respect to their spatial, temporal and semantic congruency, we show that purely distal feedback violating predictions about action outcomes compromises both body ownership and performance. These results demonstrate that body ownership is influenced by cues which not only pertain to the body itself but also those arising outside of the body, and suggest that in goal-oriented tasks body ownership might result from the consistency of forward models.

In everyday life, people typically observe fragments of causal networks. From this knowledge, people infer how novel combinations of causes they may never have observed together might behave. I report on 4 experiments that address the question of how people intuitively integrate multiple causes to predict a continuously varying effect. Most theories of causal induction in psychology and statistics assume a bias toward linearity and additivity. In contrast, these experiments show that people are sensitive to cues biasing various integration rules. (...) Causes that refer to intensive quantities (e.g., taste) or to preferences (e.g., liking) bias people toward averaging the causal influences, whereas extensive quantities (e.g., strength of a drug) lead to a tendency to add. However, the knowledge underlying these processes is fallible and unstable. Therefore, people are easily influenced by additional task‐related context factors. These additional factors include the way data are presented, the difficulty of the inference task, and transfer from previous tasks. The results of the experiments provide evidence for causal model and related theories, which postulate that domain‐general representations of causal knowledge are influenced by abstract domain knowledge, data‐driven task factors, and processing difficulty.

This contribution investigates the role ofcontext in natural-language communication bydifferentiating between linguistic andsociocultural contexts. It is firmly anchoredto a dialogue framework and based on arelational conception of context as astructured and interactionally organisedphenomenon. However, context is not onlyexamined from this bottom-up or microperspective, but also from a top-down or macroviewpoint as pre- and co-supposed socioculturalcontext. Here, context is not solely seen as aninteractionally organised phenomenon, butrather as a sociocultural apparatus whichstrongly influences the interpretation of microsituations.The section, micro (...) building blocks andlocal meaning, argues for a sociopragmaticapproach to natural-language communication thusaccommodating both speech act theory andconversation analysis.

The definition ofa plus/minus-validity claim is furthersupplemented by the Gricean CooperativePrinciple, the ethnomethodological premise ofaccountability of social action, theconversation-analytic notion of sequentialorganisation and the interpersonal concepts offace and participation format. Validity claimsare discussed from both bottom-up and top-downperspectives stressing the dynamics of contextwith regard to both process and product, andselection and construction. (shrink)

Much debate about scientific realism concerns the issue of whether it is compatible with theory change over time. Certain forms of ‘selective realism’ have been suggested with this in mind. Here I consider a closely related challenge for realism: that of articulating how a theory should be interpreted at any given time. In a crucial respect the challenges posed by diachronic and synchronic interpretation are the same; in both cases, realists face an apparent dilemma. The thinner their interpretations, the easier (...) realism is to defend, but at the cost of more substantial commitment. The more substantial their interpretations, the more difficult they are to defend. I consider this worry in the context of the Standard Model of particle physics. Examining some selective realist attempts at interpretation, I argue that realism is, in fact, compatible with different commitments on the spectrum of thinner to more substantial, thus mitigating the dilemma.

While top-down descriptors have received much attention in explaining corruption, we develop a grassroots model to describe structural factors that may influence the emergence and spread of an individual’s (un)ethical behavior within organizations.

We discuss and develop an individual-level theory of planned behavior, then extend it to (...) the dyadic level in an internally competitive organization, and finally extend the dyadic model to the social network. We apply social network theory to predict favorable and unfavorable conditions for the emergence and diffusion of an intraorganizational instance of unethical behavior and find that network conditions favoring the suppression of the emergence of unethical behavior also promote its diffusion. For illustrative purposes, we utilize examples from Enron’s internally competitive structure to embed our arguments in a real world context and bring reality to our theorizing. Implications for both researchers and managers are discussed. (shrink)

A long-standing question in cognitive science is how high-level knowledge is integrated with sensory input. For example, listeners can leverage lexical knowledge to interpret an ambiguous speech sound, but do such effects reflect direct top-down influences on perception or merely postperceptual biases? A critical test case in the domain of spoken word recognition is lexically mediated compensation for coarticulation (LCfC). Previous LCfC studies have shown that a lexically restored context phoneme (e.g., /s/ in Christma#) can alter the perceived place (...) of articulation of a subsequent target phoneme (e.g., the initial phoneme of a stimulus from a tapes-capes continuum), consistent with the influence of an unambiguous context phoneme in the same position. Because this phoneme-to-phoneme compensation for coarticulation is considered sublexical, scientists agree that evidence for LCfC would constitute strong support for top–down interaction. However, results from previous LCfC studies have been inconsistent, and positive effects have often been small. Here, we conducted extensive piloting of stimuli prior to testing for LCfC. Specifically, we ensured that context items elicited robust phoneme restoration (e.g., that the final phoneme of Christma# was reliably identified as /s/) and that unambiguous context-final segments (e.g., a clear /s/ at the end of Christmas) drove reliable compensation for coarticulation for a subsequent target phoneme. We observed robust LCfC in a well-powered, preregistered experiment with these pretested items (N = 40) as well as in a direct replication study (N = 40). These results provide strong evidence in favor of computational models of spoken word recognition that include top–down feedback. (shrink)

Analyses of participation usually assume a dichotomy between 'instrumental' and 'transformative' approaches. However, this study of voluntary biological monitoring experiences and outcomes finds that they cannot be fitted into such a dichotomy. They can enhance the information base for environmental management; change participants through education about scientific practice and ecological change; lead to changes in life direction or group organisation; and influence decision-makers. Personal transformation can take place within a conventionally top-down context. Conversely, grassroots data collection can shore (...) up the status quo and protect local interests. Partnerships between actors can provide distinct but complementary and mutually rewarding outcomes. Power is not located in a data-consuming centre, and data are not meaningless materials that leave the collector unmoved. A more dynamic model of human-nature relations is presented which connects humans and information in the participatory process. (shrink)

Philosophy for Children (P4C) provides educators with the process and structures to engage children in inquiring as a group into 'big' moral, ethical, and spiritual questions, while also considering curricular necessities and the demands of national and local standards. Based on the actual experiences of educators in diverse and global classroom contexts, this comprehensive guide gives you the tools you need to introduce philosophical thinking into your classroom, curriculum and beyond. Drawing on research-based educational and psychological models, this book highlights (...) the advantages gained by students who regularly participate in philosophical discussion: from building cognitive and social/emotional development, to becoming more informed citizens. Helpful tools and supplementary online resources offer additional frameworks for supporting and sustaining a higher level of thinking and problem-solving among your students. This practical guide is essential reading for teachers, coaches, and anyone wondering how you can effectively teach philosophy in your classroom. (shrink)
