While the subjective experience of insight during problem solving is a common occurrence, an understanding of the processes leading to solution remains relatively uncertain. The goal of this study was to investigate the restructuring patterns underlying solution of a creative problem, and how providing cues to solution may alter the process. Results show that both providing cues to solution and analyzing problem solving performance on an aggregate level may result in restructuring patterns that appear incremental. Analysis of performance on an (...) individual level provides evidence for insight-like solution patterns. However, no evidence is found for a relationship between an individual’s restructuring pattern and their subjective experience of insight during problem solving. (shrink)

Alcohol use has long been assumed to alter cognition via attentional processes. To better understand the cognitive consequences of intoxication, the present study tested the effects of moderate intoxication on attentional processing using complex working memory capacity span tasks and a change blindness task. Intoxicated and sober participants were matched on baseline WMC performance, and intoxication significantly decreased performance on the complex span tasks. Surprisingly, intoxication improved performance on the change blindness task. The results are interpreted as evidence that intoxication (...) decreases attentional control, causing either a shift towards more passive processing and/or a more diffuse attentional state. This may result in decreased performance on tasks where attentional control or focus are required, but may actually facilitate performance in some contexts. (shrink)

That alcohol provides a benefit to creative processes has long been assumed by popular culture, but to date has not been tested. The current experiment tested the effects of moderate alcohol intoxication on a common creative problem solving task, the Remote Associates Test . Individuals were brought to a blood alcohol content of approximately .075, and, after reaching peak intoxication, completed a battery of RAT items. Intoxicated individuals solved more RAT items, in less time, and were more likely to perceive (...) their solutions as the result of a sudden insight. Results are interpreted from an attentional control perspective. (shrink)

This paper is concerned with the processing of informal arguments, that is, arguments involving “probable truth.” A model of informal argument processing is presented that is based upon Hample's (1977) expansion of Toulmin's (1958) model of argument structure. The model postulates that a claim activates an attitude, the two components forming a complex that in turn activates reasons. Furthermore, the model holds occurrence of the reason, or possibly the claim and the reason, activates values. Three experiments are described that provide (...) support for the model. (shrink)

A novel experimental paradigm that measured theory change and confidence in participants' theories was used in three experiments to test the effects of anomalous evidence. Experiment 1 varied the amount of anomalous evidence to see if “dose size” made incremental changes in confidence toward theory change. Experiment 2 varied whether anomalous evidence was convergent or replicating. Experiment 3 varied whether participants were provided with an alternative theory that explained the anomalous evidence. All experiments showed that participants' confidence changes were commensurate (...) with the amount of anomalous evidence presented, and that larger decreases in confidence predicted theory changes. Convergent evidence and the presentation of an alternative theory led to larger confidence change. Convergent evidence also caused more theory changes. Even when people do not change theories, factors pertinent to the evidence and alternative theories decrease their confidence in their current theory and move them incrementally closer to theory change.

The peptide hormone oxytocin plays a critical role in regulating affiliative behaviors including mating, pair‐bond formation, maternal/parenting behavior, social recognition, separation distress and other aspects of attachment. Jin and colleagues1 recently reported intriguing findings that CD38, a transmembrane receptor with ADP‐ribosyl cyclase activity, plays a critical role in maternal nurturing behavior and social recognition by regulating oxytocin secretion. This research may have implications for understanding disorders marked by deficits in social cognition and social functioning, including autism, social anxiety disorder, borderline (...) personality disorder and schizophrenia.

Aphids display an abundance of adaptations that are not easily studied in existing model systems. Here we review the biology of a new genomic model system, the pea aphid, Acyrthosiphon pisum. We then discuss several phenomena that are particularly accessible to study in the pea aphid: the developmental genetic basis of polyphenisms, aphid–bacterial symbioses, the genetics of adaptation and mechanisms of virus transmission. The pea aphid can be maintained in the laboratory and natural populations can be studied in the field. (...) These properties allow controlled experiments to be performed on problems of direct relevance to natural aphid populations. Combined with new genomic approaches, the pea aphid is poised to become an important model system for understanding the molecular and developmental basis of many ecologically and evolutionarily relevant problems.

There is growing interest in the evolutionary dynamics of molecular genetic pathways and networks, and the extent to which the molecular evolution of a gene depends on its position within a pathway or network, as well as over‐all network topology. Investigations on the relationships between network organization, topological architecture and evolutionary dynamics provide intriguing hints as to how networks evolve. Recent studies also suggest that genetic pathway and network structures may influence the action of evolutionary forces, and may play a (...) role in maintaining phenotypic robustness in organisms.

A unique feature of flowering plants is their ability to produce organs continuously, for hundreds of years in some species, from actively growing tips called apical meristems. All plants possess at least one form of apical meristem, whose cells are functionally analogous to animal stem cells because they can generate specialized organs and tissues. The shoot apical meristem of angiosperm plants acts as a continuous source of pluripotent stem cells, whose descendents become incorporated into organ primordia and acquire different fates. (...) Recent studies are unveiling some of the molecular pathways that specify stem cell fate in the center of the shoot apical meristem, that confer organ founder cell fate on the periphery, and that connect meristem patterning elements with events at the cellular level. The results are providing important insights into the mechanisms through which shoot apical meristems integrate cell fate decisions with cellular proliferation and global regulation of growth and development.

Growth factor receptor tyrosine kinases (RTKs), such as the fibroblast growth factor receptor (FGFR), play a major role in how cells communicate with their environment. FGFR signaling is crucial for normal development, and its misregulation in humans has been linked to developmental abnormalities and cancer. The precise molecular mechanisms by which FGFRs transduce extracellular signals to effect specific biologic responses is an area of intense research. Genetic analyses in model organisms have played a central role in our evolving understanding of (...) these signal transduction cascades. Genetic studies in the nematode C. elegans have contributed to our knowledge of FGFR signaling by identifying genes involved in FGFR signal transduction and linking their gene products together into signaling modules. This review will describe FGFR-mediated signal transduction in C. elegans and focus on how these studies have contributed to our understanding of how FGFRs orchestrate the assembly of intracellular signaling pathways.

In this paper, I discuss the relationship between bodily experiences in dreams and the sleeping, physical body. I question the popular view that dreaming is a naturally and frequently occurring real-world example of cranial envatment. This view states that dreams are functionally disembodied states: in a majority of dreams, phenomenal experience, including the phenomenology of embodied selfhood, unfolds completely independently of external and peripheral stimuli and outward movement. I advance an alternative and more empirically plausible view of dreams as weakly (...) phenomenally-functionally embodied states. The view predicts that bodily experiences in dreams can be placed on a continuum with bodily illusions in wakefulness. It also acknowledges that there is a high degree of variation across dreams and different sleep stages in the degree of causal coupling between dream imagery, sensory input, and outward motor activity. Furthermore, I use the example of movement sensations in dreams and their relation to outward muscular activity to develop a predictive processing account. I propose that movement sensations in dreams are associated with a basic and developmentally early kind of bodily self-sampling. This account, which affords a central role to active inference, can then be broadened to explain other aspects of self- and world-simulation in dreams. Dreams are world-simulations centered on the self, and important aspects of both self- and world-simulation in dreams are closely linked to bodily self-sampling, including muscular activity, illusory own-body perception, and vestibular orienting in sleep. This is consistent with cognitive accounts of dream generation, in which long-term beliefs and expectations, as well as waking concerns and memories play an important role. What I add to this picture is an emphasis on the real-body basis of dream imagery. This offers a novel perspective on the formation of dream imagery and suggests new lines of research. (shrink)

Abstract: Recent experimental research on the 'Knobe effect' suggests, somewhat surprisingly, that there is a bi-directional relation between attributions of intentional action and evaluative considerations. We defend a novel account of this phenomenon that exploits two factors: (i) an intuitive asymmetry in judgments of responsibility (e.g. praise/blame) and (ii) the fact that intentionality commonly connects the evaluative status of actions to the responsibility of actors. We present the results of several new studies that provide empirical evidence in support of this (...) account while disconfirming various currently prominent alternative accounts. We end by discussing some implications of this account for folk psychology. (shrink)

The new field of experimental philosophy has emerged as the methods of psychological science have been brought to bear on traditional philosophical issues. Oxford Studies in Experimental Philosophy will be the place to go to see outstanding new work in the field. It will feature papers by philosophers, papers by psychologists, and papers co-authored by people in both disciplines. The series heralds the emergence of a truly interdisciplinary field in which people from different disciplines are working together to address a (...) shared set of questions. The inaugural volume is roughly structured into four sections. The first three papers focus on recent developments in moral psychology, a topic that has seen lively debate and a great deal of progress over the last decade. The second section highlights three contributions that bring new methods to moral psychology: formal modeling and special populations. The third section brings together four papers that adopt an experimental philosophy approach to novel topics, including intuitive dualism, generics, joint action, and happiness. And the last two papers provide critical and historical context to the development of experimental philosophy. (shrink)

The Character Gap by Christian Miller is an excellent discussion of how the empirical research conducted on virtue bears upon the larger question of whether or not people are virtuous, especially when we consider the question through the lens of a philosophically rigorous account of virtue. His conclusion is that overall people are not virtuous—but then, neither are they vicious. In this commentary, I challenge the latter. I explore two alternative ways of conceiving of vice and utilize a range of (...) empirical findings—on topics ranging from bullying, to sexual assault, to factory farming—to argue that perhaps vice is much more prevalent than Miller believes, a worry that deserves our attention and concern.

This is a comprehensive resource of original essays by leading thinkers exploring the newly emerging inter-disciplinary field of the philosophy of psychiatry. The contributors aim to define this exciting field and to highlight the philosophical assumptions and issues that underlie psychiatric theory and practice, the category of mental disorder, and rationales for its social, clinical and legal treatment. As a branch of medicine and a healing practice, psychiatry relies on presuppositions that are deeply and unavoidably philosophical. Conceptions of rationality, personhood (...) and autonomy frame our understanding and treatment of mental disorder. Philosophical questions of evidence, reality, truth, science, and values give meaning to each of the social institutions and practices concerned with mental health care. The psyche, the mind and its relation to the body, subjectivity and consciousness, personal identity and character, thought, will, memory, and emotions are equally the stuff of traditional philosophical inquiry and of the psychiatric enterprise. A new research field--the philosophy of psychiatry--began to form during the last two decades of the twentieth century. Prompted by a growing recognition that philosophical ideas underlie many aspects of clinical practice, psychiatric theorizing and research, mental health policy, and the economics and politics of mental health care, academic philosophers, practitioners, and philosophically trained psychiatrists have begun a series of vital, cross-disciplinary exchanges. This volume provides a sampling of the research yield of those exchanges. Leading thinkers in this area, including clinicians, philosophers, psychologists, and interdisciplinary teams, provide original discussions that are not only expository and critical, but also a reflection of their authors' distinctive and often powerful and imaginative viewpoints and theories. All the discussions break new theoretical ground. As befits such an interdisciplinary effort, they are methodologically eclectic, and varied and divergent in their assumptions and conclusions; together, they comprise a significant new exploration, definition, and mapping of the philosophical aspects of psychiatric theory and practice.

This discussion is about the moods characteristic of depressive and manic states. Moods are distinguished from the emotions they often accompany, and the relationship between these less and more cognitive, and seemingly less and more intentional, states is provided preliminary clarification. Epistemic deficiencies identified here, when combined with differences of quality and quantity in the moods and motivations that beset the depression and mania sufferer, seem likely to hinder self-knowledge and self-integration. These deficiencies, it is argued, may help explain why (...) the extreme moods found in states of depression and mania contribute to our inclination to regard these conditions as disorder. (shrink)

There is growing interest in the processes by which entrepreneurial opportunities are cocreated between entrepreneurs and their stakeholders. The longitudinal case study of de novo firm Wakefield Seafoods seeks to understand the underlying dynamics of phenomena that play out over time as stakeholders emerge and their contributions become essential to the opportunity formation process. The king crab data show that under conditions of uncertainty, characterized by incomplete or missing knowledge, entrepreneurial processes of experimentation, failure, and learning were effective in forming (...) and exploiting an opportunity. Moreover, contrary to existing literature that either emphasizes heroic entrepreneurs or downplays their value, this article shows that both the vision of the entrepreneur and the stakeholder contributions are critical. This detailed examination of process data shows that the cumulative actions made by entrepreneurs in concert with their stakeholders formed an opportunity that coalesced into a new market. (shrink)

The American Association for the Advancement of Science (AAAS) Dialogue on Science, Ethics, and Religion (DoSER) program has embarked on an exciting project, “Scientists and Religious Communities: Investigating Perceptions to Build Understanding.” The project will provide the first quantitative data on the underlying assumptions and concerns that shape national attitudes on science. A nationally representative survey conducted in collaboration with sociologists at Rice University has reached 10,000 people, including evangelical Christians, mainline Protestants, Catholics, and Jews. The survey probed how a (...) broad range of religious people, particularly evangelical Christians, understands and thinks about science, and what they perceive about scientists. Scientists, broadly defined, were likewise surveyed to gauge their perceptions of how religious people regard science. The goal for AAAS is to increase understanding between the scientific and evangelical Christian communities and redefine this critical relationship. DoSER will bring together leaders from scientific and evangelical communities to discuss the implications of survey results and to use them for building better understanding and communication strategies. Building relationships between scientists and religious communities has the potential to create a new paradigm of understanding. Finding out what each group actually thinks, through a survey, is only the beginning. (shrink)

The Russian invasion of Ukraine in 2022 was met with condemnation from the European Union and the United States as an "unprovoked and unjustified military aggression" that undermines the liberal international order. However, some international relations scholars, such as John Mearsheimer, argue that Russia had genuine security concerns with regard to Ukraine and that the invasion was a response to the threat of NATO membership for Ukraine. Both liberal and realist perspectives on the invasion rely on the assumption of rational, (...) cost-benefit calculations by actors, but cultural factors and irreconcilable non-material interests may also be at play in shaping the actions and motivations of states. Understanding the cultural and national identity factors at play in the invasion of Ukraine is complex and difficult, but they cannot be ignored in attempting to understand and address the conflict.

In this paper, I explore the implications of adopting one model of self rather than another in respect to one particular feature of our mental life. The need to explain synchronic unity in normal subjectivity, and also to explain the apparent and puzzling absence of synchronic unity in certain symptoms of severe mental disorder, I show, becomes more pressing with one particular model. But in the process of developing that explanation we learn something about subjectivity and perhaps also something about (...) brain functioning. (shrink)

It is well established that language production and comprehension are influenced by information status, for example, whether information is given, new, topical, or predictable, and many scholars suggest that an important component of information status is keeping track of what information is in common ground, and what is not. Information status affects both speakers' choices and how listeners interpret the speaker's meaning. Although there is a wealth of scholarly work on information status, there is no consensus on the mechanisms by (...) which it is used, and in fact relatively little discussion of the underlying representations and psycholinguistic mechanisms. Moreover, a major challenge to understanding information status is that its effects are notoriously variable. This study considers existing proposals about information status, focusing on two questions: how is it represented; and by what mechanisms is it used? I propose that it is important to consider whether representations and mechanisms can be classified as either explicit or emergent. Based on a review of existing evidence, I argue that information status representations are most likely emergent, but the mechanisms by which they are used are both explicit and emergent. This review provides one of the first considerations of information status processing across multiple domains. (shrink)

In this paper I argue that reference to a developmental account of agency can help explain, and in cases also alter, our current practices when it comes to the non-consensual medical treatment of children. It does this through its explanation of how stages of development impact the types of interests we have.

In this paper, I write about nurses of colour who have made significant contributions to nursing, yet are actively ignored in traditional nursing textbooks related to colonized thinking. One consequence of this is that when we think about comparing the disparities of the past to the present day, we see that we have not made much of a difference. The disparity is still huge. I call on all of us as nurses to challenge ourselves to think beyond the box of (...) colonized thought to what we know is true. (shrink)
