Drawing on recent findings in the cognitive and neurosciences, this article discusses how people manage to predict each other’s actions, which is fundamental for joint action. We explore how a common coding of perceived and performed actions may allow actors to predict the what, when, and where of others’ actions. The “what” aspect refers to predictions about the kind of action the other will perform and to the intention that drives the action. The “when” aspect is critical for all joint (...) actions requiring close temporal coordination. The “where” aspect is important for the online coordination of actions because actors need to effectively distribute a common space. We argue that although common coding of perceived and performed actions alone is not sufficient to enable one to engage in joint action, it provides a representational platform for integrating the actions of self and other. The final part of the paper considers links between lower‐level processes like action simulation and higher‐level processes like verbal communication and mental state attribution that have previously been at the focus of joint action research.

Based on Pacherie’s dynamic theory of intentions, this study investigated how the way an intention is formed and sustained affects action performance and the experience of control during acting. In Experiment 1, task-irrelevant verbal commands were given while participants responded to stimuli in a two-choice reaction time task. The commands referred to an action goal congruent or incongruent with the actor’s current intention, or ordered the initiation or abortion of the action. In Experiment 2, the same commands were given as (...) participants freely chose between two actions. The distractors affected performance in the reactive task only. In both experiments, feelings of control were based on movement parameters as well as perceived matches between distractors and intended actions. These findings suggest that the way an intention is implemented affects how well it can be shielded against external perturbations and how much one feels in control. (shrink)

Philosophers, psychologists, neuroscientists, and psychiatrists examine the will and its pathologies from theoretical and empirical perspectives, offering a conceptual overview and discussing schizophrenia, depression, prefrontal lobe damage, and substance abuse as disorders of volition. Science tries to understand human action from two perspectives, the cognitive and the volitional. The volitional approach, in contrast to the more dominant "outside-in" studies of cognition, looks at actions from the inside out, examining how actions are formed and informed by internal conditions. In Disorders of (...) Volition, scholars from a range of disciplines seek to advance our understanding of the processes supporting voluntary action by addressing conditions in which the will is impaired. Philosophers, psychologists, neuroscientists, and psychiatrists examine the will and its pathologies from both theoretical and empirical perspectives, offering a conceptual overview and discussing specific neurological and psychiatric conditions as disorders of volition. After presenting different conceptual frameworks that identify agency, decision making, and goal pursuit as central components of volition, the book examines how impairments in these and other aspects of volition manifest themselves in schizophrenia, depression, prefrontal lobe damage, and substance abuse.

This article explores the role of social factors in the emergence of self and other. It is suggested that the experience of causing actions contributes to a basic sense of self in which awareness of mental states and the experience of a mental self are grounded. According to the proposed evolutionary scenario, the experience of agency emerged as individuals acting in social context learned to differentiate between effects caused by their own actions and effects resulting from joint action. Through joint (...) action, individuals also developed an understanding of others' actions as goal-directed, paving the way for imitation. The ability to distinguish between action capabilities of self and other and the understanding that action-effect principles apply equally to self and other may have provided important advantages in circumstances where cooperative action and social learning were critical. The current proposal adds to previous evolutionary scenarios in that it identifies social conditions that may have shaped a basic sense of self. This, in turn, could have given rise to theory of mind and the cultural construction of mental selves. (shrink)

In recent years researchers have begun to investigate how the perceptual, motor and cognitive activities of two or more individuals become organized into coordinated action. In the first part of this introduction we identify three common threads among the ten papers of this special issue that exemplify this new line of research. First, all of the papers are grounded in the experimental study of online interactions between two or more individuals. Second, albeit at different levels of analysis, the contributions focus (...) on the mechanisms supporting joint action. Third, many of the papers investigate empirically the pre‐requisites for the highly sophisticated forms of joint action that are typical of humans. In the second part of the introduction, we summarize each of the papers, highlighting more specific connections among them. (shrink)

Successful communication is important for both society and people’s personal life. Here we show that people can improve their communication skills by interacting with multiple others, and that this improvement seems to come about by a greater tendency to take the addressee’s perspective when there are multiple partners. In Experiment 1, during a training phase, participants described figures to a new partner in each round or to the same partner in all rounds. Then all participants interacted with a new partner (...) and their recordings from that round were presented to naïve listeners. Participants who had interacted with multiple partners during training were better understood. This occurred despite the fact that the partners had not provided the participants with any input other than feedback on comprehension during the interaction. In Experiment 2, participants were asked to provide descriptions to a different future participant in each round or to the same future participant in all rounds. Next they performed a surprise memory test designed to tap memory for global details, in line with the addressee’s perspective. Those who had provided descriptions for multiple future participants performed better. These results indicate that people can improve their communication skills by interacting with multiple people, and that this advantage might be due to a greater tendency to take the addressee’s perspective in such cases. Our findings thus show how the social environment can influence our communication skills by shaping our own behavior during interaction in a manner that promotes the development of our communication skills.

Imitation research has focused on turn‐taking contexts in which one person acts and one person then copies that action. However, people also imitate when engaging in joint actions, where two or more people coordinate their actions in space and time in order to achieve a shared goal. We discuss how the various constraints imposed by joint action modulate imitation, and the close links between perception and action that form the basis of this phenomenon. We also explore how understanding imitation in (...) the context of joint action yields new insights into cultural phenomena such as teaching and innovation. (shrink)

In the absence of pre‐established communicative conventions, people create novel communication systems to successfully coordinate their actions toward a joint goal. In this study, we address two types of such novel communication systems: sensorimotor communication, where the kinematics of instrumental actions are systematically modulated, versus symbolic communication. We ask which of the two systems co‐actors preferentially create when aiming to communicate about hidden object properties such as weight. The results of three experiments consistently show that actors who knew the weight (...) of an object transmitted this weight information to their uninformed co‐actors by systematically modulating their instrumental actions, grasping objects of particular weights at particular heights. This preference for sensorimotor communication was reduced in a fourth experiment where co‐actors could communicate with weight‐related symbols. Our findings demonstrate that the use of sensorimotor communication extends beyond the communication of spatial locations to non‐spatial, hidden object properties. (shrink)

When two or more people coordinate their actions in space and time to produce a joint outcome, they perform a joint action. The perceptual, cognitive, and motor processes that enable individuals to coordinate their actions with others have been receiving increasing attention during the last decade, complementing earlier work on shared intentionality and discourse. This chapter reviews current theoretical concepts and empirical findings in order to provide a structured overview of the state of the art in joint action research. We (...) distinguish between planned and emergent coordination. In planned coordination, agents' behavior is driven by representations that specify the desired outcomes of joint action and the agent's own part in achieving these outcomes. In emergent coordination, coordinated behavior occurs due to perception action couplings that make multiple individuals act in similar ways, independently of joint plans. We review evidence for the two types of coordination and discuss potential synergies between them. (shrink)

We suggest that certain experiences reported by patients with schizophrenia show that priority, consistency, and exclusivity are not sufficient for the experience of willing an action. Furthermore, we argue that even if priority, consistency, and exclusivity cause the experience of being the author of an action, this does not mean that conscious will is an illusion.

The sense of agency has received much attention in the context of individual action but not in the context of joint action. We investigated how the sense of agency developed during individual and dyadic performance while people learned a haptic coordination task. The sense of agency increased with better performance in all groups. Individuals and dyads showed a differential sense of agency after initial task learning, with dyads showing a minimal increase. The sense of agency depended on the context in (...) which the task was first learnt, as transfer from joint to individual performance resulted in an illusory boost in the sense of agency. Whereas the quality of performance related to the sense of agency, the generated forces to achieve the task did not. Our findings are consistent with a predictive model account at the perceptual level, such that the sense of agency relies most strongly on sharable perceptual information. (shrink)

Summary: This volume is interesting and worth reading as an introduction to the philosophical and cognitive neuroscience research on volition.

This book presents a radical and intuitive argument against the notion that intentional action, agency and autonomy are features belonging only to humans. Using evidence from research into the minds of non-human animals, it explores the ways in which animals can be understood as individuals who are aware of themselves, and the consequent basis of our moral obligations towards them. The first part of this book argues for a conception of agency in animals that admits to degrees among individuals and (...) across species. It explores self-awareness and its various levels of complexity which depend on an animals’ other mental capacities. The author offers an overview of some established theories in animal ethics including those of Peter Singer, Tom Regan, Bernard Rollin and Lori Gruen, and the ways these theories serve to extend moral consideration towards animals based on various capacities that both animals and humans have in common. The book concludes by challenging traditional Kantian notions of rationality and what it means to be an autonomous individual, and discussing the problems that still remain in the study of animal ethics.

Background:Moral distress is a complex phenomenon frequently experienced by critical care nurses. Ethical conflicts in this practice area are related to technological advancement, high intensity work environments, and end-of-life decisions.Objectives:An exploration of contemporary moral distress literature was undertaken to determine measurement, contributing factors, impact, and interventions.Review Methods:This state of the science review focused on moral distress research in critical care nursing from 2009 to 2015, and included 12 qualitative, 24 quantitative, and 6 mixed methods studies.Results:Synthesis of the scientific literature revealed (...) inconsistencies in measurement, conflicting findings of moral distress and nurse demographics, problems with the professional practice environment, difficulties with communication during end-of-life decisions, compromised nursing care as a consequence of moral distress, and few effective interventions.Conclusion:Providing compassionate care is a professional nursing value and an inability to meet this goal due to moral distress may have devastating effects on care quality. Further study of patient and family outcomes related to nurse moral distress is recommended. (shrink)

Trolley problems have been used in the development of moral theory and the psychological study of moral judgments and behavior. Most of this research has focused on people from the West, with implicit assumptions that moral intuitions should generalize and that moral psychology is universal. However, cultural differences may be associated with differences in moral judgments and behavior. We operationalized a trolley problem in the laboratory, with economic incentives and real-life consequences, and compared British and Chinese samples on moral behavior (...) and judgment. We found that Chinese participants were less willing to sacrifice one person to save five others, and less likely to consider such an action to be right. In a second study using three scenarios, including the standard scenario where lives are threatened by an on-coming train, fewer Chinese than British participants were willing to take action and sacrifice one to save five, and this cultural difference was more pronounced when the consequences were less severe than death.

In this paper I explore the relationship between social epistemology and relativism in the context of feminist epistemology. I do this by focusing on one particular branch of feminist epistemology - a branch known as standpoint theory - and investigating the connection between this view and epistemic relativism. I begin by defining both epistemic relativism and standpoint theory, and by briefly recounting the standard way that the connection between these two views is understood. The literature at the moment focuses on (...) an aspect of standpoint theory called the epistemic advantage thesis, and on an aspect of relativism which has been called equality. I then show that the connection between relativism and standpoint theory actually turns on a different aspect of standpoint theory, known as the standpoint thesis, and on an aspect of relativism which has been called non-neutrality. I argue that shifting our attention to these other aspects reveals that standpoint theory is clearly and unavoidably relativist, but that this isn’t a problem - standpoint theory can capture everything that it set out to, even on a relativist understanding of the view.

The diagnostic category of borderline personality disorder (BPD) has come under increasing criticism in recent years. In this paper, we analyze the role and impact of epistemic injustice, specifically testimonial injustice, in relation to the diagnosis of BPD. We first offer a critical sociological and historical account, detailing and expanding a range of arguments that BPD is problematic nosologically. We then turn to explore the epistemic injustices that can result from a BPD diagnosis, showing how they can lead to experiences (...) of testimonial injustice which impede patient engagement in meaning-making activities, thereby undermining standard therapeutic goals. We conclude by showing how our arguments bolster ongoing efforts to replace the diagnostic category of BPD with alternatives such as complex post-traumatic stress disorder. (shrink)

Homeopathy is over 200 years old and is still experiencing an uninterrupted influx of new practitioners and patients. Many patients and therapists swear by this "alternative healing method", which in some countries is even financed by health insurances. This seems completely incomprehensible to critics: For them it is clearly evident that homeopathy is hopelessly unscientific and has at best a placebo effect. The positions of supporters and opponents seem to be just as immutable as they are incompatible. This book answers (...) some essential and fascinating questions: What remains of the founding ideas of homeopathy in 21st century medicine? Does it really work and, if so, how? Which of the original theories can we still apply today with a clear conscience and use for the benefit of patients and the healthcare system? Where does homeopathy have its limits and does it indeed need to be critically reconsidered and evaluated? The author has dealt with the points of criticism for years, but at the same time also takes seriously the wishes and concerns of patients who often feel insufficiently cared for by conventional medical practice. Against the background of her own personal history, her book attempts to bridge the gap between these two traditionally opposing camps. (shrink)
