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)

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.

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.

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)

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)

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.

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)

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.

Searches for the sources and means for a disciplined practical approach to exploring human experience.

Game theory is central to modern understandings of how people deal with problems of coordination and cooperation. Yet, ironically, it cannot give a straightforward explanation of some of the simplest forms of human coordination and cooperation--most famously, that people can use the apparently arbitrary features of "focal points" to solve coordination problems, and that people sometimes cooperate in "prisoner's dilemmas." Addressing a wide readership of economists, sociologists, psychologists, and philosophers, Michael Bacharach here proposes a revision of game theory that resolves (...) these long-standing problems. In the classical tradition of game theory, Bacharach models human beings as rational actors, but he revises the standard definition of rationality to incorporate two major new ideas. He enlarges the model of a game so that it includes the ways agents describe to themselves their decision problems. And he allows the possibility that people reason as members of groups, each taking herself to have reason to perform her component of the combination of actions that best achieves the group's common goal. Bacharach shows that certain tendencies for individuals to engage in team reasoning are consistent with recent findings in social psychology and evolutionary biology. As the culmination of Bacharach's long-standing program of pathbreaking work on the foundations of game theory, this book has been eagerly awaited. Following Bacharach's premature death, Natalie Gold and Robert Sugden edited the unfinished work and added two substantial chapters that allow the book to be read as a coherent whole. (shrink)
