A sense of agency over wilful actions is thought to be dependent on the level of choice and the nature of the outcome. In a preregistered study, we manipulated choice and valence of outcome to assess the relationship between SoA across the depression and psychosis continuum. Participants completed a Libet Clock task, in which they had either a free or forced choice to press one of two buttons and received either a rewarding or punishing outcome. Participants also completed questionnaires on (...) depressive and psychosis-like traits. Rewarding outcomes increased intentional binding. The evidence favoured no effect of choice on average, but this was influenced by inter-individual differences. Individuals reporting more depressive traits had less of a difference in intentional binding between free and forced choice conditions. We show that implicit SoA is sensitive to outcome valence and the effect of choice differs across the depression continuum. (shrink)

Joint actions typically involve a sense of togetherness that has a distinctive phenomenological component. While it has been hypothesized that group size, hierarchical structure, division of labour, and expertise impact agents’ phenomenology during joint actions, the studies conducted so far have mostly involved dyads performing simple actions. We explore in this study the complex case of collectively improvised musical performances, focusing particularly on the way group size and interactional patterns modulate the phenomenology of joint action. We recorded two expert improvisation (...) ensembles of contrasting sizes and collected data about their musical behaviour, as well as reports about five aspects of their phenomenology and about their musical intentions. Our overall data enabled us to assess how those five phenomenological dimensions related to one another during jointly improvised performances. They also show how such phenomenology varied with the way improvisers dynamically related to one another throughout the performance. Finally, we observe that group size strongly altered the phenomenology of improvisers who otherwise shared many characteristics. Our study thus sheds light on the interactional and structural parameters that shape and modulate our felt experience when acting together, and thereby highlights the importance of pluralism for studying the phenomenology of joint action.

In this article, we suggest that the study of social interactions and the development of a “sense of agency” in joint action can help determine the content of relevant explanations to be implemented in artificial systems to make them “explainable.” The introduction of automated systems, and more broadly of Artificial Intelligence, into many domains has profoundly changed the nature of human activity, as well as the subjective experience that agents have of their own actions and their consequences – an experience (...) that is commonly referred to as sense of agency. We propose to examine the empirical evidence supporting this impact of automation on individuals’ sense of agency, and hence on measures as diverse as operator performance, system explicability and acceptability. Because of some of its key characteristics, AI occupies a special status in the artificial systems landscape. We suggest that this status prompts us to reconsider human–AI interactions in the light of human–human relations. We approach the study of joint actions in human social interactions to deduce what key features are necessary for the development of a reliable sense of agency in a social context and suggest that such framework can help define what constitutes a good explanation. Finally, we propose possible directions to improve human–AI interactions and, in particular, to restore the sense of agency of human operators, improve their confidence in the decisions made by artificial agents, and increase the acceptability of such agents.

Five studies replicate and extend recent experimental findings on a divergence between theoretical and subjectively-experienced decision freedom. While conditions like conflict, uncertainty, or com...

In temporal binding, the temporal interval between one event and another, occurring some time later, is subjectively compressed. We discuss two ways in which temporal binding has been conceptualized. In studies showing temporal binding between a voluntary action and its causal consequences, such binding is typically interpreted as providing a measure of an implicit or pre-reflective “sense of agency”. However, temporal binding has also been observed in contexts not involving voluntary action, but only the passive observation of a cause-effect sequence. (...) In those contexts, it has been interpreted as a top-down effect on perception reflecting a belief in causality. These two views need not be in conflict with one another, if one thinks of them as concerning two separate mechanisms through which temporal binding can occur. In this paper, we explore an alternative possibility: that there is a unitary way of explaining temporal binding both within and outside the context of voluntary action as a top-down effect on perception reflecting a belief in causality. Any such explanation needs to account for ways in which agency, and factors connected with agency, have been shown to affect the strength of temporal binding. We show that principles of causal inference and causal selection already familiar from the literature on causal learning have the potential to explain why the strength of people’s causal beliefs can be affected by the extent to which they are themselves actively involved in bringing about events, thus in turn affecting binding.

Recent findings support the idea that the belief in free will serves as the basis for moral responsibility, thus promoting the punishment of immoral agents. We theorized that free will extends beyond morality to serve as the basis for accountability and the capacity for change more broadly, not only for others but also for the self. Five experiments showed that people attributed higher freedom of will to negative than to positive valence, regardless of morality or intent, for both self and (...) others. In recalling everyday life situations and in classical decision making paradigms, negative actions, negatives outcomes, and negative framing were attributed higher free will than positive ones. Free will attributions were mainly driven by action or outcome valence, but not intent. These findings show consistent support for the idea that free will underlies laypersons’ sense-making for accountability and change under negative circumstances. (shrink)
