What is a person, and how can a person come to know that she is a person identical to herself over time ? The article defends the view that the sense of being oneself in this sense consists in the ability to consciously affect oneself : in the memory of having affected oneself, joint to the consciousness of being able to affect oneself again. In other words, being a self requires a capacity for metacognition (control and monitoring of one's own (...) internal states). This view is compatible with the hypothesis that the self is a dynamic representation emerging out of a higher level control system, - valuation control - whose articulation with control of plans and perceptual/motor control is discussed in the context of normal and pertrubed agency.

The self seems to be a unitary entity remaining stable across time. Nevertheless, current theorizing conceptualizes the self as a number of interacting sub-systems involving perception, intention and action (self-model). One important function of such a self-model is to distinguish between events occurring as a result of one's own actions and events occurring as the result of somebody else's actions. We conducted an fMRI experiment that compared brain activation after an abrupt mismatch between one's own movement and its visual consequences (...) with an abrupt mismatch between one's own movement and somebody else's visually perceived hand movement. A right fronto-parietal network was selectively active during a sudden mismatch between one's own observed and performed hand action. (shrink)

Sceptics vis-à-vis introspection often base their scepticism on ‘phenomenological disputes’, ‘introspective disagreement’, or ‘introspective disputes’ (Kriegel, 2007; Bayne and Spener, 2010; Schwitzgebel, 2011): introspectors massively diverge in their opinions about experiences, and there seems to be no method to resolve these issues. Sceptics take this to show that introspection lacks any epistemic merit. Here, I provide a list of paradigmatic examples, distill necessary and sufficient conditions for IDs, present the sceptical argument encouraged by IDs, and review the two main strategies (...) to reject such a scepticism. However, both types of strategies are unsatisfactory. In order to save introspection from the looming sceptical threat, I advocate a deflationary strategy, based on either an ‘Argument from Perceptual Kinship’ or an ‘Argument from Ownership’. In the end, there cannot be any genuine IDs, for nothing can fulfil the reasonable conditions for IDs. What looks like IDs may instead be indicators of phenomenal variation. Debates that look like IDs may then arise even if introspection were a perfect method to know one’s mind. Thus, scepticism vis-à-vis introspection based on IDs rests on shaky grounds. (shrink)

How do I know that I am the person who is moving? According to Wittgenstein (1958), the sense of agency involves a primitive notion of the self used as subject, which does not rely on any prior perceptual identification and which is immune to error through misidentification. However, the neuroscience of action and the neuropsychology of schizophrenia show the existence of specific cognitive processes underlying the sense of agency—the ‘‘Who'' system (Georgieff & Jeannerod, 1998) which is disrupted in delusions of (...) control (Frith, 1992). Yet, we have to be careful in the interpretation of such clinical symptoms, which cannot be so easily reduced to deficit of action monitoring or to lack of action awareness. Moreover, we should refine the definition of the sense of agency by distinguishing the sense of initiation and the sense of one's own movements. A conceptual analysis of the empirical data will lead us to establish the taxonomy of the different levels of action representations. (shrink)

L’hystérie se définit comme un déficit fonctionnel sans cause organique. Par exemple, certains patients sont incapables de se mouvoir volontairement, comme s’ils étaient véritablement paralysés, sans que l’on puisse fournir une explication physiologique. À l’inverse, les patients souffrant d’anosognosie sont véritablement paralysés, mais affirment pouvoir bouger. Ces pathologies résultent toutes deux d’un trouble de la conscience de la capacité à agir : les uns croient qu’ils ne peuvent pas agir alors qu’ils le pourraient et les autres croient pouvoir agir alors (...) qu’ils en sont incapables. Mais de quoi dépend cette forme spécifique de conscience ? En comparant ces deux syndromes miroirs, je chercherai à révéler les processus mis en jeu par la conscience de la capacité à agir et à jeter un jour nouveau sur l’hystérie. S’agit-il d’un trouble de la volonté, et si oui, à quel niveau se produit-il ? J’analyserai ainsi les relations respectives entre la conscience de la capacité d’agir et la conscience d’agir, et montrerai le rôle joué par l’image corporelle. (shrink)

This paper defends the view that knowledge about one's own intentions can be gained in part through perception, although not through introspection. The various kinds of misperception of one's intentions are discussed. The latter distinction is applied to the analysis of schizophrenic patients' delusion of control.

This article summarizes how I came to deal with the subject matter of action, the main claims that I have defended, the prospects for future research, the interdisciplinary collaborations that are needed, and the obstacles to be surmounted.

This book chapter aims at exploring how intentional a piece of behavior should be to count as an action, and how a minimal view on action, not requiring a richly intentional causation, may still qualify such a behavior as voluntary.

Experience of agency in patients with schizophrenia involves an interesting dissociation; these patients demonstrate that one can have a thought or perform an action consciously without being conscious of thinking or acting as the motivated agent, author of that thought or of that action. This chapter examines several interesting accounts of this dissociation, and aims at showing how they can be generalized to thought insertion phenomena. It is argued that control theory allows such a generalization; three different comparators need to (...) be distinguished: the sense of subjectivity relies on a comparator in which motivation and emotion play a structuring role. The sense of agency emerges in a system that delivers a rough categorization of self-generated – versus other- generated – actions and mental activities. A third system specializes in the social evaluation of the effects of an action, intention or other thought process, given certain goals in self or in others. (shrink)
