This paper discusses the content of agency awareness. It contrast three elements in content: what the goal is, how it is to be reached, and who is having the goal/performing the action ? Marc Jeannerod's claim that goal representations are self-other neutral is discussed. If goal representations are essentially sharable, then we do not understand other people by projecting a piece of internal knowledge on to them, as often assumed. The problem which our brain has to solve is the converse problem : determining who the agent is, once a goal is identified. This view has interesting consequences on the theory of mentalization. One can plausibly speculate that observing action, with an additional simulatory component for action memory, form major building blocks in understanding other minds. Metarepresenting, in this perspective, would depend on additional executive capacities for maintaining distinct the inferences from diverse simulated contexts of action.

In Intentionality and other works, John Searle establishes himself as a leading defender of the view that consciousness of what one is doing is always a component of one'€™s action. In this paper I focus on problems with Searle'€™s view to establish that there are actions in which the agent is not at all aware of what she is doing. I argue that any theory that misses this sort of action keeps us from important insights into autonomy, self-knowledge and responsibility.

The experience of conscious will is the feeling that we are doing things. This feeling occurs for many things we do, conveying to us again and again the sense that we consciously cause our actions. But the feeling may not be a true reading of what is happening in our minds, brains, and bodies as our actions are produced. The feeling of conscious will can be fooled. This happens in clinical disorders such as alien hand syndrome, dissociative identity disorder, and schizophrenic auditory hallucinations. And in people without disorders, phenomena such as hypnosis, automatic writing, Ouija board spelling, water dowsing, facilitated communication, speaking in tongues, spirit possession, and trance channeling also illustrate anomalies of will – cases when actions occur without will or will occurs without action. This book brings these cases together with research evidence from laboratories in psychology to explore a theory of apparent mental causation. According to this theory, when a thought appears in consciousness just prior to an action, is consistent with the action, and appears exclusive of salient alternative causes of the action, we experience conscious will and ascribe authorship to ourselves for the action. Experiences of conscious will thus arise from processes whereby the mind interprets itself – not from processes whereby mind creates action. Conscious will, in this view, is an indication that we think we have caused an action, not a revelation of the causal sequence by which the action was produced. Key Words: apparent mental causation; automatism; conscious will; determinism; free will; perceived control.

A number of cognitive and behavioral variables influence the performance in tasks of theory of mind (ToM). Since two of the most important variables, memory and explicit expression, are impaired in schizophrenic patients, the ToM appears inconsistent in these patients. An ideal instrument of ToM should therefore account for deficient memory and impaired ability of these patients to explicitly express intentions. If such an instrument is developed, it should provide information that can be used not only to understand the pathophysiology but also to monitor patients.

Book description: * Seventeen brand-new essays by leading philosophers and psychologists * Genuinely interdisciplinary work, at the forefront of both fields * Includes a valuable introduction, uniting common threads Leading philosophers and psychologists join forces to investigate a set of problems to do with agency and self-awareness, in seventeen specially written essays. In recent years there has been much psychological and neurological work purporting to show that consciousness and self-awareness play no role in causing actions, and indeed to demonstrate that free will is an illusion. The essays in this volume subject the assumptions that motivate such claims to sustained interdisciplinary scrutiny. Patients with Anarchic Hand syndrome sometimes find their hands perform apparently goal-directed actions which the patients disown, yet seem to be unable to suppress (for example, reaching out for someone else's food in a restaurant). On the face of it, these patients lack the kind of control and self-awareness we ordinarily take ourselves to have when acting intentionally. Questions raised by this phenomenon include: What is involved in being aware of an action as one's own? What is the nature of the control these patients are lacking and which characterizes normal intentional actions? What is the relation between a priori explanations of consciousness and self-consciousness, on the one hand, and empirical work on the information-processing mechanisms involved in action control, on the other? Questions of action control and self-awareness tend to be treated separately in both philosophy and psychology. The central idea behind this volume is that outstanding unresolved issues on both topics, and in both disciplines, can only be resolved by an interdisciplinary examination of the relations between them. The editors' useful introductory essay offers a guide to cross-disciplinary reading of the contributions, and makes connections between them explicit. The book will be compulsory reading for psychologists and philosophers working on action explanation, and for anyone interested in the relation between the brain sciences and consciousness.

This article reviews experimental evidence for a specific sensorimotor function which can be dissociated from higher level representations of space. It attempts to delineate this function on the basis of results obtained by psychophysical experiments performed with brain damaged and healthy subjects. Eye and hand movement control exhibit automatic features, such that they are incompatible with conscious control. In addition, they rely on a reference frame different from the one used by conscious perception. Neuropsychological cases provide a strong support for this specific motor representation of space, which can be spared in patients with lesions of primary sensory systems who have lost conscious perception of visual, tactile or proprioceptive stimuli. Observation of these patients also showed that their motor behavior can be ''attracted'' by a goal only under specific conditions, that is, when the response is immediate and when no cognitive representation of this goal is elaborated at the same time. Beyond the issue of the dissociation between an implicit motor representation and more cognitive processing of spatial information, the issue of the interaction between these two systems is thus a matter of interest. It is suggested that the conscious, cognitive representation of a stimulus can contaminate or override the short-lived motor representation, but no reciprocal influence seem to occur. The interaction observed in patients can also be investigated in normals. The literature provides examples of interaction between sensorimotor and cognitive framing of space, which confirm that immediate action is not mediated by the same system as delayed action, and that elaborating a categorial representation of the action goal prevents the expression of the short-lived sensorimotor representation. It is concluded that action can be controlled by a sensory system which is specialized for on-line processing of relevant goal characteristics. The temporal constraints of this system are such that it can affect the action before a full sensory analysis of this goal has been completed. The performance obtained on the basis of this spatial sensory processing suggests that short-lived motor representations may rather be considered as real ''presentation'' of the action world, which share its metric properties.

Recent studies have shown that schizophrenia may be a disease affecting the states of consciousness. The present study is aimed at investigating metamemory, i.e., the knowledge about one's own memory capabilities, in patients with schizophrenia. The accuracy of the Confidence level (CL) in the correctness of the answers provided during a recall phase, and the predictability of the Feeling of Knowing (FOK) when recall fails were measured using a task consisting of general information questions and assessing semantic memory. Nineteen outpatients were paired with 19 control subjects with respect to age, sex, and education. Results showed that patients with schizophrenia exhibited an impaired semantic memory. CL ratings as well as CL and FOK accuracy were not significantly different in the schizophrenic and the control groups. However, FOK ratings were significantly reduced for the patient group, and discordant FOK judgments were also observed more frequently. Such results suggest that FOK judgments are impaired in patients with schizophrenia, which confirms that schizophrenia is an illness characterized by an impaired conscious awareness of one's own knowledge.

Whoever paid the bill at the restaurant last night, will clearly remember doing it. Independently from the type of action, it is a common experience that being the agent provides a special strength to our memories. Even if it is generally agreed that personal memories (episodic memory) rely on separate neural substrates with respect to general knowledge (semantic memory), little is known on the nature of the link between memory and the sense of agency. In the present paper, we review results from two experiments investigating the effects of agency on both explicit and implicit memory traces. Performance of normal subjects is compared to that of schizophrenic patients in order to explore the role of awareness of action on memory. It is proposed that reliable first-person information is necessary to create a stable and coherent motor memory trace.

This paper offers a framework for consciousness of internal reality. Recent PET experiments are reviewed, showing partial overlap of cortical activation during self-produced actions and actions observed from other people. This overlap suggests that representations for actions may be shared by several individuals, a situation which creates a potential problem for correctly attributing an action to its agent. The neural conditions for correct agency judgments are thus assigned a key role in self/other distinction and self-consciousness. A series of behavioral experiments that demonstrate, in normal subjects, the poor monitoring of action-related signals and the difficulty in recognizing self-produced actions are described. In patients presenting delusions, this difficulty dramatically increases and actions become systematically misattributed. These results point to schizophrenia and related disorders as a paradigmatic alteration of a ''Who?'' system for self-consciousness.
