To test the hypothesis of a participation of inner speech in self-referential activity we reviewed 59 studies measuring brain activity during processing of self-information in the following self-domains: agency, self-recognition, emotions, personality traits, autobiographical memory, preference judgments, and REST. The left inferior frontal gyrus (LIFG) has been shown to sustain inner speech use. We calculated the percentage of studies reporting LIFG activity for each self-dimension. 55.9% of all studies reviewed identified LIFG (and presumably inner speech) activity during self-awareness tasks. Furthermore, the LIFG was more frequently recruited during conceptual tasks (e.g., emotions, traits) than during perceptual tasks (e.g., agency, self-recognition). This supports the view of a relative involvement of inner speech in self-reflective processes. Crown Copyright © 2007 Published by Elsevier Inc. All rights reserved.

In this commentary I use recent empirical evidence and theoretical analyses concerning the importance of language and the meaning of self-recognition to reevaluate the claim that the right mute hemisphere in commissurotomized patients possesses a full consciousness. Preliminary data indicate that inner speech is deeply linked to self-awareness; also, four hypotheses concerning the crucial role inner speech plays in self-focus are presented. The legitimacy of self-recognition as a strong operationalization of self-awareness in the right hemisphere is also questioned on the basis that it might rather tap a preexisting body awareness having little to do with an access to mental events. I conclude with the formulation of an alternative interpretation of commissurotomy according to self-awareness — a “complete” one in the left hemisphere and a “primitive” one in the right hemisphere

Quite a few recent models are rapidly introducing new concepts describing different levels of consciousness. This situ- ation is getting confusing because some theorists formulate their models without making reference to existing views, redun- dantly adding complexity to an already difficult problem. In this paper, I present and compare nine neurocognitive models to highlight points of convergence and divergence. Two aspects of consciousness seem especially important: perception of self in time and complexity of self-representations. To this I add frequency of self-focus, amount of self-related informa- tion, and accuracy of self-knowledge. Overall, I conclude that many novel concepts (e.g., reflective, primary, core, extend- ed, recursive, and minimal consciousness) are useful in helping us distinguish between delicate variations in consciousness and in clarifying theoretical issues that have been intensely debated in the scientific literature—e.g., consciousness in rela- tion to mirror self-recognition and language

This article suggests that one possible function of imagery is its role as a mediator of self-awareness and its significance in the acquisition of self- information. Sparse allusions of a relation between imagery and self-awareness have been mentioned before, but no real attempt to account for the nature of the link has been undertaken. The following hypothesis is put forward: some cognitive processes are capable of internally reproducing social mechanisms responsible for self-awareness. One such mechanism is the opportunity to see oneself as one is seen by others. It is postulated that imagery internalizes this social mechanism because mental images empower us to literally see ourselves acting (or having behaved) in given ways as others could see (or have seen) us acting. When one mentally sees oneself behaving in a given fashion, one is self-aware; furthermore, when one reflects on past behaviors by using mental images, one can deduct aspects of one's past functioning from what is internally seen, that is, acquire self- information and build a self-concept. The importance for mental images to have in their content the organism's body image (especially one's facial features) is underlined, and experiences with self-reflecting devices (e.g., mirrors) are presumed to be crucial in that respect

Hughes and Nicholson suggest that recognizing oneself is easier from face vs. voice stimuli, that a combined presentation of face and voice actually inhibits self-recognition relative to presentation of face or voice alone, that the left hemisphere is superior in self-recognition to the right hemisphere, and that recognizing self requires more effort than recognizing others. A re-examination of their method, data, and analyses unfortunately shows important ceiling effects that cast doubts on these conclusions

Ce texte propose une définition de la conscience de soi et explique en quoi cette capacité naît du monde social. Il est postulé que ce dernier permet un mouvement de recul - une «distanciation » - par rapport à soi, et que le cerveau reproduit ce mouvement grâce à certains processus cognitifs qui en ont été imprimés. Parmi ceux-ci, on retrouve le langage intérieur, qui, par analogie, agirait comme un miroir interne capable de confronter l'expérience subjective à elle-même; de cette confrontation naîtrait le soi. Un argument est présenté en faveur de la supériorité du langage intérieur sur d'autres processus cognitifs impliqués dans la conscience de soi. Le problème de la conscience de soi chez les primates est abordé, et l'article conclut sur diverses réflexions ayant trait à la schizophrénie, la prière, la méditation, et les drogues psychodysleptiques.This text proposes a definition of self-awareness and explains its social origin. It is postulated that the social milieu permits a movement to a more objective perspective for self- perception, and that this movement is then reproduced in the brain by specific cognitive processes. It is suggested that inner speech represents one such cognitive processes, which acts like a mirror to reflect subjective experience back upon itself-, the self would be generated by this reflective activity. It is argued that inner speech has a pre-eminent position among the cognitive processes implicated in self-awareness. The problem of self-awareness in primates is discussed, and the article concludes with ideas concerning schizophrenia, prayer, medi- tation, and psychodysleptic drugs

We all spend time analyzing our inner thoughts and feelings; past research looked at this activity as being unitary in nature (i.e., simply focusing on the self), examined how frequently people introspect, and identified the effects of self-focus on behavior. Current studies indicate that people actually engage in two different types of self-analysis: self-reflection (enjoying analyzing the self) and self-rumination (not being able to shut off thoughts about the self), each leading to opposite consequences

In this commentaryI evaluate the claim made byKeenan, Nelson, OÕConnor, and Pascual-Leone (2001) that since self-recognition results from right hemispheric activity, self-awareness too is likely to be produced by the activity of the same hemisphere. This reasoning is based on the assumption that self-recognition represents a valid operationalization of self-awareness; I present two views that challenge this rationale. Keenan et al. also support their claim with published evidence relating brain activityand self-awareness; I closelyexamine their analysis of one specific review of literature and conclude that it appears to be biased. Finally, recent research suggests that inner speech (which is associated with left hemispheric activity) is linked to self-awareness—an observation that further casts doubt on the existence of a right hemispheric self-awareness.

Inner speech represents the activity of talking to oneself in silence. It can be assessed with questionnaires, sampling methods, and electromyographic recordings of articulatory movements. Inner speech has been linked to thought processes and self-awareness. Private speech (speech-for-self emitted aloud by children) serves an important self-regulatory function. The frequency of private speech follows an inverted-U relation with age, peaking at 3-4 years of age and disappearing at age 10. Social and inner speech share a common neurological basis: Broca’s area. Dysfunctional self-talk is known to mediate many pathological conditions; negative selfverbalizations have a more significant debilitating impact than positive ones.

In her 2006 book ‘‘My Stroke of Insight” Dr. Jill Bolte Taylor relates her experience of suffering from a left hemispheric stroke caused by a congenital arteriovenous malformation which led to a loss of inner speech. Her phenomenological account strongly suggests that this impairment produced a global self-awareness deficit as well as more specific dysfunctions related to corporeal awareness, sense of individuality, retrieval of autobiographical memories, and self-conscious emotions. These are examined in details and corroborated by numerous excerpts from Taylor’s book. Ó 2008 Elsevier Inc. All rights reserved.

Merker’s definition of consciousness excludes self-reflective thought, making his proposal for decorticate consciousness not particularly groundbreaking. He suggests that brainstem sites are neglected in current theories of consciousness. This is so because broader definitions of consciousness are used. Split-brain data show that the cortex is important for full-blown consciousness; also, behaviors exhibited by hydranencephaly patients and decorticated rats do not seem to require reflective consciousness

Sttrrtmory.— It has been suggested recently that self-awareness is cognitively mediated by inner speech and that this hypothesis could be tested by using the private speech paradigm. This paper describes a study in which the creation of a state of self-awareness was attempted in children to test the viability of a research strategy based on private speech and used to explore the hypothesis of a link between selfawareness and inner speech, and to test directly this hypothesis by comparing the incidence of private speech in self-aware and control conditions. 32 children were asked to evaluate the attractiveness of pictures when in front of a mirror (a widely used self-focusing stimulus) and with no mirror. Reliably more favorable ratings of the images..

In my 2003 SCR paper “Inner speech and conscious experience” (LINK) I put forward the notion that we most often need to talk to ourselves in order to understand who we are. That is, inner speech is frequently required to access self-information and to gradually build a self- concept. To illustrate, let’s imagine that you want to reflect on an abdominal pain you are currently experiencing. It is very likely that you will engage in an internal monologue, thinking “Why is it that my belly hurts? I feel cramps... Ha! I get it—I skipped breakfast...” You could go on and also notice: “I’ve been missing breakfast often lately... I tend to sleep in, I don’t eat breakfast, and by noon I’m starving... And I didn’t go to the gym as often as I should have... This is bad—I’m getting _lazy_...” Here the adjective “lazy” constitutes the conclusion that you have drawn from your inner monologue; it may then become a more or less permanent part of your self-concept

Self-awareness represents the capacity of becoming the object of one’s own attention. In this state one actively identifies, processes, and stores information about the self. This paper surveys the self-awareness literature by emphasizing definition issues, measurement techniques, effects and functions of self-attention, and antecedents of self-awareness. Key self-related concepts (e.g., minimal, reflective consciousness) are distinguished from the central notion of self-awareness. Reviewed measures include questionnaires, implicit tasks, and self-recognition. Main effects and functions of self-attention consist in selfevaluation, escape from the self, amplification of one's subjective experience, increased self-knowledge, self-regulation, and inferences about others' mental states (Theory-of-Mind). A neurocognitive and socioecological model of self-awareness is described in which the role of face-to-face interactions, reflected appraisals, mirrors, media, inner speech, imagery, autobiographical knowledge, and neurological structures is underlined

Summary.— Recent empirical work in social cognition suggests that in building a self-concept people make inferences about themselves based on overt behavior or private thoughts and feelings. This article addresses the question of how, exactly, people make these inferences about themselves and raises the possibility that they do so through self-talk. It is proposed that the more on talks to oneself to construct a selfimage, the more this image will gain coherence and sophistication. A correlational study was conducted to explore the relation between richness of the self-concept (using the W-A-Y) and natural disposition to talk to oneself (using a pilot questionnaire). A moderate but positive correlation of .30 is obtained. The article concludes with clinical implications.

Little is known with regard to the precise cognitive tools the self uses in acquiring and processing information about itself. In this article, we underline the possibility that inner speech might just represent one such cognitive process. Duval and Wicklund’s theory of self-awareness and the selfconsciousness, and self-knowledge body of work that was inspired by it are reviewed, and the suggestion is put forward that inner speech parallels the state of self-awareness, is more frequently used among highly self-conscious persons, and represents an effective, if not indispensable, tool involved in the formation of the self-concept. The possibility is also raised that the extent to which one uses inner speech could partially explain individual differences in self-consciousness and self-knowledge. A selective review of the private and inner speech literature is presented, and some possible ways of testing the hypothesis by using pre-existing techniques are proposed in the hope of stimulating empirical investigations. Some implications are outlined in conclusion.

This article raises the question of how self-talk mediates self-awareness. It is argued that the process of acquiring self-information can be seen as a problem-solving task, and that self-talk can facilitate this process (as it does for any other problem) by promoting a precise formulation and approach to the problem, by adequately focusing attention on the task, and through constant self-evaluations. A complementary analysis of the possible characteristics of an effective internal dialogue in the acquisition of self-information is undertaken. Among other things, taking others' perspective through self-talk, possessing a rich vocabulary about oneself, and paying attention to the content of one's self-talk are believed to be important in that respect. Clinical implications raised by this analysis are also discussed
