Nous avons récemment observé que le cortex préfrontal ventro-médial (CPFVM) est activé à la fois chez des sujets jeunes et âgés dans une tâche de jugement d’adjectifs nécessitant d’évaluer sa propre personnalité par rapport à celle d’un autre dans le contexte d’un prise de perspective à la première (1PP) et à la troisième (3PP) personne (Ruby et al., submitted). Nous avons poursuivi l’analyse de ces données par des analyses de connectivité fonctionnelle afin de déterminer le réseau des régions cérébrales associées à la performance des sujets jeunes et âgés. Les résultats montrent qu’en 1PP, l’activité du CPFVM est associée à celle du gyrus frontal inférieur et du gyrus parahippocampique chez les sujet âgés, mais uniquement à celle du cortex occipital chez les sujets jeunes. En 3PP, une connectivité fonctionnelle existe entre le CPFVM et le gyrus frontal médial, le gyrus frontal inférieur et les régions temporales supérieures chez les sujets âgées ; mais uniquement avec les régions occipitale et pariétale chez les sujets jeunes. Les régions cérébrales associées à l’activité du CPFVM chez les sujets jeunes ont été décrites comme impliquées dans la récupération en mémoire autobiographique ainsi que dans les processus de « mentalizing ». En ce qui concerne les personne âgées, le réseau cérébral découvert est relié à la récupération de souvenirs sémantique et épisodique (gyrus parahippocampique et temporal supérieur) mais aussi à l’attribution d’une valence émotionnelle à l’adjectif (gyrus frontal inférieur) et à la prise de perspective (gyrus frontal médial). Ces résultats indiquent (1) que le CPFVM est connecté à un réseau cérébral plus important chez les personnes âgées que chez les jeunes lors de jugement sur soi ; (2) que les sujets jeunes réalisent la tâche sur base d’informations autobiographiques seulement alors que les personnes âgées recrutent en plus des processus cognitifs de nature plus réflexive.

Being able to envision emotional events that might happen in the future has a clear adaptive value. This study addressed the functional neuroanatomy of this process and investigated whether it is modulated by temporal distance. Participants imagined positive and negative events pertaining to the near future or far future while their brain activity was measured with fMRI. The results demonstrate that the anterior part of the ventromedial prefrontal cortex (vmPFC) was more active in envisioning emotional events in the far future than in the near future, whereas the caudate nucleus was engaged in envisioning emotional (especially positive) situations in the near future. We argue that the anterior part of the vmPFC might assign emotional values to mental representations of future events that pertain to long-term goals. On the other hand, the caudate might support more concrete simulations of action plans to achieve rewarding situations in the near future. [less ▲]

It has been suggested that patients with schizophrenia experience a distorted sense of continuity of self across time. However, temporal aspects of self-processing have received little empirical attention in schizophrenia. In this study, the authors investigated schizophrenic patients' ability to generate specific mental images of their personal past and future. Results showed that patients recalled fewer specific past events than did healthy controls and were even more impaired in generating specific future events. These deficits were associated with positive symptoms but were not associated with negative symptoms or with performances on verbal fluency tasks. It is suggested that schizophrenic patients' failures to project themselves into specific past and future episodes might be related to difficulties in retrieving contextual details from memory, as well as disturbance of the sense of subjective time.

Precise brain regions are activated when a subject gives a judgment on himself. Those are the medial parietal cortex, essentially related to episodic memory processing, and the ventromedial prefrontal cortex, recruited for evaluating the personal valence of an information. These regions are not activated in Alzheimer's disease. The decrease of awareness for own deficits in a patient with Alzheimer's disease would depend on a reduction of episodic memory capacities and a worsening of judgment for self significance. [less ▲]

Research suggests that states of the body, such as postures, facial expressions, and arm movements, play central roles in social information processing. This study investigated the effects of approach/avoidance movements on memory for facial information. Faces displaying a happy or a sad expression were presented and participants were induced to perform either an approach (arm flexion) or an avoidance (arm extension) movement. States of awareness associated with memory for facial identity and memory for facial expression were then assessed with the Remember/Know/Guess paradigm. The results showed that performing avoidance movements increased Know responses for the identity, and Know/Guess responses for the expression, of valence-compatible stimuli (i.e., sad faces as compared to happy faces), whereas this was not the case for approach movements. Based on these findings, it is suggested that approach/avoidance motor actions influence memory encoding by increasing the ease of processing for valence-compatible information. [less ▲]

Phenomenal characteristics of autobiographical memories and imagined experiences were examined in checking- and non-checking-prone individuals. Participants were asked to retrieve a positive, a negative and a neutral memory, and to imagine a positive, a negative and a neutral experience. They were then requested to evaluate each event according to characteristics such as sensory and contextual details. The main results revealed that non-checking-prone participants reported more general vividness than checking-prone individuals for real events. In addition, non-checking-prone individuals reported more visual details and vividness for real than imagined experiences, while no difference between real and imagined events was found for checking-prone participants. These results suggest that checking-prone participants report poor memories of real events, which could in turn explain their difficulties distinguishing between real and imagined events.

Relatively few studies have examined memory bias for social stimuli in depression or dysphoria. The aim of this study was to investigate the influence of depressive symptoms on memory for facial information. A total of 234 participants completed the Beck Depression Inventory II and a task examining memory for facial identity and expression of happy and sad faces. For both facial identity and expression, the recollective experience was measured with the Remember/Know/Guess procedure (Gardiner Richardson-Klavehn, 2000). The results show no major association between depressive symptoms and memory for identities. However, dysphoric individuals consciously recalled (Remember responses) more sad facial expressions than non-dysphoric individuals. These findings suggest that sad facial expressions led to more elaborate encoding, and thereby better recollection, in dysphoric individuals. [less ▲]

People's self-images are grounded in autobiographical memories and, in particular, in the phenomenological experience associated with remembering. The desire to increase or maintain the positivity of the self-image (i.e., the self-enhancement motive) might thus play an important role in shaping memory phenomenology. This study examined this hypothesis by asking participants to recall positive and negative events that involve self-evaluations (i.e., pride and shame) and positive and negative events that involve evaluations about others (i.e., admiration and contempt); various phenomenological characteristics (e.g., sensory details, feeling of re-experiencing) were assessed using rating scales. The results show a positivity bias (i.e., subjectively remembering positive events with more details than negative events) for events that involve self-evaluations but not for events that involve evaluations of others. In addition, this bias was stronger for people high in self-esteem. It is concluded that biases affecting the phenomenology of autobiographical memory are part of the arsenal of psychological mechanisms people use to maintain a positive self-image. [less ▲]

The processing of personal changes across time and the ability to differentiate between representations of present and past selves are crucial for developing a mature sense of identity. In this study, we explored the neural correlates of self-reflection across time using functional magnetic resonance imaging (fMRI). College undergraduates were asked to reflect on their own psychological characteristics and those of an intimate other, for both the present time period (i.e. at college) and a past time period (i.e. high school years) that involved significant personal changes. Cortical midline structures (CMS) were commonly recruited by the four reflective tasks (reflecting on the present self, past self, present other and past other), relative to a control condition (making valence judgments). More importantly, however, the degree of activity in CMS also varied significantly according to the target of reflection, with the ventral and dorsal medial prefrontal cortex and the posterior cingulate cortex being more recruited when reflecting on the present self than when reflecting on the past self or when reflecting on the other person. These findings suggest that CMS may contribute to differentiate between representations of present and past selves. [less ▲]

Previous studies indicate that the encoding of new facial identities in memory is influenced by the type of expression displayed by the faces. fit the current study, the authors investigated whether or not this influence requires attention to be explicitly directed toward the affective meaning of facial expressions. In a first experiment, the authors found that facial identity was better recognized when the faces were initially encountered with a happy rather than an angry expression, even when attention wits oriented toward facial features other than expression. Using the Remember/Know/Guess paradigm in a second experiment, the authors found that the influence of facial expressions on the conscious recollection of facial identity was even more pronounced when participants' attention wits not directed toward expressions. It is suggested that the affective meaning of facial expressions automatically modulates the encoding of facial identity in memory. [less ▲]

The medial prefrontal cortex (MPFC) appears to play a prominent role in two fundamental aspects of social cognition, that is, self-referential processing and perspective taking. However, it is currently unclear whether the same or different regions of the MPFC mediate these two interdependent processes. This functional magnetic resonance imaging study sought to clarify the issue by manipulating both dimensions in a factorial design. Participants judged the extent to which trait adjectives described their own personality (e.g., 'Are you sociable?') or the personality of a close friend (e.g., 'Is Caroline sociable?') and were also asked to put themselves in the place of their friend (i.e., to take a third-person perspective) and estimate how this person would judge the adjectives, with the target of the judgments again being either the self (e.g., 'According to Caroline, are you sociable?') or the other person (e.g., 'According to Caroline, is she sociable?'). We found that self-referential processing (i.e., judgments targeting the self vs. the other person) yielded activation in the ventral and dorsal anterior MPFC, whereas perspective taking (i.e., adopting the other person's perspective, rather than one's own, when making judgments) resulted in activation in the posterior dorsal MPFC; the interaction between the two dimensions yielded activation in the left dorsal MPFC. These findings show that self-referential processing and perspective taking recruit distinct regions of the MPFC and suggest that the left dorsal MPFC may be involved in decoupling one's own from other people's perspectives on the self.

We aimed at investigating social disability and its cerebral correlates in frontotemporal dementia (FTD). To do so, we contrasted answers of patients with early-stage FTD and of their relatives on personality trait judgment and on behavior prediction in social and emotional situations. Such contrasts were compared to control contrasts calculated with answers of matched controls tested with their relatives. in addition, brain metabolism was measured in patients with positron emission tomography and the [F-18]fluorodeoxyglucose method. Patients turned out to be as accurate as controls in describing their relative's personality, but they failed to predict their relative's behavior in social and emotional circumstances. Concerning the self, patients were impaired both in Current personality assessment and in prediction of their own behavior. Those two self-evaluation measures did not correlate. Only patients' anosognosia for social behavioral disability was found to be related to decreased metabolic activity in the left temporal pole. Such results suggest that anosognosia for social disability in FTD originates in impaired processing of emotional autobiographical information, leading to a self-representation that does not match current behavior. Moreover, we propose that perspective-taking disability participates in anosognosia, preventing patients from correcting their inaccurate self-representation based on their relative's perspective.

Emotional events are usually better remembered than neutral ones. This effect is mediated in part by a modulation of the hippocampus by the amygdala. Sleep plays a role in the consolidation of declarative memory. We examined the impact of sleep and lack of sleep on the consolidation of emotional (negative and positive) memories at the macroscopic systems level. Using functional MRI (fMRI), we compared the neural correlates of successful recollection by humans of emotional and neutral stimuli, 72 h after encoding, with or without total sleep deprivation during the first post-encoding night. In contrast to recollection of neutral and positive stimuli, which was deteriorated by sleep deprivation, similar recollection levels were achieved for negative stimuli in both groups. Successful recollection of emotional stimuli elicited larger responses in the hippocampus and various cortical areas, including the medial prefrontal cortex, in the sleep group than in the sleep deprived group. This effect was consistent across subjects for negative items but depended linearly on individual memory performance for positive items. In addition, the hippocampus and medial prefrontal cortex were functionally more connected during recollection of either negative or positive than neutral items, and more so in sleeping than in sleep-deprived subjects. In the sleep-deprived group, recollection of negative items elicited larger responses in the amygdala and an occipital area than in the sleep group. In contrast, no such difference in brain responses between groups was associated with recollection of positive stimuli. The results suggest that the emotional significance of memories influences their sleep-dependent systems-level consolidation. The recruitment of hippocampo-neocortical networks during recollection is enhanced after sleep and is hindered by sleep deprivation. After sleep deprivation, recollection of negative, potentially dangerous, memories recruits an alternate amygdalo-cortical network, which would keep track of emotional information despite sleep deprivation.

INTRODUCTION: Studies suggest an important role of disturbances of self in schizophrenia and in schizotypy. Based on findings from a previous study (Bredart & Young, 2004), we developed a questionnaire assessing self-face recognition failures in everyday life (Self-Face Recognition Questionnaire; SFRQ) to investigate the relations between dimensions of schizotypy (cognitive-perceptual, interpersonal, disorganised) and self-face recognition disturbances. METHODS: A sample of nonclinical participants (n = 170) completed the SFRQ and the Schizotypal Personality Questionnaire. RESULTS: Factor analysis of SFRQ items revealed a clear three-factor structure consisting of: (1) self-face recognition difficulties, (2) unusual perception of own or other faces, and (3) other-face recognition difficulties. Correlational analyses between schizotypy dimensions and the SFRQ revealed that only the cognitive-perceptual and disorganised schizotypy dimensions correlated significantly with the SFRQ. By contrast, the interpersonal schizotypy dimension was not associated with the SFRQ. CONCLUSIONS: Findings provide further support that positive (cognitive-perceptual) and negative (interpersonal) schizotypy represent discrete neurobehavioural dimensions. The theoretical implications of these findings are discussed. [less ▲]
