Background Autism spectrum disorder (ASD) is associated with atypical neural activity in resting-state. Most of the studies have focused on abnormalities in alpha-frequency, as a marker of ASD dysfunctions. However, few have explored alpha synchronization, with a specific interest in resting-state networks: the default mode network (DMN), the senso...

Models of posttraumatic stress disorder (PTSD) suggest that the hippocampus is key to the persistence of traumatic memory. Yet very little is known about the precise changes that take place in this structure, nor their relation with PTSD symptoms. Previous studies have mostly used magnetic resonance imaging (MRI) at low resolutions, making it impos...

Autism spectrum disorder (ASD) is characterized by atypical perception, including processing that is biased toward local details rather than global configurations. This bias may impact on memory. The present study examined the effect of this perception on both implicit (Experiment 1) and explicit (Experiment 2) memory in conditions that promote eit...

Autobiographical memory (AM) is closely linked to the self-concept, and fulfills directive, identity, social, and adaptive functions. Individuals with autism spectrum disorder (ASD) are now known to have atypical AM, which may be closely associated with social communication difficulties. This may result in qualitatively different autobiographical n...

This study tested whether adults with autism spectrum disorder (ASD) show the same pattern of difficulties and absence of age‐related differences in short‐term memory (STM) as those that have been reported in episodic long‐term memory (LTM). Fifty‐three adults with ASD (age range: 25–65 years) were compared to 52 age‐, biological sex‐, and intellig...

Behavioral data on episodic recollection in autism spectrum disorders (ASD) point limited relational memory functioning. However, the involvement of successive memory processes in the profile of episodic memory in ASD needs more study. Here, we used event‐related potentials (ERP) to investigate the time course of episodic recollection with an assoc...

Post-traumatic stress disorder (PTSD) is characterized by intrusions, re-experiencing, avoidance and hyperarousal. These symptoms might be linked to dysfunction in core neurocognitive networks subserving self-referential mental processing (default mode network, DMN), detection of salient stimuli (salience network, SN) and cognitive dysfunction (cen...

Reexperiencing symptoms in adolescent Post‐Traumatic Stress Disorder (PTSD) are characterized by the apparition of vivid intrusive images of the traumatic event. The emergence of these intrusions is thought to be related to a deficiency in context processing and could then be related to hippocampal alterations. The hippocampus is a complex structur...

Encoding and retrieval processes in memory for pairs of pictures are thought to be influenced by inter-item similarity and by features of individual items. Using Event-Related Potentials (ERP), we aimed to identify how these processes impact on both the early mid-frontal FN400 and the Late Positive Component (LPC) potentials during associative retr...

Some studies suggest that childhood traumas, particularly when they are interpersonal, are associated with more severe Post-Traumatic Stress Disorder (PTSD) at adulthood and have a critical impact on the development of self-concept. Recent findings point to serious impairments in representations of self in PTSD adolescents, but nothing is known abo...

We proposed to explore the functional brain changes during a self-reference processing (SRP) task in adolescents with sexual abuse-related post-traumatic stress disorder (N = 10), compared with healthy adolescents (N = 10). While patients showed no behavioral disturbances in SRP, they exhibited changes in activity and connectivity in regions involv...

Pendant longtemps, les études cognitives ont négligé les liens entre mémoire et émotions, voire même totalement écarté de leurs champs de recherche. Aujourd’hui, l’étude des émotions, au travers de leur expression physiologique, comportementale jusqu’à leur expérience subjective, est en pleine expansion. De par leur nature, les émotions nécessitent...

Negative self-appraisal may underline the development and maintenance of Post-traumatic stress disorder (PTSD). This phenomenon may be exacerbated in individuals with PTSD occurring during adolescence with a critical impact on brain development and personal identity. However, no study has evaluated changes in self-appraisal and the functional brain...

Autobiographical memory implicates many cognitive functions including executive functions, language, social cognition, self-consciousness, perceptual and emotional processes. Autobiographical memory can be described into two components: episodic memories and personal semantic knowledge, both closely related to the self. For these reasons, the devel...

Some studies highlight similarities between Autism Spectrum Disorder (ASD) and healthy aging. Indeed, the decline in older individuals' ability to create a unified representation of the individual features of an event is thought to arise from a disruption of binding within the episodic buffer of working memory (WM) as the same way as observed in AS...

Episodic retrieval is characterized by the subjective experience of remembering. This experience enables the co-ordination of memory retrieval processes and can be acted on metacognitively. In successful retrieval, the feeling of remembering may be accompanied by recall of important contextual information. On the other hand, when people fail (or st...

Episodic memory refers to the capacity to bind multimodal memories to constitute a unique personal event. Most developmental studies on episodic memory focused on one specific component, i.e., the core factual information. The present study examines the relevance of a novel episodic paradigm to assess its developmental trajectories in a more compre...

Autobiographical memory (AM) and social cognition share common properties and both are affected in autism spectrum disorders (ASD). So far, most of the scant research in ASD has concerned adults, systematically reporting impairment of the episodic component. The only study to be conducted with children concluded that they have poorer personal seman...

Conway's autobiographical memory (AM) model postulates that memories are not stored in a crystallised form in long-term memory but are reconstructed at time of retrieval via executive and binding processes, to create a temporary multimodal representation from different AM knowledge. Traumatic brain injury (TBI) impairs AM recollection. However, no...

Currently, there is no consensus on the delay necessary to a complete recovery after a transient global amnesia (TGA). However, it seems that slight episodic memory disorders extend beyond 24h. Although this impairment is probably a consequence of the TGA attack, other factors such as patients' emotional state can intervene in the slow recovery pro...
