Background Self-disorders constitute a core feature of the schizophrenia spectrum, including early stages such as first-episode psychosis (FEP). These disorders impact the minimal Self, or bodily self-consciousness, which refers to the basic, pre-reflective sense of embodied experience. The minimal Self is intrinsically linked to episodic memory, w...

Episodic autobiographical memory (EAM) is a long-term memory system of personally experienced events with their context – what, where, when – and subjective elements, e.g., emotions, thoughts, or self-reference. EAM formation has rarely been studied in a controlled, real-life-like paradigm, and there is no predictive model of long-term retrieval fr...

Introduction. Few studies have focused on social cognition in dementia with Lewy bodies (DLB), even though some brain structures being well known as underlying social cognitive processes are directly impacted in this disease. Furthermore, social cognition processes have been mostly studied independently using evaluations with poor ecological validi...

Vagally mediated heart rate variability (vmHRV) at resting state has been associated to cognitive functions dependent on cognitive control, such as memory. However, little is known about the phasic interaction between cognitive and autonomic control. In a pre‐registered within‐between‐subject designed experiment, the potential of vmHRV biofeedback...

L’Institut de Psychologie de l’Université Paris Cité est un acteur majeur de la formation des psychologues en France, soutenu par des recherches de haut niveau. L’Institut a mis à profit les possibilités offertes par les technologies numériques pour innover dans la recherche et l’enseignement, mettant en place une nouvelle plateforme technologique...

This study examines the cognitive processes shared by episodic autobiographical memory (EAM) and episodic future thinking (EFT), with a focus on how temporal distance (TD) to the present affects episodicity in both. Using virtual reality, our investigation employs a “time machine” to immerse participants in different temporal contexts, priming simu...

Mind wandering (MW) occurs when our attention spontaneously shifts from the task at hand to inner thoughts. MW is often future-oriented and may help people remember to carry out their planned actions (Prospective Memory, PM). Past-oriented MW might also play a critical role in boosting PM performance. Sixty participants learned 24 PM items and reca...

Vagally-mediated heart rate variability (vmHRV) at resting-state has been associated to cognitive functions dependent on cognitive control, such as memory. However, little is known about the phasic interaction between cognitive and autonomic control. In a pre-registered within-between-subject designed experiment, the potential of vmHRV biofeedback...

Recent studies suggest that the human body plays a critical role in encoding and retrieving episodic memories of past events, yet the precise relationship between bodily self-consciousness and memory formation, especially in real-life contexts, remains a topic of ongoing research. The present study investigated the relationship between bodily self-...

Introduction. – Although frequently observed in neurological disorders, social-cognitive deficits, which contribute to social behavior dysfunction, remain poorly assessed in clinical neuropsychology. A new task has been developed to better screen for these deficits. Objectives. – REALSoCog was used in two case studies (SL, 41-years-old, severe head...

This paper provides new research perspectives in the field of multimodal comprehension (auditory crossing visual information) by using immersion and incorporating eye tracking in a virtual reality environment. The objective is to investigate the influence of a change in narrative perspective (point of view) during the activation of a mental model u...

Although previous studies have suggested that some component processes of social cognition decline in normal aging, several methodological limitations can be pointed out. Traditional sociocognitive tasks assess processes separately and lack ecological validity. In the present study, the main aim was to propose an integrative social cognition assess...

The recall of factual and contextual information and its related binding is a core characteristic of episodic memory sensitive to aging effects. Context and binding may also be significantly involved in the production of false memories. The innovative aim of the present study was to assess in a naturalistic context the quantity and quality of corre...

Nous souhaitons valider un nouveau programme Serious Games de stimulation cognitive sur tablette tactile visant la mémoire (épisodique, prospective, visuospatiale) et l'apprentissage de procédures d'optimisation de l'encodage (traitement exécutif et attentionnel, imagerie mentale, référence à soi, motivation). Merci de diffuser cette annonce aux pe...

Using virtual reality, we implemented a naturalistic variant of the DRM paradigm in young and older adults to evaluate false recall and false recognition. We distinguished false recognition related to the highest semantic association (the critical lures), semantic similarity (i.e. items that belong to the same semantic category), and perceptual sim...

Management of travelers' cognitive load is crucial for efficient information processing for optimal railway operations. We investigated variations in travelers' cognitive load with different expertise levels, in a field study. We aimed to assess the use of three eye metrics: pupil diameter, saccade amplitude and gaze of fixation duration for cognit...

An extensive psychological literature shows that sleep actively promotes human episodic memory (EM) consolidation in younger adults. However, evidence for the benefit of sleep for EM consolidation in aging is still elusive. In addition, most of the previous studies used EM assessments that are very different from everyday life conditions and are fa...

Recent theories in the field of embodied cognition have pointed out the role of the body for episodic memory, i.e. the memory for personally experienced events. Although virtual embodiment has been used traditionally to investigate the different components of bodily self, it provides great advantages to manipulate the whole embodied experience. In...
