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...

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...

Although it is now well-known that self-reference processing benefits the episodic memory of laboratory material, studies have rarely investigated its influence on memory for specific episodes in a naturalistic context. We immersed 64 healthy young participants who were personally either very familiar or unfamiliar with the Latin Quarter of Paris i...

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...

Objective: Research suggests that prospective memory (PM) is impaired from the very early stages of Alzheimer’s disease (AD). We sought to further characterize this impairment in patients with mild AD, using a virtual reality (VR) task to provide ecological assessment of PM. Methods: Fifteen cognitively normal older individuals (76.47 years old ± 4...

Infant's manual laterality and eye-hand coordination emerge during the second part of the first year of life with the development of reaching. Nevertheless, little is known about the potential asymmetric characteristics of this coordination. The aim of this study was to describe visuo-spatial exploration in 6-month-old infants during reaching, acco...

Objective: This study was designed to improve our understanding of prospective memory (PM) changes in ageing, and to identify the cognitive correlates of PM decline, using a virtual environment, to provide a more realistic assessment than traditional laboratory tasks. Design: Thirty-five young and 29 older individuals exposed to a virtual town were...

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...

The aim of this study was to investigate auditory-visual temporal asynchrony in preterm infants using a habituation procedure coupled with an eye-tracking system in order to examine visual behavior accurately and determine specific visual areas of interest. Infants were habituated with an auditory-visual synchronic situation: a visual ball bounced...

Cognitive deficits in schizophrenia impair everyday functioning and instrumental daily living activities. These disabilities can be partly responsible for chronicity and institutionalization. We present here a virtual reality (VR) tool in which patients with schizophrenia performed a virtual game in an imaginary town during a three-month program. I...

The majority of episodic memory (EM) tests are far removed from what we experience in daily life and from the definition of this type of memory. This study examines the developmental trajectory of the main aspects of episodic memory — what, where, and when — and of feature binding in a naturalistic virtual environment. A population of 125 participa...

This study investigates the development of landmark and route knowledge in complex wayfinding situations. It focuses on how children (aged 6, 8, and 10 years) and young adults (n = 79) indicate, recognize, and bind landmarks and directions in both verbal and visuo-spatial tasks after learning a virtual route. Performance in these tasks is also rela...

None of the previous studies on aging have tested the influence of action with respect to the degree of interaction with the environment (active or passive navigation) and the source of itinerary choice (self or externally imposed), on episodic memory encoding. The aim of this pilot study was to explore the influence of these factors on feature bin...

Available tools for the assessment of Prospective Memory (PM; remember to execute an intention at an appropriate time, i.e., what and when, in the future) have been criticized. In fact, laboratory paradigms lack of ecological validity while evaluation in natural settings lack of experimental control. Virtual Reality (VR) circumvents those biases an...

The aim of this study is to broaden our understanding of the construction and early decline of spatial mental representations in route learning, considering the extent to which spatial ability and age-related differences in environment learning interact. The experiment examines spatial mental representation derived from taking a realistic route acq...

An experiment was run to complete our understanding of the involvement of working memory (WM) components in the construction of a spatial model from visual input, considering some of the visuospatial abilities known to modulate performance. In addition, to allow for consideration of the flexibility of the spatial representation, routes in a virtual...

A range of empirical findings suggest that active learning is important for memory. However, few studies have focused on the mechanisms underlying this enactment effect in episodic memory using complex environments. Research using virtual reality has yielded inconsistent results. We postulated that the effect of action depends on the degree of inte...

Virtual Reality (VR) is a very relevant tool for the study of complex cognitive functions, such as Prospective Memory (PM; remember to execute an intention at an appropriate time in the future). Thirty-five young subjects performed a PM task while immersed in a virtual city. On a theoretical level, we reached a better characterisation of PM functio...

Previous studies have shown that a saccade is coded in a specific reference frame according to its goal: to aim for a new object or to explore an object which has already been fixated. In a two saccade sequence, the second saccade aiming for a new object is programmed in a retinocentric reference frame in which the spatial location of the second ob...

When saccade amplitude is systematically inadequate relative to the desired target position, the saccadic system adaptively modifies the amplitude of subsequent saccades so as to recover precise targeting capabilities. The effect of saccadic adaptation on saccade metrics (amplitude, direction) is well documented, but the effect on dynamics (velocit...
