Article
This study aimed to examine intra-individual differences in both duration and passage of time (PoT) judgments, and the relationships between them, for a wide range of durations going from a few hundred milliseconds to several minutes. Participants performed a study with a within-subjects design with durations in the milliseconds (200-400ms), second...

The aim of this study was to investigate the influence on individuals’ time perception of observing a range of foods differing in calorific content. In a first experiment, 92 adult participants performed a temporal bisection task with stimulus durations presented in the form of high- or low-calorie food pictures as well as matched non-food control...

Background: Young adults are increasingly exposed to social media and their image/video- based activities. They use these platforms to share images, videos and advice in different fields like food and nutrition with: recipe ideas, nutritional opinions or specific diets. Along with the rise of digital technologies, the prevalence of eating disorders...
Chapter
This chapter aims to synthesize the state of the art regarding the development of time perception in children.
Article
Research indicates that university students present higher levels of psychological distress compared with non-student age-matched youth. These levels are higher among healthcare students, and even higher during the Covid-19 pandemic. Therefore, cost-effective large-scale interventions are needed in order to prevent further development of psychologi...
Article
This paper examines how dogs can modulate the effects of emotion on time perception. To this end, participants performed a temporal bisection task with stimulus durations presented in the form of neutral or emotional facial expressions (angry, sad, and happy faces). In the first experiment, dog owners were compared with nondog owners, while in the...
Article
Full-text available
Children from 5 to 8 years of age, as well as adults, performed a temporal reproduction task in both a solo-timing condition and a multi-timing condition, with different durations presented simultaneously. In the multi-timing condition, all durations were processed because the participants did not know in advance which stimulus needed to be judged....
Article
The aim of this study was to examine the cognitive processes involved in time contraction caused by a non-temporal distractor during the presentation of a temporal stimulus. To this aim 95 children aged 5 to 8 years old as well as 25 adults were first trained to discriminate, on two visual temporal bisection tasks, a short standard duration (400 or...

The aim of this study was to identify the age at which parameters of timing performance in a temporal bisection task converge on an adult-like stable level. Participants in the 3- to 20-year-old range were tested using a temporal bisection task with sub-second and supra-second durations. Two samples were made based on these data. In the first sampl...
Article
Full-text available
This study tested the modality effect on time judgment in a bisection task in children and adults when auditory and visual stimuli were presented in the same session. Cognitive capacities of children and adults were assessed with different neuropsychological tests. The results showed a modality effect, with the auditory stimuli judged longer than t...
Thesis
Full-text available
Résumé : L’objectif de cette thèse est d’étudier le développement des conduites temporelles et leurs changements en fonction des contextes et des capacités cognitives des enfants, afin de proposer un modèle des distorsions du jugement du temps. Un ensemble de 9 études expérimentales ont été réalisées dans cette thèse s’inscrivant dans 3 axes princi...
Article
Full-text available
This study used a dual task with participants of different levels of cognitive capacities, assessed with neuropsychological tests, to examine the attentional cost on time judgment of processing concurrent temporal and non-temporal information. Children and adults performed a temporal reproduction task with either an interfering temporal or non-temp...
Article
Human reproductions of time intervals are often biased toward previously perceived durations, resulting in a central tendency effect. The aim of the current study was to compare this effect of temporal context on time reproductions within children and adults. Children aged from 5 to 7 years, as well as adults, performed a ready-set-go reproduction...
Article
Full-text available
This study investigated the ability of young children to embody other people's time in their time judgments. Children aged from 4 to 7 years had to learn target durations and to reproduce them with the presentation of static pictures of individuals whose posture or body shape suggested different body states (movement, movement with object, emotion,...
Article
Numerous studies have shown that durations are judged shorter in a dual-task condition than in a simple-task condition. The resource-based theory of time perception suggests that this is due to the processing of temporal information, which is a demanding cognitive task that consumes limited attention resources. Our study investigated whether this t...
Article
This paper provides a review of the literature on Near Death Experience (NDE). Several recurring features of the NDE, and their frequency, are presented. The issue of cultural variations of NDE being the subject of a debate, we chose to expose the data that support the cultural invariance hypothesis, but also those that reveal an impact of culture....
