Memory capacity as the core mechanism of the development of space-time interferences in children.

This study investigated the development of spatiotemporal perceptual interactions in 5-to-7 years old children. Participants reproduced the temporal and spatial interval between sequentially presented visual stimuli. The time and spacing between stimuli were experimentally manipulated.

Cognitive and plastic recurrent neural network clock model for the judgment of time and its variations.

The aim of this study in the field of computational neurosciences was to simulate and predict inter-individual variability in time judgements with different neuropsychological properties. We propose and test a Simple Recurrent Neural Network-based clock model that is able to account for inter-individual variability in time judgment by adding four new components into the clock system: the first relates to the plasticity of the neural system, the second to the attention allocated to time, the third to the memory of duration, and the fourth to the learning of duration by iteration. A simulation with this model explored its fit with participants' time estimates in a temporal reproduction task undertaken by both children and adults, whose varied cognitive abilities were assessed with neuropsychological tests.

How physical activity and passion color the passage of time: A response with ultra-trail runners.

The aim of this study was to replicate the results of a lengthening effect caused by physical activity already observed in duration length judgment, using the time passage judgment measure, while exploring the effects of passion types (obsessive vs. harmonious) on time perception. A total of 378 ultra-trail runners responded to an online questionnaire in which the type of passion and the passage of time (PoT) judgments associated with both an ultra-trail context and a non-trail daily context were collected.

The timing database: An open-access, live repository for interval timing studies.

Interval timing refers to the ability to perceive and remember intervals in the seconds to minutes range. Our contemporary understanding of interval timing is derived from relatively small-scale, isolated studies that investigate a limited range of intervals with a small sample size, usually based on a single task. Consequently, the conclusions drawn from individual studies are not readily generalizable to other tasks, conditions, and task parameters.

The relationships between social media exposure, food craving, cognitive impulsivity and cognitive restraint.

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 in young adults continues to grow.

Effect of food cues on time perception: influence of calories and diet control.

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 pictures. In a second experiment, 102 participants performed a strict replication of Experiment 1, without the low-calorie pictures condition as it showed less pronounced effects.

When Dogs Shrink the Typical Lengthening Effect Caused by Negative Emotions.

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 second experiment, students were randomly assigned to one of the three waiting groups (waiting alone, with another person, or with a dog) before being confronted with the temporal bisection task.

Simultaneous time processing in children and adults: When attention predicts temporal interference effects.

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. In a first experiment, two or three durations were presented with a synchrony of their onset.

Time contraction caused by a distractor in children and adults: The influence of inhibition capacities.

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 600 ms) from a long one (1500 or 2400 ms). They had then to decide whether intermediate stimulus duration was more similar to the short or to the long standard duration.

The dynamic effect of context on interval timing in children and adults.

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 task with a short and a long duration distribution.

Differences in modal distortion in time perception due to working memory capacity: a response with a developmental study in children and adults.

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 the visual stimuli.

High levels of time contraction in young children in dual tasks are related to their limited attention capacities.

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 time contraction in a dual-task condition is greater in younger children and, if so, whether this is specifically related to their limited attention capacities.
