The way we perceive time significantly influences our interactions with the world, including our eating behaviors. While eating disorders (EDs) are often studied through their cognitive and behavioral aspects, the role of temporal perception, particularly in connection with food stimuli, remains a relatively unexplored research area. Preliminary data suggest that time perception may be altered in individuals with, but also in non-clinical populations, highlighting the importance of understanding these
mechanisms beyond clinical diagnoses. These alterations in time perception could have a significant impact on eating behaviors, by affecting the ability to accurately assess hunger and satiety cues, and by contributing to a sense of loss of control. Consequently, these timing biases may reinforce and intensify the symptoms of EDs. The objective of this project is to examine these interactions in depth through four avenues: (1) quantifying the influence of real food stimuli on time perception at different temporal scales in a non-clinical adult population, (2) studying, through a longitudinal approach in young adolescents, whether time perception constitutes a cognitive vulnerability factor for the development of EDs, and how social influences modulate this relationship.
