Time is overestimated in obesity: A cohort study

Area of Science:

• Neuroscience
• Psychology
• Behavioral Science

Background:

• Obesity is frequently associated with food addiction and high impulsivity.
• Individuals with a history of impulsivity or drug addiction often exhibit time overestimation.
• Understanding cognitive biases in obesity is crucial for developing effective interventions.

Purpose of the Study:

• To investigate whether obese individuals overestimate the duration of visual stimuli.
• To explore the potential link between obesity and temporal perception deficits.

Main Methods:

• A timing task involving visual stimuli was administered to 92 obese participants and 182 healthy controls.
• Participants were asked to estimate the duration of presented visual stimuli.
• Statistical analyses were performed to compare duration estimations between groups.

Main Results:

• Obese participants significantly overestimated the duration of visual stimuli compared to healthy controls.
• This finding supports the hypothesis that temporal overestimation is present in obesity.
• The results indicate a potential cognitive dysfunction related to time perception in obesity.

Conclusions:

• Obesity may be associated with an overestimation of time duration.
• This temporal perception deficit could play a role in the development and maintenance of obesity-related behaviors.
• Further research into cognitive dysfunctions in obesity is warranted for clinical applications.
