The influence of self-referential stimuli on duration perception

Area of Science:

• Cognitive Psychology
• Neuroscience
• Social Psychology

Background:

• Subjective salience influences duration estimation.
• Self-referential stimuli hold significant biological and social importance.
• The impact of self-referential information on time perception remains understudied.

Purpose of the Study:

• To investigate how self-referential information affects duration perception.
• To explore the temporal bisection task's application in self-referential time estimation.
• To differentiate the effects of own name versus familiar/unfamiliar names on time perception.

Main Methods:

• Experiment 1: Temporal bisection task comparing duration estimation of own name vs. familiar/unfamiliar names.
• Experiment 2: Duration perception of self-referential vs. friend-referential personality-trait words.
• Utilized quantitative behavioral measures to assess time perception accuracy and sensitivity.

Main Results:

• Participants overestimated duration for their own name compared to stranger names.
• Increased sensitivity to duration perception was observed for self-referential stimuli.
• Self-referential negative trait words were perceived as longer than friend-referential negative trait words.

Conclusions:

• Self-referential information significantly alters duration perception, causing subjective time dilation.
• Increased attentional resource engagement is a potential mechanism for this time dilation effect.
• Findings suggest a role for self-knowledge maintenance in modulating temporal experiences.
