Subjectivity of time perception: a visual emotional orchestration

Area of Science:

• Cognitive Psychology
• Neuroscience
• Visual Perception

Background:

• Time perception is a complex cognitive function influenced by various factors.
• The role of emotional content in modulating visual time perception remains an active area of research.

Purpose of the Study:

• To investigate how visual emotional content affects the perception of time.
• To differentiate the influence of content-bearing versus content-deprived stimuli on duration reproduction.
• To examine the impact of stimulus valence (neutral, pleasant, unpleasant) on time perception accuracy and precision.

Main Methods:

• Participants reproduced durations (2, 4, 6 seconds) of either content-deprived (gray squares) or content-bearing (neutral, pleasant, unpleasant images from the International Affective Pictures Systems) stimuli.
• Comparison of reproduced durations and precision between stimulus types and across different durations.

Main Results:

• Content-bearing stimuli were overestimated at 2 seconds compared to content-deprived stimuli, with this effect diminishing at longer durations.
• Emotional (pleasant and unpleasant) stimuli were perceived as longer than neutral stimuli at 4 seconds.
• Temporal reproduction precision was lower for emotional stimuli than for non-emotional stimuli across all durations.

Conclusions:

• Visual content, particularly emotional content, significantly influences time perception.
• A dissociation exists in the content effect on visual timing: relative overestimation for all content at short durations and delayed overestimation for emotional content at intermediate durations.
• Emotion impacts both the accuracy (overestimation) and precision of time judgments, highlighting the need to integrate these aspects into time perception models.
