A Possible Link between Supra-Second Open-Ended Timing Sensitivity and Obsessive-Compulsive Tendencies.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Clinical Psychology

Background:

• Obsessive-compulsive disorder (OCD) is characterized by persistent uncertainty.
• Uncertainty in OCD may stem from altered access to internal bodily states.
• Supra-second timing is linked to interoceptive awareness and bodily signals.

Purpose of the Study:

• To investigate the relationship between supra-second temporal perception and obsessive-compulsive (OC) tendencies.
• To determine if supra-second timing deficits are specific to OCD or related to general anxiety and depression.

Main Methods:

• Sixty university students completed supra-second (~9 s) and sub-second (~450 ms) timing tasks, including fixed and open-ended supra-second conditions.
• Control non-temporal perceptual tasks were administered.
• Symptoms of OCD, depression, and anxiety were assessed using validated questionnaires.

Main Results:

• Open-ended supra-second temporal sensitivity significantly correlated with OC tendencies, even after controlling for depression and anxiety.
• Fixed supra-second and sub-second timing tasks, as well as control tasks, did not show significant correlations with OC tendencies.
• Higher OC tendencies were associated with reduced sensitivity in supra-second timing, requiring larger duration differences for discrimination.

Conclusions:

• Open-ended supra-second temporal estimation may be impaired in individuals with higher OC tendencies.
• These findings suggest that difficulties in estimating durations in real-life scenarios could be a feature of OCD.
• Further research is needed to confirm these results and explore the underlying mechanisms linking interoception, timing, and OCD.
