Obsessive-compulsive tendencies predict reduced access to affective reactions to auditory stimuli

Area of Science:

• Psychology
• Neuroscience
• Psychiatry

Background:

• The Seeking Proxies for Internal States (SPIS) model suggests reduced access to internal states contributes to Obsessive-Compulsive Disorder (OCD).
• Previous research indicates a link between obsessive-compulsive tendencies and difficulties in accessing internal states.

Purpose of the Study:

• To provide further empirical support for the SPIS model.
• To investigate the association between obsessive-compulsive tendencies and the perception of affective internal states.

Main Methods:

• 170 participants completed a measure of obsessive-compulsive tendencies.
• Participants rated their emotional responses to 60 auditory stimuli.
• Emotional ratings were compared to normative valence ratings to assess perception accuracy.

Main Results:

• Higher obsessive-compulsive tendencies correlated with greater deviations between personal and normative emotional ratings.
• This effect was observed for both positive and negative auditory stimuli.
• Increased obsessive-compulsive tendencies predicted a less precise perception of affective internal states.

Conclusions:

• The findings support the SPIS model by demonstrating reduced attunement to affective internal states in individuals with higher obsessive-compulsive tendencies.
• This study highlights a potential mechanism in OCD related to emotional processing deficits.
• The results suggest that auditory stimuli perception accuracy is impaired with increased obsessive-compulsive traits.
