Mentalization, Oxytocin, and Cortisol in the General Population

Area of Science:

• Neuroscience
• Social Psychology
• Endocrinology

Background:

• Oxytocin and cortisol are implicated in social cognition and emotion regulation.
• Limited understanding of peripheral oxytocin and cortisol in social perception and mentalization in the general population.

Purpose of the Study:

• To investigate the relationship between peripheral oxytocin and cortisol levels and social perception (biological motion detection) and mentalization abilities.
• To explore correlations between mentalization, emotion intensity, and biological motion detection.

Main Methods:

• Assessed 150 healthy adults from the general community.
• Utilized a mentalization questionnaire and a scale for positive/negative emotion intensity.
• Measured salivary oxytocin and cortisol levels.
• Included biological motion detection tasks.

Main Results:

• Salivary oxytocin levels, but not cortisol, predicted mentalization abilities.
• Biological motion detection also predicted mentalization abilities.
• Found positive correlations between mentalization and positive emotions, and between mentalization and biological motion detection.

Conclusions:

• Oxytocin, independent of cortisol, plays a significant role in both low-level social perception and higher-level self-reflective mentalization.
• Findings suggest oxytocin's involvement in the foundational aspects of social cognition.
