A performance-based measure of emotion response control: A preliminary MRI study

Area of Science:

• Neuroscience
• Psychology

Background:

• Emotion regulation is crucial for mood and neurological disorder studies.
• Performance-based assessments are needed to measure emotion regulation.
• Rorschach Inkblot Method's color and form responses are potential measures.

Purpose of the Study:

• To investigate the relationship between Rorschach color-form response discrepancies and cortical thickness.
• To explore the Rorschach Inkblot Method as a measure of emotion response control.
• To identify neural correlates of emotion regulation using the Rorschach.

Main Methods:

• Administered the Rorschach Inkblot Method to adults.
• Conducted structural MRI scans to measure regional cortical thickness.
• Analyzed the discrepancy between color (CF+C) and form (FC) responses.

Main Results:

• Greater middle frontal cortex thickness correlated with higher (CF+C)-FC scores, indicating less emotion response control (r=0.48, p<0.05).
• A moderate, non-significant correlation was found between middle frontal cortex thickness and the discrepancy score (r=0.42, p=0.07).
• Results support the Rorschach Inkblot Method's validity in assessing emotion response control.

Conclusions:

• The Rorschach Inkblot Method, particularly color-related variables, is a valid behavioral measure of emotion response control.
• Findings have implications for studying emotion regulation in mood disorders.
• Results inform future research design and power analyses for emotion regulation studies.
