Emotional correlates of fluency test and maze performance

Area of Science:

• Neuropsychology
• Clinical Psychology

Background:

• Executive functions are crucial cognitive processes.
• Psychiatric conditions like depression and anxiety can impact cognitive performance.
• The relationship between specific MMPI-2 scales and executive functions requires further elucidation.

Purpose of the Study:

• To investigate the relationship between depression, anxiety, and thought content, and executive functioning.
• To test the hypothesis of a negative correlation between MMPI-2 scales and executive function measures.
• To examine how specific MMPI-2 scales relate to performance on verbal fluency and visuospatial tasks.

Main Methods:

• Correlational analyses were conducted on 70 male psychiatric patients.
• MMPI-2 scales (D, PT, Anxiety, Fears, Obsessional Thinking, Depression, Bizarre Mentation) were used.
• Executive functioning was assessed using the Controlled Oral Word Association Test (FAS), Design Fluency, and WISC-R Mazes.

Main Results:

• Fluency and maze performance showed independence from depression (D, DEP) and bizarre mentation (BIZ) scores.
• A mild association was found between generalized anxiety (ANX) and executive function measures.
• A strong negative relationship emerged between fearfulness (FRS) scores and executive functioning.

Conclusions:

• Fearfulness, as measured by the MMPI-2, significantly impacts executive functions.
• Depression and bizarre thought content appear less influential on these specific cognitive abilities.
• Findings highlight the nuanced relationship between psychological distress and cognitive performance.
