High dissociators report more executive function difficulties, but objective tests show no performance difference. This suggests subjective perceptions of impairment in dissociation may not reflect actual cognitive deficits.

Area of Science:

  • Neuroscience
  • Psychology
  • Cognitive Science

Background:

  • Dissociation is known to impact cognition, yet neuropsychological examination is limited.
  • Executive functions are crucial cognitive processes often affected in dissociative disorders.

Purpose of the Study:

  • To investigate the relationship between self-reported and objectively measured executive function in individuals with high versus low dissociation.
  • To explore whether subjective experiences of executive difficulties align with objective neuropsychological performance.

Main Methods:

  • Compared 33 high and 32 low dissociators using the Dissociative Experiences Scale.
  • Utilized self-report (Dysexecutive Questionnaire) and neuropsychological tests (Iowa Gambling Task, Operation Span, Wisconsin Card Sorting Test-64) for executive function assessment.

Main Results:

  • High dissociators reported significantly more executive difficulties than low dissociators.
  • No significant differences in objective performance on neuropsychological measures of executive function were found between high and low dissociators.
  • Self-reported executive difficulties in high dissociators were not correlated with their performance on objective tests.

Conclusions:

  • Subjective perceptions of executive impairment in individuals with high dissociation may be distinct from objective cognitive deficits.
  • This discrepancy highlights a potential mechanism underlying the clinical presentation of dissociation.
  • Findings underscore the importance of integrating subjective and objective measures in understanding dissociative phenomena.
