This study found that combining the coin-in-the-hand test with the autobiographical interview can effectively identify individuals feigning memory impairment, distinguishing them from genuine memory-impaired patients and normal controls.

Area of Science:

  • Neuropsychology
  • Cognitive Psychology
  • Forensic Psychology

Background:

  • Differentiating genuine cognitive impairment from feigned impairment is crucial in clinical and forensic settings.
  • Malingering detection requires reliable and valid assessment tools.

Purpose of the Study:

  • To evaluate the efficacy of various tests in distinguishing simulated memory impairment from genuine memory deficits and normal performance.
  • To identify specific tests that can reliably detect malingering.

Main Methods:

  • A simulation design was employed where healthy participants were instructed to feign memory impairment.
  • These participants were compared against honest-performing normal controls and a group with acquired brain injury-induced memory impairment.
  • Fifteen different tasks were administered to all groups, with performance differences analyzed.

Main Results:

  • Simulators performed significantly differently from both normal and memory-impaired groups on 5 out of 15 administered tasks.
  • The combination of the coin-in-the-hand test and the autobiographical interview accurately identified 95% of simulators.
  • This combined approach did not misclassify any genuine memory-impaired or normal participants.

Conclusions:

  • The joint administration of the coin-in-the-hand test and autobiographical interview shows promise as a tool for detecting malingering in memory assessments.
  • These tests may aid clinicians in differentiating feigned memory loss from actual cognitive deficits.
