High anxiety levels impair eyewitness performance under evaluative threat. Nonanxious individuals improved their performance, while anxious individuals performed at capacity due to worry.

Area of Science:

  • Psychology
  • Cognitive Psychology
  • Forensic Psychology

Background:

  • Individual differences in anxiety can affect cognitive performance.
  • Evaluative threat can influence performance on memory-dependent tasks.

Purpose of the Study:

  • To investigate the relationship between anxiety levels and eyewitness performance.
  • To examine the impact of evaluative threat during encoding and retrieval on eyewitness accuracy.

Main Methods:

  • Participants were categorized as high or low anxious based on the Test Anxiety Scale (TAS).
  • Anxiety-arousing instructions were administered during encoding and/or retrieval phases.
  • Eyewitness performance was assessed using a specific eyewitness task.

Main Results:

Related Experiment Videos

  • High-anxious subjects under evaluative threat at encoding and retrieval showed less accurate eyewitness performance compared to low-anxious subjects.
  • Performance differences were primarily due to improvements in nonanxious subjects, not debilitation in anxious subjects.
  • Low-anxious subjects demonstrated increased effort under threat, while high-anxious subjects performed at capacity due to worry.

Conclusions:

  • Anxiety significantly impacts eyewitness accuracy, particularly under conditions of evaluative threat.
  • High anxiety may limit working memory capacity due to task-irrelevant worry, hindering performance improvement.
  • Interventions to manage anxiety could potentially enhance eyewitness performance.
