Cross-situational consistency in recognition memory response bias.

Area of Science:

• Cognitive Psychology
• Memory Research
• Decision Making

Background:

• Individual differences in response bias (tendency to say "old" or "new") are common in recognition memory tests.
• Previous research suggested response bias might be a stable cognitive trait, but this was tested within a single experimental context.
• The current study aimed to determine if response bias remains stable across different experimental settings.

Purpose of the Study:

• To investigate the cross-situational stability of response bias in recognition memory.
• To explore whether response bias predicts performance on other cognitive tasks, such as eyewitness identification and go-no-go tasks.
• To examine potential relationships between response bias and personality traits.

Main Methods:

• Participants completed two recognition memory tests embedded in distinct experiments, separated by several weeks.
• Participants were unaware of any connection between the two experimental sessions.
• Response bias was measured in both sessions, and its predictive power for eyewitness memory and go-no-go task accuracy was assessed.

Main Results:

• Response bias demonstrated substantial stability across the two different experimental contexts.
• Response bias showed a weak but significant predictive relationship with eyewitness identification performance.
• Response bias also weakly predicted accuracy on a go-no-go task, but showed minimal correlation with five personality measures.

Conclusions:

• Response bias in recognition memory is a stable characteristic that generalizes across different experimental situations.
• This stable response bias appears to influence performance on other memory and decision-making tasks.
• Response bias represents a broadly influential cognitive characteristic of individuals.
