Memory conformity for high-confidence recognition of faces.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Social Psychology

Background:

• Memory conformity describes how individual memory judgments are influenced by others.
• The impact of memory conformity on the accuracy-confidence relationship, especially for high-confidence judgments, remains unclear.
• Understanding these effects is crucial for assessing the reliability of eyewitness testimony and memory recall.

Purpose of the Study:

• To investigate whether memory conformity affects the accuracy-confidence relationship.
• To determine if memory conformity impacts the accuracy of high-confidence memory judgments.
• To explore differential effects of memory conformity on judgments of "new" versus "old" items.

Main Methods:

• Three experiments were conducted using face recognition tasks.
• Participants made recognition and confidence judgments after viewing responses from a fictional participant.
• Invalid responses (26%) from the fictional participant were systematically introduced.

Main Results:

• Exposure to another's memory judgments, even invalid ones, decreased high-confidence accuracy for both "old" and "new" facial recognition.
• Confidence-accuracy characteristics (CAC) analysis showed invalid responses disproportionately affected confidence assignments for "new" items.
• Memory conformity demonstrated distinct effects on confidence assignment for "new" versus "old" memory judgments.

Conclusions:

• Memory conformity significantly impacts high-confidence memory accuracy.
• Invalid social cues in memory tasks can reduce the reliability of confident recollections.
• The influence of memory conformity on confidence assignment differs between judgments of novel and previously encountered information.
