Confidence--accuracy relations for real and suggested events.

Area of Science:

• Cognitive Psychology
• Memory Studies
• Forensic Psychology

Background:

• The misinformation effect describes how post-event information can alter memory accuracy.
• Understanding the relationship between confidence and accuracy in memory is crucial, especially in legal contexts.
• Individual differences may influence how misinformation affects memory and confidence.

Purpose of the Study:

• To investigate the relationship between memory accuracy and confidence in the presence of misinformation.
• To examine how individual differences modulate the confidence-accuracy relationship for both accurate and misinformation-affected memories.

Main Methods:

• Participants underwent a misinformation procedure involving multiple events.
• Memory accuracy and self-reported confidence were assessed for both misinformation and non-misinformation items.
• Individual difference measures were collected and correlated with confidence-accuracy relationships.

Main Results:

• A significant difference was found in the confidence-accuracy relationship between misinformation and non-misinformation items.
• The confidence-accuracy relationship was weaker for items affected by misinformation.
• Several individual difference variables showed weak but significant correlations with the confidence-accuracy relationship.

Conclusions:

• Memory confidence is a less reliable indicator of accuracy when misinformation is present.
• Individual differences play a role, albeit a weak one, in how confidence relates to accuracy after exposure to misinformation.
• Findings highlight the complexities of memory, confidence, and suggest caution when relying on confidence as a sole indicator of memory accuracy in real-world scenarios.
