Negativity bias in false memory: moderation by neuroticism after a delay

Area of Science:

• Cognitive Psychology
• Social Psychology
• Neuroscience

Background:

• The negativity bias describes the tendency to focus more on negative information.
• Understanding this bias is crucial for explaining cognitive and emotional responses.
• Previous research has explored the negativity bias in various contexts.

Purpose of the Study:

• To investigate how the negativity bias affects correct and false recognition of negative versus positive words.
• To examine the moderating role of trait neuroticism on these memory effects.
• To explore the implications for mental health.

Main Methods:

• Utilized the Deese-Roediger-McDermott (DRM) illusory memory paradigm.
• Participants studied word lists composed of semantic associates of a critical lure.
• Lists contained either positive or negative words; recognition was tested immediately and after a 24-hr delay.

Main Results:

• Confirmed a negativity bias in correct recognition, with better recall for negative words.
• Immediate testing showed greater false memory for negative critical lures.
• After a delay, high neuroticism individuals showed greater false memory for negative lures, unlike low neuroticism individuals.

Conclusions:

• The negativity bias influences both correct and false memory.
• Trait neuroticism plays a significant role in modulating false memory for negative information over time.
• Findings have potential implications for understanding mental health disorders characterized by negative biases.
