Enhanced memory for negative social information in borderline personality disorder

Area of Science:

• Cognitive psychology
• Clinical psychology
• Social neuroscience

Background:

• Biased social cognition towards negative information can destabilize relationships.
• Interpersonal dysfunctions are key in understanding mental disorders like borderline personality disorder (BPD).

Purpose of the Study:

• To experimentally investigate enhanced memory retrieval of negative social information in BPD patients.
• To explore the association between this memory bias and BPD severity, rejection expectancies, and social detachment.

Main Methods:

• A novel looking-at-nothing paradigm was used to test memory retrieval.
• 45 BPD patients and 36 healthy women learned positive and negative personality traits.
• Behavioral memory performance and eye gaze patterns were analyzed.

Main Results:

• BPD patients demonstrated more accurate retrieval of negative person attributes compared to healthy controls.
• A negativity bias in social cognition was confirmed in the BPD sample.
• The negativity bias correlated with BPD severity, rejection expectancies, and social detachment.

Conclusions:

• Enhanced retrieval of negative social information may stem from dysfunctional cognitive schemas and reduced trust.
• This cognitive bias is relevant for understanding interpersonal difficulties in mental disorders.
• No differences in eye fixation behavior were observed between groups.
