Social Memory Biases and Borderline Personality Disorder Features: Relevance of Perceived Social Support

Area of Science:

• Psychology
• Clinical Psychology
• Social Psychology

Background:

• Poor relationship quality is prevalent in borderline personality disorder (BPD).
• Biased interpersonal decision-making may contribute to relationship difficulties in BPD.
• Memory biases in partner selection are under-explored in BPD.

Purpose of the Study:

• To investigate memory biases for hypothetical partners varying in familiarity among individuals with BPD features.
• To examine the moderating role of perceived social support on these memory biases.

Main Methods:

• Participants (n=192) completed partner choice tasks based on traits and a subsequent trait recognition task.
• The study involved two parts: vignette-based partner selection and delayed trait recognition.
• Measures included BPD features, perceived social support, and memory bias assessment.

Main Results:

• Lower perceived social support correlated with a bias favoring novel partners.
• BPD features showed a negative association with overall interpersonal memory bias.
• In individuals with low social support, BPD features were linked to a positive interpersonal memory bias.

Conclusions:

• Memory biases may influence partner selection in individuals with BPD features.
• Perceived social support plays a critical role in modulating these memory biases.
• Further research should explore the interplay between BPD, social support, and interpersonal memory.
