The Borderline Bias in Explicit Emotion Interpretation

Area of Science:

• Psychology
• Neuroscience
• Psychiatry

Background:

• Atypical emotion interpretation is common in individuals with borderline personality disorder (BPD), but findings are inconsistent.
• Fear of rejection and abandonment may bias emotion interpretation in BPD, particularly for moral emotions (anger, disgust, contempt).

Purpose of the Study:

• To investigate if individuals with BPD (iBPD) correctly interpret moral emotions related to social rejection.
• To examine if iBPD attribute more negative valence to these emotions compared to healthy controls.

Main Methods:

• 28 inpatient iBPD and 28 healthy controls judged static and dynamic facial expressions.
• Participants assessed emotions, valence, and self-reported arousal.
• Analyses controlled for alexithymia and anxiety levels.

Main Results:

• iBPD correctly interpreted unambiguous moral emotions (anger, disgust, contempt).
• iBPD demonstrated superior recognition of contempt compared to controls.
• iBPD judged all negative emotions more negatively than controls, with no differences in neutral or positive emotions.

Conclusions:

• Findings partially support the hypothesis that iBPD exhibit distinct emotion interpretation patterns.
• iBPD's ability to interpret moral emotions may be linked to their fear of rejection.
• Emotional valence perception is biased towards negativity in iBPD.
