The impact of social exclusion on “reading the mind in the eyes” performance in relation to borderline personality disorder features

In this study we used the Reading the Mind in the Eyes Test (RMET) to explore facial emotion recognition in borderline personality disorder (BPD). We also used Cyberball, a computerized task designed to mimic social ostracism, to examine the response of BPD-feature participants to social exclusion. Seventeen individuals with BPD features were compared to 16 healthy controls on RMET performance pre- and post-exclusion via Cyberball. Our results revealed a significant interaction between BPD-feature status and RMET performance in relation to neutral stimuli following a social exclusion experience. BPD participants’ ability to correctly identify neutral faces significantly decreased following exclusion. This finding suggests that once an individual with BPD features experiences a social exclusion event, his or her objectivity decreases and affective valence is ascribed to stimuli previously perceived as neutral. Our results may help to explain, in part, the social instability seen in BPD.
