Examining Negativity Biases in Facial Emotion Reactions in Young Persons First Presenting with Borderline Personality Disorder

These data provide initial evidence that negatively biased emotional expression, when responding with negative facial expressions to neutral, happy, or angry faces, is not evident in young persons first presenting to a specialist outpatient service for treatment of BPD. However, a bias may be demonstrated by what appears to be a slower positive affective response to happy faces. The implications of these findings are discussed, particularly in relation to factors associated with chronicity of illness that might potentially contribute to the development of a more pronounced negativity bias later in the course of the illness. We encourage further examination of negativity biases in the developmental sequelae of BPD via longitudinal design or cross-sectional designs that include BPD participants across the course of illness, as well as further research to explore the possibility that positive affective reactions in this group might not be grossly blunted but rather delayed.
