Abstract:
Depression and borderline personality disorder (BPD) are both thought to be accompanied by alterations in the subjective experience of environmental rewards. We evaluated responses in women to sweet, bitter and neutral tastes (juice, quinine and water): 29 with depression, 17 with BPD and 27 healthy controls. The BPD group gave lower pleasantness and higher disgust ratings for quinine and juice compared with the control group; the depression group did not differ significantly from the control group. Juice disgust ratings were related to self-disgust in BPD, suggesting close links between abnormal sensory processing and self-identity in BPD.
