OXT and Borderline personality disorder: In contrast, Bertsch et al. (2018) observed a highly avoidant reaction to angry stimuli, while another study failed to replicate this finding (Schneider et al., 2020), However, Schneider et al. (2020) found that approach and avoidance were modulated by oxytocin administration, whereby oxytocin accelerated the avoidant response to angry faces relative to the approach condition toward happy facial expressions in patients with BPD.
