Self–other distinction (SOD) refers to the ability distinguish one’s own body, actions, and mental representations from those of others. Problems with SOD are considered be a key feature borderline personality disorder (BPD). However, empirical studies on in BPD scarce. Here, we present study providing preliminary support for usefulness validity self–other facial morphing task capture capacity sample nonclinical participants high (n = 30) low 32) features. Participants had watch video sequence which their face was gradually morphed into an unfamiliar other (self-to-other) or vice versa (other-to-self), requiring them indicate at point they judged morph look more like target than starting face. Consistent predictions, results showed that high-BPD group themselves longer self-to-other direction (suggestive egocentric bias), but only relatively attractive In other-to-self direction, difficulty recognizing (i.e., altercentric this time less Further research is needed replicate these findings clinical samples, overall suggest current might suited investigate problems BPD.
