Preliminary investigation of emotional sensitivity and lie-detection abilities in individuals with features of Borderline Personality Disorder
I recruited 60 participants who had either low- or high- levels of symptoms of borderline personality disorder. They were shown a number of videos of people telling lies or the truth (about emotional and non-emotional topics), and their abilities at recognising facial emotions were also assessed.
People with high levels of BPD symptoms had greater severity of childhood trauma. People who were better at reading emotions were better at detecting when lies were being told, but this didn't differ between groups.
