Expression and detection of triarchic psychopathy traits in the self-defining memories of U.S. undergraduates

Research linking psychopathic personality to autobiographical memory and narrative identity is limited. We present preliminary evidence suggesting that traits from the triarchic model of psychopathy (measured via self-report) predict self-reported affect as well as researcher-coded affective themes, event specificity, and meaning making in self-defining memories (SDMs). We observed this in a small sample that was well-powered for multilevel modeling (1200 SDMs total obtained from 120 undergraduate participants from the U.S.). Additionally, we present preliminary evidence – using an extreme-groups approach – that raters can detect the expression of the triarchic psychopathy traits in written SDM transcripts. Ten research assistants (working independently, and without prior training in assessment) used prototype descriptions of the triarchic traits to rate 40 participants on each trait. Their ratings correlated meaningfully with a range of relevant self-reported traits. Thus, aspects of psychopathy could be detected, albeit imperfectly, solely from written autobiographical memories. This research contributes to the literatures on person perception, psychopathy, and narrative identity. It also supports the status of autobiographical narratives as a unique source of data in personality research and clinical inference. •Psychopathy, particularly boldness and meanness, predicted shorter memory narratives.•Boldness predicted positive affect and emotional stability in self-defining memories.•Disinhibition predicted nonspecific and meanness – nonspecific, less meaningful SDMs.•Researcher-rated meanness in SDMs predicted self-reported psychopathy and meanness.•Researcher-rated triarchic traits in SDMs predicted self-reported trait constructs.
