Lenzenweger currently maintains two broad programs of experimental psychopathology research. The first concerns schizotypy and schizophrenia and the second concerns the longitudinal study of severe personality disorders. In the schizotypy/schizophrenia program he conducts studies of sustained attention, working memory, eye movements, motor performance, and somatosensory perception in relation to schizotypic psychopathology. In the personality disorders research program, he is currently conducting analyses of multiple waves of personality disorder, personality, and temperament data gathered through the landmark NIMH-funded Longitudinal Study of Personality Disorders. He also studies borderline personality disorder from both a neurocognitive and neurobehavioral (i.e., neurobiological) perspective. He uses a variety of measurement approaches in the laboratory, including basic perception and cognitive tasks as well as psychometric methods.
