TY - JOUR PY - 2002// TI - Risky decisions and response reversal: is there evidence of orbitofrontal cortex dysfunction in psychopathic individuals? JO - Neuropsychologia A1 - Mitchell, Derek G. V. A1 - Colledge, E. A1 - Leonard, A. A1 - Blair, R. J. R. SP - 2013 EP - 2022 VL - 40 IS - 12 N2 - This study investigates the performance of psychopathic individuals on tasks believed to be sensitive to dorsolateral prefrontal and orbitofrontal cortex (OFC) functioning. Psychopathic and non-psychopathic individuals, as defined by the Hare psychopathy checklist revised (PCL-R) [Hare, The Hare psychopathy checklist revised, Toronto, Ontario: Multi-Health Systems, 1991] completed a gambling task [Cognition 50 (1994) 7] and the intradimensional/extradimensional (ID/ED) shift task [Nature 380 (1996) 69]. On the gambling task, psychopathic participants showed a global tendency to choose disadvantageously. Specifically, they showed an impaired ability to show learning over the course of the task. On the ID/ED task, the performance of psychopathic individuals was not significantly different from incarcerated controls on attentional set-shifting, but significant impairments were found on response reversal. These results are interpreted with reference to an OFC and amygdala dysfunction explanation of psychopathy.
