In everyday life individuals are required to make decisions that bear a certain<br />
degree of uncertainty regarding potential gains and losses. Individuals<br />
differ with respect to their ability to adjust their choices and behavior in<br />
the face of higher risk.<br />
To investigate the neural systems mediating these differences, we presented<br />
healthy controls (n=13) and two groups of criminal offenders [11<br />
patients with psychopathy as defined by the Hare Psychopathy Checklist<br />
and 12 patients with DSM-IV borderline personality disorder (BPD)] with<br />
the Behavioral Investment Allocation Strategy task (Kuhnen &Knutson,<br />
2005) and monitored brain activity using fMRI. During this task, participants<br />
were required to choose between two stocks and a bond. At the<br />
beginning of an experimental block one of the two stocks was randomly<br />
assigned to be the “good” (+10 €) or the “bad” stock ( 10 €) without the<br />
participants´ knowledge. The bond always paid 1 Euro.<br />
When uncertainty which stock to choose was high (e.g., at the beginning<br />
of a block) controls showed adaptive risk-avoidant behavior (i.e.,<br />
were more likely to choose the bond). Chosing the bond in trials with high<br />
uncertainty was preceded by increased activity in a functional network<br />
including insula, inferior frontal gyrus (IFG), and pre-supplementary motor<br />
area. Uncertainty was represented in rostral anterior cingulate gyrus<br />
(rACC). Criminal offenders with BPD did not choose more bonds when<br />
uncertainty was high. This risk-seeking behavior was accompanied by less<br />
activity in IFG before choosing the bond in contrast to controls. Psychopaths<br />
only differed from controls by decreased activity in rACC reflecting a<br />
deficit to emotionally represent uncertainty.<br />
These results support the theory that criminal offenders with psychopathy<br />
are characterized by a lack of emotion, whereas criminal offenders with<br />
BPD show a more pronounced deficit in behavioral control to adjust their<br />
choices in the face of higher risk.
