CARDOSO, Caroline de Oliveira et al. Decision making in IGT: a case study of post-CVA of left versus right hemisphere. Psico-USF [online]. 2012, vol.17, n.1, pp.11-20. ISSN 2175-3563.  http://dx.doi.org/10.1590/S1413-82712012000100003.

This study aimed at conducting a comparative investigation of the decision-making process of two post-unilateral CVA adults as well as  verifying the role of hemispheric laterality in the performance of Iowa Gambling Task (IGT). One adult with right hemisphere damage (RHD) and another with left hemisphere damage (LHD), both following a subcortical ischemic post-CVA.  The IGT was used to evaluate the decision making. Patients had appropriate performance on the IGT suggesting a general good ability to make decisions. However, only the patient with LHD presented signs of ascendant learning curve. Conclusion: These data indicate that a subcortical lesion independent of the hemisphere may not influence on the IGT performance. It is suggested that comparative studies of groups should be conducted in order to compare patients with frontal and non-frontal lesions, helping to characterize the decision-making process in population with unilateral vascular damage.
