ABSTRACT
Little is known about the impact of feedback on the reaction times (RTs) of brain-damaged (BD) patients. The authors therefore investigated the effect of positive and negative feedback on these patients, using a 4-choice RT task. Participants were 107 BD patients with different etiologies and 50 orthopedic (OG) control patients. Patients were assigned to 3 groups in which performance-independent negative, positive, and no feedback were given. Statistical analysis showed that negative feedback led to significantly shorter RTs in BD patients. Even BD patients with high depression scores were affected by negative feedback. In contrast, negative feedback had no impact on the RTs of the OG controls, and positive feedback had no influence on the RTs of any group. These results raise some interesting questions about motivational processes in BD patients.
