Computer-based diagnostics and therapies curing attention deficit disorders are key components in neuropsychological rehabilitation. Due to the fact that hardly any studies seek to explore the effects of computer games on brain-damaged patients, the present work aims at demonstrating the possible influence of a neuropsychological training program (called Rehacom) and a computer game (Need for Speed) regarding concentration, divided attention and motivation for such a medical intervention on patients with brain-injury.The study was conducted on 17 patients who suffered a stroke and one patient with impaired brain activity. Altogether, there were two groups participating in the interventional program whereas the control group was without medical intervention. Each group consisted of 6 people. In more detail, alongside their usual therapeutical treatment, patients belonging to the first group (?computer game group?) were exposed to the computer game Need for Speed ten times in total with each session lasting for about twenty minutes. In the same manner, the second group (?Rehacom group?) performed the training program Rehacom while, in total contrast, the third group had no specific intervention (?control group?).In order to be able to measure changes in concentration, divided attention and motivation all groups had to do Go/Nogo and divided attention tests right before and after the investigation (prae- and posttest). Similarly, they were obliged to answer the scale of motivation elaborated by Andrews and Withey. The results of the study demonstrate that the computer game group and the control group showed significantly better reaction times in the posttest than in the praetest. In contrast, the Rehacom group displayed significantly slower reaction times in the posttest. But frequencies of errors do not differ between groups. In all groups divided attention showed significantly better performance in the posttest than in the praetest.
