ABSTRACT

This study aimed to investigate the characteristic of adult ADHD by assessing the inhibition deficit in adult ADHD. That is, this study intended to examined whether primary symptoms of ADHD such as inattention, hyperactivity, and impulsivity continued until adulthood. Therefore, Adults ADHD were compared with controls using two neuropsychological experiment tasks. First, we used the modified Stroop task through eye-tracker. Stroop task is used to investigate adult ADHD with deficit through movement and control of attention. Later, we used the modified Stroop task and Priming-Stroop task to examine ADHD tendency concerning deficit of sustainable attention and response inhibition. As a result, lower response time was observed in ADHD tendency groups than in the control group. Beside, higher Stroop effect rate was observed in ADHD tendency groups than in the control group, and two groups had different response accuracy. That is, ADHD tendency groups responded too slowly and impulsively. This means that ADHD tendency groups had differences between them. These results show that ADHD tendency groups, compared to control group, had a difficulty in controlling attention and inhibition. We found that the ADHD tendency groups has impulsive and inattentive tendencies. The results of this study can be valuable in understanding the characteristic symptoms in adult ADHD tendency group. However, these results have some limitations and cannot be generalized to adult ADHD. Future studies, are necessary to generalize characteristics of adult ADHD by conducting tasks with other samples.
