We investigated the relationship between pegboard test and P300. Subjects were twenty non-demented subjects with a mean age of 68.9±3.0 years, and were divided on the basis of pegboard test time into high performance (HP) group (n=7), middle performance (MP) group (n=7), and poor performance (PP) group (n=6). The P300 latencies and amplitudes, a different pattern midline sites (Pz, Cz, and Fz), were measured while they performed an Eriksen flanker task. Moreover reaction time (RT) and EMG-RT were measured. The results indicated that, 1) the HP group exhibited faster RT, EMG-RT on Eriksen flanker task, compared to the MP and PP groups, 2) in P300 latencies Pz, Cz, and Fz were significantly shortened in the HP group compared to the PP group, but no difference was found in amplitudes in any sites, 3) pegboard test was significantly correlated to the EMG-RT and P300 latency. These results suggest that pegboard test may reflect cognitive processing system including stimulus-evaluation time within the brain, in addition to the reaction processing system. Therefore, the pegboard test could be a useful tool for assessing cognitive function in older adults.
