| Outline of Final Research Achievements |
Enumeration of four or fewer objects is very fast and accurate, but gets slower and more error for more than four items. Generally the former is called subitizing and the latter is counting. In this study, we examined the electrophysiological correlates of subitizing and athletic performance for goaltender in ice hockey who is expected sustainable and wide-ranging attention. An electroencephalogram was recorded during enumeration task on visual arrays of ice hockey players in silhouette that varied in numerosity (3-6 and 7-12 silhouettes)and analyzed by using sLORETA(standardized low resolution brain electromagnetic tomography) to estimate the source characterization. The results demonstrated the increment of reaction time as a function of silhouettes, but goaltender performed more accurate estimate in numerosity than other players. The results of sLORETA showed increased activity in the ociipitoparietal network.
