EEG Measures of Alternative Strategies Used by Subjects to Solve Block Designs

Abstract
Human subjects (21) performing block designs were videotaped while simultaneous EEG measures were recorded. Blind raters classified each 10 s videotape sample into 1 of 5 categories for strategy of approach to the block design task. Subsequent correlations were obtained between rated strategy of approach and EEG measures. Strategies differed in amount of right hemisphere alpha activity present, indicating varying amounts of right hemisphere involvement, depending on the strategy employed.
