Examining the relationship among flow, dart throw, and EEG activity Chin-Fong Kao, Tsung-Min Hung, Li-Chuan Lo, Ying-Jung Chen, Chiau-Ling Hung, Tse-Chuan Lin, Chia-Ling Li, The purpose of this study was to investigate the relationship among flow、dart throw, and EEG activity. Eighteen male college students (aged between 20~27 year old) that were trained at dart throw for a minimum of three months were recruited. Participants were required to perform 60 dart throws that were grouped into six blocks, ten darts each, on a standardized dart throw task. A Chinese version of Jackson and Marsh’s Flow State Scale (FSS) was administered to measure participant’s flow state after each block of dart throw. A median split was used to categorize participants into either high or low flow group. EEG was recorded at 28 scalp sites and EOG were also monitored. In addition, bipolar EMG was measured at a site 1/3 between wrist and shoulder to mark the onset of the throwing movement. The recorded EEG was segmented into four, 0.5 second each, epochs of the last 2 seconds prior to the initiation of movement. Cleaned EEG epochs were subjected to FFT. An independent t test confirmed that the flow scores were significantly different between these two groups (mean=107.95, SD=5.41 vs. mean=88.30, SD=6.30). Another independent t test also showed that participants in the high flow group performed slightly better (a score of 8.35 vs. 8.02) than that of low flow group. Although two separate independent t tests on the α ratio for the frontal and temporal asymmetry measures failed to find difference between these two groups, a 2×4×5 (group×time×area) ANOVA with the last two were treated as repeated measures on EEG α power resulted in a significant area main effect. Post hoc pairwise comparison showed that α power at anterior area was larger than that of posterior area. In conclusion, despite the small difference in performance, there was no difference on EEG asymmetry and temporal dynamics between groups.
