The purpose of this study was to investigate affective changes through EEG asymmetry when subjects run around each curved track, counterclockwise (CCW) and clockwise (CW). A total of 20 (10 females and 10 males; M age=20.5) subjects, all of whom were right-handed, participated in the study. According to different directional conditions, all subjects were randomly divided into two groups which were CCW and CW, and the gender ratio was definitely considered as the same. Using the motor imagery (MI) task, they were instructed to start MI when presented with a dynamic image showing the first person view of running a curved track in either direction for 1800ms. The frontal (Fp2-Fp1, F4-F3) and central (C4-C3) lobes of each subject were measured while they were performing MI. The independent t-test was conducted to determined differences in the alpha values between directional conditions. As a result, there was a significant difference in the frontal lobe (F4-F3) between conditions. Especially, subjects in the CW condition displayed greater right frontal activity (F4), while greater l eft f rontal activity (F3) was observed in the CCW condition. It means that running around a t rack counterclockwise is predictive of greater left frontal activity which indicates more positive affect while running around a track clockwise is expected to be greater right frontal activity which can be interpreted in association with negative affect. In conclusion, the result of this study demonstrated that affective changes can be appear depending on different directional conditions and then be closely associated to the formation of turning bias.
