초록

Response complexity effect studies have consistently revealed slower reaction times with more complex movements. However, some researchers have questioned whether cognitive processing time is indeed extended by factors such as movement complexity and accuracy. The limb mass involved with movements could be a confound. Eye movements allow research on the same phenomenon without the confounding effect of body mass. The current study investigated the movement complexity effect of eye movements by using electrooculargram (EOG) which can overcome the sensitivity constraint of eye tracking system. Ten participants performed four different eye movement conditions (i.e., moving from a central focus position to a target located at the periphery). A movement complexity effect was identified. Two, three, and four saccadic eye movement conditions took longer to initiate than one saccade. this results confirmed that response complexity effect is responsible for processing time delay involved with response programing stage. Additionally, movement kinematics of first saccadic eye movement revealed that reversal saccadic eye movement with the same movement amplitude caused more efficient reorganization of motor program than single saccadic eye movement.
