Abstract

The purpose of this study was to evaluate the effect of Handedness and Task Difficulty on behavioral and neural components of speed-accuracy trade off. The study was a Quasi-experimental research and focused on fundamental research. The participants of this study consisted of 20 students aged 14 and 15 years old. The instrument was four channel EEG, optical sensor with sensor, laptop, metronome, and Target-Tapping-Test software. Given the Edinburgh Handedness questionnaire scores, participants were divided into two left-hand and right-hand groups. They performed the simple and difficult tasks in a 30s with dominant and non-dominant hands. At the same time, the behavioral output as output digits from the pen and tablet (spatial and temporal errors) and the EEG data from the brain regions. For data analysis, repeated measures ANOVA was used at the significance level of 0. 05. The results showed that non-dominant limb is affected to the Task Difficulty than dominant hand, and has more spatial error. The Handedness and Task Difficulty had no significant effect on the effective width of the target. In the non-dominant limb, the average interruption for difficult task was more than simple task. In the C3 region, the gamma wave power was higher in a difficult task than in an easy task, and in right-handed subjects was higher in the hand. In the F4 area, the power of the alpha wave was easy for left-hand people when performing difficult moves above the task. Seems, in tasks that require accuracy and speed, spatial and temporal errors are affected by the Task Difficulty and Handedness, But the timing errors is more affected by the Task Difficulty than the Handedness. It also seems that the left and right frontal lobe areas are more important than other areas in Fitz's Task execution.
