Region of Enrollment

Quality of motor behavior was indexed by the percentage of samples in which the participants were within the trained (i.e. optimal) trajectory. The trained trajectory was a 2cm wide channel in the shape of a half circle between two targets which were 25cm apart from each other. Therefore, the scale measure is a percentage which can range between 0 and 100%.

Quality of Motor Performance

Brain electrophysiology measure of attentional processes as indexed by high alpha power (10-13 Hz). The unit of measurement is a percentage as the amount of power (microvolts squared) in the high alpha band was divided by the total power in the spectrum (i.e. 1-50 Hz). This method is commonly employed to normalize the power of a particular frequency if the statistical design includes a between subjects factor.
