Abstract
This study sought to determine if there was a duration of location which optimized recall of linear positioning. Measures analyzed were constant, variable, and absolute error. Four groups (n = 10) performed a 30-cm linear positioning task, remaining at the criterion end location for 0, 2, 5, or 10 sec. No significant differences for constant and variable errors were found for any of the manipulated location durations. However, absolute error for the 10-sec. duration was significantly greater than each of the other durations. It was concluded that location duration has not been a confounding factor in linear positioning studies and a location duration of 2 sec. is suggested as the most suitable for positioning studies.
