Clinical experience has shown that patients performing the Grooved Pegboard Test have difficulty maintaining the manualized right-to-left placement strategy with their left hand. This study sought to investigate possible differences in placement time on the Grooved Pegboard task between participants using the standardized left hand approach and a reversed manualized left hand placement strategy (i.e., left-to-right). The participants included 63 male and female undergraduate volunteers between the ages of 18 and 25 years. All participants had no history of neurologic disease/trauma, or conditions that would affect motor functioning of the right and left upper extremities. Data were analyzed using a 3-way mixed-design ANOVA. Results revealed a significant main effects for gender (F(1, 59) = 5.215, p = .026) and handedness (F(1, 59) = 6.362, p = .014). Of primary interest was the main effect for placement direction, which was not significant, F(1, 59) = .120, p = .731. No significant interaction was observed (all p > .40). Recommendations for the use of this test in applied neuropsychological settings are offered.
