  • Title: Influences of handedness and gender on the grooved pegboard test.
    Author: Schmidt SL, Oliveira RM, Rocha FR, Abreu-Villaça Y.
    Journal: Brain Cogn; 2000 Dec; 44(3):445-54. PubMed ID: 11104536.
    Abstract:
    We studied performance on the Grooved Pegboard Test upon repeated trials and transfer of training between the hands in the first trial. The classification of handedness was based on the writing hand. We employed three trials for each hand and two different protocols for the order in which the hands started the test. For the three trials combined, women were faster than men. From the first to the second trial, there was an improvement in performance for both sexes. Within the first trial, sex differences reached significance and the protocol interacted with handedness. In this trial, only left-handed men were found to benefit from previous opposite-hand performance. It is speculated that a larger corpus callosum in left-handed men allows for the greater transfer of training between the hands.
