The effect of unimanual performance on speed of verbalization

Male college students (N = 20) named colors under two levels of difficulty while turning a wheel with one hand. The hand used was found to be unrelated to naming time. In a second experiment, 24 male college students performed a dowel-balancing task while repeating a simple sentence and while remaining silent. Verbalization was found to be unrelated to hand used while dowel-balancing. The results failed to replicate and extend earlier findings.
