Pursuit Rotor Speed, Sex Differences, and Reminiscence in Young Children.

Data collected in a study of pursuit rotor abilities of 39 first grade pupils revealed that speed of response is a major dimension of performance in young children. Evidence for the early appearance of reminiscence was found, including data showing a significantly greater amount of reminiscence in males as compared with females. Moderate correlations between rotation speeds reflected the specificity of performance requirements at each speed.
