Reports a study of the lateral preferences and left minus right hand movement time of 129 pupils attending a dyslexia clinic for remedial teaching, and the incidences of left handedness and developmental language problems in relatives. (RH)

This analysis of manual asymmetry suggests that there are two main features to be explained: first, the normal bell-shaped distribution of relative skill, and secondly, the shift of the distributions toward the right. (Author)

Examines the effect of age and sex on hand preference and hand skill in two studies using six samples of children and a reanalysis of adult data. Results included findings that left- handers have an advantage over right-handers in visuo-motor speed. There was no evidence of increased dextrality with age. (JAC)

Studied hand skill and performance in children (N=115) of left-handed parents using peg moving tasks and soccer kicks. Concluded that being raised by two left-handed parents does little to hinder the expression of the rs plus gene. Correlations for handedness in families depend more on genetics than experience.
