The development of writing posture in left-handed children and its relation to sex and reading skills.

Recordings of handwriting posture were taken on left-handed children at grades 1, 3 and 5. The main findings were that most young boys eventually change from a parallel to an inverted posture, while most girls show an early preference for the non-inverted writing posture. The data are discussed in terms of current notions about why the inverted posture develops. Discussion also centers on the finding that for grade 5 boys, the parallel posture is associated with poor reading scores.
