title: Right- and left-hand skill: failure of the right shift model.
abstract: Annett's right shift model of the distribution of skill asymmetry, and of the genetics of handedness, is examined in relation to several sets of data. It is found to be a less adequate description than is the more intuitively obvious 'symmetric bimodal' model, which is described in this paper.
