The effect of familial sinistrality on perceptual learning.

Perceptual learning as measured by adaptation to prismatically displaced vision was contrasted in groups of familial sinistral (FS) and familial dextral (FD), strongly right-handed adult females. The FS group exhibited significantly larger target pointing and eye positioning adjustments than the FD group. Further, only the FS group showed transfer of training from the hand used during prism viewing to the unobserved one.
