Lateralization of Visual Spatial Attention in Righthanders, Left-handers and Converted Left-handers: A Comparative Investigation with Line-bisection Task
The effects of handedness, in particular, of successfully switched left hand writing, and sex on line bisection performance were examined in 254 normal adults (99 male), divided into three handedness groups: right-handers, ordinary left-handers, and "converted" left-handers, self-determined as left-handers. Study findings suggest that handedness and sex has a small effect on bisection errors (both, the direction and the magnitude of bisection deviations), but the switching handedness is a significant factor modulating the direction of bisection deviations.
