The effect of stimulus size and exposure duration on visual field asymmetries.

Two experiments are carried out in which stimulus size and exposure duration of verbal stimuli are shown to effect visual field advantages in a lexical decision task. More visually complex or briefer presentations are shown to be associated with LVF advantages supporting the hypothesis that the right hemisphere plays a role in visually analysing verbal stimuli. The stronger possibility, suggested by clinical data, that the right hemisphere can independently perform lexical decisions receives speculative rather than convincing support.
