Attentional bias and visual field asymmetry.

In mixed list tachistoscopic presentation of abstract words and random shapes, the probability of word and shape stimuli was varied to generate attentional bias and selective activation of the left or right hemispheres. While a right visual field advantage in accuracy was observed for words, and an effect of stimulus probability was observed across both visual fields in reaction time, no interactions were found between attentional bias and visual field asymmetry. The results can therefore be explained without reference to the attentional model and did not provide evidence of hemispheric activation or priming.
