Lateral asymmetries in visual perception with and without eye movements.
A signal detection analysis was made of single letter recognition in the right and left visual fields. When letters were presented 2 degrees 3' to the right or left of a central fixation there were no significant differences between the fields in perceptual accuracy independent of bias when the subject maintained a central fixation point. However, when subjects were free to move their eyes a right field advantage was found. The results were discussed in terms of attentional bias theories and hemispheric specialization theories.
