Effects of type of center fixation stimulus on visual-field preferences: a preliminary study

60 normal subjects (30 males and 30 females) viewed bilateral presentations of pairs of CVC or CVVC English words high in imagery. Three types of central fixation stimuli were studied: numbers, letters, and geometric forms. A significant main effect for kind of fixation was found, but not for sex, visual fields, or their interactions. Results are discussed relative to the processing of high imagery words by both the left and right hemispheres.
