DARKER and JORDAN, 2004. Perception of words and non-words in the upper and lower visual fields. Brain and Language, 89, p. 593-600
The findings of previous investigations into word perception in the upper and the lower visual field (VF) are variable and may
have incurred non-perceptual biases caused by the asymmetric distribution of information within a word, an advantage for saccadic
eye-movements to targets in the upper VF and the possibility that stimuli were not projected to the correct retinal locations. The
present study used the Reicher–Wheeler task and an eye-tracker to show that, using stringent methodology, a right over left VF
advantage is observed for word recognition, but that no differences were found between the upper and the lower VF for either word
or non-word recognition. The results are discussed in terms of the neuroanatomy and perceptual abilities of the upper and the lower
VF and implications for other studies of letter-string perception in the upper and the lower VF are presented.
