Monocular recognition of letters and Landolt Cs in left and right visual hemifields.

Hemispheric Asymmetries in Tachistoscopic Information‐processing

“…of central vision are bilaterally represented at the cortex and that stimuli displaced by less than approximately 2.5 deg. from fixation are transmitted to both visual receiving areas (Adler, 1965;Ruch et al, 1965;Wolf, 1968 Markowitz & Weitzman, 1969). McKinney (1967) has, however, shown that lights perceptually fragment more rapidly when presented in the LVF.…”

Hemispheric symmetry in contrast and orientation sensitivity

“…Rose (1983) points out that, since only monocular viewing was used, these discrepancies could be due to individual differences in nasotemporal asymmetry (see Rijsdijk et al 1980). However, although other research has shown that sensitivity is somewhat better in the temporal hemiretinas (Mandelbaum & Sloan, 1947;Markowitz & Weitzman, 1969), this cannot alone account for visual field differences (see Fontenot & Benton, 1972). Nevertheless, retinal sensitivity could interact with hemispheric superiority such that hemispheric superiority and retinal sensitivity could cancel each other, thus abolishing visual-field differences, or differential retinal sensitivity in the absence of hemispheric superiority could create the impression of cerebral asymmetries (Kimura, 1969;Markowitz.…”

Role of Visual Acuity in Tachistoscopic Recognition of Three-Letter Words

“…Markowitz and Weitzman (1969), for example, found that laterality effects otherwise present for the left eye viewing of trigrams, were abolished by providing pre-knowledge of target presentation to their Ss. There is some basis for the speculation that this procedural arrangement, which afforded greater comparability, across our two tasks, could have worked against the emergence of word laterality effects.…”

“…On the other hand, Barrel1 and Parks (1969) in a binocular color-rivalry situation found a tendency for temporally imaged targets to predominate in perception. Markowitz and Weitzman (1969) and Overton and Wiener (1966) provide somewhat hybrid outcomes in that temporal retinal superiority in the recognition of lexical materials was found but only for the left eye.
