Who’s got the global advantage? Visual field differences in processing of global and local shape
Résumé
In 1979 Martin a reported a right visual field (VF) advantage for local level responses and a left VF advantage for global level responses in Navon’s classical paradigmb with compound letters (Figure 1). These findings have since been confirmed in split-brain patients, in patients with unilateral brain damage, and in functional imaging with normal subjects. Despite this apparent convergence, VF differences in normal subjects seem flimsy and are reported in some studies but not others. This inconsistency may reflect small effects combined with small samples.
