title: A right hemispatial field advantage on a verbal free-vision task.
abstract: Within a fixed time limit for each stimulus item, right handers searched, in a top-to-bottom scan and from right to left for half the subjects and from left to right for the other half, among randomly placed and oriented words for target words that rhymed with a designated sound. A right hemispatial field advantage emerged, as well as an advantage for targets above as compared to below the horizontal meridian. A lateral X vertical location interaction showed a right-side advantage only for targets below the horizontal meridian and an upper target advantage only for targets on the left. Even though the task was presented in free vision, results were highly similar to prior findings with lateralized tachistoscopic presentation of verbal stimuli.
