abstract
A technique for restricting visual stimuli to a single visual field was validated in the present study. Vertical strips of opaque tape were applied to close-fitting goggles, obscuring one visual field on each lens. Forty-seven right-handed participants fitted with such goggles were found to be faster and more accurate in processing verbal stimuli presented to the right visual field than to the left. For a spatial task, accuracy was better and reaction times were shorter when stimuli were presented to the left visual field. Results indicate that the taped goggles were successful enough in restricting input to a single visual field to replicate typical laterality effects. 1985, The psychonomic Society, Inc..
