Three experiments with 22 paid male undergraduates tested for the existence of laterality effects in iconic storage by employing a Sperling partial-report paradigm and lateralized presentations of alphabetical or pattern material. Even though an overall laterality effect was found in favor of the right visual field for the alphabetical material and in favor of the left visual field for the pattern material, the amount and time decay of partial-report advantage was similar in the 2 visual fields. Results indicate that hemispheric asymmetries occur beyond the iconic stage of visual information processing.

Abstract
Three experiments with 22 paid male undergraduates tested for the existence of laterality effects in iconic storage by employing a Sperling partial-report paradigm and lateralized presentations of alphabetical or pattern material. Even though an overall laterality effect was found in favor of the right visual field for the alphabetical material and in favor of the left visual field for the pattern material, the amount and time decay of partial-report advantage was similar in the 2 visual fields. Results indicate that hemispheric asymmetries occur beyond the iconic stage of visual information processing.
