Superior recall of letters in the right visual field with bilateral presentation and partial report

The present investigation addresses itself to the question of whether a right visual field effect would emerge under conditions of bilateral letter presentation and partial report. Tachistoscopic trials consisting of eight letters, four in each field, were presented for 100 msec., to twenty right-handed adults. Ss were instructed to report the content of only one field on each trial. Under these conditions a right field superiority was obtained and an interaction between field and stimulus position. The field asymmetry appears to reflect the operations of cerebral dominance while the interaction suggests the influence of mnemonic factors.
