Two experiments examined the hemispheric differences in free and serial recall of the auditory and visual sequences of verbal materials. In experiment 1, Japanese kanas were presented successively at different rates. Two different sequences were presented simultaneously to both ears or to both visual fields. Subjects were instructed to report as many items they could recall in order of their occurrence or in any order the subjects chose. Items presented to right eye or visual field were more liable to be reported in the order they delivered than those presented in left side. In experiment 2, whrere lists of the nonsense syllables were presented dichotically, subjects attended to one ear, and recalled items presented in attended side. Right-ear advantage appeared when long list was rapidly presented. In serial position curves, both primacy and recency effects were found when subjects attended to right ear, but recency effect disappeared when subjects attended to left ear. These results seemed to suggest a left hemisphere superiority in temporal coding of serial verbal stimuli. It was discussed that this difference may constitute distinctive features of different types of information processing in the left and right hemispheres.
