Hemispheric asymmetry in making absolute judgments of monaurally presented pure tones.
Some recent studies have suggested that hemispheric asymmetry may be related to the quantity of information contained in a stimulus. To test this possibility, 20 subjects were given an auditory absolute-judgment task in which they were required to identify 3, 5, or 7 pure tones recorded on a tape. The presentation was monaural, and headphone placement was randomly alternated across subjects. The left ear showed a statistically significant advantage tones. The result is discussed in terms of previous work on auditory channel-capacity and the desirability of using an absolute-judgment paradigm to study hemispheric asymmetry for other kinds of stimuli is indicated.
