Dichotic listening in the morning and evening.
Normal subjects needed greater intensity to detect dichotic and monotic click stimuli in the evening compared to the morning. Also, the asymmetry for detecting dichotic clicks shifted from morning to evening. The morning pattern of left ear lead advantage was absent in the evening. In contrast, there was no morning versus evening change in either overall accuracy or right ear advantage for consonant-vowel discrimination.
