Sixty-four adults, (32 males and 32 females), were tested on two dichotic listening tasks, consonant-vowels (CVs) and musical melodies, during two sessions, one in the morning and one in the afternoon. The study was set up to examine two time-of-day hypotheses: Colquhoun's (1971) hypothesis that performance follows circadian body rhythms and would increase later in the day; and Folkard's (1979) hypothesis that a cognitive shift in processing occurs in the course of the day, such that performance on some tasks would improve while performance on other tasks would deteriorate. Neither Colquhoun's nor Folkard's hypothesis was wholly supported. The only significant effect was an improved right ear report for males in the afternoon on the Music task. It is suggested that further investigation into the transference of information between the hemispheres is warranted when considering the time-of-day effect.
