摘要: In order to study the existence of ultradian rhythms in human performance, reaction times and omissions responses signal stimuli were registered from 17 subjects performing a selective auditory attention task, at 15-minute intervals 9:00 am 3:00 pm. The task consisted selectively focusing attention, first left then right ear, pressing button every time stimulus was detected. Rhythmometric analysis showed significant (p < .05) both temporal course number stimuli. Results are discussed terms level difficulty processing resources involved.
