title: External auditory canal temperature and reaction time relationship during long performances.
abstract: In order to study the relationship between body temperature and reaction time (RT), and check the hypothesis proposed by Kleitman (Sleep and Wakefulness, University Press, Chicago, 1963) about a 'Basic Rest-Activity Cycle' (BRAC), RT tasks were delivered to 24 subjects at 10-min intervals for 320 min, while simultaneously registering bilateral ear canal temperatures. Time series analyses in frequency and time domains were applied to the data. Our results did not show a 90-100 min ultradian rhythmicity in the performance of RT tasks, but 6 of the 24 subjects presented significant periods within limits of BRAC in temperature.
