Performance tends to improve during the day and deteriorate during the night (Colquhoun 1971;Lavie 1980;Carrier and Monk 2000).…”

The objective of this study was to analyze possible circadian variations in two components of executive functions: inhibition and flexibility. Participants were eight undergraduate students, age: 17.75 + 0.46 years, one male and seven female. They were kept in a constant routine protocol for 29 h. Rectal temperature was recorded every minute and responses to a computerized Stroop-like task with shifting criteria were recorded every 100 min. The task had three sections: match, no-match (index of inhibition), and shifting criteria (index of flexibility). There were circadian variations in rectal temperature, inhibition and flexibility. These cognitive processes showed a 1-2 h phase delay with respect to rectal temperature, and were modulated by sustained attention (time on task). The decline of these components of executive functions at night and in the early morning impairs decision-making and problemsolving, thus promoting errors while driving a car or working at night.

“…The interaction of noise and time of day is opposite in direction in different individuals (Loeb et al, 1982), and this is inconsistent with a single dimension of arousal/sedation (Broadbent, 1983). On the whole therefore the division into two groups by measuring paced/unpaced performance agrees well enough with that stemming from mutual potentiation or cancellation of effects.…”

Performance and its measurement.

Performance involves numerous sub‐functions, and cannot be treated as a unit. Several attempts have been made to separate functions impaired by different classes of drug: for example, high (monitoring) vs lower (performing) levels of function, early (perceptual) vs later (motor) functions, and strategic vs executive functions. The practical implications are that one cannot predict effects of a drug from a single performance test. One must either simulate the practical situation exactly, or use a battery of analytical tests to form a profile of effects. The latter is the policy urged in this paper.
