Circadian and homeostatic variation in sustained attention.
2010
Human performance is modulated by circadian rhythms and homeostatic changes. Changes in efficiency in the performance of many tasks might be produced by variation in a basic cognitive process, such as sustained attention. This cognitive process is the capacity to respond efficiently to the environment during prolonged periods (from minutes to hours). There are three indices of sustained attention: general stability of efficiency, time on task stability, and short-term stability. The objective of this work was to analyze circadian and homeostatic influences on the indices of sustained attention. Participants were nine undergraduate female student volunteers (mean age 17.67 yrs, SD = 1.00, range 16–19 yrs) who attended school from 07:00–13:30 h, Monday to Friday. They were assessed while adhering to a modified 28 h constant-routine protocol during which feeding, room temperature, motor activity, and room illumination were controlled. Rectal temperature was recorded each minute, and indices of sustained atte...
