abstract="Previously reported data on mirror tracking were reexamined for time-of-day (TOD) effects on performance and for the interaction of these effects with sex and practice effects. Analyses showed a significant linear decline of mean score from 0900 through 1300 hours, a sharp postlunch recovery at 1400 hours, and another significant linear decline from 1400 through 1700 hours. These effects were orthogonal to sex and practice effects. <br><br>DISCUSSION emphasized the importance of control for time of day in experimental design and suggested several hypotheses about the decremental effects of time of day.<p /><p>Language: en</p>",
