The effect of XXXX on next day effort.

The study had two primary objectives. The first was to determine whether @entity25 results in a preference for tasks demanding minimal effort. The second was to evaluate the quality of performance when @entity1 , under conditions of @entity25 , have control over task demands. In experiment 1, using a repeated-measures design, 50 undergraduate college students were evaluated, following one night of no @entity25 and one night of @entity25 . The Math Effort Task (MET) presented addition problems via computer. @entity1 were able to select additions at one of five levels of difficulty. Less-demanding problems were selected and more additions were solved correctly when the @entity1 were subject to @entity25 . In experiment 2, 58 undergraduate college students were randomly assigned to a no @entity1949 or a @entity1949 condition. Sleep-deprived @entity1 selected less-demanding problems on the MET. Percentage correct on the MET was equivalent for both the non-sleep-deprived and sleep-deprived groups. On a task selection question, the sleep-deprived @entity1 also selected significantly less-demanding non-academic tasks. Increased @entity25 , @entity1295 , and reaction time were associated with the selection of less difficult tasks. Both groups of @entity1 reported equivalent effort expenditures; sleep-deprived @entity1 did not perceive a reduction in effort. These studies demonstrate that @entity25 results in the choice of low-effort behavior that helps maintain accurate responding.
