The document describes an experiment that tested the effect of mental fatigue on performance. It hypothesized that mental fatigue would adversely affect performance. A subject completed 10 trials of a task, and their correct responses, errors, and time per trial were recorded. The results showed that the mean number of correct responses decreased from 16.2 in the first five trials to 8.8 in the last five trials, while the mean number of errors increased over the same period. This supported the hypothesis that mental fatigue lowers performance on cognitive tasks over time.
