Sustained attention and related perceptuomotor functions

The present study examined the relationship between two measures of sustained attention on thr Continuous Performance Test (reaction time and omission errors) and several performance measures on neuropsychological tests. Analysis suggests thin sustained attention as measured by processing speed predicts performance on neuropsychological measures of relatively greater complexity and that the Stroop test, which requires maintaining steady focus on a changing stimulus field, may be more sensitive to lapses in attention than other neuropsychological rats.
