Stroop interference, practice, and aging

We report two experiments that investigate practice effects on Stroup color-word interference in older and younger adults. Both experiments, employed a computerized, single-item version of the Stroop task with a voice response, and both involved practice over hundreds of trials. Both experiments showed generally similar practice patterns, including a practice-related reduction in the size of the color-word interference effect. However, the older group continued to show a larger interference effect throughout practice. These findings indicate that older adults;how the same trend in practice-related improvement on the Stroop task as younger adults.
