The effects of continuous and time-varied 85 dBA broadband noise on the performance of a Stroop-type color-word test and a related word-reading task were investigated. 10 subjects served in one of three groups receiving either continuous, periodic, or aperiodic noise. All subjects performed in both low noise (65 dBA) and high noise (85 dBA) conditions on 80 trials of both word reading and color naming. Median reaction times in the word-reading task were unaffected by either noise intensity or the time-varied aspects of the noise. However, median reaction times in the color-naming task were significantly elevated in the 85-dBA noise condition. Also, reaction times in the high aperiodic noise condition were significantly elevated relative to the continuous and periodic noise conditions. Results are discussed within the framework of arousal, filter, and information theories.

In this cross-sectional study, differences in interference control, one component of executive function, were investigated among three age groups, 15 early childhood (7- to 8-yr.-olds), 25 middle childhood (9- to 12-yr.-olds), and 20 young adults (21- to 30-yr.-olds). Participants were administered a computer version of the Stroop color–word test with an oral response; correct responses, response time (RT), and the interference ratio were examined. The data indicated that (1) most of the participants showed no errors in word reading, color-naming, and incongruent color-naming tasks; (2) in word-reading and color-naming tasks, RT for 7- to 8-yr.-olds was longer than that for 9- to 12-yr.-olds, while RT of 9- to 12-yr.-olds and young adults were comparable; (3) in an incongruent color-naming task, RT for 7- to 8-yr.-olds was longer than RT for 9- to 12-yr.-olds, which was longer than RT for young adults; and (4) the interference ratio was higher in 7- to 8-yr.-olds than in 9- to 12-yr.-olds, which was higher than in young adults. These results suggested the difference in interference control between early and middle childhood reported on the go/no-go task and the stop-signal procedure would be observed in the Stroop color–word paradigm as well. The utility of this modified Stroop color–word test for those with intellectual and developmental disabilities was discussed.

Learning Test

Serial neuropsychological assessment is often conducted to monitor changes in the cognitive abilities of individuals over time. Because practice effects occur and the reliability of test scores is less than perfect, it is difficult to judge whether varying test results should be attributed to chance trends or to real changes in underlying cognitive abilities. In a large sample of adults (age range, 49–81 years), we evaluated the influence of age, gender, and education on test–retest changes in performance after 3 years on Rey's Verbal Learning Test (VLT), the Stroop Color-Word Test (SCWT), and the Letter Digit Substitution Test (LDST). A new statistical method was applied to assess the significance of changes in test performance (i.e., the regression-based change method). The results showed that test–retest changes differed as a function of age for the VLT Total recall 1–3, VLT Total recall 1–5, VLT Delayed recall, and LDST measures. An age × gender interaction was found for the SCWT Interference change score, suggesting that the age-related decline in executive functioning after 3 years was more pronounced for males than for females. A normative change table with appropriate corrections for the relevant independent variables was established. (JINS, 2008,14, 71–80.)

We present normative data from a Hebrew language version of the Stroop color-word test. In this sample of college-educated Israeli young adults, 18 women and 28 men with a mean age of 28.4 yr. completed a Hebrew language Stroop test. When compared with 1978 English language norms of Golden, Hebrew speakers were slower on color-word reading and color naming, similar on naming the color of incongruently colored names of colors, and showed less interference. Slowed color-word reading and color-naming may reflect the two-syllable length of the Hebrew names for one-syllable length English language colors; reduced interference may reflect the exclusion of vowels in much Hebrew printing and subjects' ability to provide competing, nonconflicting words while naming the color of words in which the hue and the lexical content do not match.

AbstractAsurge in the search for endophenotypes for psychiatric disorders has occurred in the past several years. An important criterion of an endophenotype is that it is heritable. Two of the most widely used executive cognitive functioning measures are the Wisconsin Card Sorting Test (WCST) and the Stroop Color-Word Test. Each has been considered as a possible endophenotype. However, research on the heritability of each of these measures is sparse, and in the case of the WCST, mixed. As part of a pilot twin study examining cognitive functioning and personality in adults, the WCST and the Stroop were administered to 80 monozygotic and 29 dizygotic twin pairs screened for absence of neurological disease and head injury. Results replicated and extended previous findings for moderate heritability of Stroop performance. However, the WCST showed little evidence of genetic influence, suggesting that it might not meet one of the criteria for an endophenotype.

Color Priming

The effect of prior word and/or color activation on subsequent color naming was examined in a discrete-trials Stroop task. Both word and color primes increased color-word interference, and the magnitude of the priming effect increased as the number of priming dimensions increased. The maximal interference usually produced by incongruent Stroop stimuli was reduced when such stimuli were preceded by primes which activated both word and color dimensions. The results were discussed in terms of models which attribute color-word interference to the relative speed of word reading and color naming.

Interference Test

16 subjects performed a conventional chart-form and a card-sorting form of the Stroop color-word interference test. Interference scores on the two forms were positively and significantly correlated, while neither word reading nor color naming scores showed a significant correlation. It is suggested that the ‘Stroop effect’ has some, but limited, generality and that forms not requiring verbal response may be more useful than the traditional chart version in providing a general measure of interference proneness.
