Have there been any studies that found that an extremely high (or low) Stroop test score correlates with certain personal characteristics, abilities or aptitudes, or would all such conclusions be outside the test's scope?


N.B.: There are many varieties of "Stroop-like" tasks, which as a class are often called implicit association tests or IATs. Since those are likely to test attributes related to their specific construction, I have excluded them from this answer.

There have been a variety of papers studying correlations of Stroop performance with other characteristics.

Ward et al. (2001) examined the correlation between Stroop effects and executive control, finding that Stroop costs and other measures of executive control were not well correlated.

Brewer et al. (2008) found sizable correlations between neural activation in Stroop testing and treatment outcomes among cocaine-dependent patients; they interpret this to suggest executive control differences are determinative in treatment outcome, but this interpretation is contradicted by Ward et al. above.

Less recently, Golden (1975) found the Stroop test to correlate with measures of creativity; I have found no more recent discussion of this so cannot speak to its currency.

The Stroop test also correlates with age and education level (Van der Elst et al. 2006).

When emotionally charged words are presented (Emo-Stroop), the Stroop task was found to correalte with high state anxiety.(Dresler et al 2009)

You can find a review in "Secondary Influences on Neuropsychological Test Performance", edited by Peter Arnett. (Its on google books)
