Stroop Effects when Naming Numbers instead of Colors

In the well-known color-naming version of the Stroop task, people’s reactions are slowed and less accurate when naming the color of a word that spells a conflicting color name (e.g. the word “RED” printed in green, correct response being “green”). The effect occurs because people have difficulty not reading the word, reflecting the idea that naming words is a lot more automatic than naming colors, and this causes lexical dominance in that words interfere more with naming colors than do colors interfere with naming words. The present experiment sought to determine if this lexical dominance effect extends to the case of number naming. Either a numeral (“7”) or the word version (“seven”) was presented for a vocal naming response. Above or below the target, either a numeral distractor (“3”) or a word distractor (“three”) appeared. The distractor was either congruent with the target (“7” paired with “7” or with “seven”) or incongruent (“7” paired with “3” or with “three”), and accordingly for word targets. The research question was whether word distractors would cause more interference than numeric distractors. Results showed that such was the case: Greatest interference occurred with numeric targets and lexical distractors, with less but still reliable interference with lexical targets and lexical distractors. Numeric distractors had no effect at all. The results indicate that lexical dominance extends beyond the limited domain of color naming in typical versions of the Stroop task.
