title: Preliminary findings with a new Vietnamese Stroop test.
abstract: Stroop performance was compared in primary Vietnamese- vs English-speaking individuals (age range 19-68 years), currently living in the USA. A modified Vietnamese Stroop task mimicked word, color, and interference effects of an English-language Stroop test. Stroop performance (items correctly completed and interference "cost") did not differ significantly between 30 Vietnamese Americans whose first language was Vietnamese (M age 34.3 yr.) vs 30 American-born individuals whose first language was English (M age 31.2 yr.). Expected performance decrements with aging were observed in English-language Stroop performance but not in Vietnamese-language Stroop performance, which instead exhibited a trend towards the opposite pattern. Unexpected group differences associated with age in Stroop performance may reflect subtle differences in task demands, not evident in simple category performance scores, or alternatively, cultural or neuropsychological differences in the study groups.
