Abstract

Age, education, and gender are the most common covariates used to define normative standards against which neuropsychological (NP) performance is interpreted, but influences of other demographic factors have begun to be appreciated. In developing nations, urban versus rural residence may differentially affect numerous factors that could influence cognitive test performances, including quality of both formal and informal educational experiences and employment opportunities. Such disparities may necessitate corrections for urban/rural (U/R) status in NP norms. Prior investigations of the U/R effect on NP performance typically have been confounded by differences in educational attainment. We addressed in this by comparing the NP performance of large, Chinese urban (Yunnan Province, n = 201) and rural (Anhui Province, n = 141) cohorts of healthy adults, while controlling for other demographic differences. Although the groups did not differ in global NP scores, a more complex pattern was observed within specific NP ability domains and tests. Urban participants showed better performance in select measures of processing speed and executive functions, verbal fluency, and verbal learning. Self-reported daily use of academic skills was predictive of many U/R differences. Controlling for academic skill use abrogated most U/R differences but revealed rural advantages in select measures of visual reasoning and motor dexterity. (JINS, 2011, 17, 000–000)
