Neuropsychological test performance among Caribbean-born and U.S.-born African American elderly: the role of age, education and reading level. 
Within-group variation is an important yet under-studied component of cross-cultural neuropsychology.  The current study explored this potential source of variation in a neurologically healthy African American elderly sample by comparing the neuropsychological test performance of nondemented groups of Caribbean-born and U.S.-born African American elders who live in New York City.  Caribbean-born elders resided in the U.S. for a mean of 41.5 years (SD=17.0).  Results indicate that in general, Caribbean-born elders in this cohort did not demonstrate a unique cognitive testing profile from U.S.-born African American elders.  However, the Caribbean-born group demonstrated a higher quality of education than their U.S.-born counterparts.  The influence of demographic factors (i.e., age and education) on neuropsychological test performance was markedly attenuated in Caribbean-born elders though reading level was the strongest predictor of test performance for all elders, regardless of birthplace.
