Older adults exhibit a reduced ability to ignore task-irrelevant stimuli; however, it remains to be determined where along the information processing stream the most salient age-associated changes occur. In the current study, ERPs provided an opportunity to determine whether age-related differences in processing task-irrelevant stimuli were uniform across information processing stages or disproportionately affected either early or late selection. ERPs were measured in young and old adults during a color-selective attention task in which participants responded to target letters in a specified color (attend condition) while ignoring letters in a different color (ignore condition). Old participants were matched to two groups of young participants on the basis of neuropsychological test performance: one using age-appropriate norms and the other using test scores not adjusted for age. There were no age-associated differences in the magnitude of early selection (attend–ignore), as indexed by the size of the anterior selection positivity and posterior selection negativity. During late selection, as indexed by P3b amplitude, both groups of young participants generated neural responses to target letters under the attend versus ignore conditions that were highly differentiated. In striking contrast, old participants generated a P3b to target letters with no reliable differences between conditions. Individuals who were slow to initiate early selection appeared to be less successful at executing late selection. Despite relative preservation of the operations of early selection, processing delays may lead older participants to allocate excessive resources to task-irrelevant stimuli during late selection.

ABSTRACT It is essential to use culturally appropriate, sensitive and specific tests that reflect true cognitive performance. However, several factors including age, education and gender can influence neuropsychological test performance. Objective: To examine the effects of age, education and gender on neuropsychological function in older adults using measures of global cognitive screening, attention, working memory, executive functions, memory, construction, language and parietal focal signs. Methods: This is a cross sectional normative study of 180 community-dwelling normal older adults. All participants were screened with the Hindi Mental Status Examination (HMSE), Everyday Activities Scale for India (EASI), Edinburgh handedness inventory (EDI) and MINI Screen, and followed by a detailed neuropsychological assessment. Results: Stepwise regression analysis revealed that education was associated with better performance on all the neuropsychological tests. Females performed significantly better on measures of memory. Further, most of the illiterate subjects, including low educated participants, refused to cooperate on measures of executive functioning. Conclusion: Education was found to be the strongest determinant of neuropsychological test performance followed by age and gender. Our study demonstrates that Indian healthy normal older adults with low education perform poorly on measures of planning and working memory. Traditional measures of planning and working memory should be avoided or used cautiously in the presence of low education. There is an urgent need to develop tasks for measuring executive functions, especially in low educated Indian older adults.
