Education, age, and the Brown-Peterson technique

, : Education, age, and the Brown-Peterson technique. Developmental Neuropsychology 19(3): 237-251

In this article, we discuss the effects of education level and age on short-term memory. The performance of young and elderly persons was compared on an adapted version of the Brown-Peterson procedure. Participants were asked to report consonant trigrams, after variable time periods, during which they performed a mental addition task or an articulation task. A control condition consisted of a no-interference task. Both age groups were divided according to individual educational level (greater or less than the median number of school years in each age group). The results revealed a significant effect of education. Moreover, the education effect interacted with the task: participants with less education were more impaired in mental addition than in articulation. However, neither the age effect nor the interactions involving age reached significance. These results indicate that education, to a greater extent than age, should be considered a determining factor of performance when interpolated tasks of high demand are used with the Brown-Peterson procedure.
