Abstract

Two experiments tested text comprehension skills in adults varying in age from 20 to 69 years. A coherence judgment task (n = 39), in which the pragmatic connection of two sentences had to be evaluated, did not yield any age effects. Both error rates and reaction times were largely independent of age. In a word recognition paradigm (n = 60), testing the strength of different text representation levels, there was a gradual, linear decrease in performance with age, accompanied by a similarly gradual increase in processing times. The results confirm that aging affects comprehension under high memory demands, but spares the conceptual, situation-based levels. Most importantly, it was shown that these changes become apparent during middle age already. Implications for education and neuropsychology are discussed.
