AnnotationTwo experiments tested one aspect of Hasher and Zacks' 1988 reduced inhibition hypothesis, that old age impairs the ability to suppress information in working memory that is no longer relevant. In Experiment 1, young and older people were asked to recall lists of letters in the correct order. Half of the lists contained repeated items, while half were control lists. Recall of non-adjacent repeated items was worse than for control items. This Raschburg effect was larger (i.e. greater response suppression) in older than younger people. In Experiment 2, young and older people were required either to recall the list, or to report if there was a repeated item. Repetition detection was high and similar in the two age groups. When age differences in overall performance were taken into account, there was evidence of increased repetition inhibition with age in both experiences. Thus, contrary to the general reduced inhibition hypothesis, the specific process of response suppression during serial recall is not reduced by ageing. (RH).
