| Annotation | Two experiments are reported, examining the temporal structure of recall for categorisable word lists by younger and older adults. All participants showed `response bursting', in which recall order is clustered by semantic category, with longer inter-response times (IRTs) appearing between categories than within categories. Experiment 1 demonstrated that older adults, even when matched to younger adults in overall accuracy, differed in the rate of increase of between category IRTs with output position, but not in within-category IRTs. Experiment 2 showed that this interaction is eliminated when the names of the response categories are provided to the participants. Results are interpreted in terms of combined effects of an age-compromised episodic memory system (between-category IRTs) accompanied by a comparatively preserved semantic system (within-category IRTs) in healthy ageing.
