Three experiments examined the effect of temporal grouping on the timing of recall in verbal serial memory. Compared to an ungrouped condition, recall in a grouped condition produced a peak in latency between the groups (Experiment 1). However, the ratio of within- to between-group intervals at presentation was not reflected in recall (Experiment 2), contrary to the predictions of some oscillator models (Brown, Preece, Hulme, 2000; Burgess & Hitch, 1999). In Experiment 3, grouped and ungrouped lists of different lengths were compared to assess a recent version of the ACT-R model applied to serial recall (Anderson, Bothell, Lebiere, & Matessa, 1998). Recall latencies showed a cost at group onset related to group size and a cost for all items of the first group associated with carriage of a second group. Results are discussed with reference to oscillator models, the ACT-R model, and augmented versions of it. (C) 2002 Elsevier Science (USA). All rights reserved:
