The grouping of list items is known to improve serial memory accuracy and constrain the nature of temporal errors. A recent study (M. T. Maybery, F. B. R. Parmentier, & D. M. Jones, 2002) showed that grouping results in a temporal organization of the participants' responses that mimics the list structure but not the timing of its presentation.…

The production of complex sequences like music or speech requires the rapid and temporally precise production of events (e.g., notes and chords), often at fast rates. Memory retrieval in these circumstances may rely on the simultaneous activation of both the current event and the surrounding context (Lashley, 1951). We describe an extension to a…

Two experiments examined memory load, rule frequency, and rule arrangement in the prediction learning of serial digit patterns. (Editor)

Using a network of comparisons, B. Hayes-Roth and F. Hayes-Roth found that subjects performed better on adjacent than on nonadjacent comparisons. Results suggested that such networks are processed in a manner fundamentally different from simple linear arrays. Here subjects were required to learn a similar knowledge structure. These results…

This research investigates whether subjects who receive the premises for a linear ordering in story format acquire a different memory structure and use a different solution algorithm than subjects who receive the same premises in equation format. (Author/RK)

The tasks with item and position probes seem similar. Given an item probe, a subject must recall its position in the spatial array; given a position probe, the item in that position in the array. Analysis of correct responses and latencies showed that item and position probes yielded different results. (Editor/RK)

Two experiments compared Ss' serial recall of 16 hierarchically formed patterns of ordered digits. (Author)

Little is known about the accuracy of temporal codes for memories, and still less about the nature of the codes. This report addresses the central question of the mechanisms by which order information is attached to memories. The results of 16 experiments indicate the role of some independent variables on temporal coding in relatively short-term…

Forty-eight grade-three children and 48 grade-eight children were presented respectively with six- and eight-letter sequences for written free recall. The older children, as had adult subjects in previous studies, showed a greater tendency to recall serially with a four-letters-per-second presentation rate than with a half- or…
