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

Two studies (1) compared the ability of pre- and post-operational children to seriate sets of 4 temporal sequences presented simultaneously and (2) examined the ability to recall sequences when given the initial, middle, or terminal item as a retrieval cue. (SB)

An extension to Murdock's Theory of Distributed Associative Memory, based on associative chaining between items, is presented. The extended theory is applied to several serial order phenomena, including serial list learning, delayed recall effects, partial report effects, and buildup and release from proactive interference.

The role of reversibility in children's comprehension and memory for sequences of pictures was investigated for children in preschool, kindergarten, and first and second grades. Bidirectionality in the ability to remember and infer antecedents and consequences was assessed. (JMB)

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)

The performance of the older subjects (10 years and up) was facilitated by the organizational cues, whereas that of younger subjects was not. (Author)

Using story retelling as an index of language ability, it is difficult to disambiguate comprehension and memory deficits. Collecting data on the serial position effect (SPE), however, illuminates the memory component. This study examined the SPE of the percentage of information units (%IU) produced in the connected speech samples of adults with…

Deals with memory for lists of items. The literature is briefly reviewed, and the main difficulties for traditional explanations of serial order effects are noted. (RK)

Deficits in position memory particularly seemed to be the major distinguishing variable between normals and retardates in the present study. (Authors)

Using recognition rather than recall test procedures gives results which are inconsistent with the main features of the visual trace model for short-term memory. (Author)
