Sets of pairs for a multiple-item recognition (verbal discrimination) learning task varied in their number of presentations during a single extended study trial. The test phase required old-new and right-wrong (functional) identifications of individual items. Results suggest that recognition of prior wrong items are mediated by frequency cues…

Past research has distinguished between two alternative representational systems that are used in perceptual learning--distinctive features and schemas. This study examines the influence of short-term memory on the initial utility of these systems and the influence of long-term memory on retention of these forms of learning. (Editor)

Attempts to develop an index that will provide a broader data base from which to determine the relative strengths of list items in memory. (Author/RK)

To show how a subject's memory of previous responses and their outcomes affects responding, as in Buchwald's cognitive model, the subject in the present study had to recall his previous response and its outcome before choosing the correct response. (Editor/RK)

Four free-recall experiments are reported that investigate the relationship between the organization of rehearsal and the organization of recall. (Editor)

The idea was explored that different subjects may use qualitatively different encoding strategies with the same information presented within the same experimental situation. The premise was also studied that different strategies may be evoked by subtle differences in advance instructions or in the context of the task. (Author/MH)

Three reaction time (RT) experiments using a modified Strenberg procedure were conducted to determine the number of memory representations maintained for perceptual (dot-pattern) concepts. (Editor)

The present research represents an initial attempt to compare the results obtained using artificial information with results obtained in a typical semantic memory experiment. (Editor)

In the present study an attempt was made to investigate the duality of encoding mechanisms via instructional sets that were independent of stimulus characteristics. (Author)

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…

A review of some recent experiments suggested that general similarity between words might successfully function as a structural principle for semantic memory. A spatial model based on that assumption is proposed. The relation of this model to network and set-theoretic models of semantic memory is discussed, as is the relation of this model for…

The nature of the target designation process--which involves forming interassociated mental structures to allow retrieval of individual items of information--was studied. It was shown that visual imagery instructions improved target identification as well as word recognition but did not appear to affect the representational format. (Author/MH)

The ability of preverbal infants to abstract a prototypical representation of a category, when presented with examples of an artifically constructed category, was investigated. It was determined that infants could process visual information constructively and could take a more active role in category formation than previously believed. (Author/MH)

Sought to elucidate the nature of odor memory by applying paradigms from verbal learning and semantic memory and to investigate two processes affecting paired-associate performance. (Author/RK)
