Three experiments examined the processes mediating rat serial pattern learning for rule-consistent versus rule-violating pattern elements ("violation elements"). In all three experiments, rats were trained to press retractable levers in a circular array in a specific sequence for brain-stimulation reward (BSR). Experiment 1 examined the role of…

An item that stands out (is isolated) from its context is better remembered than an item consistent with the context. This isolation effect cannot be accounted for by increased attention, because it occurs when the isolated item is presented as the first item, or by impoverished memory of nonisolated items, because the isolated item is better…

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…

The hypothesis that free recall curves reflecting effects of serial position, presentation time and delay of recall are attributable to subjects' pattern of rehearsal was explored. Experiments varied the patterns of rehearsal to examine the effects on recall. (CHK)

Short-term retention of temporal and spatial order information were compared using the distractor paradigm. Use of phonemic coding and coding of information about temporal-spatial patterns were interrupted to observe subject's reaction and ability to recall. (CHK)

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…

Demonstrated is a covariance principle that causes the observer to assume that if one aspect of a two-dimensional figure (its perimeter or its area) is conserved, the other aspect must also be conserved (pseudo-conservation). Mentally retarded individuals, assuming no such fixed relationship, correctly judged the changed state of the nonconserved…

Expresses the opinion that education has overemphasized the written word and needs to move back to the oral tradition. Warns that Americans are trained to use the left brain whereas much of engineering needs right brain processing. Gives perspectives to improve engineering education. (MVL)

This research attempts to diagnose the skills required for successful spatial performance in order to provide a theoretical foundation for military training in such tasks as map reading, surveying, and navigation. It is known that successful performance on spatial tasks depends on task requirements (e.g., requisite knowledge, alternative paths to…
