Digit comparison is strongly related to individual differences in children's arithmetic ability. Why this is the case, however, remains unclear to date. Therefore, we investigated the relative contribution of three possible cognitive mechanisms in first and second graders' digit comparison performance: digit identification, digit--number word…

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…

The issue of whether information to which little or no attention is paid can have lasting effects is of interest to psychologists as well as educators and advertisers. Two experiments were designed to examine whether focused attention is required, whether the immediate memory task is important, or whether subjects' knowledge that repetitions are…

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 mediating role of learning in the relationship between repeated exposure and affect was explored and supported in three experiments involving a total of 229 undergraduate participants. It was found that both learning and affect measures behaved in essentially the same way as a function of exposure duration (experiments I and III), serial…

Endpoint and distance effects have been observed in the protocols of subjects learning linear orderings. These were produced by subjects learning the frequency of word occurrence as the greater member of a relationship. Error patterns were similar on all trials. (CHK)

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)

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…

Well-known questioning strategies, built on question classification systems, are examined. Types of question classification systems are identified as: "hierarchical," which are sequential and cumulative; "non-hierarchical," which are based on elements which should not be rank ordered; systems which are "context-bound" to specifics; and…
