Instructional time to high proficiency or response time to high proficiency performance can be viewed as linearly related to the effective complexity of the task/display combination which is the essence of instruction or of performance. This proposition is concretely illustrated for bar graph-using performance of 4th and 6th graders who under most…

In a study of individual differences in long-term memory access, university undergraduates verified (1) whether an item was a member of a category; (2) whether two items belonged in the same category; and (3) whether two words had the same name. Reaction times from these tasks were correlated with verbal ability, as measured by performance on a…

A major contribution of information-processing theory to the psychology of remembering is the concept of memory or information retrieval. Several theories of the fact retrieval processes of the human memory, which constitute a substrate for any cognitive ability requiring stored information, have drawn heavily on certain data processing…

Three experiments are reported regarding reaction time. Letter comparison time was found to increase when other irrelevant letters were present, regardless of whether or not the letters made up a word or a word-like configuration. Word comparison time was found to increase when distractors were similar to targets. (Author/RM)

The author attempts to obtain some new evidence on simple addition processes in adults in order to evaluate the two additon models offered by Groen and Parkman (1972); a simple counting model and a more complex retrieval model, involving direct access and counting. (Author/RK)

Evaluates possible differences in the cognitive representations of semantic categories between children and adults independent of spontaneous memory skills. Response latencies on a classification task were compared for second, fourth, and sixth grades and college students. (Author/MP)

A model is proposed in which information processing is accompanied by dynamic processes, including the reorganization of items into active patterns and their subsequent displacement. Research using category names and instances showed that reaction times decreased with each successive repetition under one condition, but longer latencies were…

Primary purpose of this study was to investigate the processes underlying simple mental multiplication. (Author)

In four experiments, college students were presented with lists of either Armenian or English letters on a tachistoscope. The data indicate that extensive practice may be a necessary condition for capacity-free processing but may not be a necessary condition for involuntary processing. (Author/RD)

That additional exposure to memorial material improves subsequent retrieval probabilities was explored. The effect of a recognition test on subsequent recall and recognition of categorized lists was studied. Prior recognition tests increased recall of original items, but also increased intrusions. Similarly, prior exposure increased hit rates and…

Reaction time and accuracy do not always reflect the same perceptual processes; therefore, the convergence of reaction time with accuracy within the context of a specific information processing model should be demonstrated empirically rather than assumed a priori. (Author/PN)

The results demonstrate a use of semantic information to circumvent an item-by-item search of memory. Similar results have been obtained in the fact-retrieval paradigm of long-term memory. (PN)

Two strings of letters were presented. Subjects were instructed to indicate whether the second string contained the same elements as the first, regardless of position. Reaction time increased with the number of positions that the letters were displaced. Results indicate that order may be an important factor in retrieval from memory. (Author/BW)
