Following a review of recent research in the University of Washington Department of Psychology project, Individual Differences in Cognition, analyses are reported linking performance in laboratory studies of cognition to performance on selected psychometric instruments. Intent of the study was to provide an empirical followup of Carrolls's (1974)…

The purpose of these studies was to provide evidence to support either the dual-coding hypothesis or the single-system hypothesis of human memory. In one experiment, college subjects were shown a mixed series of words and pictures either while simultaneously engaged in shadowing (repeating aloud) a prose passage presented via earphones or while…

This study tested the following hypotheses: (1) that children would use both verbal-associative and acoustic memory attributes when encoding words in memory, and that the recall of younger children would indicate dominance of the acoustic attribute while the recall of older children would indicate dominance of the verbal-associative attribute; (2)…

The focus of this study was on the effects which knowledge of semantic components may have on recall. It was hypothesized that after an introduction to discourse structures immediate recall would improve and recall which was delayed for one week would improve. Thirty-four unpaid volunteers between the ages of 16 and 26 were recruited and randomly…

Two conflicting hypotheses were investigated in this study. The first is based on an interference theory of forgetting and assumes that forgetting is largely a function of proactive interference, i.e., a result of interference by previously learned material. The second is based on the improvement of memory due to basic mechanisms that may operate…

Three strategies frequently employed in individualized instruction were tested in a three-way repeated measures design that involved eight computer exercises over a period of 6 weeks. Exercises compared individual with paired study, pretests with no pretests, and serial with parallel mastery. Posttests revealed an advantage for individual study…

The multivariate effect of task sequence, memory support, and state anxiety was investigated using a nonverbal concept acquisition task. Ninety-five Indian college students were randomly assigned to four treatment conditions resulting from the task sequences of 1) easy-to-hard and 2) hard-to-easy and from memory support versus nonmemory support.…

The purpose of this pamphlet is to increase teachers' comprehension of anxiety and its relation to children's thinking and forgetting, to their problem solving ability and their sense of competence. The pamphlet describes four parts of the anxiety experience: 1) the anxiety cue, the particular thought, memory, or sensation which precipitates the…

Research has indicated that across the second to fifth grade range, there was evidence to suggest a difference between the oldest and youngest groups in the memory representations which directed recall of logically related sentences. The developmental trend was from what seemed to be an unstable and fragmentary memory rperesentation, which…

A total of 34 children, ages 2 and a half to 6, were presented with sentences for imitation that either violated or honored a prenominal adjective ordering rule, which requires that size adjectives must precede color adjectives. Two response measures were evaluated in terms of these sentence types: latency to begin a sentence imitation and recall…

Children's short-term memory was studied under two experimental conditions: one in which recall was expected to be facilitated because of the provision of a study period, and one in which a distracting task was imposed that was expected to interfere with recall. Forty subjects at each of two age levels, 7 and 11 years, were tested in a…

Prompts in concept classification normally occur on the stimulus, while in memorization tasks prompts customarily are given on the response. Opposite results have been obtained for these two tasks with excessive prompting. This study used English-Russian word pairs to compare stimulus prompts (underlining the English word) with response prompts in…

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…

When one learns complex material, the important thing appears to be the ability to understand the material. Once understanding occurs, learning and remembering follow automatically. The conventional psychological literature says little about the processes involved in the learning of complex material--material that takes weeks, months, and even…

Three short studies were conducted on long-term effects of visual perception training on perceptual memory, involving the visual illusion of apparent movement, in educable and trainable mentally retarded children (EMR and TMR) and in learning disabled children (LD). Variables were lengths of training session and retention interval. Tables…
