Research on adult sibling relationships suggests a concern about the quality of these relationships. The meaning of closeness in sibling relationships across the adult life span, its perceived origins, maintenance, and dynamics, were investigated in a sample of 55 adults ranging in age from 25 to 93 years. Semi-structured interviews with the…

This report summarizes the research results and provides a reference. The basic question addressed was, "Is performance on multi-component tasks predicted by performance on the individual components performed separately?" In the first series of experiments, a dual task involving memory and verbal processing components to predict a…

A reader's ability to recognize an author's top-level structure in a passage is a useful strategy for organizing textual information for memory purposes. Even without specialized training, many adults and some fifth grade children have this ability. Other children in fifth and ninth grades, and in classes for the mildly mentally handicapped, have…

This study was designed to examine relationships between three variables of analysis/integration skill in visual perception and the tendency to retain differentiated memories of sequential visual images in a sample of 206 university undergraduates. Correlation techniques and factor analysis were used to analyze relationships between the perceptual…

Memory performance differences of mental age matched (9-12 years) educable mentally retarded (EMR) (n=56) and normal (n=56) children were examined in two experiments using the F. Craik and R. Lockhart levels of processing framework. In experiment 1, Ss were randomly assigned to an incidental, intentional, or planned intentional learning condition,…

The effects of sentence imitation and picture verification on the recall of subsequent digits were studied. Stimuli consisted of 20 sentences, each sentence followed by a string of five digit names, and five structural types of sentences were presented. Subjects were instructed to listen to the sentence and digit string and then either immediately…

An experiment to determine the effects of perceptual organization on learning and remembering a motor task is described. Four test groups received different methods of presentation of movements to be learned--sequential-sequential, sequential-random, random-sequential, and random-random. Analysis of variance was used to examine results. Results…

Three experiments were conducted to determine the effects of student-preferred incentives across instructional tasks that varied in length and relatedness to course content. The first study was done to determine the effects of the opportunity to earn points toward the course grade. There were no differences between incentive and no-incentive…

This study was designed to investigate whether problem solving inefficiency in preschool children is the result of subprocess deficiencies in the children's use of logical rules and to assess the influence of 2 mnemonic components (encoding and rehearsal) on problem solving ability. The study subjects, 108 preschool children, were presented with…

In this study, cognitive processes hypothesized to be relevant to the digit symbol task of the Wechsler Adult Intelligence Scale (WAIS) were examined. Fifty-two undergraduate education students were divided into four groups to receive four different treatments. All the students took the digit symbol test, followed immediately by a test of their…

Two kinds of memory organization are distinguished: segregrated versus integrated. In segregated memory organizations, related learned propositions have separate memory representations. In integrated memory organizations, memory representations of related propositions share common subrepresentations. Segregated memory organizations facilitate…

Children from kindergarten through grade 2 were asked to copy, then print from memory, each of the 41 reversible letters and numbers administered individually on slides presented in random order. The main findings of an experiment with 179 children drawn from two elementary schools show that mirror-image reversals and other errors (1) take place…
