The interrelations between mental age (MA), IQ, and mediation were studied in 72 retardates in special classes. Subjects were selected to fall into sexually balanced groups of six in 12 MA-IQ categories (IQ 50-59, 60-69, 70-79, and 80-89; MA 4-0 to 5-11, 6-0 to 7-11, and 8-0 to 9-11). The apparatus alternately displayed two pairs of stimuli, and…

Research is presented that is derived from the hypothesis that a person's interpretation of emotional stimulus is affected by the painted hue and the light intensity of the visual environment.

Repeated exposure to tests composed of memory items was compared to repeated exposure to tests including higher-level cognitive items and to tests composed of both item types. Other design factors were sex, ability level, subject matter sequence (science and social studies), and learning session. (A sample of 2008 eleventh-grade students…

An investigation of the short term stability of infants' responses to strangers was conducted. Ss were 60 randomly chosen full-term family-reared infants, 30 boys and 30 girls, selected to fit into three age groups of 8, 10 and 12 months. The experimental design was such that the order of first, second, and third visits was counter-balanced…

Two studies examined serial recall process of first-grade Canadian children from inner-city and suburban backgrounds. In the first study significant differences were found in the serial position curve of recall. Suburban children recalled a greater number of early-presented, primacy items, while inner-city children who had equivalent span…

To test the mere exposure hypothesis, subjects were exposed to 20 slides of black and white stimulus persons. Based upon pre-experimental ratings, each slide had been initially assigned to one of four groups: high favorable black, high favorable white, low favorable black, and low favorable white. The experimental group, consisting of 25 white…

The negative results to an assessment of a Bank Street-sponsored Follow Through program raised questions about conventional ways of assessing the effects of educational programs. Children in a Follow Through program using the developmental-interaction approach and children in conventional classrooms were observed and tested for comparison. The…

An attempt was made to develop and validate a Piagetian-based written test with successful use of the logic of specific Piagetian tasks defined as the criterion. Ninety-six randomly selected nine to sixteen year olds, stratified by age, were individually presented the Piagetian tasks of pendulum, balance, and combinations, and group administered a…

An earlier study (ED 048 772) sought to determine the perceptions of televised violence among pre-teen males from varying racial and socio-economic backgrounds. In this replication of the study teenage boys were used as subjects. The general method of the study was to show the boys a sequence of television vignettes, comprised of violent and…

The relationship between paradigmatic and syntagmatic oral associates and reading readiness test scores was investigated. Paradigmatic associates were defined as responses demonstrating superordinate, coordinate, contrast, or part-whole relationships, and syntagmatic associates were defined as any other responses. Subjects were 52 first graders…

The Washington Principal Evaluation Inventory provides a measure of principal effectiveness. Not only does the inventory yield a total measure of overall principal effectiveness, but also meaningful scores for each of seven dimensions of administrator behavior. The inventory consists of 64 statements of principal behavior on which teachers and…

A study is reported which is based on the assumption that a teacher's presentation may vary as a function of student set. A guest lecturer was presented to each of 2 introductory psychology classes, one of which had been told that the lecturer was a "cold" person, and the other that he was a "warm" person. The lectures were taped and rated to…

This study investigated several questions generated by cueing system research. The cueing system is perceived as a means of directing our categorizing behaviors in the processing and recall of information. Experiments involved a comparison of categorical cueing systems on a given task in relation to two control areas: (1) subjects using a free…

This study provided an assessment of the effectiveness of simulation in developing attitudes, values and cognitive understanding in a teacher education program. The experimental participants were 24 undergraduates enrolled in a course on learning and development. The course consisted of demonstrations of problems faced by the teacher in the inner…
