Three questions are addressed in this study: (1) what is the effect of additional, unexplained content on achievement and perception? (2) is the effect altered by time? and, (3) what is the relation between student achievement and student perception? It was determined that the effect on achievement was not significant but the effect on perception…

The categorizations which humans make of the concrete world are not arbitrary but highly determined. In taxonomies of concrete objects, there is one level of abstraction at which the most basic category cuts are made. Basic categories are those which carry the most information, possess the highest category cue validity, and are, thus, the most…

This paper describes the results and implications of an investigation, based on dissonance theory, into attitude formation in introductory college science courses. The results of the study show that students who learned in ways they preferred registered a more positive attitude toward the course than did those who learned in ways they did not…

This paper presents background information, an introductory statement of theoretical positions, and brief abstracts of research papers from a symposium on the functional specialization of cerebral hemispheres in infants and children. According to one view of the development of cerebral specialization, the two hemispheres are initially…

The major objective of this study was to explore how preschool children's ability to delay gratification was affected when children were asked to attend to actual rewards rather than pictures of rewards. Sixty subjects, 3 to 5 years of age, were given a choice between two rewards and then placed in a delay of gratification situation. Half of the…

The purpose of this study was to investigate the relationship between field articulation and reading achievement at the end of grade one, and to investigate the effect on the pupil's reading achievement of the field articulation of the classroom teacher. The sample of pupils was drawn from eight first grade classrooms of female teachers. The…

Three experiments were conducted investigating information processing in a person perception task. A sequential judgement paradigm was employed in which subjects judged the suitability of stimulus persons for two different occupations. Traits describing each person were present for subjects' first judgements but not their second. Second decision…

Two experiments are reported examining the influence of the relationship between judgemental sets on the processing and integration of information in a person perception task. Experiment I showed that subjects made an occupational judgement about another more quickly when the judgement was similar rather than dissimilar to a previous occupational…

One hundred and sixty first grade boys and girls of normal intelligence were tested for ability to conserve multiple space relations. The criterion task apparatus was a wooden T with a model of schoolhouse attached and centered above the point of contact of the horizontal and vertical axis. The T had a track running the length of both its axes…

Research investigated whether cognitive learning scores and perceptual distortion measures of basic airmen would be influenced by instructor rank. Four groups of students, each composed of high, medium and low ability individuals, were created; each viewed a 20 minute television lesson on how to study. They differed only in that each was taught by…

This profile of significant research findings comprises a framework for analyzing and synthesizing information on the cognitive development of children. The variables used to systematize the literature search were: perception; motor development; language; conceptual activity; and learning, memory, and problem solving. The findings are arranged…

The review summarizes empirical findings and theoretical views related to the Stroop color-word phenomenon, in which naming of a color is disrupted and delayed by the presence of an "irrelevant" word denoting a color different from the color patch. It was deemed important to increase awareness of this phenomenon, since it involves basic…

The purpose of this research was to explore the development of, and relationships among, individual modes of (1) articulating knowledge about and evaluation of peers; (2) attributing causality for interpersonal events to the self and to others; (3) attributing one's own and other's behavior to intentionality or accident. Data was collected for…

The preliterate child must acquire from reading instruction at least the following skills: (a) appropriate scanning behavior, (b) letter and word recognition, (c) letter-sound generalizations, and (d) comprehension of written materials, at least to the degree that the reader can comprehend the same message when received aurally. Almost all modern…

The two studies outlined in this report gauged college undergraduates' ability to learn and to recall the content of certain passages when provided with "directed perspectives" or context clues. In the first study, 63 subjects were divided into three groups, were asked to read two stories, and were assigned a perspective (home buyer,…
