A longitudinal field study conducted in Turku, Finland, traced the development of aggression as a function of the viewing of violence by children from the ages of 7 and 9 to the ages of 15 and 17 to explore the connection between violence viewing and viewers' aggression, and to shed light on the question of causality. The 220 subjects, both male…

While much of microcomputer-based instruction (MCBI) is oriented to provide self-paced instruction to adjust for individual differences, there is some indication from cognitive theory that self-pacing may not be the best approach to improving learning. In addition, research in the area of cognitive imagery mediation has indicated that imagery…

Two studies were conducted to extend the application and explore the parameters of the concept tree and rational set generator instructional design techniques. The first study was conducted with high school English students. Results indicated that students who studied the concept tree performed no differently on the classification tests than…

Conducted to determine whether use of computerized file-management programs can enhance the development of information processing skills, this two-treatment experiment found that seventh through twelfth grade students in the computer-using/structured activities group received significantly higher mean scores than the…

This paper considers the style and structure of broadcast educational television programs in relation to learning outcomes, and proposes a study to identify those key factors which intervene or affect this relationship. The types of structure examined include simple or complex and self-standing or integrated programs, and types of style include…

A study involving 103 male and 117 female students entering a major urban university assessed the interaction between test anxiety and skill deficits. The effects of prior achievement and test anxiety on performance on two competency exams were also examined. Instruments consisted of minimum competency tests for reading comprehension and…

Interactive decision making (IDM) refers to teachers' selection and rejection of alternative courses of action during instruction. Previous research indicates that teachers report making interactive decisions when their plans are disrupted. A study generated hypotheses about teachers' IDM using the grounded theory approach--an inductive system for…

This paper describes NEOMYCIN, a computer program that models one physician's diagnostic reasoning within a limited area of medicine. NEOMYCIN's knowledge base and reasoning procedure constitute a model of how human knowledge is organized and how it is used in diagnosis. The hypothesis is tested that such a procedure can be used to simulate both…

The emphasis in this study is on the development of a diagnostic measurement model for instruction. The content used was junior high science, but the content and subjects were used primarily as a means to an end. The model represents an attempt to incorporate Gagne's learning taxonomy into Tyler's model of the educational act. Focus is on the…

To compare the adolescent's mode of thinking on one specific measure of cognition, conservation of volume, with his mode of thinking on a task simulating a familiar real-life situation, a study was made using 162 students (76 males and 86 females, 13.4 to 17.7 years of age, grades 7,8,9,10,12). The students, grouped according to age into four…

The traditional hypothesis that extreme attitudinal positions on controversial issues are likely to produce low understanding of messages on these issues--especially when the messages represent opposing views--is tested. Data for test of the hypothesis are from two field studies, each dealing with reader attitudes and decoding of one news article…

The present study outlines a specific three-level hierarchy of the cognitive system, in particular the relationship between cognitive and metacognitive processes in mathematics. The emphasis is on the impact of processing efficiency and working memory ability on the development of self-representation and mathematical performance. We developed and…

To examine the role of elaborations in learning a procedural skill (i.e., using a personal computer) from an instructional text, 88 members of the Carnegie-Mellon University community (students, faculty, and staff members) participated in two experiments. Experimental sessions consisted of a reading period followed by a task performance period in…

This monograph investigates aspects of language processing that are not specialized in the left hemisphere, and claims that there are "levels" (such as pitch functions) and "subsets" (such as phrase structuring) which are different in essential ways from each other, and from the aspects of speech and language which are typically lateralized.…

The hypothesis, that the importance of language to mankind lies not so much in the fact that it is the means by which we cooperate and communicate with each other as in the fact that it enables each of us, as individuals and in cooperation, to represent the world to ourselves as we encounter it, is presented. In infancy, the representation is made…
