Consistency in characteristics of maternal behavior with different siblings was investigated among 65 economically disadvantaged families, each having two children. Quality of infant/mother attachment was assessed when firstborn children were 12 and 18 months old, respectively, and when secondborn children were 12 months old. When children were 24…

Little experimental research exists concerning third party mediation. Possible dimensions for study are type of control, including outcome control (of the third party over negotiation outcomes) and process control (third party influence on the negotiation process); and type of intervention, i.e., process or issue oriented interventions. To examine…

It is suggested that models of human problem solving are useful in the analysis of word fluency (WF) test performance. In problem-solving terms, WF tasks would require the subject to define and clarify the conditions of the task (task acquisition), select and employ appropriate strategies, and monitor one's performance. In modern neuropsychology,…

Simple and complex addition problems were presented for true/false verification to 30 undergraduate students to test a general model for cognitive addition. Problems were presented on a microcomputer, with reaction time (RT) and response accuracy recorded. Models for addition were fit to average RT data using multiple regression techniques. These…

Chemists have bemoaned for years their students' inability to solve problems in introductory chemistry courses. However, at least part of this inability must be attributed to the fact that chemists have historically tried to teach their students to solve problems by doing nothing more than working examples. In recent years, chemists have begun to…

This discussion of some of the research literature that is relevant to the issue of teaching thinking provides descriptions of hypothetical, ideal thinkers, and problem solvers; considers the problem of teaching thinking and problem solving; and explores the issue of evaluating programs so that they can be revised and improved. Following Bransford…

First-, third-, fifth-, and sixth-grade children were administered 20 relational reasoning problems in which they had to deduce the possible sizes of one item relative to two others on the basis of a visual comparison and a written clue. Dramatic differences were observed between fifth- and sixth-grade children. Corrective feedback improved…

How the author moved from concern about research to development of prescriptive models of heuristic problem solving and the exploration of metacognition and belief systems is discussed. Student beliefs about problem solving, and their corollaries, are included. (MNS)

Forty toddlers, 1 1/2 to 3 1/2 years of age, and 8 adults, searched for stickers that were hidden underneath two discretely different classes of objects embedded in arrays containing several classes. Study results suggest that the children appear to have been attempting to determine which kinds of choices were the wrong ones. (Author/RWB)

Discusses three major motivations for in-house library research--planning, problem solving, and staff development--in terms of the functions and responsibilities of library management. Ten stages in a research project are identified and management contribution to each is described. It is concluded that the role of management is critical.…

This study describes strategies fifth- and sixth-grade children used to solve the problem of determining how to control a "vehicle" they "drove" by pressing particular keys on a computer. The problem involves identifying or discovering a set of cause-effect relationships. (Author/JN)

Presents perspectives on methodological assumptions underlying research efforts in artificial intelligence (AI) and charts activities, motivations, methods, and current status of research in each of the major AI subareas: natural language understanding; computer vision; expert systems; search, problem solving, planning; theorem proving and logic…

Determined effects of two task types on 12- and 13-year-olds' understanding of applications of multiplying and dividing positive numbers. Results indicate the persuasive nature of certain misconceptions and specific effects of context attributable to such aspects as relative familiarity. Implications of these and other results are discussed.…

Provides framework for assessing the extent to which problem-solving skills learned through LOGO, a children's graphics-oriented-structured computer language, may be transferred to other contexts. Examines principles governing generalization of learning. Discusses learning transfer and components of the LOGO experience that may affect transfer.…

The key to the success of decision support systems will be the way that institutional researchers integrate the variety of specific and personal systems into a viable and coordinated institutionwide system. (Author/MLW)
