The need for humanistically-oriented research may be viewed as the unfinished business of humanistic psychology. Additional research is needed to support some of the theoretical positions of humanistic psychology which have emerged from clinical practice, education, and management consultation rather than from laboratories and field studies. The…

Individuals often estimate the probability of future events by the ease with which they can recall or cognitively construct relevant instances. Previous research has not precisely identified the cognitive processes mediating this "availability heuristic." Two potential mediators (imagery of the event, perceived reasons or causes for the…

The emerging concept of program theory and its function in program evaluation practice is the central focus of this paper. It appears that the traditional decision/adoption model, when considered in conjunction with the institutionalized beliefs, values, and methodological procedures of the state Cooperative Extension Services, meets the criteria…

Provides a brief introduction to the basics of artificial intelligence and expert systems and explains terms in general use. (CLB)

Defines the engineering method by: (1) giving a preliminary definition and examples of its essential term (heuristics); (2) comparing the definition to a popular alternative; and (3) presenting a simple form of the definition. This definition states that the engineering method is the use of engineering heuristics. (JN)

Discusses factors that interfere with students' effective use of heuristic procedures for invention in composition. (HTH)

The algo-heuristic theory is concerned with identifying unobservable cognitive processes and their unconscious component cognitive operations, including learning how to describe them algorithmically and heuristically, and how to devise specific instructional tools (algorithmic and heuristic) to develop cognitive processes much faster. (BW)

This paper outlines two types of discriminant analysis, predictive discriminant analysis (PDA) and descriptive discriminant analysis (DDA). Important differences between PDA and DDA are introduced and discussed using a heuristic data set, specifically indicating the portions of the Statistical Package for the Social Sciences (SPSS) output relevant…

This paper considers the use of heuristic methodology as a research vehicle for new science investigations in education. The paper describes heuristic methodology and its use as a means of new science-based research in schools. It also describes how heuristic methodology was used in a 2002 study to explain educational practices through the…

Discusses algorithmic problem solving in computer science education, particularly algorithmic insight, and focuses on the relevance and effectiveness of the heuristic simplifying constraints which involves simplification of a given problem to a problem in which constraints are imposed on the input data. Presents three examples involving…

Discussion of Web linking behavior and how to define a Web document focuses on a study of United Kingdom university Web sites that investigated the association between research productivity of the university and the number of incoming links from its peers' Web sites. Defines three alternative heuristics for counting links. (LRW)

Proposes a mathematical model to explain the observed concentration or diversity of nominal classes in information retrieval systems. The Lorenz Curve is discussed, Information Production Process (IPP) is explained, and a heuristic explanation of circumstances in which the model might be used is offered. (30 references) (LRW)

Three experienced and eight novice physicians were asked to solve three problems. Results indicated that the ability to incorporate contextual information contributed to effective solutions. Experienced physicians tended to use more inclusive approaches, although both groups demonstrated premature diagnostic bias. (SK)

Demonstrates how the tragedy of the 1986 space shuttle "Challenger" provides an example of how communication through memos and letters concerning O-ring problems went awry. Presents some methods by which the technical writing teacher might incorporate this material into their writing curricula. (HB)

Examines tasks from the heuristics and biases literature in light of the understanding/acceptance principle of P. Slovic and A. Tversky (1974). Shows how the variation and instability of responses can be analyzed to yield inferences about why descriptive and normative models of human reasoning and decision making sometimes do not coincide.…
