An eyetracking study testing D. L. Medin and M. M. Schaffer's (1978) 5-4 category structure was conducted. Over 30 studies have shown that the exemplar-based generalized context model (GCM) usually provides a better quantitative account of 5-4 learning data as compared with the prototype model. However, J. D. Smith and J. P. Minda (2000) argued…

Sutherland and Singh (2004) focus on the relationship between students' inappropriate behaviors and academic failure, articulating how this relationship may be mediated by learned helplessness in a reciprocally negative reinforcing cycle. In responding to their work, the authors suggest a thread of disciplined inquiry and contextual framework for…

This article explores relationships between designing and making in the work of children within the age range 5-11 when engaged in practical modelling tasks. The notion of the model is explored from the perspective of concrete representations. It is suggested that concrete models may be used as hypotheses from which to test ideas about the nature…

In today's knowledge economy, technology is utilized more than ever to deliver instructional material to the learner. Nonetheless, information may not always be presented in a manner that maximizes the learning experience, resulting in a negative impact on learning outcomes. Drawing on the Task-Technology Fit model, a research framework was…

The microcomputer offers social science field researchers a valuable tool for managing qualitative research data. In addition to the flexibility and efficiency of the microcomputer, the logic governing its programming and operation imposes a framework on the research process which necessitates that research decisions and strategies be explicit and…

This report describes the application of a shell expert system from the medical diagnostic system, Neomycin, to Caster, a diagnostic system for malfunctions in industrial sandcasting. This system was developed to test the hypothesis that starting with a well-developed classification procedure and a relational language for stating the…

Histories of media research commonly assume that models of mass media effects have progressed from direct or hypodermic effect models to indirect or multi-step models. Recently, however, B. Reeves and E. Wartella have objected to this assumption. To evaluate their alternative hypotheses, 163 studies from over 88 sources, representing nearly a…

Arguing that sufficient theory exists about the interplay between human information processing, computer systems, and the demands of various tasks to construct useful theories of human-computer interaction, this study presents a structural model of human-computer interaction and reports the results of various statistical analyses of this model.…

AN ATTEMPT IS MADE TO ESTABLISH A THEORETICAL FOUNDATION FOR GROUP PROPERTY AND LIABILITY INSURANCE AND TO ADVANCE THE GENERAL HYPOTHESIS THAT THE PRINCIPLES USED IN INSTALLING AND ADMINISTERING GROUP LIFE AND HEALTH INSURANCE ARE APPLICABLE TO THE INSTALLATION AND ADMINISTRATION OF GROUP PROPERTY AND LIABILITY INSURANCE. A SURVEY WAS CONDUCTED TO…

This paper presents an integrative theoretical framework for the conceptualization of the marriage relationship in terms of Kelly's psychology of personal constructs. Personal construct theory offers a productive model which can account for research findings related to most of the variables found to be relevant to marital success. Personal…

The hypothesis that the correlation of measures on the same characteristic at two points in time will approach unity when the relevant, intervening environment is added to the prediction equation is tested on a sample of high school physics students. (Author/AG)

Review of rural social work literature of the 1970's indicates research has primarly followed the naturalistic model defined by Taylor, rather than the positivist approach favored by Fischer. Discussed are: surveys and case studies; ethnographies; participatory/action research; historical research; positivistic research; hypothesis testing…

One-hundred two undergraduates studied a thematic map and read related text, with the order of presentation varied and half receiving a verbal prime related to the theme. Map-first students recalled more and made more correct inferences. Verbal priming did not affect theme-related recall or inference. (SLD)

Compares the perceptions of Malaysians and Australians for four Web site design characteristics--atmospherics, news stories, signs, and products and services--as part of the integrated Internet marketing model. Hypothesizes that the predominant culture is not generalized to another culture, discusses validity and reliability, and suggest further…
