Bayesian approach is becoming increasingly important as it provides many advantages in dealing with complex data. However, there is no well-defined model selection criterion or index in a Bayesian context. To address the challenges, new indices are needed. The goal of this study is to propose new model selection indices and to investigate their…

Composite scores are an exceptionally important psychometric tool for behavioral science research applications. A prototypical example occurs with self-report data, where researchers routinely use questionnaires with multiple items that tap into different features of a target construct. Item-level missing data are endemic to composite score…

Numerous forms and meanings of validity have been developed to provide researchers with the opportunity to assess the many potential sources of ambiguity that exist in any research finding. A Validity Network Schema (VNS) developed by Brinberg & McGrath (1982) is extended and elaborated in order to describe the components of the research…

This review of studies comparing early childhood education models focuses on the trends and problems of this kind of research. The 8 "qualitative" studies reviewed, all pertain to aspects of instructional theory centering around teacher-child interaction. In the 19 empirical studies discussed, a dichotomy between "structured and unstructured…

K. Burke's (1945) pentad identifies five contributing factors in any communication event: agent, purpose, act, scene, and agency. Using the pentad as an organizational schema, this paper summarizes problems in methods used by behavioral researchers to study the deceptive communication event. The paper argues that fragmenting the communication act…

Summarizes Karl Weick's Model of Organizing including its advantages and limitations and tests one of the claims fundamental to Weick's argument. (MH)

In educational research, nonessential factors are commonly ignored and when accounted for, they are often treated statistically as fixed effects. Yet many researchers in these situations generalize their findings beyond the specific levels selected; however, the analyses may require treating the factor as a random effect. Such inappropriate…

Psychological researchers should deal with the concrete stimulus-response principles of learning on which behavior is based, and study behaviors that are representative of real life behaviors. The present research strategy has come from two faulty ideas: first, a concern with underlying, inferred mental processes, rather than with actual tasks or…

Critical features of sound observational studies fall under three categories: the sampling framework; the theoretical model; and the statistical procedure. If the methodology for explanatory, rather than descriptive, observational studies can be applied within these categories, more consistent, convincing, useful explanations of educational…

Laboratory simulations combine the strengths of lab experiments and field studies while avoiding many of their liabilities. They permit the emotional involvement, the time needed for development of norms and interlocked systems of interaction, and the broad range of variables typical of field settings, yet allow for experimental controls and…

This paper indicates underlying philosophic assumptions which are compatible with the behavior analysis approach to child development. Four issues taken into consideration are (a) biology and environment, (b) structure and function, (c) traits and situations, and (d) mechanistic and organismic approaches to development. The following ideas…

This presentation describes research on families with mentally retarded children, focusing on trends since 1983, the year that family research issues were reconceptualized in a paper titled "A Model of Stress, Coping, and Family Ecology" by Keith Crnic and others. The trend analysis concentrates on four issues: (1) the magnitude of the impact of…
