Provides an introduction to this special issue. Summarizes the process of topic selection, article format, and topic sequence. (GCP)

Argues that Weinrach et al. (1998) made unwarranted claims about the number of psychologists publishing in the "Journal of Counseling and Development" during 1978 to 1993 as well as their membership in the American Counseling Association. Discusses methodological and conceptual problems with the Weinrach et al. article and discusses the…

Drawing on papers by the statistician Robert Matthews, this article questions the standard formula for tests of significance used to validate research results, returning instead to the theorem proposed by Thomas Bayes in the eighteenth century, which starts with a subjective assessment of plausibility.

Describes many-facet Rasch analysis, which provides a basis for making fair and meaningful decisions from individual ratings by judges. Gives examples of crossed, nested, and mixed designs to illustrate how a Rasch analysis may be modified to meet the connectivity requirement for comparing facet measures. (SLD)

Studied the analytic problems associated with a design in which one identifiable group is allocated to each treatment condition and members of these groups are measured to assess the intervention. Results from a simulation study underscore the analytic problems associated with these quasi-experimental or group-randomized designs. (SLD)

This meta-analysis examines the effectiveness of functional mathematics instruction, specifically purchasing skill instruction, for individuals with disabilities. Twenty-eight intervention studies were identified and reviewed. Because all studies employed single-subject research designs, a nonparametric procedure, the percentage of nonoverlapping…

This paper discusses the use of single subject controlled experimental designs for investigating the effects of treatment for aphasia. A brief historical perspective is presented, followed by discussions of the advantages and disadvantages of single subject and group approaches, the basic requirements of single subject experimental research, and…

A description of the three fundamental elements of a good research story- the theoretical framework, the methodological framework and the guiding research questions- is given and the process by which the choice of theoretical framework is made is examined.

The ESRC Teaching and Learning Research Programme is expected to produce knowledge of high social scientific quality and practical pedagogic value. It faces, in a particularly acute form, the issue of how confidence in its conclusions can be built. This article begins with some conceptual clarification of the notion of a 'warrant' for research…

This study examined cognitive processing speed through four modalities (auditory-verbal, visual-verbal, visual, and visual-visual) at the end of Grade 1 and how it influences reading and spelling. The subjects were 124 French-speaking children, selected for their contrasting performance on reading and spelling tasks. The children in the first…

The purpose of this study is to meta-analyze the published studies that measure the performance differences in mental chronometric tasks using a behavioral genetic research design. Because chronometric tasks are so simple, individual differences in the time it takes to complete them are largely due to underlying biological and physiological…

All evaluators face the challenge of striving to adhere to the highest possible standards of ethical conduct. Translating the AEA's Guiding Principles and the Joint Committee's Program Evaluation Standards into everyday practice, however, can be a complex, uncertain, and frustrating endeavor. Moreover, acting in an ethical fashion can require…

In 2 experiments, the authors investigated attention control for tasks involving the processing of grammaticized linguistic stimuli (function words) contextualized in sentence fragments. Attention control was operationalized as shift costs obtained with adult speakers of English in an alternating-runs experimental design (R. D. Rogers & S.…

We address the possibility of combining the results from hemodynamic and electrophysiological methods for the study of cognitive processing of language. The hemodynamic method we use is Event-Related fMRI, and the electrophysiological method measures Event-Related Band Power (ERBP) of the EEG signal. The experimental technique allows us to…
