This article presents a discussion of mixed methods (MM) sampling techniques. MM sampling involves combining well-established qualitative and quantitative techniques in creative ways to answer research questions posed by MM research designs. Several issues germane to MM sampling are presented including the differences between probability and…

A major debate exists in the neuropsychology community concerning whether case study is preferable to group study of brain-damaged patients. So far, the discussion has been limited to the advantages and disadvantages of both methods, with the assumption that neurolinguists pursue a single goal attainable by one or the other method. Practical…

This paper describes the parallel treatments design, a nested single subject experimental design that combines two concurrently implemented multiple probe designs, allows control for effects of extraneous variables through counterbalancing, and replicates its effects across behaviors. Procedural guidelines for the design's use and issues related…

Analog baselines are an experimental methodology for identifying the functions of maladaptive behavior of individuals with developmental disabilities in naturally occurring environments. This article identifies potential limitations of this methodology, including: fidelity of baseline design conditions, a narrow analysis of behavior, and limited…

This article reviews 66 studies which used applied behavior analysis to change the behaviors of students with visual disabilities. It documents the participants, targeted behaviors, procedures used, outcomes, and follow-up. The article offers recommendations for future researchers on the selection of subjects, target behaviors, appropriate…

Studies (N=168) describing the use of behavioral interventions with behavior-disordered students were analyzed in terms of their reporting on four classes of marker variables: descriptive, substantive, topical, and background. Data showed that more thorough descriptions of research populations are required in the areas of selection criteria,…

This article examines the status of behavioral research on genetic mental retardation syndromes and finds that the field continues to struggle with three methodological issues: (1) how to think about control or contrast groups, (2) the interplay of behavioral phenotypes with development and other within-group variations, and (3) the efficacy of…

In behavior research using cognitive and affective measures, there is often incongruity between the statistical analysis employed and the intended inference. This paper argues that incorporating items as levels of a random facet via generalizability theory allows the statistical examination of the inferential question in the desired universe of…

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…

The complexity of the school consultation field points to the need for review of the current state of the field. To further understanding of the content and methodology utilized in consultation research, a content analysis of research articles published over the last 12 years considered the following areas: type of consultation, subject matter,…

This paper reports the results of a Monte Carlo investigation of Type I errors in the single group repeated measures design where multiple measures are collected from each observational unit at each measurement occasion. The Type I error of three multivariate tests were examined. These were the doubly multivariate F test, the multivariate mixed…

Describes a study using self-report measures of students' responses to auditory and visual stimuli to measure distractibility in task performance among 224 Canadian undergraduates. Findings show the absence of any link between self-reported distractibility and actual performance. Study shows correlations between personality type and…
