Visual inspection of data is a common method for understanding, responding to, and communicating important behavior-environment relations in single-subject research. In a field that was once dominated by cumulative, moment-to-moment records of behavior, a number of graphic forms currently exist that aggregate data into larger units. In this…

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…

The use of multivariate statistics in behavioral research is investigated, with emphasis on the reasons why multivariate methods can be so important. The concepts of testwise and experimentwise error are explained, and it is noted that multivariate methods can be used to control the inflation of experimentwise Type I error. It is also noted that…

This introductory article introduces papers that present examples of neuroimaging applications in the field of communication sciences and disorders. It notes that neuroimaging studies were usually an outgrowth of earlier behavioral research or clinical observations with knowledge of the disorder's behavioral characteristic critical to development…

This paper is an introduction to behavioral genetics for researchers and practitioners in language development and disorders. It identifies essential concepts and applies behavioral genetic research to the language sciences. It suggests that more complex questions may be successfully addressed through behavioral genetic paradigms. Research needs…

This response to a paper by Guess and Carr (EC 602 212) on stereotypy and self-injury in the disabled evaluates their interpretation of the literature, use of conceptual terms, and treatment of behavior analysis principles. They are critiqued for using descriptive analogies and intervening variables to support their theory. (DB)

Differing theoretical approaches to the study of emotions are presented: emotions as private (psychodynamic approaches); emotions as sociocultural phenomena (social constructionist approaches); and a third perspective (interactionist approaches) transcending these two. These approaches have important methodological implications in studying…

This review of 50 social validation research studies involving persons with handicaps concludes that social validation procedures are an appropriate and important component of applied behavior analysis. Discussed are methodological issues, social importance of effects, social significance of goals, social appropriateness of procedures, and…

This paper argues that behavior analysis is not technological to a fault, but rather has a faulty technology by being incomplete. The paper examines reinforcers and punishers that result from the outcomes of either (1) striving for better experimental control, or (2) inventing theories to explain why current control is imperfect. (JDD)

A review of 158 applied behavior analysis studies with children as subjects, published in the "Journal of Applied Behavior Analysis" between 1980 and 1990, found that (1) 16% measured the accuracy of independent variable implementation, and (2) two-thirds did not operationally define components of the independent variable. Specific recommendations…

This literature review addresses the technical adequacy of time sampling observation systems, which is fundamental to ensuring the generalizability of data obtained from behavioral observation. Investigations comparing partial interval, whole interval, and momentary time sampling have yielded consistent results. These suggest that duration of…

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…

Criticizes an earlier essay that questioned the validity of contemporary educational research practices, especially those involving experimentation. Argues that research using experimentation is valid and can lead to new and generalizable knowledge. (FMW)

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…

This commentary summarizes methodological and conceptual issues in functional analysis methodologies and offers some suggestions for their resolution. Considered are increasing complexity, absence of contingencies during assessment, use of subtle manipulations, alternative assessment strategies, analysis of antecedent influences on behavior,…
