In science in general and in the context of single-case experimental designs, replication of the effects of the intervention within and/or across participants or experiments is crucial for establishing causality and for assessing the generality of the intervention effect. Specific developments and proposals for assessing whether an effect has been…

Publication bias arises when studies with favorable results are more likely to be reported than are studies with null findings. If this bias occurs in studies with single-subject experimental designs (SSEDs) on applied behavior-analytic (ABA) interventions, it could lead to exaggerated estimates of intervention effects. Therefore, we conducted an…

We reviewed all research articles in 10 recent volumes of the "Journal of Applied Behavior Analysis (JABA)": Vol. 28(3), 1995, through Vol. 38(2), 2005. Continuous recording was used in the majority (55%) of the 168 articles reporting data on free-operant human behaviors. Three methods for reporting interobserver agreement (exact agreement,…

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…

A survey of articles in the "Journal of Applied Behavior Analysis" (1968-1980) demonstrated that the majority of articles published do not use any assessment of the actual occurrence of the independent variable and a sizable minority do not provide operational definitions of the independent variable. The feasibility and utility of ensuring the…

The job of a researcher is to explain the phenomenon that he or she is seeking to understand. To do this requires the accumulation of facts. These facts are then interpreted to arrive at explanations. However, individual researchers often interpret facts in different ways and arrive at disparate explanations. In her book, Making Sense of Life,…

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.

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…

Four criteria for evaluating the appropriateness of units of analysis for task analytic research are proposed. Meeting all four criteria and thus recommended for use in behavior analytic work is percentage correct with competent performance coded and a task analysis grid showing individual step performance.

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,…

Emphasis on technological precision and methodological sophistication in the field of applied behavior analysis has brought about a deemphasis of theoretical and philosophical concerns. For theoretical development of the field to move ahead, applied behavior analysts must develop the principles needed to describe ways of predicting and controlling…

Performance feedback has facilitated the acquisition and maintenance of a wide range of behaviors (e.g., health-care routines, seat-belt use). Most researchers have attributed the effectiveness of performance feedback to (a) its discriminative functions, (b) its reinforcing functions, or (c) the combination of the two. In this study, we attempted…

This essay discusses the significance functional analysis has had for applied behavior analysis of aberrant behavior. The methodology has lessened the field's reliance on default technologies and promoted analysis of environment-behavior interactions maintaining target responses as the basis for selecting treatments. It has also contributed to the…

Teachers of 2 children (ages 7 and 13) with autism were trained to conduct a descriptive analysis and a classroom experimental analysis of aberrant behavior. Each procedure identified negative reinforcement as a maintaining variable for aberrant behavior. Intervention based on the assessment was successfully implemented with one child and had…

To the extent that applied behavior analysis represents a scientific and practical approach to the study of behavior, its technological character is essential. The most serious problem evident in the field is not that the research being done is too technical but that more good research of all types is needed. (JDD)
