We will first argue that there is a natural fit between the two on the ontological level. On the methodological level, we will demonstrate in what ways…

In the current study, momentary time sampling (MTS) and partial-interval recording (PIR) were compared to continuous-duration recording of stereotypy and to the frequency of self-injury during a treatment analysis to determine whether the recording method affected data interpretation. Five previously conducted treatment analysis data sets were…

A common problem in the behavioral sciences is to determine if a set of observed variables can be more parsimoniously represented by a smaller set of derived variables. To address this problem, the performance of five methods for determining the number of components to retain (Horn's parallel analysis, Velicer's Minimum Average Partial (MAP),…

A discussion of in-depth interviewing as a method for research on language teaching and learning situates the technique within the continuum of research methodology and differentiates it from quantitative research methods. The strengths and weaknesses of in-depth interviewing are examined, methods of sampling are discussed, and advice on the…
