The primary objective of this investigation is the formulation of random intercept latent profile transition analysis (RI-LPTA). Our simulation investigation suggests that the election between LPTA and RI-LPTA for examination has negligible impact on the estimation of transition probability parameters when the population parameters are generated…

This special issue is devoted to describing and evaluating new methods for analyzing online writing processes in a second language (L2). As all the contributors have stated, the aim is to identify the cognitive processes underlying writing. The ultimate aim is to employ observations and experimental manipulations of these processes to build…

Individuals with Prader-Willi syndrome (PWS) are at risk for excessive daytime sleepiness (EDS) and disruptive behavior. This pilot study explores temporal characteristics of EDS and severe disruptive behavior across time of day and day of week in seven individuals with PWS (aged between 33 and 49 years) of whom five were matched to controls.…

This paper is principally about methodology. It first summarizes five issues in the emerging research agenda of conversation analysis-for-second language acquisition (CA-for-SLA), and develops empirically based analyses of classroom talk that occurs over several days and months to illustrate how a longitudinal learning behavior tracking (LBT)…

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 new methods for modeling the strength of association between multiple behaviors in a behavioral sequence, particularly those involving substantively important interaction patterns. Modeling and identifying such interaction patterns becomes more complex when behaviors are assigned to more than two categories, as is the case…

This review critically examines the research findings which characterize the cognitive, behavioral, and neuroanatomical features of Williams syndrome (WS). This article analyzes 178 published studies in the WS literature covering the following areas: 1) General intelligence, 2) Language skills, 3) Visuospatial and face processing skills, 4)…

A two-step procedure is proposed for detecting behavioral patterns in observational data in evaluation research. Latent class analysis is used to derive a classification of single observations at the variable level. The second step uses the probabilities that each observation falls into latent classes to derive behavioral preference scores. (SLD)

Noting that there is growing interest in systematic, ethnographic studies of mass media and their primary audiences (families), this paper seeks to encourage additional ethnographic study of audience behavior by discussing some theoretical concerns that bear on the qualitative research enterprise. To do this, the paper first introduces a variety…

As part of a research program designed to explicate the construct "power," a formulative research strategy was used to identify 37 personal orientations toward power. A preliminary instrument based on these orientations was administered to samples of corporate executives, government employees, law enforcement personnel, and sales associates. A…

Reviews previous work in training observers for collecting observational counseling data. Outlines a nine-step Systematic Rater Training Model, which includes overview and contract, concept presentation, stimulation, modeling, passive discrimination, active discrimination, production, transfer of training to performance, and ongoing evaluation.…

Uses genre and genre repertoire to investigate a community's structuring of communicative practices. Examines communications exchanged by a group of distributed knowledge workers in a multiyear, interorganizational project conducted primarily through electronic mail. Results reveal rich, varied communications shaped in response to community norms,…

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…

In finding an accurate method of describing school administrators' behavior patterns, draws on script theory from cognitive psychology and speech act theory from sociolinguistics to supplement the structured observation approach. (JW)

The reliability of visual inspection in single-case research was investigated by determining agreement among 5 judges visually inspecting 44 graphs depicting behavior from baseline to intervention. Agreement between visual inspection and statistical procedures was determined. Implications for single-case research are discussed. (SLD)
