Background: Historically, significant advances in scientific understanding have followed advances in measurement and observation. As the resolving power of an instrument increased, so have gains in the understanding of the phenomena being observed. Modern interactive systems are potentially the new "microscopes" when they are…

The three algorithms most frequently selected by behavior-analytic researchers to compute interobserver agreement with continuous recording were used to assess the accuracy of data recorded from video samples on handheld computers by 12 observers. Rate and duration of responding were recorded for three samples each. Data files were compared with…

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…

Considers the distinction between voluntary and involuntary unemployment by analyzing six behavioral characteristics attributed to groups of workers suspected of indulging in the former, and the labor market mechanisms supposedly encouraging them. (Author/CT)

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…

This introduction to a special section provides the basic definitions and presents the measurement approaches and data analytic techniques that are collectively referred to as chaos theory. The conceptualization and assessment of unstable behavioral disorders can be strengthened by incorporating elements of chaos theory. (SLD)

Recent studies suggest that the affective domain is just as important to job success and survival as the psychomotor and cognitive domains. This study was designed to compare the rated level of affective work competencies as expressed by workers, supervisors, and vocational educators. The study revealed significant differences among these groups.…

The user-friendly Classroom Ecobehavioral Assessment Instrument was developed to incorporate advantages of environmental assessment and functional assessment. Relatively simple behavior sampling procedures and scripted steps for summarizing and analyzing data lead to prescriptions for altering assessment and/or intervention practices. Results of…

The article presents the results of a data analysis intended to examine the relationship between children's personality, maternal beliefs and childrearing behaviour and various disabilities on the one hand (mildly, moderate or severe mental handicap, sensorial handicap, developmental disabilities) and mothers' educational level on the other. Data…
