The Lognormal Response Time (LNRT) model measures the speed of test-takers relative to the normative time demands of items on a test. The resulting speed parameters and model residuals are often analyzed for evidence of anomalous test-taking behavior associated with fast and poorly fitting response time patterns. Extending this model, we…

The overriding aim of this study was to conduct a side-by-side comparative evaluation of two online suicide prevention gatekeeper-training programs: Question, Persuade, Refer (QPR) and Making Educators Partners in Youth Suicide Prevention (MEP). Specific aims included identifying program components, instructional methods, and technology elements…

Person-fit analyses are commonly used to detect aberrant responding in self-report data. Nonparametric person fit statistics do not require fitting a parametric test theory model and have performed well compared to other person-fit statistics. However, detection of aberrant responding has primarily focused on dominance response data, thus the…

With the advancements in technology and the growing demand for online education, Virtual Learning Environments (VLEs) have experienced rapid development in recent years. This demand was especially evident during the COVID-19 pandemic. The incorporation of new technologies in VLEs provides new opportunities to better understand the behaviors of…

In high-stakes, large-scale, standardized tests with certain time limits, examinees are likely to engage in either one of the three types of behavior (e.g., van der Linden & Guo, 2008; Wang & Xu, 2015): solution behavior, rapid guessing behavior, and cheating behavior. Oftentimes examinees do not always solve all items due to various…

We investigated changes in bias (preference for one response alternative) in signal detection when relative reinforcer frequency for correct responses varied across sessions. In Experiment 1, 4 rats responded in a two-stimulus, two-response identification procedure employing temporal stimuli (short vs. long houselight presentations). Relative…

The present study examined the joint development of substance use and externalizing problems in early and middle adolescence. First, it was tested whether the relevant groups found in previous studies i.e., those with an early onset, a late onset, and no onset or low levels of risk behavior could be identified, while using a developmental model of…

Background: Clinical heterogeneity of autism likely hinders efforts to find genes associated with this complex psychiatric disorder. Some studies have produced promising results by restricting the sample according to the expression of specific familial factors or components of autism. Previous factor analyses of the restricted, repetitive…

The contributions of specific scales of the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) to the classification of 180 adolescent substance abusers into groups characterized by aspects of behavioral control were studied. Seven scales made significant contributions to the classification of substance abusers into three groups, with…

This paper focuses on the systems approach in family therapy and attempts to further the development of this approach by defining its assumptions and delineating the relationship between the assumptions and their operationalization in assessment and therapy. The first section identifies two basic assumptions of a systemic approach, i.e., that the…

The booklet describes a precision teaching program for the remediation of children with learning deficits in grades K-12 which enables the teacher to use an accurate means of describing and measuring performance on a direct and daily basis and provides a behavioral formula for programing and analyzing social and academic behavior, interpreting…
