Preknowledge cheating jeopardizes the validity of inferences based on test results. Many methods have been developed to detect preknowledge cheating by jointly analyzing item responses and response times. Gaze fixations, an essential eye-tracker measure, can be utilized to help detect aberrant testing behavior with improved accuracy beyond using…

Changepoints are abrupt variations in a sequence of data in statistical inference. In educational and psychological assessments, it is pivotal to properly differentiate examinees' aberrant behaviors from solution behavior to ensure test reliability and validity. In this paper, we propose a sequential Bayesian changepoint detection algorithm to…

This study investigated the effects of 15 second client response latencies upon the speech and silence behavior of four experimentally naive counselors in advanced training. The results indicate that a coached client was able to effect change unobtrusively in the speech and silence behavior of counselors. (Author)

Curricula for students with autism do not take into account levels of learning such as behavioral fluency. Behavioral fluency addresses accuracy as well as speed of response. We posit that fluency increases the functionality of skills for students with autism and should be systematically programmed into a curriculum. To discuss the application of…

Certain characteristics of a Taylor (1965) competitive reaction time task contribute to a lack of awareness of contingencies that exist between two aggressors. The opponent's contingent response to the subject's specific shock setting may be obscured by the reaction time competition, thus concealing the matching contingency. Nine separate steps…

Response latency was studied as a measure of associative strength or degree of learning and possible basis for instructional decision making in computer-assisted instruction. Latency was investigated in a paired-associate task as a function of training procedure and information transmission requirements during acquisition and overlearning. The…

This study was designed to determine the relationship between children's reflection-impulsivity and responses to a forced choice of a toy for play (labelled as impulsivity) and the length of continued play with the selected toy (labelled as latency). A group of twenty four-year-olds, male and female, were observed making a choice between toys. The…

A study involving eight boys with autism and eight boys with Down syndrome (ages 6-10) with similar adaptive behavior levels used an ecological approach to study the in-depth structure of the behavior stream. Narrative records were collected and analyzed based on duration and frequency of behaviors. Each record was analyzed by marking the behavior…
