In the present study, we used a modeling approach for measuring task conflict in task switching, assessing the probability of selecting the correct task via multinomial processing tree (MPT) modeling. With this method, task conflict and response conflict can be independently assessed as the probability of selecting the correct task and the…

Childhood adversity can lead to cognitive deficits or enhancements, depending on many factors. Though progress has been made, two challenges prevent us from integrating and better understanding these patterns. First, studies commonly use and interpret raw performance differences, such as response times, which conflate different stages of cognitive…

This article addresses performance assessments that involve collaboration among students. We apply the Hawkes process to infer whether the actions of one student are associated with increased probability of further actions by his/her partner(s) in the near future. This leads to an intuitive notion of engagement among collaborators, and we consider…

User modelling algorithms such as Performance Factors Analysis and Knowledge Tracing seek to determine a student's knowledge state by analyzing (among other features) right and wrong answers. Anyone who has ever graded an assignment by hand knows that some answers are "more wrong" than others; i.e. they display less of an understanding…

We integrated the unfolding model of turnover, job embeddedness theory and affective events theory to build and test a model specifying the relationship between negative shocks, on-the-job embeddedness and important employee behaviors. The results showed that embeddedness mediates the relationship between negative shocks and job search behaviors…

Looking beyond the right or wrong answer is imperative to the development of effective educational environments conducive to Pre-AP work in math. This presentation explores a system of evaluation in math that provides a personalized, student-reflective model correlated to consortia-based assessment. Using examples of students' work that includes…

Student modeling is a fundamental concept applicable to a variety of intelligent tutoring systems (ITS). However, there is not a lot of practical guidance on how to construct and train such models. This paper compares two approaches for student modeling, Knowledge Tracing (KT) and Performance Factors Analysis (PFA), by evaluating their predictive…

Psychological researchers should deal with the concrete stimulus-response principles of learning on which behavior is based, and study behaviors that are representative of real life behaviors. The present research strategy has come from two faulty ideas: first, a concern with underlying, inferred mental processes, rather than with actual tasks or…

Most accounts of the Stroop effect (Stroop, 1935) emphasize its negative aspect, namely, that in particular situations, processing of an irrelevant stimulus dimension interferes with participants' performance of the instructed task. In contrast, this paper emphasizes the fact that, even with that interference, participants actually can (and…

Contributions of rule, attribute, and complete learning to solution of low (conjunctive) and high (conditional) level concept attainment problems were assessed in 2 experiments. Direct learning and transfer of models was compared with vicarious learning and transfer of observers. Subjects in the latter condition observed yoked models solve the…

A case is made that typing, speaking, and playing music are members of a family of skills that can be studied within a common theory. (Editor)

Differences in performance with various stimulus-response mappings are among the most prevalent findings for binary choice reaction tasks. The authors show that perceptual or conceptual similarity is not necessary to obtain mapping effects; a type of structural similarity is sufficient. Specifically, stimulus and response alternatives are coded as…

The purpose of this study was to investigate within the vicarious learning paradigm the effects of manipulated self-evaluation treatments and model performance conditions on both the acquisition and subsequent performance of novel and self-reinforcing responses. It was predicted that subjects receiving either high or low self-evaluation treatments…

Studies the effects of anger arousal, displays of aggression, and pain cues on later interpersonal aggression. The hypothesis that symbolic aggression has a cathartic effect is contradicted by the results. Bibliography, table, and graphs. (JB)
