Recency effects (REs) have been well established in memory and probability learning paradigms but have received little attention in category earning research. Extant categorization models predict REs to be unaffected by learning, whereas a functional interpretation of REs, suggested by results in other domains, predicts that people are able to learn(More)
Exemplar and connectionist models were compared on their ability to predict overconfidence effects in category learning data. In the standard task, participants learned to classify hypothetical patients with particular symptom patterns into disease categories and reported confidence judgments in the form of probabilities. The connectionist model asserts(More)
This paper describes a tool for anticipating cultural behavior called, " CulBN. " The tool uses Bayesian belief networks to represent distributions of causal knowledge spread across members of cultural groups. CulBN simulations allow one to anticipate how changes in beliefs affect decisions and actions at the cultural level of analysis. An example case from(More)
An inherent challenge in understanding behavior in other cultures rests in gathering, analyzing, and representing the relevant cultural concepts, beliefs, and values that drive decisions in those populations. In this chapter, we present Cultural Network Analysis (CNA) as a broad approach that aids in providing the most relevant cognitive aspects of cultural(More)

Information operations (IO) specialists are like US political strategists in foreign lands, and they are concerned with affecting others' decision processes. In order to be effective, IO practitioners must be able to efficiently develop an understanding, frame or theory (i.e. " make sense ") about how decisions are made in a particular locale. As in(More)
Many of us share a strong intuition that justification forces us to better understand the situations we face. And there is substantial evidence indicating that this is often the case. However, there is a growing body of research showing that, under certain circumstances, explanation and justification can impair performance on a variety of cognitive tasks.(More)
OBJECTIVE The goals of this study were (1) to determine the prevalence of child maltreatment in hospitalized children and adolescents with developmental disabilities and concomitant psychiatric disorders, and (2) to identify the contribution of specific mother and child characteristics to the use of more severe disciplinary practices by mothers.
