Many "if p, then q" conditionals have decision-theoretic features, such as antecedents or consequents that relate to the utility functions of various agents. These decision-theoretic features leak into reasoning processes, resulting in various paralogical conclusions. The theory of utility conditionals offers a unified account of the various forms…

Previous research has shown that preschoolers extend labels and internal properties of objects based on those objects' causal properties, even when the causal properties conflict with the objects' perceptual appearance [Nazzi, T., & Gopnik, A. (2000). "A shift in children's use of perceptual and causal cues to categorization." "Developmental…

Participants read a series of passages containing an action that required the use of an instrument. In Experiment 1, a naming task failed to detect activation of a target instrument when that instrument was supported in the preceding text. In Experiment 2, reading times were slow on a target sentence that contradicted the inferential information,…

Psychologists have long been captivated by the perception of animacy--the fact that even simple moving shapes may appear to engage in animate, intentional, and goal-directed movements. Here we report several new types of studies of a particularly salient form of perceived animacy: "chasing", in which one shape (the "wolf") pursues another shape…

Two models for the analysis of longitudinal binary data are discussed: the marginal model and the random intercepts model. In contrast to the linear mixed model (LMM), the two models for binary data are not subsumed under a single hierarchical model. The marginal model provides group-level information whereas the random intercepts model provides…

Comprehension strategies, while helpful, are not sufficient to produce student achievement at high levels. The authors examine the role of background knowledge and vocabulary in developing understanding and facilitating achievement. Through purposeful instruction in vocabulary and by building and activating background knowledge, teachers can help…

Preschoolers' causal learning from intentional actions--causal interventions--is subject to a self-agency bias. The authors propose that this bias is evidence-based, in other words, that it is responsive to causal uncertainty. In the current studies, two causes (one child controlled, one experimenter controlled) were associated with one or two…

This article recounts an attempt by administration and faculty to create a multinational and multicultural vision for Tel Hai Academic College in the Galilee in Israel. This uncommon initiative in the Israeli academia intends to transform the campus into a unique academic institution allowing equality and visibility for all cultural and national…

The problem identified in this quantitative descriptive study is that many Wisconsin Evangelical Lutheran Synod Lutheran Elementary Schools (WELS LES) are not adequately prepared to teach all students with special needs. The purpose of the study was to identify principals' perceptions of, and potential barriers to, the successful implementation of…

In the arena of educational testing, accessibility refers to the degree to which students are given the opportunity to participate in and engage a test. Accessibility theory is a model for examining the interactions between the test-taker and the test itself and defining how they may decrease some students' access to the test event, ultimately…

Beginning with a reference to living in a time of both uncertainty and opportunity, this article presents a discussion of key areas where shared understanding is needed if we are to successfully realize the design and use of high quality, valid assessments of science. The key areas discussed are: (1) assessment purpose and use, (2) the nature of…

Effective practices in student data collection and implementation of data-based instructional decisions are needed for all educators, but are especially important when students have severe intellectual and developmental disabilities. Although research in the area of data-based instructional decisions for students with severe disabilities shows…

The conventional approaches to mediation analysis such as path analysis and structural equation modeling typically involve specifying two structural models, one for the mediator and the other for the outcome. We employ an alternative approach that avoids some strong identification assumptions invoked by the conventional approaches. By applying a…

Biomedical research has produced vast amounts of new information in the last decade but has been slow to find its use in clinical applications. Data from disparate sources such as genetic studies and summary data from published literature have been amassed, but there is a significant gap, primarily due to a lack of normative methods, in combining…

Much recent work in natural language processing treats linguistic analysis as an inference problem over graphs. This development opens up useful connections between machine learning, graph theory, and linguistics. The first part of this dissertation formulates syntactic dependency parsing as a dynamic Markov random field with the novel…
