Dialects vary in their allophonic patterns, which can affect listeners' phonological and lexical representations. I explore how different exposure to dialect-specific allophonic patterns for two vowels in American English, /ae ai/, affects listeners' lexical processing behaviors across three perception tasks: perceptual similarity, priming, and…

Much of the existing literature on intergroup attitudes in preschool does not look at the intersections of race and gender. Integrating key developmental and social theories, the current study asked 58 diverse preschoolers (31 white, 27 non-white) to make decisions about other children when given only racial and gender information. The…

This study investigated the developmental trajectories of three perceptual domains related to regional dialect competence: the linguistic domain, tested through an intelligibility in noise task; the objective indexical domain, tested through locality judgments and a free classification task; and the subjective indexical domain, tested through…

A critical component of scientific reasoning is the consideration of alternative explanations. Recognizing that decades of cognitive psychology research have demonstrated that relative cognitive accessibility, or "what comes to mind," strongly affects how people reason in a given context, we articulate a simple "cognitive…

This article examines the mindset and process of undergraduate music majors conducting research in their discipline. While working with students in a writing-intensive music history class, the authors conducted several surveys, focus groups, and task-based assessments. Results indicated that most were overconfident in their research abilities,…

The ability to solve physics problems that require multiple concepts from across the physics curriculum--"synthesis" problems--is often a goal of physics instruction. Three experiments were designed to evaluate the effectiveness of two instructional methods employing worked examples on student performance with synthesis problems; these…

Requiring teachers to complete a performance-based assessment in the form of a teacher performance assessment is becoming a common way for initial teacher licensure or advancing a license. While some traditionally- and alternatively-licensed teachers from all content areas may have to complete some type of performance-based assessment for initial…
