The present study examined the relationship between anxiety, attitude toward daily communication, and stuttering symptomatology in adolescent stuttering. Adolescents who stuttered (n = 19) showed significantly higher levels of trait, state and social anxiety than fluent speaking controls (n = 18). Trait and state anxiety was significantly…

Diversity was and remains a central feature of charter schools, but some question if this is possible in an environment of standards, assessment, and accountability. Using a newly created charter school typology, this article examines charter diversity, measured by new school creation, from 1994 to 2002. Results indicate the charter landscape grew…

This study extended validity evidence for measures of coaching efficacy derived from the Coaching Efficacy Scale (CES) by testing the rating scale categorizations suggested in previous research. Previous research provided evidence for the effectiveness of a four-category (4-CAT) structure for high school and collegiate sports coaches; it also…

Basic-level picture naming is hampered by the presence of a semantically related context word (compared to an unrelated word), whereas picture categorization is facilitated by a semantically related context word. This reversal of the semantic context effect has been explained by assuming that in categorization tasks, basic-level distractor words…

Do young children who seek the conceptual kind of an artifact weigh the plausibility that a current function constitutes the function intended by the object designer? Three- and four-year-olds were encouraged to question adults about novel artifacts. After inquiring about what an object was, some children were shown a function that plausibly…

This article recalls the earliest attempts to compile international educational statistics going back into the 19th century and retraces the steps that led up to the formulation and adoption of the International Standard Classification of Education in both its original and revised versions. It is in large part the story of how international…

Perceptual grouping is a pre-attentive process which serves to group local elements into global wholes, based on shared properties. One effect of perceptual grouping is to distort the ability to estimate the distance between two elements. In this study, biases in distance estimates, caused by four types of perceptual grouping, were measured across…

The spacing effect describes the robust phenomenon whereby memory is enhanced when learning events are distributed, instead of being presented in succession. We investigated the effect of spacing on children's memory and category induction. Three-year-old children were presented with two tasks, a memory task and a category induction task. In the…

Different intuitive theories constrain and guide inferences in different contexts. Formalizing simple intuitive theories as probabilistic processes operating over structured representations, we present a new computational model of category-based induction about causally transmitted properties. A first experiment demonstrates undergraduates'…

M. P. Johnson's (1995) proposal that there are two qualitatively distinct types of intimate partner violence--intimate terrorism and situational couple violence--has been an influential explanation for disparate findings on sex symmetry in domestic violence. This study examines whether this typology increases our ability to explain variations in…

With the flourishing development of e-Learning, more and more SCORM-compliant teaching materials are developed by institutes and individuals in different sites. In addition, the e-Learning grid is emerging as an infrastructure to enhance traditional e-Learning systems. Therefore, information retrieval schemes supporting SCORM-compliant documents…

Some accounts imply that basic-level emotion categories are acquired early and quickly, whereas others imply that they are acquired later and more gradually. Our study examined this question for fear, happiness, sadness, and anger in the context of children's categorization of emotional facial expressions. Children (N=168, 2-5 years) first labeled…

A call for a bridge between research and practice is nothing new, yet it seems to be an impossible task to accomplish. Despite the dedicated efforts made by numerous researchers in the past, the world is still largely separate between researchers and teachers. One piece of evidence is that research studies seem to have only a little impact on…

Reading is the most valuable skill children must master early in schooling. Unfortunately, many students struggle to read and may be identified as having a Reading Disability (RD). In this dissertation, I explored the usefulness of the Response-to-Intervention (RtI) framework for identifying children with RD by examining the use of 1st and 2nd…

The current main world university rankings broadly group the leading research universities of nations. Australia's Go8 universities are generally within the top 250 ranked universities, with several institutions in the top 50-100 on some measures. This recognition is commendable, however imperfect the individual rankings may be. Use is made of…
