This simulation study compared maximum likelihood (ML) estimation with weighted least squares means and variance adjusted (WLSMV) estimation. The study was based on confirmatory factor analyses with 1, 2, 4, and 8 factors, based on 250, 500, 750, and 1,000 cases, and on 5, 10, 20, and 40 variables with 2, 3, 4, 5, and 6 categories. There was no…

Preschoolers experience the world in its purest form, to the delight of those who are not too busy to observe. Preschool is an opportune time to begin to apply Bloom's Taxonomy, given young children's openness and willingness to see the world in so many ways. This article provides playful and engaging activities for preschoolers which help enhance…

The explanations of thirty primary pupils for changes in matter were recorded through individual, semi-structured interviews. The analysis of data pointed to the construction of a system for classifying pupils' explanations of changes in matter. A parallel analysis of data focused on the identification and interpretation of associations between…

Practitioner involvement in evaluation, research, development, and other forms of disciplined inquiry that are small scale, local, grounded, and carried out by professionals who directly deliver those services is embraced across a wide range of professions as essential to good professional practice. However, little is known about the character,…

The distinction between individuals (e.g., Rin-Tin-Tin) and categories (e.g., dogs) is fundamental in human thought. Two studies examined factors that influence when 2- to 3-year-old children and adults focus on individuals versus categories. Mother-child dyads were presented with pictures and toys (e.g., a picture of a boat or a toy boat).…

The present study determined specificity and sensitivity to malingered neurocognitive dysfunction (MND) in traumatic brain injury (TBI) for several Wechsler Adult Intelligence Scale (WAIS) Digit Span scores. TBI patients (n = 344) were categorized into one of five groups: no incentive, incentive only, suspect, probable MND, and definite MND.…

The purpose of this study was to determine whether multiple-tact training and receptive-discrimination training could be used to teach thematically related vocal intraverbals to typically developing preschool children. Multiple-tact training involved teaching a child to name both the item and the category to which the item belonged.…

The present study tests a model of category effects upon stimulus estimation in children. Prior work with adults suggests that people inductively generalize distributional information about a category of stimuli and use this information to adjust their estimates of individual stimuli in a way that maximizes average accuracy in estimation (see…

The "Weather Prediction" task is a widely used task for investigating probabilistic category learning, in which various cues are probabilistically (but not perfectly) predictive of class membership. This means that a given combination of cues sometimes belongs to one class and sometimes to another. Prior studies showed that subjects can improve…

People live in an era of partnering--of joining institutional forces to accomplish complex societal changes. Whether it is the local YMCA that works with a school to serve children during the afterschool hours, a university connecting with its surrounding community, or a city government convening funders and businesses, they are moving into…

Purpose: The purpose of this paper is to review the literature which focuses on four major higher education decision problems. These are: resource allocation; performance measurement; budgeting; and scheduling. Design/methodology/approach: Related articles appearing in the international journals from 1996 to 2005 are gathered and analyzed so that…

This article explores use of several terms that signify Islam, and provides guidelines to clarify their use in internal and external discourses. Building on this foundation, the article delineates a typology of Islamic education and their associated institutions. This enhances understanding of important conceptual differences that hinge upon…

We directly compared chimpanzee infants and human infants for categorical representations of three global-like categories (mammals, furniture and vehicles), using the familiarization-novelty preference technique. Neither species received any training during the experiments. We used the time that participants spent looking at the stimulus object…

After learning to categorize a set of alien-like stimuli in the context of a story, a group of 5-year-old children and adults judged pairs of stimuli from different categories to be less similar than did groups not learning the category distinction. In a same-different task, the learning group made more errors on pairs of non-identical stimuli…

A self-paced reading experiment investigated processing of sentences containing a noun-phrase that could temporarily be mistaken as the direct-object argument of a verb in a subordinate clause but actually constituted the syntactic subject of the main clause (often referred to as an "early" vs. "late closure" ambiguity). Subcategorization…
