Responds to the comments by H. N. Garb (2007) and A. M. Ruscio (2007) on the current authors' original article "Plate tectonics in the classification of personality disorder: Shifting to a dimensional model" (2007). Unable to respond to all of Garb's and Ruscio's concerns given space limitations, the current authors attempt to respond to key…

In semantic categorization, masked primes that are category-congruent with the target (e.g., "Planets: mars-VENUS") facilitate responses relative to category-incongruent primes (e.g., "tree-VENUS"). The present study investigated why this category congruence effect is more consistently found with narrow categories (e.g., "Numbers larger/smaller…

This article concerns the real-world importance of leadership for the success or failure of organizations and social institutions. The authors propose conceptualizing leadership and evaluating leaders in terms of the performance of the team or organization for which they are responsible. The authors next offer a taxonomy of the dependent variables…

This empirical study evaluates the document category prediction effectiveness of Naive Bayes (NB) and K-Nearest Neighbor (KNN) classifier treatments built from different feature selection and machine learning settings and trained and tested against textual corpora of 2300 Gang-Of-Four (GOF) design pattern documents. Analysis of the experiment's…

Data mining provides both systematic and systemic ways to detect patterns of student engagement among students at hundreds of institutions. Using traditional statistical techniques alone, the task would be significantly difficult--if not impossible--considering the size and complexity in both data and analytical approaches necessary for this…

The resource typologies proposed in the new standard, "Resource Description and Access" (RDA), are evaluated in the context of a particular university library catalogue through two card-sort exercises. Although it was found that end-users recognised the content and carrier aspects of the resource types as listed in RDA, they did not…

The objective was to identify the predictors of length of stay--the impact of age, comorbidity, and stroke subtype--on the outcome of geriatric stroke patients. One hundred and seventy stroke patients (129 first-ever ischemic, 25 hemorrhagic, and 16 ischemic second strokes) were included in the study. The Oxfordshire Community Stroke Project…

If one turns to the U.S. government for answers to a daunting question: "Just who is a Hispanic?", he/she discovers that it has two different approaches to this definitional question. Both are products of a 1976 act of Congress and the administrative regulations that flow from it. One approach defines a Hispanic or Latino as a member of an ethnic…

Psychological assessment research concerns how to describe psychological dysfunction in ways that are both valid and useful. Recent advances in assessment research hold the promise of facilitating significant improvements in description and diagnosis. One such contribution is in the classification of personality disorder symptomatology. The…

A variety of studies have demonstrated that organizing stimuli into categories can affect the way the stimuli are perceived. We explore the influence of categories on perception through one such phenomenon, the perceptual magnet effect, in which discriminability between vowels is reduced near prototypical vowel sounds. We present a Bayesian model…

The authors examined how the structural attributes of tonality and meter influence musical pitch-time relations. Listeners heard a musical context followed by probe events that varied in pitch class and temporal position. Tonal and metric hierarchies contributed additively to the goodness-of-fit of probes, with pitch class exerting a stronger…

Category learning can be achieved by identifying common features among category members, distinctive features among non-members, or both. These processes are psychologically and computationally distinct, and may have implications for the acquisition of categories at different hierarchical levels. The present study examines an account of children's…

This study investigated the dimensionality and typology of perfectionism based on the Frost Multidimensional Perfectionism Scale with a sample of 380 Chinese gifted students in Hong Kong. Confirmatory factor analyses supported a five-dimensional model that includes constructs of personal standards, parental expectations, parental criticism,…

The "International Classification of Functioning, Disability and Health--ICF" (ICF-CY) conceptual framework offers a new paradigm and taxonomy of human functioning disability, which can be used to guide holistic and interdisciplinary approaches to assessment and intervention. In settings serving children, youth, or adults with disabilities, the…

Objective: To address the issue of response time (RT) profiles in hyperactive-impulsive (ADHD-HI), inattentive (ADHD-IA), and combined (ADHD-C) subtypes of ADHD. We hypothesized that children with ADHD-HI should respond more rapidly than children without ADHD and children with ADHD-IA and ADHD-C should respond more slowly than children without…
