The incremental validity and clinical utility of the recently developed Minnesota Multiphasic Personality Inventory-2 (MMPI-2) Infrequency Posttraumatic Stress Disorder Scale (Fptsd) was examined in relation to the family of MMPI-2 F scales in distinguishing feigned post-traumatic stress disorder (PTSD) from disability claimants with PTSD.…

Previous investigations of the variable marking of past time by the L2 learner have given rise to a number of hypotheses which predict the patterns of acquisition and use of past time markers in interlanguage (IL). However, given the complicity between their predictions, it has been previously noted that hypotheses such as the aspect and discourse…

In multiple-cue learning (also known as probabilistic category learning) people acquire information about cue-outcome relations and combine these into predictions or judgments. Previous researchers claimed that people can achieve high levels of performance without explicit knowledge of the task structure or insight into their own judgment…

We present a set-theoretic model of the mental representation of classically quantified sentences (All P are Q, Some P are Q, Some P are not Q, and No P are Q). We take inclusion, exclusion, and their negations to be primitive concepts. We show that although these sentences are known to have a diagrammatic expression (in the form of the Gergonne…

This paper outlines a novel approach to studying children's singing that enables a more accurate and global picture to be drawn of children's actual level of singing achievement across a range of tasks. It enables predictions to be made about their potential singing development in a formal school setting. It draws on a two-year longitudinal field…

A method designed to facilitate prediction of mechanism and products by developing critical thinking skills and reducing memorization is presented. The mechanistic disc method requiring students to utilize their understanding of charge stabilization, structural organic chemistry, and the fundamental mechanisms of aliphatic substitution and…

This experiment investigated relational complexity and relational shift in judgments of auditory patterns. Pitch and duration values were used to construct two-note perceptually similar sequences (unary relations) and four-note relationally similar sequences (binary relations). It was hypothesized that 5-, 8- and 11-year-old children would perform…

The purpose of this study was to evaluate the criterion-related validity of a 3-min step test using 3 stepping cadences. Chinese children (N = 50; age = 8.92 plus or minus 1.64 years) performed three 3-min bouts of a bench stepping exercise on a 12-in.-high (30.5 cm) bench. Stepping cadences for the 3 step tests were 22, 26, and 30 steps per…

Objective: To examine the longitudinal association between individual subthreshold symptoms and onset of major depressive disorder (MDD) in adolescence. Method: Data for analysis come from the Oregon Adolescent Depression Project, a prospective epidemiological study of psychological disorders among adolescents, ages 14 to 18 years, from the…

Background: Findings from family and twin-based studies of Attention Deficit/Hyperactivity Disorder (ADHD) have indicated that inattentive and combined subtypes cluster together among sibling pairs who both express ADHD symptoms. The current report examines the familial clustering of ADHD subtypes, defined according to latent class and DSM-IV…

Categorical accessibility is a cognitive factor that limits the extent of creative conceptual expansion. In the present study, we sought to establish the categorical accessibility norms in five conceptual domains among American and Hong Kong Chinese university students. In addition, we predicted that the tendency to access normatively inaccessible…

A neglected part of the history of teaching sociology is the history of teaching high school sociology. The American Sociological Association's centennial in 2005 affords sociologists an opportunity to reflect on the teaching of sociology--anywhere and everywhere that it happens. In the spirit of contributing to the history of teaching sociology…

This study presents a theory of critical components that affect the effectiveness of computer-based instruction (CBI) for adults. The theory was developed to provide a framework for research to explain or predict effective learning by adults using a desktop computer. The five conclusions drawn from this theory are as follows: (a) the…

The relative contribution is examined of epistemological beliefs and implicit theories of intelligence to students' adoption of mastery, performance-approach and performance-avoidance goals in two different academic contexts, business administration and teacher education, in the short as well as the long term. The results showed that…

This study examined the relationships of vocational interests and self-efficacy expectations, or confidence, to personality, as measured by the Personal Styles scales of the Strong Interest Inventory. The study also examined the extent to which confidence and personality measures contributed incrementally to the prediction of occupational group…
