The present study evaluated the criterion validity of the aggregated tasks of basic cognitive processes (TBCP). In age groups from 6 to 19 of the Woodcock-Johnson III Cognitive Abilities and Achievement Tests normative sample, the aggregated TBCP, i.e., the processing speed and working memory clusters, correlate with measures of scholastic…

This study examined the predictive validity of the Hare Psychopathy Checklist: Youth Version (PCL:YV; A. E. Forth, D. S. Kosson, & R. D. Hare, 2003) from adolescence to early adulthood. The authors coded the PCL:YV using file information and collected criminal record information over a 10-year follow-up period on 157 boys, ages 12 through 18,…

The authors conducted 4 studies investigating the reliability and validity of the Eating Disorder Diagnostic Scale (HDDS; E. Stice, C. F. Telch, & S. L. Rizvi, 2000), a brief self-report measure for diagnosing anorexia nervosa, bulimia nervosa, and binge eating disorder. Study 1 found that the HDDS showed criterion validity with interview-based…

Forty-three children participated in a longitudinal study of mastery motivation. Children's levels of mastery motivation (persistence) and cognitive functioning were measured at ages 2 and 8. In addition, academic achievement was measured at age 8. Task persistence was stable across time for girls only, but maternal reports of mastery motivation…

Scholastic Aptitude Test (SAT) and American College Program (ACT) scores are the main determinants of college entrance in the USA. It is widely assumed that these tests are predictive of success both during college and in later life, but such views are incorrect. Another widely-held view, held by many educators, is that the SAT and ACT are…

The authors investigated trends over a 13-year period in the predictive validity of assessment center data for objective career advancement for a sample of 456 academic graduates. Using year of entry and tenure as controls, findings from research into managerial effectiveness and development were confirmed with respect to the importance of…

This study provides empirical evidence to support the validity of using a content-specific reading test for college placement decisions. A content-specific reading test presents passages exclusively from the subject area for which the placement decision is intended. Forty-nine students in a human anatomy class were administered a content-specific…

The present study investigated the differential predictive validity of the Initial Skills Analysis. In the fall, these reading screening tests were administered to students in Grades K to 3. In the spring, a series of reading outcomes tests were administered to these same students, and teachers provided judgments of the students' reading skills.…

This article reports five studies in which a scale for assessing teachers' beliefs about classroom use of critical-thinking (CT) activities was developed and its scores evaluated for reliability and validity. The Critical Thinking Belief Appraisal (CTBA) is based on a four-factor "advantage effect" model: the theoretical premise that teachers'…

This study was designed to establish and validate a multidimensional empirically based typology of clinically referred adolescent substance abusers. A total of 141 adolescent substance abusers, most of whom were male, African-American, and juvenile justice involved, comprised the study sample. Youth and their parents completed comprehensive…

This research explored the absolute accuracy of judgments of learning (JOLs), wherein absolute accuracy pertains to how well the magnitude of the participant's predictions of recall correspond to his or her subsequent recall. The Anchoring Hypothesis proposes that the magnitude of JOLs does not change systematically with item difficulty; analogous…

The ability of the "Millon Adolescent Clinical Inventory"("MACI"; Millon, 1993) to identify serious adolescent, male sexual-offenders and to predict their recidivism following treatment was examined. "MACI" scores were evaluated for 381 adolescent, male sexual-offenders adjudicated delinquent for felony crimes and given maximum sentences, and, on…

We present an expository account of the development of the theory of binary quadratic forms. Beginning with the formulation and proof of the Two-Square Theorem, we show how the study of forms of the type x[squared] + ny[squared] led to the discovery of the Quadratic Reciprocity Law, and how this theorem, along with the concept of reduction relates…

There is growing evidence that current classification methods are not consistent with current empirical knowledge of childhood psychopathology and the optimal way to classify school-age children remains controversial. The current study investigated three classification methods (categorical, dimensional, person-oriented) for use in predicting…

We develop a simple model of teacher behavior that offers a solution to the ''class size puzzle'' and is useful for analyzing the potential effects of the No Child Left Behind Act. When teachers must allocate limited classroom time between multiple instructional methods, rational teachers may respond to reductions in class size by reallocating…
