Two tests for the jackknife autocorrelation estimator r(Q2) are evaluated. It is shown that a test based on the conventional approach for estimating the standard error of a jackknife estimator leads to unacceptable Type I error. An alternative approach is proposed that leads to a more satisfactory test when n>20. (Author/SLD)

Findings related to internal consistency, temporal stability, and principal components structures suggest that the Anger Expression Scale (C. Spielberger and others, 1985) and the Pediatric Anger Expression Scale (G. Jacobs and others, 1989), studied with a sample of 415 youth with a mean age of 14.7 years are acceptably reliable. (SLD)

The present study was conducted to test predictions derived from the hypothesis that depression may serve the purpose of adaptively facilitating disengagement from obsolete cognitive plans. Groups of students with either low or high depression scores were contrasted using a procedure that featured an initial learning phase, within which…

This article describes the findings of studies conducted on a large-scale, classroom-based performance assessment of literacy for the early grades designed to provide information that is useful for reporting, as well as teaching. Technical studies found the assessment to be a promising instrument that is reliable and valid. Follow-up studies of…

The current study examines the views of experts in the science of mental abilities about the primacy and uniqueness of "g" and the social implications of ability testing, and compares their responses to the views of a group of non-expert psychologists. Results indicate expert consensus that "g" is an important, non-trivial determinant (or at least…

Within the context of standards-based educational systems, states are using large scale reading assessments to help ensure that all children have the opportunity to learn essential knowledge and skills. The challenge for developers of accessible reading assessments is to develop assessments that measure only those student characteristics that are…

Homogeneity of variance (HOV) is a major assumption underlying the validity of many parametric tests. More importantly, it serves as the null hypothesis in substantive studies that focus on cross- or within-group dispersion. Despite a widely acknowledged need for testing HOV, very few textbooks give adequate coverage on the topic, and many HOV…

Two achievement tests--the Peabody Individualized Achievement Test (PIAT) and the Comprehensive Test of Basic Skills (CTBS)--were administered to emotionally disturbed and behavior-disordered children in an inpatient psychiatric setting. The results of this study suggest that these two measures might be used interchangeably in every area but…

Deals with the use of the "lie detector" or "polygraphic test" as a method of detecting deception in industries and law enforcement agencies. Explains what the polygraph is and how it operates. Presents a series of specific arguments for and against the validity of the instrument. Research appears to be inconclusive. (Author/ABB)

This study attempted to gain insight into what teacher candidates think about teacher-competency testing and how test results should be used. A majority of students were negative toward testing, and the weight test scores could be given in hiring and evaluation of teachers. Implications and recommendations are discussed. (MT)

The study examined the stability of WISC-R (Wechsler Intelligence Scale for Children-Revised) Verbal-Performance (V-P) differences at the triannual reevaluation of 71 learning disabled students from Hawaii. Results revealed a slight increase of three points in the V-P differences, with a correlation of .55 between the Time 1 and Time 2 V-P…

Abbreviated CID W-22 lists were administered to normal and hearing-impaired adults to test the hypothesis that fewer judiciously chosen items can be used to test word recognition without compromising test accuracy. Results show that fewer items can be used if the words are sufficiently difficult and strict passing criteria are employed. (Author/CL)

Results of gifted fourth-sixth graders on the Structure of the Intellect Learning Abilities Test are analyzed in terms of the test's measure of five operations (evaluation, convergent production, divergent production, memory, and cognition). (CL)

Eighty-four hearing-impaired children (6-16 years old) were administered the Wechsler Intelligence Scales for Children-Revised Performance Scales and Raven's Coloured or Standard Progressive Matrices. Correlations coefficients between the two instruments were significant. It appears matrices could be used as a guide to level of intellectual…

An investigation of the use of an experimental test battery in discriminating between normally achieving and learning disabled secondary students (N=75) revealed that three items from the four tests effectively discriminated between the two groups of students. These were the TOAL Reading Quotient, the Woodcock-Johnson Proofing and the Raven's…
