This study is a concurrent validation of Level II of the Wide Range Achievement Test-Revised (WRAT-R) using the Wechsler Adult Intelligence Scale (WAIS) Verbal, Performance, and Full Scale IQ scores as criterion measures. Forty-five subjects were administered the WAIS-R and WRAT-R and their scores correlated. (Author/LMO)

The hypothesis testing abilities of 15 language impaired and 15 normally developing children matched for mental age were investigated using discrimination-learning tasks. Findings indicated the impaired children performed poorer than non-impaired children especially on the nonexplicit problems suggesting the deficits may be related to difficulties…

Introductory psychology students were graded on four tests using multiple-choice format with explicit option (E-option) to explain their answers. Students preferred E-option format over regular multiple-choice, short answer, essay, true/false, and fill-in-the-blank formats. Use of E-option averaged less than one explanation per test over four…

The logic and procedures underlying a disturbance term regression test of logical consistency for structural models are reviewed for recursive and nonrecursive designs. It is shown that in a simple three-variable, complete mediational case the test procedure is mathematically equivalent to a part correlation. (Author/LMO)

A general procedure is provided for comparing correlation coefficients between optimal linear composites. It allows computationally efficient significance tests on independent or dependent multiple correlations, partial correlations, and canonical correlations, with or without the assumption of multivariate normality. Evidence from Monte Carlo…

The author describes the use of the revised Detroit Tests of Learning Aptitude and the Woodcock-Johnson Psycho-Educational Battery for students with learning disabilities. He cautions about making a diagnosis on the basis of only one test. (CL)

The Symbolic Play Test was given to 31 socially impaired and 29 sociable elementary grade children retarded in language comprehension, of similar intelligence (profoundly retarded to normal). Play test age and spontaneous pretend play were similar in sociable Ss but, in the socially impaired, spontaneous pretend play was lower than play test age…

The content and process of individual psychological testing can facilitate family therapy goals. Relevant research on the Barnum effect is reviewed, and an illustrative case is presented. (Author)

Microanalysis of test-related behaviors of six examiners and 15 preschool speech- and language-handicapped children revealed that the children spoke significantly more often with greater complexity when tested by familiar examiners. Differences between familiar and unfamiliar examiners included use of silence, eye contact, and language style and…

Fifteen learning disabled students (six to nine years old) scored significantly higher on the PIAT spelling subtest than on a dictated spelling test using identical words. Either approach, however, (selection or supply) ranked subjects similarly. (Author/CL)

Discusses an interactive testing and tutoring system for use within any discipline. The system (which consists of four interconnected computer programs) was developed at Iowa State University to test and tutor students in courses with large student to faculty ratios. (JN)

When the experimental units are measured twice, and the response variable is dichotomous, the equality of the two proportions is usally assessed by Mc Nemar's (1947) test. In this paper, Bayesian methods are presented for testing hypotheses regarding the two success probabilities in light of complete and incomplete data. (Author/BW)

Compared several clinical-behavioral and self-report measures of psychopathy in a sample of 274 male prison inmates. Found much stronger agreement among the clinical-behavioral measures (ratings, checklist, and DSM-III) than among the self-report measures. Agreement between these two measurement domains was, with few exceptions, rather poor. (BH)

Argues that, although expert systems--which are supposed to give users all the advantages of consulting with human experts--can be useful for medical diagnosis, where tests tend to be reliable, they can be hazardous in such areas as psychological testing, where test reliability is difficult to measure. (MBR)

A learning disability index (LDI) based on a principal components analysis of the Weschler Intelligence Scale for Children-Revised normative data has been developed to depict verbal or nonverbal deficits on that test. Ss (N=1550) referred for educational difficulties returned mean scores on the LDI that were reliably different from expected scores…
