Compared six effect size (ES) measures commonly used by gerontological researchers as these measures relate to one another in both the analysis of variance and multiple regression models. Also discusses three other issues involving ES measures: the ES of a contrast; orthogonal and nonorthogonal designs; and partial ESs. (Author/JAC)

The Wechsler Preschool and Primary Scale of Intelligence (WPPSI) has recently undergone a major revision and restandardization to update its 20-year-old norms, extend the age range down to age 3 and up to age 7 years, update and revise its test items, and increase its appeal to young children. This paper presents the results of a concurrent…

One hundred and twenty-eight subjects responded to one of four differently labeled five-point Likert-type response scales. Although no significant differences in test means and in reliability estimates were found among response scales, the scales did differ on measures of variability. (Author/LMO)

Using a modified Posner "encoding function" methodology, group differences in semantic encoding speed were assessed under conditions in which subjects encoded pictures of common objects to determine physical identity matches, name identity matches, and superordinate identity matches. Results of primary interest revealed group differences in basic…

The hypothesis that first-year medical residents' evaluate their performance in a more differentiated manner than their supervisors was evaluated. An evaluation form was developed to obtain ratings of performance in 13 specific areas. Results showed that residents were more discriminating than supervisors in evaluating residents performance.

Describes study that investigated the effects of computerized test administration on undergraduates' responses to the Minnesota Multiphasic Personality Inventory (MMPI), and discusses methodological considerations important in evaluating the sensitivity of personality inventories in different administration formats. Results analyze the effects of…

This study compares the McCarthy Scales of Children's Abilities (MSCA) and the Kaufman Assessment Battery for Children (K-ABC) profiles of successful and unsuccessful preschoolers with learning disabilities. Subjects, 40 preschool students, were tested at the beginning and at the end of the preschool year and were placed into repeating or…

A statistical method has been developed for nested incomplete samples in a longitudinal study in which part of the sample has dropped out in such a way that the data have a nested pattern. A procedure which performed well in a Monte Carlo experiment was extended to a two-factor incomplete design with repeated measures on one factor. Methods…

A cross-racial comparison of the Wechsler Adult Intelligence Scale (WAIS) was made with the revised version, the WAIS-R. Three groups of Anglo, Black, and Mexican-American male college students were administered both versions of the WAIS on the same day. Significant differences were found among the racial groups.

The Stanford-Binet: Fourth Edition and Kaufman Assessment Battery for Children were administered in counterbalanced order followed by the Cognitive Domain of the Battelle Developmental Inventory to a sample of 30 nonhandicapped, preschool children (13 males and 17 females). Correlations (corrected for restriction in range) among the three…

The comparative effects of various sequences of test items were examined for over 900 graduate students enrolled in an educational research course at The University of Alabama, Tuscaloosa. experiment, which was conducted a total of four times using four separate tests, presented three different arrangements of 50 multiple-choice items: (1)…

Grade level norms were developed, based on a sample of 678 elementary school students, for various error scores of the Benton Visual Retention Test. Norms were also developed for 201 normal children, 58 minimal brain dysfunction children, and 101 educable mentally retarded children. In both the copying mode and the memory mode, most errors were…

Groups of retarded and nonretarded children were investigated as they learned three rules underlying problems adapted from the Raven Progressive Matrices Test: rotation, imposition, and subtraction. Results were seen as consistent with theories that emphasize transfer flexibility as one potential source of individual and comparative differences in…

A refined and extended analysis of variance (ANOVA) approach was used to investigate the pattern of relationships among arithmetic ability; reading ability; and general ability as assessed by teacher ratings and standardized tests, over a three-year period, with 54 educable mentally retarded children, initially 12 years old.

The Myers-Briggs Type Indicator (MBTI) Extraversion-Introversion scale was compared with the Minnesota Multiphasic Personality Inventory (MMPI) 0 scale (Social Introversion) for 18 male and 66 female adult students in introductory courses in psychology, aged 17 to 83 years. A status survey design was used with a priori and post hoc groupings.…
