Tested the factor structure of the McCarthy Scales of Children's Abilities in preschool children (N=141). Found existence of Verbal factor and other Perceptual-Performance factor was confirmed and the Quantitative and Memory factors appear undifferentiated. Found subtests which make up the Motor scale do not constitute a single factor. (Author/ABL)

Administered McCarthy Scales of Children's Abilities to preschool children of normal intelligence with (n=25) and without (n=25) speech/language disorders. Speech/language disorders group had significantly lower scores on all scales except Motor; showed difficulty in short-term auditory memory skills but not in visual memory skills; and had…

Describes the development and preliminary analysis of the Stanford Education Program for Gifted Youth Mathematical Aptitude Test (SEMAT), a math test targeted for high-mathematical-ability elementary school students. Reports that SEMAT discriminated students in the few top percentiles. Contains 14 references. (Author/ASK)

A larger canonical correlation of Self-Directed Search scores with those from the Ball Aptitude Battery for 198 high school students was found compared to results from a 1977 study being replicated. Only modest overlap between the Self Directed Search and the Ball Aptitude Battery was found. (SK)

Medicine is a profession with a long history of research and high standards of methodological rigour and evidence-based decision making. These standards are being transferred into medical education. Universities are starting to collect high-quality data on their admissions systems. This has not been a short-term proposition. Medical courses are…

The newly revamped Scholastic Aptitude Test (SAT) was administered for the first time in March 2005. Administrators, faculty, and staff in colleges and universities throughout the country were asking the same questions as students: "What was this new score of 2400 and what would it mean for them in terms of admissions, scholarships, and…

Factor analyses of the McCarthy Scales were performed on separate groups of black and white children to assess the comparability of the underlying structures and to evaluate the construct validity of the MSCA for each racial group. There was evidence of the instrument's construct validity for each racial group. (Author)

The purpose of this study was to assess the effects of correlated dimensions and differential ability on one dimension on parameter estimation when using a two-dimensional item response theory model. Multidimensional analysis of simulated two-dimensional item response data fitting the M2PL model of M. D. Reckase (1985, 1986) was conducted using…

A study of children enrolled in a year-round preschool program for the "culturally disadvantaged" in Tampa, Florida revealed that children with defective vision performed more poorly on both the Peabody Picture Vocabulary Test and Metropolitan Readiness Test. (Author/JM)

The study involving 614 hearing impaired students investigated the adequacy of time limits currently followed in the administration of two subtests of the Differential Aptitude Test battery when used with young deaf students. Thirty-six students who did not complete the Space Relations portion of the battery under the timed condition, and 11 who…

As test standards and research literature in general indicate, definitions of test bias and item bias vary considerably, as do the results of existing methods of identifying biased items. The situation is further complicated by issues of content, context, construct, and criterion. In achievement tests, for example, content validity may impose…

EIGHT INSTRUCTIONAL TESTS SPANNED THE CURRICULUM OF ONE YEAR OF BIOLOGY STUDY. THE FIRST CONCERNED THE NATURE OF SCIENCE INCLUDED 4 AREAS OF EMPHASIS--THE NATURE AND FUNCTION OF HYPOTHESIS, THE IDEA OF CONTROLS IN EXPERIMENTS, INTERPRETATION OF GRAPHED DATA, AND THE NATURE OF DATA. THE SECOND TEST WAS DESIGNED TO SHOW AN UNDERSTANDING OF…

DATA COLLECTED FROM 15 YEARS OF PSYCHOLOGICAL TESTING UNDER THE APTITUDES RESEARCH PROJECT IN THE DEPARTMENT OF PSYCHOLOGY, UNIVERSITY OF SOUTHERN CALIFORNIA, WERE MICROFILMED OR KEYPUNCHED AND MADE AVAILABLE TO EDUCATORS, PSYCHOLOGISTS, AND GRADUATE STUDENT RESEARCHERS. EACH TEST HAD BEEN ADMINISTERED TO ABOUT 600 EXAMINEES. STUDENT HAND-WRITTEN…
