Foreign language aptitude is defined as one's potential to learn a second language. A language learner with higher aptitude is predicted to learn more, faster, and reach a higher level of proficiency. If this is the case, one way to validate the construct of aptitude and its measure is to conduct a validation study in which measures of aptitude is…

Test-retest reliability coefficients for the brief Career Ability Placement Survey and concurrent validity correlations against the Differential Aptitude Tests and the General Aptitude Test Battery are presented for samples of ninth and tenth grade students. (Author/JKS)

Three multiple-abilities batteries--the Comprehensive Ability Battery, Differential Aptitude Tests, and General Aptitude Test Battery--are briefly discussed, and results of a study involving cross-correlations of the tests in these batteries are presented. (Author/JKS)

A procedure for estimating the degree to which a subtest uniquely contributes to total test performance is presented and discussed. Uniqueness analysis may be appropriately applied to any composite measurement instrument such as a multipart test or a multitest battery to assess the unique contribution of each component to the total test. The…

Data from over 1,200 correlations reported in 38 studies concerning validity of aptitude and achievement predictors of success in high school vocational programs are summarized. Predictors investigated were (1) verbal intelligence, (2) nonverbal intelligence and abstract reasoning, (3) arithmetic reasoning, (4) spatial aptitude, (5) mechanical…

To determine whether the visuospatial n-back working memory task is a reliable and valid measure of cognitive processes believed to underlie intelligence, this study compared the reaction times and accuracy of performance of 70 participants, with performance on the Multidimensional Aptitude Battery (MAB). Testing was conducted over two sessions…

The present study suggests that although the reliability of an academic aptitude test given under formula-score condition can be increased substantially through empirical option weighting, much of the increase is due to the capitalization of the keying procedure on omitting tendencies which are reliable but not valid.

An aptitude test requiring 10-minutes' administration time was administered to high school students learning Forkner, Century 21, and Gregg shorthand for the purpose of determining test validity for different shorthand systems. Validity data were obtained from approximately 2000 students. Aptitude test reliability ranged from KR20=0.88 to 0.90.…

An investigation was conducted to determine the effects of response-category weighting and item weighting on reliability and predictive validity. Response-category weighting refers to scoring in which, for each category (including omit and "not read"), a weight is assigned that is proportional to the mean criterion score of examinees selecting…

The general intelligence factor (g) was investigated using 170 university students across three batteries of ability measures: (1) a short-term memory battery; (2) the Multidimensional Aptitude Battery; and (3) a reaction time battery. Results support the notion of g and suggest short-term memory as an essential aspect of intelligence. (SLD)

Standard and experimental forms of the Johnson O'Connor Research Foundations Analytical Reasoning test were administered to 1,496 clients of the Foundation (persons seeking information about aptitude for educational and career decisions). The objectives were to develop a new form of the test and to better understand what makes some items more…

Results of an analysis of a newly developed spelling test and several related measures are reported. Information about the reliability of a newly developed spelling test; its distribution of scores; its relationship with the standard battery of aptitude tests of the Johnson O'Connor Research Foundation; and its relationships with sex, age,…

The selection of an appropriate test battery is based on its content and applicability to the vocational trainee population. This report describes the testing of a national sample of U.S. high school students with an established version of Armed Services Vocational Aptitude Battery (ASVAB), and a new, enlarged version of the same test battery.…

A nontechnical approach to statistics is presented. The examples and illustrations have been drawn from the classroom and the needs of teachers who wish to measure and understand the progress of their pupils. The areas covered include the following topics: (1) different forms of average, middle value, dispersion of data around the average, and the…

The purpose of this technical report is to describe the Tests of General Ability and Tests of Reading of the Inter-American Series, to give a brief account of their construction, and to present related statistical data. Norms and suggestions on the use and interpretation of the tests are published separately. The Inter-American Series discussed in…
