Results pertaining to methodological aspects of an aptitude-treatment interaction study are presented. One treatment group in the study was given imagery instructions, the other had no imagery instructions. Each treatment group consisted of seven fifth-grade classes. Among the aptitude variables there were two versions of a paired-associates…

An objective procedure was developed and tested to determine the relative difficulty of Air Force jobs. Also investigated were (1) the measurement of task difficulty to allow comparability across specialties, (2) the quantitative appraisal of job demands based on component tasks being performed, and (3) the comparability of job difficulty to job…

A study investigating interactions between imagery instructions and aptitude variables is presented. One group consisting of seven fifth-grade classes was given imagery instructions in the reading of a short text, while another group read the text in a regular way. Three different outcomes covering different types of learning were registered. As…

The purpose of this study was to confirm or deny Carry's findings in an earlier Aptitude Treatment Interaction (ATI) study by implementing his suggestions to: (1) revise instructional treatments, (2) improve the criterion measures, (3) use four predictor tests, (4) add time to criterion measure, and (5) use a theoretical model to identify relevant…

Reviews concepts of aptitude and aptitude-treatment interaction (ATI) and summarizes lessons learned in ATI research on educational treatments to help ATI research on psychotherapeutic treatments. Research design and data analysis recommendations address aptitude distributions, multivariate aptitude complexes, detective work with scatterplots,…

The literature on medical education does not contain many studies directly concerning ATI (Aptitude-Treatment Interaction) or more broadly TTI (Trait-Treatment Interaction), in spite of the great many studies on the characteristics of medical students. Nevertheless, a project at Michigan State University was begun in which an entry profile of all…

The paper cites difficulties in aptitude-treatment interaction (ATI) research which investigates relationships between test performance and the extent of profiting from instruction. Two methods for ATI research (regression analysis and analysis of variance) are described, assumptions and potential mininterpretations are noted, and correct…

The Joreskog and Sorbom LISREL (linear structural relations) method is investigated as an alternative to regression analysis in studies of aptitude-treatment interactions (ATI), to solve problems caused by unreliability of measurements and by large sets of variables. A study reported by M.J. Behr is reanalyzed. This study investigated relations…

Subjects were pretested and then randomly assigned to a verbal treatment or a figural treatment for a programed lesson on the integers modulo 7. The expected interactions among treatment success and cognitive abilities were not observed. The authors suggest further study. (SD)

Discusses epistemological and methodological issues regarding aptitude-treatment interactions (ATI) in psychotherapy. Noting that track record of interactional research is not very encouraging, argues that ATI research should focus on heuristic goal of illuminating mechanisms and processes that make therapies differentially effective. Suggests…

Subjects were randomly assigned to a deductively structured verbal-symbolic-numeric treatment or an inductively structured verbal-spatial-numeric treatment for a unit on quadratic inequalities. Success on the deductive symbolic approach was associated with general reasoning ability; success on the inductive spatial approach was associated with…

Students were measured on eleven aptitudes from Guilford's structure-of-intellect cube, and randomly assigned to symbolic or figural instructional modes for a unit on functions. Achievement was measured and compared for students with different aptitudes. (SD)

Notes that smaller than expected main effects in psychotherapy research are often attributed to mismatches between clients and treatment. Examines issues in aptitude-treatment interaction (ATI) research in psychotherapy, including Type II and Type III errors, manipulation checks from both patient and practitioner perspectives, considerations of…

The optimal allocation of Air Force talent requires, among other considerations, the measurement of both enlistee aptitudes and job aptitude requirements. Although objective procedures are available to measure aptitudes accurately, the procedure presently employed for establishing relative aptitude requirements is both unsystematic and subject to…

An empirical study investigated whether personality characteristics have a bearing on an individual's success with particular modes of instruction, in this case, computer-assisted instruction (CAI) and the programed text (PT). The study was developed in an attempt to establish useful criteria on which to base a rationale for choosing suitable…
