This project had as its specific objective the development and field testing of a procedure for identifying the structure of technical concepts possessed by a group of selected quality control specialists. The associative theory of verbal behavior served as the rationale by which conceptual structures depicted by graphical maps of technical concepts possessed by the specialist were developed and validated. A sample of statistical quality control key stimulus words representing technical concepts was selected and randomly arranged to elicit continued free association responses from thirteen quality control specialists. Response data analysis procedures and analytical models were developed for structuring statistical quality control conceptual structures and depicting those structures in graphical concept maps. Computer programs necessary to facilitate data analysis techniques were developed and used. The procedural model, data gathering instrument format, and computer programs developed and utilized during the project are considered appropriate for use in developing associative conceptual structures (maps) for other technical and engineering related subject areas. The appendix includes an example of the response booklet which specialists were asked to complete, response summary sheets, final list of pooled response words, ratio of coefficients (RC) computer program, RC computational example, and a factor analysis computer program.
