Performance Testing with Microprocessors: Mechanization is Not Implementation

Microprocessors in the form of personal computers and home game systems are now widely available at affordable prices. Researchers are rapidly acquiring systems for the collection and analysis of data and recording of results. However, the use of these devices parallels the implementation of the early apparatus-based tests which began their development during World War II. Although increased speed in test administration was gained, the mechanization of traditional tests, at times, resulted in alteration of the behavioral factors studied, as well as difficulties with equipment reliability. Pitfalls to be avoided when considering a test for microprocessor mechanization include: (a) equipment factors, (b) quantitative issues, and (c) their interactions. This report outlines the procedures one should follow when implementing a microprocessor based performance test battery.
