Abstract: The TAT measure of motive and its coding system represent the traditional method in measuring motivation. Although they have been suspected for the metrical issues, they indeed caused the discrimination between the concepts of implicit and explicit motives. Further more, the researcher’s also established sufficient reliability and validity. However, new techniques are still continuously being developed. The emerging of MMG has inspired the measurement of implicit motives; and the test battery Work Style gives us another way to make the measurement more objective by observing behavioral performance; while the introduction of the IAT in to implicit motive measurement presents us a more effective, easier, and more accurate method, which was regarded as a milestone in measuring motivation

Key words: implicit motive, explicit motive, implicit measure, MMG, IAT
