This is an excerpt from the paper...
There are a variety of testing procedures used for the assessment of psychological traits and behavior, or for measuring some specialized aspect of ability. According to Groth-Marnat (2003), projective tests attempt to measure personality based on the theory that individuals tend to project their own unconscious attitudes into ambiguous situations. While the best known of the projective tests is the Rorschach Inkblot Test, The Thematic Apperception Test (where apperception refers to the assimilation of perceptual stimuli and conceptual memory information into a consistent representation) is one also one of the most frequently used of the projective tests (Cramer, 1996). The purpose of this paper is to provide a comprehensive description and discussion of the Thematic Apperception Test. To this end, the paper provides a brief description and general overview of the test, followed by a discussion of its construction and psychometric properties (e.g., validity, test-retest reliability, internal consistency, etc.), test administration procedures and its scoring and interpretation methods. Regarding the general purpose and features of the TAT, Aronow, Weiss and Reznikoff (2001) report that it was originally developed by Christiana D. Morgan and Henry A. Murray for the purpose of revealing underlying psychodynamic features of test-takers' personality such as their internal conflicts, dominant drives, interests, motives, and so forth. Until the 1970s, it was most

ere, there is some doubt regarding the psychometric soundness of the instrument. In this regard, Spangler (1992) conducted a meta-analysis of TAT-based assessments of achievement motivation. According to the authors, their analysis indicated that these measures exhibited convergent validity with two classes of real-world achievement measures. But the absolute magnitude of this validity was relatively low, with average correlations falling between .19 and .22. in magnitude. Moreover, McCrae and Costa (1984) reported that even when studies conducted on TAT-based measures have relatively high correlations, they have proven difficult to replicate.
Also, there is relatively little evidence that TAT-based achievement measures show incremental validity beyond the measurement of intelligence; however, Woike (1995) does not that incremental validity of measures of affiliation (and of power) do show more strength. Still, Woike reports that further investigation is necessary before even moderate confidence can be placed in these findings.
On the other hand, Lillenfield, Wood and Garb (2001) do acknowledge that there is some support for the construct validity of TAT-based measures of achievement, power and affiliation, and conclude that t
