Study on Concealment of the Subjects in Telling Stories on TAT Pictures

In studying the reliability and the validity of unstructured or projective tests, much attention has been recently paid to the question of faking, falsification and concealment. Faking and falsification may influence the result or minimize the reliability of testing, while concealment in responses not only influences the reliability and validity of testing, but this function itself is also one of the dimensions of personality. Since 1949, in the book 'Adolescent Fantasy' (an investigation of the picture method of personality study) by Percival M. Symonds, concealment has been one of the thirty-three themes in storymaking protocol analysis. On the case study of 'John Doe' in the book of Thematic Test Analysis by Edwin S. Shneidman, the theme of concealment emerged though not frequently.
