Document Summary
Controversial, because reliability and validity are in dispute. Rorschach inkblot test - consists of ten symmetrical inkblots, five in black-and-white and five containing colour. Examiners ask respondents to look at each inkblot and say what it resembles. This supposedly tells you about personality traits of the respondent. Rorschach evaluated scientifically - unknown test-retest and problematic interrupter reliability scores. You may have different responses to the same ink blots. Little evidence that it detects features of mental disorders. Thematicapperceptiontest(tat) - requires subject to construct a story based on pictures. Uses this to open up dialogue with their patients if they are not talking. Little evidence for adequate reliability or validity for most applications. Other projective tests - human figure drawings require you to draw a person(s) in any way you wish. Graphology is an analysis of handwriting is another projective test. Our handwriting does not correlate with our personality. It is just our personalized way of writing.
