Thematic Apperception Test (TAT): A subjective personality test where ambiguous pictures are shown to an individual who is asked to clarify their meaning. Not to be confused with the Thematic Imperception Test (TIT), where clear pictures are shown to an individual, who proceeds to make them ambiguous. These tests are used interchangably by married couples, who conflict interminably about the meaning about such clear or ambiguous pictures such as unmade beds, dirty dishes, etc. This interchangability is also known as TIT for TAT.
