Hi Dr. Kavita,
From your view i understand that there shall be 12 slides to be used while administering TAT (Thematic apperception test). But when i did a research on the topic I found that few psychologists has suggested to make use of around 31 slides to be offer to the subject. I request you to go through the article given below and put some light on the issue.
The Thematic Apperception Test, or TAT, is a projective measure intended to evaluate a person's patterns of thought, attitudes, observational capacity, and emotional responses to ambiguous test materials. In the case of the TAT, the ambiguous materials consist of a set of cards that portray human figures in a variety of settings and situations. The subject is asked to tell the examiner a story/ opinion about each card.
Because the TAT is an example of a projective instrument— that is, it asks the subject to project his or her habitual patterns of thought and emotional responses onto the pictures on the cards— many psychologists prefer not to call it a "test," because it implies that there are "right" and "wrong" answers to the questions. They consider the term "technique" to be a more accurate description of the TAT and other projective assessments.
The TAT is usually administered to individuals in a quiet room free from interruptions or distractions. The subject sits at the edge of a table or desk next to the examiner. The examiner shows the subject a series of story cards taken from the full set of 31 TAT cards. The usual number of cards shown to the subject is between 10 and 14, although Murray recommended the use of 20 cards, administered in two separate one-hour sessions with the subject. The original 31 cards were divided into three categories, for use with men only, with women only, or for use with subjects of either sex. Recent practice has moved away from the use of separate sets of cards for men and women.
The subject is then instructed to tell a story about the picture on each card, with specific instructions to include a description of the event in the picture, the developments that led up to the event, the thoughts and feelings of the people in the picture, and the outcome of the story. The examiner keeps the cards in a pile face down in front of him or her, gives them to the subject one at a time, and asks the subject to place each card face down as its story is completed. Administration of the TAT usually takes about an hour.
Murray's original practice was to take notes by hand on the subject's responses, including his or her nonverbal behaviors. Research has indicated, however, that a great deal of significant material is lost when notes are recorded in this way. As a result, some examiners now use a tape recorder to record subjects' answers. Another option involves asking the subject to write down his or her answers.
There are two basic approaches to interpreting responses to the TAT, called nomothetic and idiographic respectively. Nomothetic interpretation refers to the practice of establishing norms for answers from subjects in specific age, gender, racial, or educational level groups and then measuring a given subject's responses against those norms. Idiographic interpretation refers to evaluating the unique features of the subject's view of the world and relationships. Most psychologists would classify the TAT as better suited to idiographic than nomothetic interpretation.
I would be obliged to get your response.
