T.A.T. was designed by ______.

Concept: A projective personality test presents an ambiguous stimulus — an inkblot, an incomplete sentence, or a picture — and asks the person to interpret it or respond freely. Because the material has no single fixed reading, the response is assumed to project the person's own unconscious needs, motives, and conflicts onto it.

Application: The Thematic Apperception Test (T.A.T.) applies this idea using a set of ambiguous picture cards showing people in vague situations; the test-taker must invent a story for each card (what led up to it, what is happening, how it ends). It was designed by Henry A. Murray, working with Christiana D. Morgan at the Harvard Psychological Clinic, in the early 1930s, growing out of Murray's need-press theory of personality — the invented stories are analysed for the recurring needs and social pressures (“presses”) they reveal.

Cross-check: weighing the other names offered against their actual contribution rules each one out.

• Rorschach test — a different projective technique built on symmetrical inkblot cards rather than picture-story cards; created by Hermann Rorschach, not the T.A.T.

• Gordon Allport — remembered for trait theory, describing personality through cardinal, central, and secondary traits, not for constructing a projective test.

• Abraham Maslow — remembered for the humanistic hierarchy-of-needs theory, not for designing a projective testing instrument.

So, among the names offered, only Murray designed the T.A.T.
