The Thurstone scale is constructed using the method of equal-appearing intervals, which involves selecting a pool of statements or items relevant to the construct being measured and then having judges rate them on a continuum from strongly agree to strongly disagree. The items are then sorted into groups based on their similarity in rating by the judges, and a set of items representing each group is selected to create the final scale. The result is a scale with items that have equal-appearing intervals between them, allowing for more precise measurement of the construct. The Likert and semantic differential scales are both constructed using the method of summated ratings, in which respondents rate their level of agreement or disagreement with a set of statements or items. The TAT (Thematic Apperception Test) is a projective technique that involves interpreting ambiguous pictures to reveal underlying motivations or thought patterns, but it is not a rating scale.
