Situations are selected to be typical of those in which the individual’s performance is to be predicted. . . .[Each] situation is made sufficiently complex that is very difficult for the persons tested to know which of their reactions are being scored and for what variables. There seems to be much informal evidence (face validity) that the person tested behaves spontaneously and naturally in these situations. . . . It is hoped that the naturalness of the situations results in more valid and typical responses than are obtained from other approaches. (p.462)
