You are studying the modal personality of a particular group of people by giving them Rorschach tests. In American society, a response to the white background (the PG on which the inkblots are placed) has been associated with the psychological trait of negativism. You are puzzled because you are getting a lot of white responses, but the people don’t appear to be negative in other respects. Then
you find out that their favorite color is white, and that they are treating the color of the PG not as a background but as a part of the design of the inkblot. This is an example of one of the problems faced by people trying to measure modal personality, which is that: a. people do not give consistent responses to the same picture from one day to the next. b. not everyone in a society has the same personality. c. tests devised in one cultural setting may not be appropriate in another. d. language problems can create misinterpretations. e. not everyone has the same type of eyesight.
