McClelland utilized a method of showing the subject an ambiguous image and having them write a story about it. The concept that suggests that such an approach might reveal underlying needs of the subject is a) Self-reference Criterion: we interpret our environment based on our previous experiences. b) Equity Theory: we desire fairness, so we will tell a story that is fair with respect to the characters in the image. c) Fundamental Attribution Bias: we blame ourselves for the bad things that happen in life. d) None of these.
