Sensitivity theory provides an analysis of personality based on what people say motivates their behavior. After Reiss and Havercamp (1998) confirmed a 15-factor solution to self-reported human strivings, the Reiss Profile of Fundamental Goals and Motivation Sensitivities (Reiss & Havercamp, 1998) psychometric instrument was standardized. In 3 studies, the Reiss Profile was shown to possess good...
