The current study examines how the interaction of self-construal (independent and interdependent) and expectancy (optimism and pessimism) impacts motivation. Both self-construals and expectancies were experimentally manipulated, after which participants completed a word anagram task. Motivation was measured as the total amount of words created (performance) and the amount of anagrams taken home (persistence). The findings of the study showed that self-construal and expectancy did not interact together as hypothesized. While interdependents who were pessimistic did show signs of persistence, many of the results were null or implied that independent benefited from pessimistic expectancies. Discussion centers on the potential implications of these findings on patient compliance and how these could be used in the field of physical therapy specifically.
