The reciprocal effects of science on practice: Insights from the practice and science of goal setting.

Abstract

Abstract The hypothesis of this paper is that the science and practice of psychology are interdependent. Science drives practice which drives science. The science and practice of 25 years of programmatic research on goal setting theory in industrial-organizational (1/0) psychology is used in support of this hypothesis. Scientists, practitioners, and scientist-practitioners alike are encouraged to work in unison in order to advance psychology for all. The Smothers brothers, two comedians, have made millions of dollars from one sentence: Mom always liked you best. People laugh in empathy recalling how as the older child, only the baby sat on mom's knee, or as the younger child recalling that only the older child was granted special privileges. The Smothers brothers' description of their relationship is not unlike the description one can make of the Canadian Psychological Association (CPA) in that many practitioners feel strongly that CPA exists primarily for scientists; many scientists know that CPA exists primarily for practitioners. The hypothesis of this paper is that the science and practice of psychology are interdependent rather than a dichotomy. Scientific theories in psychology provide frameworks for practice. They facilitate the development of effective methodologies as well as provide a basis for understanding the success or failure of a predictor or an intervention (Latham & Crandall, 1991). They thus provide a basis for predicting, understanding, and influencing what people say and do. Practice provides evidence for the external validity of a scientific theory. Practice facilitates the abandonment, modification or improvement of theory through subsequent hypothesis testing in both the field and in laboratory settings. In short, practice suggests refinements to theory, and the refined theory provides an improvement in guidelines for effective practice. An illustration of this bidirectional refinement is the science and practice of goal setting theory in industrial-organizational (I/o) psychology. I/0 psychology explicitly embraces the scientist-practitioner model. GOAL SETTING THEORY The core findings of Locke and Latham's (1990) goal setting theory are that: (1) Specific high goals lead to higher performance than setting no goals or setting an abstract goal such as do your best; (2) There is a linear relationship between goal difficulty and performance. Thus the higher the goal the higher the performance; (3) Variables such as feedback, participation in decision making, and competition only affect performance to the extent that they lead to the setting of and commitment to specific high goals; (4) Three of the four mediators of the goal setting performance relationship are motives tional, namely direction, effort, and persistence; the fourth is cognitive, namely, task strategies. Moderators of the effect of goals on performance are ability, commitment, feedback, task complexity, and situational constr-aints. The immediate empirical origin of this theory can be found in Locke's (1964) doctor-al dissertation as well as a series of laboratory experiments that he conducted shortly thereafter (Locke, 1968). The dependent variables in his experiments included mathematical problems, making words from anagrams, as well as creating toys. On the scientist-practitioner continuum, Locke places himself on the scientific end, although he has had a practice in clinical psychology and continues to have a consulting relationship with organizations in the public and private sector. I, on the other hand, view myself on the practitioner side of the continuum although I conduct research in both field and laboratory settings, and I hold a full-time position in an academic institution. My consulting practice is incorporated in Canada and in the United States. Locke and I have collaborated productively for 25 years. We view one another as scientistspractitioners.
