When people are trained in the proper strategies, those given specific high-performance goals are more likely to use those strategies than people given other types of goals; hence, their performance improves (Earley & Perry, 1987). However, if the strategy used by the person is inappropriate, then a difficult performance-outcome goal leads to worse performance than an easy goal (Audia, Locke, & Smith, 2000; Earley & Perry, 1987). For a detailed discussion of the relation of task goals and knowledge, see Locke (2000).
