Effects of Task Complexity and Goal Specificity on Change in Strategy and Performance Over Time

In this study we examined whether task complexity interacts with goal specific- ity over multiple performance periods. A 2 x 2 x 3 design manipulated goal condition (specific difficult vs. do-your-best) and task complexity (simple vs. complex) over performance on 3 separate days. Results across performance periods indicated that do-your-best goals led to higher quantity of performance than specific difficult goals on a complex task, whereas specific difficult goals led to higher quantity of performance than do-your-best goals on a simpler version of the task. Additionally, goal specificity and task complexity led to greater change in strategy over repeated performance periods, with those in the complex, specific difficult condition exhibiting the highest amount of change in strategy. Finally, there were no differences in quality of performance for indi- viduals working on simple versus complex tasks. Implications of these findings and directions for future research are discussed.
