In the field of psychology, research areas often develop in relative isolation. Researchers in different areas are either not aware of, or seem to fail to see the relevance of findings from other areas even though it would seem that the findings are directly relevant to their own. One striking example of this is to be found in research that focuses on the effects of evaluation on performance. This volume integrates thinking from five different research traditions - achievement goals, intrinsic versus extrinsic motivation, goal setting, social loafing, and social facilitation - through the format of a give-and-take conversation between leading academics from each.
