This research examined how performance feedback moderates the effects of individuals' achievement goals on information exchange when carrying out a novel and complex task. Experiment 1 demonstrated that mastery goal individuals who received positive performance feedback gave less modified information about their task performance to their exchange partner relative to both mastery goal individuals who received negative feedback and performance goal individuals (who received either negative or positive feedback). In Experiment 2, we found that relative to performance goals, mastery goals led to a stronger reciprocity orientation and a weaker exploitation orientation. Also, mastery goal individuals provided information of higher quality than performance goal individuals, thereby explaining the observed findings in Experiment 1.Information exchange may be helpful to acquire task-related problem solutions, particularly when people are engaged in carrying out new and complex tasks. However, the ability to give meaningful task-related information to others at a certain point during task execution depends on the performance level one has actually reached at that point. To make an assessment of their current task proficiency, individuals often use feedback information about the effects of their task activities they obtain from the task process itself or from constituents in the task environment. For example, when a coworker asks you how to use a specific software package that you yourself just successfully have learned to use, it is probably easy for you to provide this coworker with useful information. However, if you are still unable to operate the program yourself, it is obviously much harder for you to give your colleague meaningful information and you may therefore decide to invest extra effort in enhancing your skills before starting to provide your colleague with advice to use the program.Although task-related information exchange may take place without any ulterior motive, in this article we argue that people often use information giving to facilitate the attainment of their achievement goals. Achievement goals reflect the aim for an individual's achievement pursuits in a particular situation (Elliot, 2005). Take, for example, a young and high-performing lawyer who wants to exchange information with coworkers to further enhance her job-related performance. With her high task performance in mind, she may decide to share relevant information with a particular associate. This information giving goes hand in hand with the possibility of receiving desired information back, either immediately or at a later time, and thus might eventually contribute to further improving her individual jobrelated skills and enhancing her job performance.However, when the same lawyer has received feedback indicating that she is performing rather poorly, she may find herself in a difficult position of not being able to give her partner valuable task information, unless she first makes an investment in her task performance.
