We would like to thank Michael M. Harris and Filip Lievens for their comments on an earlier version of this paper and Marc Covents for his programming work on the webbased work simulation. The aim of the current study is to shed new light on the inconsistent relationship between performance-approach goals and feedback reactions by examining feedback type as a moderator. Results of a field experiment (N = 939) using a web-based work simulation task showed that the effect of achievement-approach goals was moderated by feedback type. Relative to individuals pursuing mastery-approach goals, individuals pursuing performance-approach goals responded more negatively to comparative feedback but not to task-referenced feedback. In line with the hypothesized mediated moderation model, the interaction between achievement goals and feedback type also indirectly affected task performance through feedback reactions. Providing employees with feedback is a key psychological principle used in a wide range of human resource and performance management instruments (e.g., developmental assessment centers, multi-source/360 degrees feedback, training, selection, performance appraisal, management education, computer-adaptive testing, and coaching). The current study suggests that organizations need to strike a balance between encouraging learning and encouraging performance, as too much emphasis on comparative performance (both in goal inducement and in feedback style) may be detrimental to employees' reactions and rate of performance improvement. The achievement goal approach to achievement motivation has emerged as a highly influential framework for understanding how people define, experience, and respond to competence-relevant situations (Elliot, 2005). Although there are some differences among achievement goal theorists regarding the exact nature and functioning of these goals, they generally agree that three achievement goals can be distinguished (e.g., Elliot and Church, 1997;VandeWalle, 1997). Mastery-approach (MAp) goals imply that the individual is focused on the development of one's competence and thus, involve an emphasis on intrapersonal standards. The purpose of mastery-approach goal individuals is to learn and to improve on the task at hand, and ultimately, to achieve complete mastery of the task. Performance goals, in contrast, are grounded in interpersonal standards and may either emphasize the attainment of competence relative to others, or the avoidance of incompetence relative to others.These goals are referred to as performance-approach (PAp) goals and performanceavoidance (PAv) goals, respectively (Elliot, 2005).The general picture arising from two decades of research is that MAp goals are most adaptive for learning outcomes, whereas PAv goals are consistently associated with unwanted effects (e.g., Elliot, 1999Elliot, , 2005Payne, Youngcourt, & Beaubien, 2007).For PAp goals, the story has been mixed. Some studies reported that these goals were associated with positive outcomes such as persistence, effort, task int...
