A theory-based intervention to prevent calibration effects in serial sport performance evaluations

ObjectivesSerial performance evaluations show calibration effects: Judges avoid extreme categories in the beginning (e.g. best or worst) because they need to calibrate an internal judgment scale (Unkelbach et al., 2012). Successful calibration is therefore important for fair and unbiased evaluations. A central prerequisite for successful calibration is knowledge about the performance range. The present study tests whether advance knowledge about the range (best and worst) of performances in a series reduces calibration effects.DesignA 2 × 2 × 2 design was developed with two between subject factors: the knowledge about the performance range (with vs. without) and two different talent tests (specific vs. unspecific). As within subject factor the position of the performances in the series (position 1–10 vs. 11–20) was integrated. The combination of the between subject factors resulted in four experimental conditions.MethodHandball coaches were randomly assigned to one of the conditions. Afterwards twenty performances were evaluated in a randomized order by the coaches.ResultsWithout knowledge about the range, they showed the expected avoidance of extreme categories in the beginning independent of the presented talent test. However, observing the best and worst performance in advance prevented the biases. Range-presentation is therefore a viable theory-based intervention to improve fairness in serial judgments.     

Friendship network mechanisms linking emotional intelligence and subjective well-being: Beyond a mediation model

ABSTRACT

This study examined whether the status (central or peripheral position) of individuals in a friendship network and the quality of a friendship network represent key mechanisms in determining how emotional intelligence is associated with subjective well-being. Using data collected from 217 Chinese senior undergraduates, we found that the interaction of the quality of a friendship network and a peripheral position in a friendship network mediated relations of emotional intelligence with subjective well-being. Although a central position in a friendship network did not interact with the quality of a friendship network, it did mediate the relations of emotional intelligence with subjective well-being on its own. The findings expand the growing body of research findings on the association between emotional intelligence and subjective well-being by investigating the role of friendship networks and highlight the importance of a network perspective in understanding the association.
