INTERACTION AND INTERSECTION: THE CONSTELLATION OF EMOTIONAL STABILITY AND EXTRAVERSION IN PREDICTING PERFORMANCE
研究了大五人格中的情绪稳定性和外向性如何组合预测工作绩效，发现两者的组合（反映“快乐”或“乐观”人格）比单独一个特质更重要。
This study investigated the constellation of 2 Big 5 traits—Emotional Stability and Extraversion—in predicting job performance. Two forms of the constellation, one indirect (a statistical interaction) and the other direct (a measure of the intersection between the traits from the Big 5 circumplex), were used to predict job performance. Data were collected from employees and their supervisors at a regional health and fitness center. Results indicated that both measures predicted performance, even when controlling for the “main effects” of Emotional Stability and Extraversion, as well as 2 other relevant Big 5 traits (Agreeableness and Conscientiousness). These results suggest that the combination of Emotional Stability and Extraversion—reflecting a “happy” or “buoyant” personality—may be more important to performance than either trait in isolation.
