Abstract:The impact of feedback on performance turned out to be inconsistent with respect to the significance of a wide range of moderating variables. Concerning personality traits, generalized self-efficacy, self-esteem, locus of control, and emotional stability have been shown to affect the processing of feedba ck. So far, feedback research has observed these traits in isolation, neglecting their interrelations. This study was carried out to investigate the impact of an integrative, higher order concept including these traits (termed as core self-evaluations) on the effects of feedback interventions. Participants (N = 471) received manipulated positive, negative or no feedback (control group) in the scope of two test performances conducted on the computer. Confirmatory factor analysis corroborated the concept of core self-evaluations. Repeated measures ANOVA did not reveal an effect of core self-evaluations on the impact of feedback. Considering the single traits, solely self-esteem turned out to affect the power of feedback.
