Outcome feedback manipulation check and psychological reactions to outcome feedback
As a manipulation check, we analyzed ratings of perceived competition using a one-way ANOVA with outcome feedback (victory vs. defeat vs. uncertain competitive outcome vs. control) as a between-participant factor. We observed a significant effect of outcome feedback (To examine psychological reactions to outcome feedback, we performed three separate one-way ANOVA on the ratings of self-confidence, closeness, and trust. Regarding self-confidence, we found a significant effect of outcome feedback (Effect of outcome feedback on participants’ self-reported measures. The graphs in (These findings suggest that interpersonal trust was modulated by competition-outcome feedback rather than competition participation without relative performance feedback. They consistently demonstrate that self-evaluation, as captured by self-confidence, and interpersonal relationships, as measured by closeness and trust, were susceptible to competition with outcome feedback rather than competition without outcome feedback.
