  1. Significant effects (p < 0.05) are bolded. ptime = p-value of time effect, pin t = p-value of interaction effect between time and a predictor. IP1 = “People tend to believe I am more competent than I really am,” IP2 = “I tend to feel like a phony,” IP3 = “Sometimes I’m afraid others will discover how much knowledge I really lack.”GM1 = “Becoming a top, productive scientist is possible for everyone through effort and practice,” GM2 = “Success in science is pretty much related to how much effort a person makes”
