SA Crea = Self-assessed creative performance; Absolute/Relative = Self-assessment in general/compared to others; Pre/Post = Self-assessments assessed pre/post DT task performance. n_{Study 1} = 425. n_{Study 2} = 317. * = significant after Bonferroni-correction (.05/4: p < 0.013). Confidence intervals are based on 2,000 bootstrap samples. Positive values for t and d indicate that measured creativity is higher than self-assessed creativity (i.e., overestimation).
