One hundred nineteen out of 180 comparisons (61%) of the 5 within-rater trials were not significantly different (p >0.05). In these cases, raters made judgments of imitativeness consistently across rating blocks. The remaining 39% of the comparisons (shaded in gray), however, showed significant differences across ratings [χ2(9) = 143.32, p < 0.001], suggesting raters changed their decision patterns for ratings of imitativeness across the five trial blocks.
