*Indicates statistically significant at the 0.05 level; ${\eta }^2$ represents the proportion of the total variance in the DV that can be explained by the factor; only ${\eta }^2$ for significant results are shown; residual df = 635; a bold ${\eta }^2$ represents an effect size above the cutoff of 0.03.
