Comparisons of the first fixation positions in Experiments 1–4 using two statistical methods: mixed-model repeated measures ANOVA and block bootstrapping (Boot). The statistical results from Experiment 4 only consider 16 observers who performed all four stimulus presentation conditions (see text). Notes: Statistical significance (Sig.) is determined by p < 0.05 in ANOVAs, and 95% confidence interval not including 0 in bootstrapping. The Cohen's d values consider all 54 observers in Experiments 1, 2, and 4. A: Asian. C: Caucasian. NS: Not significant.
