Note. Duration and frequency values (estimated marginal means ± SE) shown are log-transformed proportion values, adjusted for the total duration and number of fixations recorded for each slide. Wald χ² and p-values are those obtained for the best-fitting mixed-effects models for the respective outcome variables, including a subject-level random intercept and a random coefficient for level of picture systemizing. df = 10 for all models.
