"It's some bizarre, weirdly out-of-proportion fixation," Ms. Faludi said, "an exaltation of American masculinity in an intergalactic crisis".
Thus, with increased age, infants spent an increasingly greater amount of the time fixating on the eyes of own-race faces, whereas the proportion of fixation time on the eyes of other-race faces remained largely unchanged with age (Figure 2).
For the proportion of fixation time on the mouth, we calculated Pearson correlations between the infants' ages in days and the proportion of fixation time on either the other- or own-race mouth, respectively.
For the proportion of fixation time on the nose, we calculated Pearson correlations between the infants' ages in days and the proportion of fixation time on either the other- or own-race nose, respectively.
The age in days was significantly and positively correlated with the proportion of fixation time on the own-race eyes (r 37) = .51, p = .001), but not with other-race eyes (r 37) = .19, p = .259).259
The age in days was not significantly correlated with the proportion of fixation time on the nose of either the other- or own-race faces, r 37) = −.10, p = .573, and r 37) = .00, p = .999.999
The age in days was significantly and negatively correlated with the proportion of fixation time on the mouth of the own-race faces, r 37) = −.34, p = .029, but not with the fixation time on the mouth of the other-race faces, r 37) = .08, p = .623.623
A 2 (race: own versus other)×3 (feature: eyes, nose, mouth)×1 (age in days: continuous variable) repeated measures ANOVA was performed using the proportion of fixation time on eyes, nose, and mouth as the dependent variable and age in days as a continuous variable.
(D ) Proportion of fixation breaks of the total number of trials (open circles, mean ± SEM) for each speed sorted by the boundary position.
A t-test comparing the proportion of fixations of the car (when on the screen) for each group confirmed that participants in the Comprehension group fixated the car significantly more often (10.2% of fixations) than participants in the Map task group (6.5% of fixations) (t (100) = 3.706, p < 0.001; d = 0.74).
A t-test comparing the proportion of fixations on the car between each condition was not statistically significant (t (82) = 1.73, p = 0.087; d = 0.382), and the Bayes factor showed anecdotal evidence for the null, namely the Tyranny of Film hypothesis (BF01 = 1.52).
