Fixations to extended Areas of Interest during generalization trials.

<p>Number of fixations to redefined (expanded) Area of Interest (AoI) where a stimulus could appear. For each AoI, left panels present the performance on trials where subjects categorized intervals as “short” and right panels correspond to categorizations as “long”; only intervals close to or at the extreme durations present mean of 15 subjects since some subjects never emitted erroneous categorizations. Stars and horizontal bars indicate significant differences between denoted groups after two-way ANOVA followed by Bonferroni´s test (p<0.05) (see text); only data from anchor intervals with N = 15 were included in statistical analysis.
