Figure 9. Mean comprehension question accuracy in Experiment 3 (N=40).

Vertical lines depict standard error of the means, and the horizontal line indicates an accuracy score of 50% (chance). The difference between accuracy for unambiguous and ambiguous singular stimuli was significant at p < .001. The difference between accuracy for unambiguous and ambiguous plural stimuli was also significant at p < .01. **p < .01; ***p < .001.
