Ongoing work after publication has uncovered an inaccuracy in the reporting of one of the studies in this article.
The updated text replacing the first three lines of the methods section for Experiments 2a and 2b on page 1209 of the original article is set out below:
Both experiments were based upon the same picture and sound stimuli from Experiment 1 (see Figure 1b). The only difference in Experiment 2a was that the 4/8 critical relational trials from Experiment 1 that were preceded by an instruction from the informed director (and their 4 matched control trials) were now also spoken by the informed director. This design ensured that successful performance required participants to switch between the perspectives of the informed and ignorant director.
