Fig. 1 Events shown in experiment one. (A to F) Familiarization. (G to J) Belief induction for the FB1 (false belief one) condition. (K) Central approach for FB1. (L to O) Belief induction for FB2. (P) Central approach for FB2. (Q) Areas of interest (AOIs) defined for the target and distractor haystacks. See movie S1.
Fig. 2 Events shown in experiment two. (A to G) Familiarization. (H to M) Belief induction for the FB1 condition. (N) Central reach for FB1. (O to S) Belief induction for FB2. (T) Central reach for FB2. (U) AOIs defined for the target and distractor boxes. Following the infant study (10), we included an additional action in FB1 [KK touched the distractor box (K)] to control for subjects looking to the last place that the actor attended. See movie S2.
- Table 1 Number of participants who made first looks to either the target or the distractor during the agent’s approach in experiments one (N = 40) and two (N = 30).
Values in parentheses indicate the number of participants who did not look at either.
