2.2. Setting and material

The experiment was conducted in a quiet room free from distraction, located at the school which children attended. Participants were exposed to the experimental procedures individually in two sessions. Sessions could be terminated upon the child's request at any time (although this never occurred). The perspective-taking tasks consisted of different deictic relations protocols (explained in the Procedure) which included the three types of deictic frames (i.e., I-You, Here-There, and Now-Then) and the three levels of relational complexity (i.e., simple, reversed, and double reversed) used in the Barnes-Holmes protocol.
