Procedure and results in Experiment 2. (a) An example of the trial in the object categorization task with Predictive-valid group gazes and an office item as the target; (b) examples of the trial to choose trustworthy group (upper panel) or single (lower panel) face(s) in the face-choice task; (c) RT results in the object categorization task; (d) results of percentage choosing the Predictive-valid group as more trustworthy, and the dashed line represents the 50% chance level. The dots in (c) and (d) are individual data points making up each group. The asterisk represents a significant difference between two corresponding conditions or from the chance level (p < 0.05), and the error bar represents one S.E.M.
