Yed that T wanted to keep O ignorant about her (T’s) interest inside the rattling toys: in each rattlingtoy trial, T picked up the toy only after O left, and she swiftly returned it towards the tray when O knocked to announce her return. Prior analysis indicates that infants within the 2nd year of life are adept at tracking which agents are knowledgeable or ignorant about events within a scene (e.g Liszkowski, Carpenter, Tomasello, 2008; Scott et al 200; Song et al 2008; Tomasello Haberl, 2003). Thus, the infants in the deception situation must understand that T regularly played using the rattling toys only in the course of O’s absence and therefore with no her understanding. Third, within the test trial, and for the first time in the testing session, O introduced a rattling toy that was visually identical to a silent toy she had previously discarded. Soon after O left, T stole this rattling toy by hiding it in her pocket. Prior investigation indicates that infants in the 2nd year of life currently have an understanding of stealingor taking away the toy a person has been playing withas a adverse, antisocial action (e.g Hamlin, Mahajan, Liberman, Wynn, 203; Hamlin, Wynn, Bloom, Mahajan, 20). The infants within the deception situation must for that reason recognize that T meant to steal the rattling test toy when she hid it in her pocket. Fourth, T did not merely steal the rattling test toy: she also placed among the list of discarded silent toys on the tray, suggesting that she wanted her theft to go unnoticed by O (this was constant with T’s secretive behavior in the course of the familiarization trials). By replacing the rattling test toy together with the matching silent toy, T could achieve her deceptive target: when O returned, she would mistake the matching silent toy for the rattling toy she had left behind. As discussed earlier, prior study suggests that four.five to 8montholds may perhaps be able to attribute to an agent a false belief concerning the identity of an PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/24382994 object (Buttelmann et al 205; Scott Baillargeon, 2009; Song Baillargeon, 2008). If 7montholds can appreciate not just the point of view of an agent who holds such a false belief, but in addition the viewpoint of an agent who seeks to implant such a false belief, then the infants inside the deception condition ought to recognize that by substituting the matching silent toy, T wanted O to believe it was the rattling toy she had left behind. To summarize, the mentalistic account predicted that the infants within the deception situation would construct a causally coherent interpretation of T’s actions that involved a number of, interlocking mental states: (a) T had a preference for the rattling toys; (b) when OAuthor Manuscript Author Manuscript Author Manuscript Author ManuscriptCogn Psychol.

Lastly, the mentalistic account predicted that the infants inside the silentcontrol condition would be unable to build a causally coherent interpretation of T’s actions in either trial and therefore would look about equally irrespective of whether they received the nonmatching or the matching.
