In two investigations (N = 62 and 59), three- and four-year-old childr
en sometimes disbelieved what they were told about the unexpected cont
ents of a deceptive box, even when they had seen the adult speaker loo
k inside the box before s/he told them what s/he saw, and despite bein
g able to recall the utterance: utterances were treated as unreliable
sources of knowledge compared with seeing directly. Those who did beli
eve the utterance were no better at recalling their prior belief about
the box's contents (now treated as false), than those who saw inside
the box. However using a narrative procedure, we replicated Zaitchik's
(1991) result that children are more likely to acknowledge another's
belief when they are told about reality, than when they see reality fo
r themselves. We argue that these children were acknowledging alternat
ive rather than false belief.
