It has been found that children appreciate the limited substitutability of co-referential terms in opaque contexts a year or two after they pass false belief tasks (e.g. Apperly and Robinson, 1998, 2001, 2003). This paper aims to explain this delay. Three- to six-year-old children were tested with stories where a protagonist was either only partially informed or had a false belief about a particular object. Only a few children had problems predicting the protagonist’s action based on his partial knowledge, when (...) he was only partially informed about a property of the desired object (e.g. he knew that it was a Lego® block, but not that it was a red Lego® block). But many had problems making the correct action prediction when he was only partially informed about dual identities (e.g. he knew it was a dog, but not that it was also an eraser). About as many children made an incorrect action prediction for partial knowledge problems involving dual identity as answered higher-order belief questions incorrectly. In contrast many more children answered first-order false belief questions correctly, as many as correct action predictions when the protagonist was partially informed about a property of an object. The results support the claim that children have a specific problem with dual identity, rather than a broader problem representing partial knowledge. (shrink)

Are incorrect judgments on false belief tasks better explained within the framework of a conceptual change theory or a bias theory? Conceptual change theory posits a change in the form of reasoning from 3 to 4 years old while bias theory posits that processing factors are responsible for errors among younger children. The results from three experiments showed that children who failed a test of false belief took as long to respond as those who passed, and both groups of children (...) took longer to respond to belief questions than to questions about prior states of reality. These results seem to support the bias theory. (shrink)

To understand why autistic people are misperceived in the way Jaswal & Akhtar suggest, we should embrace concepts like the “double empathy problem” and camouflaging and recognize the negative consequences these have for mental health in autism. Moreover, we need to value expertise from experience so that autistic people have a voice and indeed a stake in research into autism.

Various researchers have suggested that below 7 years of age children do not recognize that they are the authority on knowledge about themselves, a suggestion that seems counter-intuitive because it raises the possibility that children do not appreciate their privileged first-person access to their own minds. Unlike previous research, children in the current investigation quantified knowledge and even 5-year-olds tended to assign relatively more to themselves than to an adult (Studies 1 and 2). Indeed, children's estimations were different from ratings (...) made by their mothers: Their mothers sometimes rated themselves as knowing more about their child than they rated their child as knowing (Study 2). While previous research seemed to suggest that children shift from viewing their mother to viewing themselves as the authority on knowledge about them (the children), these new findings surprisingly suggest the opposite.

If anything, Carpendale & Lewis's (C&L's) target article could have gone even further in challenging the view that a radical conceptual shift equips children with a theory of mind. Also, the authors should have elaborated on why their social constructivist account is more plausible than nativism. Their argument against simulation theory is perhaps the least-developed part of their thesis, and does little service to their cause.
