Recent research supports the position that understanding of false beliefs is a fundamental cognitive capacity, present early in human development (as young as 13 months). But what is necessary for this capacity to develop?
Gary's team conducted two experiments, looking at deaf and hearing children aged 16 to 36 months. The children were grouped according to whether they or their parents were hearing or deaf. When the researchers tested whether the children were able to track the true and false beliefs of a cartoon character, only the deaf children with hearing parents were unsuccessful - children without early access to a language.
Next, they looked at how much language about the mind was used in conversations with deaf infants. Hearing mothers of deaf infants used words like “think”, “know”, and “want” far less than did their signing deaf counterparts.
These findings together support the position that access to a least a minimum of talk about the mind either in a spoken or signed language contributes decisively to the expression of Theory of Mind reasoning - even in very early human development.
