Developing Intuitions about How Personal and Social Properties Are Linked to the Brain and the Body

This study investigated the development of intuitions about which properties are associated with the brain and which are associated with the body. A sample of 60 children aged 6, 8, and 10 years, as well a sample of 20 adults, were told about a brain transplant between two individuals and were asked about where certain properties resided after the transplant. Adults and older children construed the characteristics associated with fine-motor behaviour, culpability, social contract and best friendships as transferring with the brain. Characteristics associated with gross-motor behaviour, physical/biological properties, ownership and familial relationships were more likely to be seen as remaining with the body. Domain-based explanations for this pattern of results are discussed.
