Also, "Theory of Mind is a theory insofar as the mind is not directly observable. The presumption that others have a mind is termed a theory of mind because each human can only intuit the existence of their own mind through introspection, and no one has direct access to the mind of another."
Children need to develop the ability to understand that another person has:
* a different point of view
Many parents want their children to get along with other children, and become adults who get along with others and have healthy relationships. As your child grows older, talk to them about the expressions on other people's faces, and their body language. Also talk about how others are behaving, and what they think the other person will be thinking and feeling. Sharing is one skill that toddlers find hard to master! Eventually we would like them to be able to interpret other people's words and behaviour.
So how does all this relate to reading to children? Pretend play, talking about other people's thoughts, wants and feelings, and hearing stories that involve choices characters and people made will strengthen Theory of Mind. Include stories where people have been tricked, mistakes were made, and anything that lends itself to discussion about a character's point of view. There are many good stories out there (fables, fairy tales etc.); in particular I like Enid Blyton and Aboriginal stories but there are many others.
Can you weave some questions into your daily reading routine, that aren't just about comprehension of the story (or big words), but are also about the characters' feelings and thoughts?
