4.2.2 Seeing leads to knowing
Think back to the car parking example. Your judgement that your friend will go back to the original car parking place in Mount Street is actually a well-informed ‘guess’ based on evidence from your friend's behaviour. For instance your friend saw you parking the car and walked off without seeing you moving the car. We don't consciously run through such information before ‘calculating’ other peoples' states of mind. However, we are capable of making rapid, direct and non-conscious judgements of what other people are likely to know or believe, in part at least, from what perceptual information they have had access to. Baron-Cohen (1995) suggests that this seeing leads to knowing principle is grasped by typically developing children between 36 and 48 months of age.
