Lecture 4- Theory of Mind Flashcards
what is theory of mind
the capacity we have to predict and explain other peoples behaviours in terms of their internal states of mind
e.g. if you desire something, you look for it in a place where your beliefs make you think but if you do not find it, your reaction may be of surprise
origins of ToM-premack + woodruff 1978
2 examples
1- food is hanging off a branch at a height that cannot be reached by stretching
in the cage there are several objects, one is a stool which can be used to reach the food
2- a human tries to get out of a locked cage, the key is outside the cage that cannot be reached
in the cage there are several objects, one is a wooden stick which can be used to reach the key
there is understanding of the human’s needs and beliefs- they have ToM
critical question
how do we know people are understanding the needs and beliefs of others rather than just coming up with a solution
what would be an appropriate test to assess an understanding of other people’s mental states?
the child is required to attribute a belief to another person which is different to their own.
the participant cannot predict the correct response on the basis of what they know to be true
if the child can predict what another person will do on the basis of a false belief, we know that they are not just reading the answer from scenario
false belief task
sally ann
wimmer+perner 1983
baren-cohen, leslie+frith 1985
sally puts marble in basket, goes outside to play, ann moves marble to box, sally comes back
then the child is asked “where does sally think the marble is?”
sally has false belief about the location because she has not seen ann move it- their answer should be basket
the child has to ignore what they know
false belief task
sally ann
results
4-4.5 years of age, children give the correct answer and hence have ToM
2 years old answer where the marble is and hence do not have ToM
false belief task
sally ann
modification
4 years old control question
asked why does sally think the object is in here?
because sally hasn’t seen it move
gives correct answer for correct reason
false belief task
sally ann
modification
siegal +beattie 1991
modified by asking the child “where will sally look first of all” instead on “where will sally look for her marble”
the control group will be asked the same original question
39% of 3yr olds passed original whereas 70+% passed modified
false belief task
appearance reality task
a child is shown an object and is asked “what does it look like”
3yr old= a stone
the child is given the opportunity to play with the object + to verify it is soft and light
they are then asked “so, what is it really”
3 yr old= its a sponge
the child is then asked “what does it look like”
3 yr old= a sponge; should answer a stone
false belief task
appearance reality task
conclusion
3yr olds are unable to capture the difference between appearance and reality
they are unable to attribute a thought about the object independent of what the object is
false belief task
deceptive box task
a child is show a box of smarties and is asked “what is in the box”
3 yr old=smarties
the experimenter opens the box and shows the child there is a pencil inside, the child is then asked “what is in the box”
3 yr old=pencil
the child is then asked “ what do you think another child would think is in the box?2
3 yr old=pencil; another child will think a pencil is in the box
false belief task
deceptive box task
conclusion
3yr olds are unable to capture the difference between appearance and reality
false belief task
deceptive box task
modification
mitchell+locohee 1991
boosted the idea of smarties being in the box by getting children to post a picture of a smarties box
20% of children passed original
60% passed modification
Leslie 1987/1988
suggested
that as beliefs are represented in the mind, we can understand that something represent others and hence believe some things can misrepresent others
false photograph task
zaitchik 1990
involves representation but not mental states
the child is shown how a polaroid camera works and takes a picture of a cat sitting on a chair.
the researcher moves the cat to the bed and the child gets asked “where is the cat in the picture?”
3 yr olds fail=say bed
