Theory of Mind Flashcards
How do we make sense of others’ behaviour?
We try and figure out what someone is trying to do, what they want to do and what they are thinking
What does making sense of other peoples’ behaviour require?
That we view others’ as intentional agents - we do things to achieve goals/cause things to happen
An ability to take another person’s perspective
What is the Theory of Mind?
Attributing (unobservable) mental states (thoughts, feelings, beliefs, desires, intentions) to others
Who created the Theory of Mind?
Premack & Woodruff (1978)
A big part of ToM is the understanding that people’s desires, beliefs and thoughts about the world can be…
Different to our own
Wrong (a false belief)
What is ToM important for?
Understanding literature Intentional communication with others Repairing failed communication with others Teaching others Persuading others Deceiving other people Building and sharing plans and goals Pretending
What is a crucial test of ToM in children?
The ability to attribute false beliefs
Standard false belief task
Character A places an item in box A
Without character A knowing, the item is moved to box B by character B
Child asked where will character A look for the item
Results of standard false belief task
Is the child able to attribute the false belief to the character and say box A, where they originally put the item
Who did the standard false belief test?
Wimmer & Perner (1983)
Frith (2003)
‘Sally-Anne’ false belief task (Frith, 2003)
Sally has a basket
Anne has a box
Sally has a marble, she puts it in her basket and leaves
Anne takes the marble and puts it in her box
Where will Sally look for the marble?
Results of Sally-Anne test
To succeed, the child must separate their own (true) belief from other peoples and attribute a false belief to Sally
4 year olds tend to pass
3 year olds tend to fail
Sabbath et al (2006)
The pattern of ToM performance is reported across the globe
Avis & Harris (1991)
Even children living in remote rainforests in Cameroon report the same pattern of performance in the ToM task
The Smarties Test Part A (Perner, Leekam & Wimmer, 1987)
A child is shown a smarties tube and asked what is inside
Naturally they say smarties
But then they are shown pencils inside
Then asked what they think another child who hasn’t seen inside will say
The Smarties Test Part A results
3 year olds say pencils (their current understanding)
4 year olds say smarties (what they know the other children understand)
The Smarties Test Part B
Children are asked what they would have thought was inside the smarties tube if they hadn’t seen inside
The Smarties Test Part B results
3 year olds fail as they have a poor understanding of even their own beliefs
4 year olds pass
At what age can children use the idea of false beliefs to predict when a person will be surprised?
5 years old
Hadwin & Perner (1991)
Tommy test
Told about a boy called Tommy who loves chocolate and his mum bought him some smarties
The experimenter replaced the smarties with jelly babies
Asked what Tommy would think is inside and asked to choose a neutral or surprised facial expression
Tommy test results
4 and 5 year olds knew that Tommy would look at the box and think there were smarties in it
Only 5 year olds were able to say that Tommy would be surprised
What does this anecdote show?
Sarah (age 3): ‘Mummy, go out of the kitchen’
Mum: ‘Why?’
Sarah: ‘Because I want to take a cookie.’
Young children don’t understand that they need to deceive someone (deprive them of knowledge) if they want something they are not allowed
