Theory of Mind Flashcards
Premack & Woodruff (1978) say Theory of Mind is
Attributing mental states (thoughts, beliefs, intentions etc) to others
Theory of Mind allows us to
Predict others behaviour
A big part of understanding theory of mind is that
Peoples mental states can be different to our own
Bjorklund (2012)
An ability to make sense of other peoples behaviour requires two things.
- That we view others as ‘intentional agents’
2. An ability to take another person’s perspective
Why is theory of mind important?
Help us understand/explain/predict others behaviour
Who said ToM is important for:
Understanding art/literature Intentional communication Repairing failed communication Teaching others Persuading others
Baron-Cohen (1999)
How is ToM measured in children?
Standard false belief task (e.g. Sally-Anne test)
Sally-Anne test
What must children to do succeed? (2)
Separate their own (true) beliefs from other peoples
Attribute false belief to Sally
Sally-Anne test
Who passes?
4 year olds
Sally-Anne test
Who fails?
3 year olds
Hadwin + Perner, 1991
At age 5, children use false beliefs….
To predict when person is surprised
Hadwin + Perner, 1991
Method
Tommy who loved chocolate study
Experimenter replaced smarties with sweets
Hadwin + Perner, 1991
Both 4 and 5 year olds knew
Tommy would think there would be smarties in the box (false belief)
Hadwin + Perner, 1991
Only 5 year olds…
Said Tommy would be surprised when he opened the box
Wellman et al., 2001
When does ToM first develop?
Age 4 in false belief tasks
Sabbagh et al., 2006
Avis + Harris, 1991
Where else has ToM been found in children?
- Across the globe
- Remote rainforests in Cameroon
Peskin 1992
When does deception emerge?
Age 5
Why does deception emerge at age 5?
Young children do not think they can deprive someone of knowledge + deceive them
Peskin 1992
What did this study aim to measure?
Deception
Peskin 1992
Method
Children picked liked/disliked sticker
Naughty puppet
Asked which sticker they like
Peskin 1992
3 year olds ………. even after ………
Did not deceive
Practice
Peskin 1992
4 year olds…..(2)
- Didn’t spontaneously deceive
2. Did after practice
Peskin 1992
5 year olds…
Deceived
Ding et al., 2015
Theory of mind does seem to be causally related
To the ability to lie
Ding et al., 2015
Participants + Method
3 year olds
Group 1: ToM skills
Group 2: Physical concepts (control)
Ding et al., 2015
Which group was more likely to lie after training?
ToM group
Woodward (1998)
Infants as young as _______ understand people act on their intentions
6 months
“Understanding people act on their intentions”
This is a…
Basic building block of ToM
Woodward (1998)
6 month olds look…
Longer when actor reaches towards different object than before
Woodward (1998)
3 month olds…
No difference in looking between new scene and old scene
Woodward (1998)
Infants as young as 6 months may understand
Others as intentional agents
Leslie, 1987
Understanding mental states
Two year olds understand
Their thoughts can be different from the state of reality
Leslie, 1987
Understanding mental states
2 y/o’s understand their thoughts can be different from reality. How is this shown?
Through pretend play
Estes, Wellman + Woolley, 1989
Understanding mental states
3 year olds have an awareness thoughts exist. For example
They understand mental entities have different properties to physical ones
From around 2, children start using words like
Want, see, taste
From around 3, children start using words involving _______, like
Cog. states
Know, think
If a child uses ‘know’ and ‘think’ together, this shows an understanding of
Contrasting mental states - reality vs belief
Shatz et al., 1983
Using the words ‘know’ and ‘think’ shows an understanding of
Contrasting mental states - reality vs belief
Repacholi + Gopnik (1997)
Understanding desires
Method (4)
- R presents two bowls of food (crackers or broccoli)
- Child says what they prefer
- Experimenter shows which they prefer
- Asks for more
Repacholi + Gopnik (1997)
Understanding desires
18 month old infants give….
Researcher the preferred food, regardless of personal preferred food
Repacholi + Gopnik (1997)
Understanding desires
18 month old infants give the researcher their preferred food, regardless of
Their own personal preferred food
Repacholi + Gopnik (1997)
Understanding desires
14 month old infants…
Give the experimenter their OWN preferred food
Onishi + Baillargeon, 2005
Tested ______ in infancy
False beliefs
Onishi + Baillargeon, 2005
Key RQs? (2)
- Will infants look longer when surprising reach is made
2. Variation depending on whether eyes are covered?
Onishi + Baillargeon, 2005
If actors eyes are covered and a box is switched, this is a _________ condition
False belief
Onishi + Baillargeon, 2005
If actors eyes aren’t covered and a box is switched, this is a ___________ condition
True belief
Onishi + Baillargeon, 2005
Which conditions did infants look longer in? (2)
Wrong box yet not blindfolded
Right box yet blindfolded
Onishi + Baillargeon, 2005
Why did infants look longer in the wrong box/not-blindfolded condition?
Actor saw the switch - surely they should know to look in new location?
Onishi + Baillargeon, 2005
Conclusion: infants understand the actor
Has a false belief
It is hard to reconcile the finding that 15-month-olds understand false beliefs but fail false belief tasks at age 3.
How can we explain this?
There may be two ToM systems
Implicit
Explicit
Leslie, German + Polizzi (2005)
______ ToM and _____________ ToM
Implicit
Explicit
Leslie, German + Polizzi (2005)
What is implicit ToM? (3)
Innate
There without awareness
Can’t be expressed verbally
Leslie, German + Polizzi (2005)
What is explicit ToM? (2)
Learned slowly
With awareness
Clements + Perner, 1994
Despite failing false belief tasks verbally, 3 year olds…
Usually LOOK at right box
Clements + Perner, 1994
3 year olds who fail false belief tasks usually look at box where character should look. This indicates they
Might know the correct answer but do not express it
3 Theories of ToM development

Theory-Theory (_______)
Wellman, 1990
Theory-Theory
2 year olds have a theory based on

Theory-Theory
2 year olds have a theory based on desire psychology, aka
They assume peoples desires influence their behaviour

Like all interpretations, may be inaccurate
Interpretations may be inaccurate, aka a
False belief
Perner, 1991

4

Theory-theory
Meta-representations theory
Carlson + Moses, 2001

Inhibitory control
Carlson + Moses, 2001
Which skills come first
Executive function of ToM
Executive function
Hughes + Ensor (2007)
What suggests that executive function skills support ToM?
Executive function skills come first
Milligan et al., (2007)
Better language skills are associated with
Better ToM
Meins et la., (2002)
Interactions with others (especially_________) are correlated with greater
Involving mental state language/people older than child
ToM
Influential explanation of ASD is that it involves
ToM impairment
Autism
Using the Sally-Anne Task, only _____ of ASD children passed
20% (compared to 80% of TD)
ToM deficit account cannot explain all symptoms of ASD, e.g. (2)
Sensory symptoms
Repetitive behaviour
ToM cannot fully explain ASD, because a proportion of children with ASD still…
Pass false belief tasks (not a universal deficit)
