Q

Desire based theory of mind

Repacholi and Gopnik 1997

A
  • 18m but not 14m understood that the experimenter’s desired food differed from theirs
  • Suggests they understand that desire is a subjective mental state that can differ from person to person

Q

Belief based theory of mind

A
  • Distinction between mind / world
  • Requires the notion that a person has a representation of the world, the contents of which may be quite different from the contents of the world itself
  • Shift from a situation-based to a representation-based understanding of behaviour

Q

Interpreting the findings

A

•3 year old children usually fail FB tasks
•4 year old children usually pass FB tasks
 Traditionally taken as evidence that around this time children ‘acquire’ a theory of mind
•I.e. Radical conceptual shift and stage-like development around 4 years

•But perhaps the FB task underestimates younger children’s ability?

Q

Do we KNOW that 3 year olds don’t have theory of mind

A

•lack of positive evidence doesn’t necessarily mean lack of competence
•Performance limitations masking children’s competence?
•problem with language?
–temporal marking
–test question – “where will maxi look first of all?”
(Siegal & Beattie, 1991)
–story comprehension (Lewis et al. 1994)
•Simplifying the task improves performance but not dramatically – *see ch in Mitchell & Ziegler for summary

The big debate includes
Boosters vs Scoffers
31
Boosters
‘Boosters’ •Early onset view •Early Competence * Posits: * Early competence is masked by performance limitations * task manipulations may enhance performance * 3yr.o. should be able to perform above chance
32
Scoffers
* Delayed onset view * Conceptual change * Posits: 1. performance must change from incorrect to systematically above chance 2. Developmental change on FB tasks reflects genuine conceptual change
33
Wellman Cross and Watson 2001 | Meta analysis of 178 studies
•Support for substantial developmental effect over preschool years: 30mos: 80% incorrect 44mos: 50% correct 56mos: 75% correct Greater than 3.5 years below chance Less than 4 yrs above chance
34
Factors affecting Wellman, Cross & Watson, 2001: | meta-analysis of 178 studies
* Which task variables make a difference? * Type of task/question, nature of protagonist/object irrelevant * Deceptive motive, active participation and salience of mental state improve performance
35
Wellman et al (2001) conclude that their findings are
More in line when the conceptual change (scoffers) account * Although manipulating several variables improved performance, this was the case across all ages rather than just younger children –not selectively unmasking early competence * None of the variable manipulations improved performance of 3yos above chance
36
Callaghan et al 2005 Universality Cross Cultural Comparisons
Despite leading very different lives children in industrialized societies and those in more rural societies show similar developmental shift between 3 and 5 years
37
Factors contributing to Theory of Mind development
1. Role of social experience in aiding understanding of mental states –arises from interactions from other people 2. Biological maturation enables children to express their understanding of mental states – arises from improvement in executive functioning
38
Harris 1999 | Role of experience
* Conversations in general are crucial for exposing children to other people’s perspectives * They provide children with the vocabulary needed to discuss and reflect on mental states
39
Perner, Ruffman, & Leekham, 1994; Ruffman, Perner, Naito, Parkin, & Clements,1998) Role of experience
Children with older siblings show earlier ToM
40
Dunn et al., 1991; Ruffman, Slade, & Crowe, 2002) Role of experience:
Children whose parents talk about mental states more understand false belief earlier than other children
41
Peterson & Siegel, 1995 | Role of experience:
Deaf children of hearing parents show a developmental lag on FB taks Peterson & Siegal, 1999) •In contrast, deaf children of signing parents are comparable with hearing children
42
Theory of mind scale | Wellman and Liu 2004
* Diverse Desires: people can have different desires for the same thing * Diverse Beliefs: people can have different beliefs about the same situation * Knowledge-access: something can be true, but someone might not know that * False Belief: something can be true, but someone might falsely believe something different
43
Wellman and Liu 2004 | Diverse desires
people can have different desires for the same thing
44
Wellman and Liu 2004 | Diverse beliefs
people can have different beliefs about the same situation
45
Wellman and Liu 2004 | Knowledge access
something can be true, but someone might not know that
46
False belief | Wellman and Liu 2004
something can be true, but someone might falsely believe something different
47
Wellman et al 2006 | Cross cultural differences
•Children in Western countries: DD>DB>KA>FB>HE •Chinese and Iranian children: DD>KA>DB>FB>HE Thought to be related to differences in cultural values: collectivist vs. individualism
48
The role of executive functioning
•Children’s failures on ToM tasks may stem not from pure conceptual limitations but rather from problems translating conceptual knowledge into successful action  critical role of executive functions in ability to pass ToM tasks

From problems translating conceptual knowledge into successful action.
50
Executive functions
A set of domain-general cognitive abilities that help us to control and guide our attention and behaviour E.g. Using card machine
51
Executive functions | Inhibition.
•Ignoring distracting information or suppressing unwanted responses •Real life –Stop yourself reaching for that bar of chocolate!
52
Executive functions | Cognitive flexibility
•Responding to the same thing in different ways depending on the context •Real life –Multiple passwords/pin numbers
53
Executive functions | Working memory
* Holding important information or your ‘goal’ in mind. * Manipulating information in your head * Real life * Mental shopping list * Mental arithmetic * In the lab * Digit span * Spatial span
54
The role of executive function in false belief tasks
•EF skills are clearly necessary for successful performance on false belief tasks. E.g.: 1. cognitive inhibition to disengage from a salient real-world situation to attend to an intangible abstract representation 2. response inhibition to inhibit a prepotent or habitual way of responding (i.e., pointing to the ‘‘true’’ location of the object) 3. working memory to indicate the correct answer while holding in mind two different and conflicting representations
55
The frontal lobes of the brain are very important for. .. | Diamond and Taylor 1996
Executive functions •They take a long time to develop •Important developments in Inhibitory control (IC) take place in the first 6 years of life, with marked improvement between age 3 and 6
56
Carlson and Moses2001 Sabbagh et al 2007 The role of EF in false belief tasks
Evidence of strong positive correlation between children’s inhibitory control (e.g. on Bear/Dragon task) and FB performance •Suggests that: development in IC and ToM may be related •IC may be a crucial enabling factor for ToM development, possibly affecting both the emergence and expression of mental state knowledge.

Children with explicit and implicit judgement
Above task requires child to make an explicit judgement about another's mental state Do children demonstrate earlier, implicit understanding of belief?
60
Levels of knowledge
•Explicit knowledge –knowledge easily accessible to the child –Measure via elicited response, e.g. verbal answer to a question •Implicit knowledge –Knowledge the child is unaware of –Measure via spontaneous response, e.g.: •Emotional response (Moll, Kane & McGowan, 2016) •Anticipatory looking (Clements & Perner, 1994) •Violation of expectancy (Onishi & Baillargeon, 2005)
61
Explicit knowledge
–knowledge easily accessible to the child | –Measure via elicited response, e.g. verbal answer to a question
62
Implicit knowledge
–Knowledge the child is unaware of –Measure via spontaneous response, e.g.: •Emotional response (Moll, Kane & McGowan, 2016) •Anticipatory looking (Clements & Perner, 1994) •Violation of expectancy (Onishi & Baillargeon, 2005)
63
Implicit understanding of FB | Moll et al 2016
* Investigated children’s facial expressions as indices of their belief understanding * Predicted that if 3 yos are aware of the conflict between a person’s belief and reality, they will show signs of suspense (e.g. lip biting and brow furrowing) when observing an actor about to act on basis of their false belief
64
Implicit understanding of FB Moll et al 2016 results
Results: •Found greater instances of expressed tension in the false belief cf. true belief condition •Suggests 3 yos were aware of another’s false belief and recognised the affective consequences of the false belief •In contrast, children’s performance on a classic FB task was poor and unrelated to the amount of expressions they displayed while watching the FB videos  suggests expressions are independent from and emerge prior to explicit knowledge of false beliefs.
65
Implicit understanding of FB Clements and Perner 1995 Aim and Method
* Aim: to get evidence for a period of implicit understanding of FB that precedes the onset of explicit understanding * Method: Tested 44 children aged 2y5m – 4y6m on ‘unexpected transfer task’ –Implicit measure – anticipatory looking –Explicit measure – standard verbal response
66
Younger kids show
Non verbal Fb understanding But these tasks may draw on different levels of knowledge (implicit vs explicit)
67
Children may sometimes overapply ...
Theory of mind rules
68
Adults are not as good at
Mentalising as we might assume
69
Sodian and Wimmer 1987 Ruffman 1996 Over application of rules
``` •cannot see, but •children aged <6yrs: “it was an m&m” •would someone else (with the same info) know it was an m&m? •“No” – show inference neglect ``` Over application of not seeing = not knowing the rule? Knowledge through inference without awareness
70
Evidence for access rule | Wimmer et al 1988
–3-4 yr olds attribute knowledge to observer who sees or is told content of a container and –ignorance to observer with neither informational access
71
Evidence for No Access Rule ( over application) | Ruffman 1996
–Attribute ignorance of observer who has not seen/being told even if the observer has some other source of information about event –Ignore non-visual sources of info (logical inference)
72
Theory of mind rules | 3
Theory - Theory = Gopnik and Wellman 1992 Access rule = Wimmer et al 1988 No Access Rule (Overapplication) = Ruffman 1996
73
Theory - Theory (TOM Rule) Gopnik and Wellman 1992
children’s understanding of mind resembles a scientific theory –Form and revise coherent set of rules –Failure due to incorrect or misapplied rules •evidence that children: –initially understand the relationship between seeing and knowing and rigidly follow: seeing/being told = knowing (Access Rule), –then overextend rule to form the rule that: not seeing or not being told = ignorance (No-Access Rule) –Overapplication? I walk -> I walk-ed, I run -> I run-ed
74
Heyes 2014 comment
argues that infants may represent the events in these experiments as “colours, shapes and movements rather than as actions on objects by agents”
75
Clements and Perner 1994 experiment | Implicit understanding of FB
Note: control condition – true belief task Anticipation prompt: “Sam is waking up. He’s going to get his cheese. I wonder where he’s going to look” <2 sec pause – record child’s eye gaze> = Indirect Measure Test Question: “Which box will he open first?” = Direct Measure
76
Implicit understanding of FB Clements and Perner 1994 Results
* 86% children over 2y11m showed looking pattern indicative of FB understanding * Only 1 child under 2y11m
77
Wiesmann et al 2017 | Dissociation of implicit - explicit understanding of belief
* 3yr olds looked to correct location even though gave incorrect answer! * Large gap between implicit and explicit understanding from 2y11m  Data suggest that children develop an implicit or unconscious understanding of false belief at an earlier age than they develop an explicit or conscious understanding
78
Southgate, Senju and Csibra (2007) Action Anticipation through Attribution of False Belief by Two-Year-Olds
•Used anticipatory looking •Earlier FB understanding than Clements & Perner (1994) may be due to methodological differences e.g.: –Non-verbal prompt –Toy is removed from the scene to avoid “reality bias”
79
Surian Caldi Sperber 2007 | Supporting evidence
Evidence of infants’ FB understanding using an active behavioural measure rather than looking time, see Buttlemann et al. (2009)
80
Onishi & Baillargeon (2005) | Even earlier false belief understanding in infancy?
•Used a totally nonverbal task to test for implicit FB understanding in 15 month old infants •Violation of expectancy method Summary: significantly longer looking when expectation violated, i.e., actor’s action inconsistent with actor’s belief: - when actor reaches in wrong box when has true belief belief, or -reaches in right box, when actually has false belief * suggests infants expect people to search for objects consistent with their beliefs about the object location, not where the objects are in reality * Evidence that ToM is inborn?
81
Looking time studies with infants: | Violation-of-expectancy method
•Familiarise infant to an event •Present test behaviour that is either: –Consistent –Inconsistent With the prior event •If infant looks longer at inconsistent event taken as evidence that they are surprised •Indicates some level of knowledge about what should happen
82
According to the 'early onset account' results with infants provide evidence for early
FB understanding when using spontaneous-response tasks •Suggests ToM development is gradual •Pre-schoolers’ difficulty with traditional elicited response tasks stem primarily from immature executive function processes - inability to inhibit responding on the basis of own perspective •This is supported by evidence of correlations between inhibitory control measures and false belief
