Introduction

            Theory
of Mind (ToM) is the explicit understanding of human behaviour is directed by
mental states of belief, intention, memory, and desire (Peterson, Wellman, & Slaughter, 2012). This is called as theory, because it
is used to make predictions about the behaviour of others and it is not
directly observable (Premack & Woodruff, 1978) . This is very
crucial for human beings to be able to understand each other and to be able to
predict other people’s behaviour, because of that, theory of mind (ToM) have
excited the attention of researchers for more than 30 years (Yott & Poulin-Dubois, 2016). There are
different mental states of theory of mind, however the false belief task is
seen as the litmus test for it (Poulin-Dubois & Yott, 2017).

            As
theory of mind concept, false belief can be assessed as people do things based
on what they think, even if they are mistaken (Slaughter, 2015). In traditional
testing of this task, children get a story where the person in the story misses
information, but children know. So the person in the story has false belief.
After that, children are asked about the belief of person in the story with questions
such as: what the person thinks or where this person will look for an object to
get explicit response (Grosse Wiesmann, Friederici, Singer, & Steinbeis,
2017).  A lot of studies, which are done only this
task, showed that children pass that task after 4 years old; before four years
old, children fail in that task (Gopnik & Slaughter, 1991; Pellicano & Rhodes,
2003; Wellman, Cross, & Watson, 2001). However, newly
done studies showed that there is an important developmental change from age of
3 to 4; while at age of 3 children fail at explicit false belief task, they can
pass implicit false belief task (Grosse Wiesmann et al., 2017).

            Theory
of Mind (ToM) concept is very important that has studied for years. However; findings
of many studies arouse theory of mind researchers’ curiosity and lead them to
focus on mostly theory of mind development in infancy (Heyes, 2014; Slaughter, 2015).  In this proposal, development of understanding
of others’ mind in infancy and; comparisons of typically developing infants and
atypically developing infants in terms of false belief understanding is taken
into consideration.

 

Literature Review

Theory
of mind in infants

            With
these new research findings, many studies have focused on development of theory
of mind in infancy. Poulin-Dubois and Yott (2017) stated in their paper that
the traditional knowledge about development of theory of mind after age 4 was
shaken with the study of Clements and Perner’s in 1994. They found that eye
movements of children at age of 2 years 11 months and older indicated that they
can understand the false belief. With these results, a lot of researchers began
to focus on theory of mind concept from age 2 to infancy.

False
task understanding of theory of mind in typically developing infants

            After
Clement and Perner’s (1994) results, studies began to take into consideration
theory of mind testing in infancy term. Different mental states of theory of
mind was taken into consideration by researchers like early reasoning about
desires among 14 and 18 month old infant (Repacholi & Gopnik, 1997); imitation of
intentional actions among 14 and 18 month (Olineck & Poulin-Dubois, 2007); psychological
reasoning  in 18-month-old infant (Song, Onishi, Baillargeon, & Fisher, 2008). These studies
showed that even though infants could not explain verbally, they were showing
different attitudes during testing of different mental states. In addition to
these studies, because false task understanding is seen as litmus test of
theory of mind (Poulin-Dubois & Yott, 2017), to examine
false belief  from infants’ perspective
will be more helpful to understand this developmental process. In this research
proposal, false belief understanding of infants is studied.

            First
of all, because infants cannot talk, researchers examined the infants looking
behaviour thorough using some paradigms which helps to understand their false
belief understanding.  In 2005 Onishi and
Baillargeon developed a novel nonverbal task to examine15-month-old infants’
ability. In their task, they wanted infants to guess an actors’ behaviour on
the true or false belief about a toy’s hiding place. Findings of that study
showed that infants use mental state to predict others’ behaviour.  Surian, Caldi and Sperber (2007) assessed
infants looking by showing them animations and they stated the view that
infants have an incipient meta representational ability, which provides them to
attribute beliefs to agents. He et al. (2011) used violation of expectation
change-of-location and unexpected- content tasks to see false belief understanding
in 2,5-years-old. They also supported the false belief understanding in
toddlers.

            Even
though there are significant behaviour change in infants, while their implicit
false belief understanding is testing; there is a hot debate among researchers
about whether these studies really give information about false belief
understanding of infant or it is just a part of cognitive development in
infancy (Slaughter, 2015). In the studies,
different age groups and different ways were used to clarify this issue. For
instance, Kovacs,Teglas and Endress (2017) took 7-month-old infants (which are
younger than other studies) as participants to their studies. They also found
that 7-month-old age infant took into consideration of other people’s belief.  Yott and Poulin-Dubois (2012) used behavioural
rules for 18 month-old-infants; Buttelmann, Carpenter and Tomasello (2009 )used
helping behaviour paradigm for 18-month-old infants;Southgate et. al (2010)
examined infants’ tracking the status of a communicator’s epistemic state;
Scoot, Baillargeon, Song and Leslie (2010) showed a search paradigm to 18-month
old infants. In 2007, Southgate, Senju and Csibra measured infants’ looking
behviour by using eye tracker. They examined action anticipation of 2 year-old
infants. In all these studies, even situations and methods are different,
infants faced up a false belief testing. Findings of all studies showed that
infants look differently or attribute differently, when actor when the actor
attributed by basing on a false belief.

            As
a result, after the awareness of children can understand false belief task
before age 4, many research were done on the development of false belief
understanding of typically developing infants. Actually, the studies that are
mentioned above include typically developing children as participants. In these
studies, different paradigms and different methods were used while testing
false belief understanding in infancy term. Studies’ results investigated that infants
understand false belief of agents.

False
task understanding of theory of mind in atypically developing infants

            Most
of the studies that are mentioned above were done to assess false belief
understanding of typically developing infants. When the literature was
reviewed, it was seen that even there are studies on false belief task of
atypically developing children (Surian & Leslie, 1999); according to
our knowledge, there is not any study that specifically focus on false belief
understanding of atypically developing infants (Kampis, Fogd, & Kovács, 2017).

            When
the literature is reviewed, it was observed that in 1999 Surian and Leslie
compared the competence and performance of autistics and normal 3-year-old
children in terms of competence and performance in false belief understanding. They
used a standard prediction of action task (Sally/Anne story). In this study,
normally developing 3 years old children were able to understand the protagonist’s
false belief. Autistics children attended the 3,5-year-old level performance in
this study and they failed standard prediction task. Even this study included 3
and 3,5 years old children, it compared the false belief understanding among
typically and atypically developing children. In another study also theory of
mind abilities of young siblings of children were studied. Participants were 24
siblings of children with autism and 24 siblings of typically developing children
at age of 4.6. There was not any significant difference between groups;
however, differences were found within group results between Tom ability and receptive
language.  

            In
the literature, it could not be found a(Clements & Perner, 1994) study about
false belief understanding among atypically developing infants. However, a
study was found which compares typically developing infants and atypically
developing infants in terms of gaze following, not false belief understanding (Thorup, Nyström, Gredebäck, Bölte, & Falck-Ytter,
2016).  They used eye tracking to assess gaze
following. They found that infants at familial risk for ASD followed gaze less
likely when adult’s eyes were giving directional information than when both
eyes and head of the adult were giving information. Actually, that study gave
knowledge about there is a statistically significant different looking behaviour
between typically and atypically developing infants.

            As
a result, here is not any study related with comparisons of typically and
atypically developing infants in terms of false belief understanding. Studies
that were done among 3 or 4 years found differences between groups and some of
them found in within group differences. An also one study that was done with
infants showed that gaze following of the infants was different for both
groups.

 

 

 

Comparisons
of typically developing infants and atypically developing infants in terms of
false belief understanding

            Theory
of mind (ToM) is a core system in people’s social cognition (Poulin-Dubois & Yott, 2017).  Problems in theory of mind can be symptom of
atypically development, which is known as a core deficit of autism (Shaked, Gamliel, & Yirmiya, 2006).  Early prediction of this deficit make easier
to early intervention. Some studies discovered that implicit false belief
understanding of that theory can be gained from before age 3 to 7 month old (Buttelmann, Carpenter, & Tomasello, 2009;
Clements & Perner, 1994; He, Bolz, & Baillargeon, 2011; Kristine, 2005;
Melinda, Téglás, & Endress, 2017; Sarret & Rommelfanger, 2015;
Southgate, Chevallier, & Csibra, 2010; Surian & Leslie, 1999; Yott
& Poulin-Dubois, 2012, 2016).  However, if it is any deficit in gaining that
ability in infancy can give information about later development.

            Even
a lot of studies demonstrated that infant could understand false belief of others;
there is still hot debate about whether these findings showing the reality of
infants’ understanding of others’ mind (Poulin-Dubois & Yott, 2017; Slaughter, 2015).  Assessment of infants’ false belief
understanding bases on limited, nonverbal facts and these restricted facts cause
these debates (De Bruin & Newen, 2012; Grosse Wiesmann et al.,
2017; Scott, Richman, & Baillargeon, 2015).  Implicit understanding

occurs in the brain of infants, it
is really based on restricted facts. However one of the best ways to clarify
these doubts will compare typically and atypically developing infants in terms
of false belief understanding, which has never done before.  As mentioned above, deficits in understanding
others is core symptom of autism and it gives information about social
cognition of people. Comparisons of typically and atypically developing
infants’ false belief understanding help to get more knowledge about
understanding of others in infancy.  In
the lights of all these findings and literature, the purpose of this research
is compare false belief understanding of typically and atypically developing
infants to get more information about their social cognition.

Method

Participants

            Participants
of the study will be a total of one hundred 9-month-old infants. Fifty infants
will be high-risk infants (HR group) who have at least one older sibling with an
autism spectrum disorder (ASD). Other fifty infants will be infants who have
low-risk. Low-risk infants (LR group) are infants who do not have any person
with ASD in their family history or at least one typically developing older
sibling.

            Participants
will be taken from Child Development Unit of University of Kent in Canterbury,
England. 6-9 and 12-month-old both typically and atypically developing infants
come to that unit for infant testing. These infants can be included to this
study.

            Before
the study is applied to infants, parents will be informed about study and all
ethical issues related with study’s process and confidentiality. A consent form
will be taken from parents. After permission is taken by parents, infants will
be included.

             To recruit more infants announcements will be
presented in study’s website and university’s website. In addition to that,
schools, special working places related with autism spectrum disorder and
clinical centres will be contacted to reach these parents. Participants’ older sibling
with ASD has to be diagnosed as formally by a trained person. Diagnostic
criteria must be based on American Psychiatric Association (2000) and World Health Organization
(1992).

            An
information form will be given to parents. In this form, information about socioeconomic
level of the family (by looking at family income), education level of parents,
developmental history of the infants will be taken. The questions related with
developmental history of infants will be about whether they have any
developmental disorder, whether they have any impairments and whether they get
any medical interventions. With this information, infants who have same
characteristics will be included in this study.

Materials

            The
materials that were used by Yott and Poulin-Dubois (2016) will be used in this
study. They used a stage-like apparatus (107 cm x 61 cm x 211 cm). There is a
window (86 cm x 91 cm) in which the experimenter comes up. The window is far
from 80 cm from the bottom of the front panel. There is a flat surface on the
window. On the top of the surface there is a small place for a digital camera
to record looking behaviour of infants. The infants will observe experimenter
approximately from 110 cm from display. Infants can observe on a high chair or on
their parent’s lap. During the experiments, all parents are requested to be
silent. There is a white curtain to cover the window. It is used by the
experimenter. During testing, infants’ looking behaviours are coded live by a
second experimenter.

Belief
tasks materials

            Yott
and Poulin-Dubois (2016) presented both a red cup or yellow duck for belief
task. In this study, the read cup will be used. The red cup (7.5 in diameter,
10.5 cm high), a yellow box and a green box (14 cm x 14 cm x 14 cm) are
materials of that task. There is an opening side of the each box on the cup
side. It was covered with a fabric fringe. Each box has a rectangular opening
underneath. That opening place lets the experimenter to use to change place of
the cup from one box to another. This is done thorough a magnet that is put
under the cup and under the stage.

 Design and Procedure

            A
room of the Child Development Unit of University of Kent will be designed

Measures
of false belief understanding

            In
this study, to measure false belief understanding, Yott and Poulin-Dubois’
(2016) belief tasks will be used. They adapted the belief tasks from Onishi and
Baillargeon’s (2005) study. In this adaptation they measured both true and
false tasks non-verbally. These tasks are based on violation of expectation
paradigm. Belief tasks include three familiarization trials, and these trials
are followed by a false-belief induction trial and false-belief test trial and
then true-belief induction trial followed by a true-belief test trial. Before
the trial begins, the curtain is raised and after the trial finished the curtain
is lowered. To get attention of infants an attention sound is given at the
beginning and end of each trial.
