What is “Theory of Mind”?• “Folk psychology”, “Perspective-taking”, “Social cognition”• Essential for everyday social interaction and communication
• False belief tasks as a paradigm case• (e.g., Wimmer & Perner, 1983)
– These tasks ensure that participant must judge from other person’s point of view

What is “Theory of Mind”?• “Folk psychology”, “Perspective-taking”, “Social cognition”• Essential for everyday social interaction and communication
• False belief tasks as a paradigm case• (e.g., Wimmer & Perner, 1983)
– These tasks ensure that participant must judge from other person’s point of view
• Significant developments from infancy to early childhood
• Disproportionately impaired in autism and several other genetic and psychiatric disorders

Overview
• Part 1– Evidence (from adults) that mindreading
• Often requires cognitive control• May recruit specialised neural systems• May sometimes operate efficiently and automatically
• Part 2– How do these characteristics arise?
![Page 7: Controlled and automatic mindreading in children and adults](https://reader035.fdocuments.net/reader035/viewer/2022062520/56816331550346895dd3b482/html5/thumbnails/7.jpg)
Evidence that mindreading is a flexible but demanding ability
• In Adults....• Impaired executive processes can lead to severe egocentrism
– (e.g., Samson, Apperly, Kathirgamanathan & Humphreys, 2005)
• Belief reasoning requires cognitive control– (e.g., Bull, Philips & Conway, 2007)
• Belief inferences are not made automatically – (Apperly, Samson, Riggs, Simpson & Chiavarino, 2006; Back & Apperly, 2010)
• Belief inferences are not used automatically– (e.g., Keysar, Lin & Barr, 2003; Apperly et al., 2010)
• Holding false beliefs briefly in mind has a measurable processing cost
– (Apperly, Back et al., 2008)
• Recursion (e.g., beliefs about beliefs) remains challenging– E.g., Mckinnon & Moscovitch (2007)
• And this converges with evidence from children…• .

• Recursion (e.g., beliefs about beliefs) remains challenging– E.g., Mckinnon & Moscovitch (2007)
• And this converges with evidence from children…
• Mindreading seems to depend on processes for attention, working memory and executive control
• Recruitment reflects functional components of mindreading• .

Specialised neural systems for Mindreading?(Saxe & Kanwisher, 2003......)
False belief (FB) sample storyJohn told Emily that he had a Porsche.Actually, his car is a Ford. Emilydoesn’t know anything about carsthough, so she believed John.—When Emily sees John’s car shethinks it is aporsche ford
False photograph (FP) sample storyA photograph was taken of an apple hangingon a tree branch. The film took half an hour todevelop. In the meantime, a strongwind blew the apple to the ground.—The developed photograph shows the apple on theground branch

R-TPJ shows greatest specificity for reasoning about mental states. Contrast with mPFC, which also shows activity for thinking about body states, internal sensations and personal characteristics.

Evidence that mindreading is an efficient but inflexible processes?
• Can all mindreading really be so demanding?• Two systems for mindreading? (e.g., Apperly &
Butterfill, 2009, Psych. Rev.)
![Page 19: Controlled and automatic mindreading in children and adults](https://reader035.fdocuments.net/reader035/viewer/2022062520/56816331550346895dd3b482/html5/thumbnails/19.jpg)
Evidence that mindreading is an efficient but inflexible processes?
• Can all mindreading really be so demanding?• Two systems for mindreading? (e.g., Apperly &
Butterfill, 2009, Psych. Rev.)
• Evidence of involuntary inference of:• Simple visual perspective (Samson et al., 2010)• Agent’s spatial frame of reference (Zwickell, 2011)• Agent’s “false belief” (Kovacs et al., 2010)
• Sometimes without explicit awareness• Schneider et al. (2011)
• Without need for “executive control”• Qureshi et al. (2010)
• This pattern converges with evidence of mindreading in infants….

Evidence for automatisation?Surtees & Apperly (2012) Child Development

120 children aged 6-10 and adults
Automatisation: Predict younger children to suffer less interference for self judgements.
Original automaticity:Predict equivalent interference at all ages.

Neural specialisation through development
• E.g., Reading development
• correlation with children’s reading skill– Yellow = +ve – Blue = -ve
• Neural specialisation emerges• Unlikely to be determined by an
evolved programmeTurkeltaub et al. 2003

• Part 1– Evidence that mindreading
• Often requires cognitive control• May sometimes operate efficiently and
automatically• May recruit specialised neural systems
• Part 2– Development must be explained– Development constrains theories of the
