Identity - Theory of Mind

12 important questions on Identity - Theory of Mind

What kind of activity constitutes theory of mind?

Any activity that requires having an awareness of someone else's thoughts and intentions and knowing that those thoughts and intentions can be different from your own.

How does Theory of Mind develop?

ToM develops alongside

Biological development - Maturation of brain systems

Cognitive development - Integration of various cognitive skills

Social development - Shaped by cultural & social experiences

Theory of Mind (Biological development) - What are the proposed 2 structures that must develop for TOM?

Amygdala - processes memory and emotion

Temporary parietal cortex  - processes information about external and internal environments and looking for distinctions between those

Theory of Mind (Cognitive Development) - How does TOM develop?

As our understanding of the world becomes more complex, we become aware that other people also have a complex understanding of the world.

Theory of Mind (Social Development) - How does TOM develop? Do social activities rely on TOM?

Social activities rely on theory of mind, but they also help develop a theory of mind.

Every social interaction that we have with another person is an opportunity to learn how people might think and feel differently from us.

Does Theory of Mind change over time? (Months)

Yes.

Early infancy - Interest in others

3 months  - Rudimentary Joint attention

8 months - Intention (desire to act a certain way)

9 months - Gesture (communication, pointing)

12 months - Understanding others’ desires

18 to 24 months - Refined joint attention; imitation; sensitivity to others’ intentions; pretend play

Does Theory of Mind change over time? (Years)

Yes.

3-4 years - Understanding of false beliefs   

5 years - Preliminary interpretative ToM 

6 years - Second order ToM 

9 years - Advanced interpretative ToM, Preliminary understanding of sarcasm, irony

How do siblings affect Theory of Mind development?

The more siblings a child has, the richer that early social environment and the greater the opportunity for developing theory of mind.

Why do 3 year olds show no evidence of false belief understanding but 5 year olds do? What happens between the 2 years? [Social development]

Cultural influences - Contexts provide extent  for predicting likely mental states

Family relationships - Diversity of relationships provide models for diversity of mental states

Sibling constellations - Opportunities to witness separate mental states (role models, conflict, play)

How to measure theory of mind?

False belief tasks - Tasks that test a child’s understanding that other people will act according to their own beliefs, even when the child knows those beliefs are incorrect


Example:
Sally and Anne Task

Smarties task / M&M task

Is age associated with false belief understanding?

Studies show that 3 year olds typically fail false belief tests and 5 year olds typically pass false belief tests

But some evidence that children younger than 3 can demonstrate false belief understanding and there is evidence that ToM continues to develop beyond age 5

Are siblings associated with false belief understanding?

Yes, number of siblings correlates positively with percentage pass rate of false belief tasks

But correlation between number of siblings and number of children passing false belief tasks can be weak. Social relationships might be more important for how children interpret ToM than how they develop ToM

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
