Vygotsky's theory of social development

Social origins of development

• Every function in a child's development appears twice: first on the social level (between people), then on the individual level (inside the child).
• Culture provides the tools of thinking: language, number systems, ways of remembering. Different cultures therefore produce different patterns of thinking and behaving.
• Social interaction with more knowledgeable others in the ZPD drives development; scaffolding supports it.
• Speech: social speech becomes private speech (self-talk that regulates behaviour, such as calming oneself or planning) and then inner speech. This is how children learn to regulate emotions and behaviour.

Applying it to social and emotional development

• Children learn rules of turn-taking, sharing and managing feelings by doing them with adults and peers first.
• Pretend play is a 'zone' where children act beyond their usual level, practising self-control (for example, following the rules of a role).
• Peer collaboration and guided participation in everyday cultural activities (cooking, family work) build social skills.
• Social and emotional learning (SEL) programmes in schools, such as the one in Ashdown and Bernard (2012), teach skills explicitly through guided practice, in line with this idea.

Evaluation

• Strengths: explains cultural variation; supported by research on private speech (more self-talk when tasks are harder); practical application to teaching and SEL.
• Weaknesses: underplays biological maturation and individual temperament; vague about exactly how the social becomes internal, so hard to test objectively; the theory says relatively little about emotion itself.
• Compared with Erikson: both stress the social world, but Erikson proposes fixed age stages with crises, while Vygotsky proposes no fixed stages and stresses culture and language.

Worked example

A 4-year-old mutters 'slowly, slowly' to herself while carrying a full cup. Explain using Vygotsky's theory.

1. She is using **private speech**: speech directed at herself, aloud.
2. It came from social speech (an adult once said it to her).
3. It now regulates her own behaviour and will become silent **inner speech**.

Answer: Private speech regulating behaviour, internalised from social speech.

Check yourself

1. According to Vygotsky, a mental function first appears
   • on the social level, between people
   • inside the child before any interaction
   • only after formal operations
   • through reinforcement
   Show answer

   on the social level, between people. Social first, then individual.

2. Which is an example of a cultural tool in Vygotsky's theory?
   • A reflex
   • A gene
   • Language
   • Object permanence
   Show answer

   Language. Language and number systems are cultural tools.

3. In Vygotsky's theory, private speech helps children to
   • regulate their own behaviour and emotions
   • babble
   • conserve number
   • form a monotropic attachment
   Show answer

   regulate their own behaviour and emotions. Self-talk guides action.

4. Why does Vygotsky see pretend play as important?
   • It has no developmental value
   • It replaces the need for adults
   • It is the stage after formal operations
   • It lets children act beyond their usual level and practise self-control
   Show answer

   It lets children act beyond their usual level and practise self-control. Play creates a ZPD.

5. How does Vygotsky's theory differ from Erikson's?
   • Vygotsky proposes eight crises
   • Vygotsky proposes no fixed age stages and stresses culture and language
   • Erikson ignores social relationships
   • Erikson says development ends in childhood
   Show answer

   Vygotsky proposes no fixed age stages and stresses culture and language. Erikson has fixed stages; Vygotsky does not.

6. Explain one strength of Vygotsky's theory of social development.
   Show answer

   It explains why children in different cultures develop different skills and ways of thinking, because culture supplies the tools and social interactions children learn from.. Culture is the key.
