Cognitive development occurs through social interaction and internalization of socially shared processes. Children first learn skills and concepts through interaction with others, then internalize them to perform independently. For example, a child learns to point through social interactions with caregivers before understanding it as a means of communication. Similarly, a child learns to tie shoes through verbal guidance from an adult before being able to do it alone. Vygotsky's theory of the zone of proximal development also illustrates how children can perform higher-level tasks with assistance from others before mastery alone. Language plays a key role in cognitive development, first appearing between people and then within the individual through private speech that later becomes inner speech.
![Vygotsky on Language and Thought
Thought and speech have different roots. The two
functions develop along different lines and
independently of each other. (p. 41)
At a certain point these lines meet, whereupon
thought becomes verbal and speech rational. (p.44)

- 1. COGNITIVE DEVELOPMENT OCCURS IN SOCIAL INTERACTION The Internalization of Socially Shared Processes Every psychological function occurs twice, first at the “intermental” level (between people who are involved in social interaction), and later at the “intramental” level (within the individual)
- 2. An Example of Internalization of Socially Shared Processes The development of pointing: • infant unsuccessfully reaches for desired object • adult interprets action as an attempt to draw attention to object • meaning of instrumental attempt changed to an attempt to communicate • infant links reaching action to social situation, comes to understand movement as directed at another person • social meaning of action is internalized, becoming a true gesture
- 3. An Example of Internalization of Socially Shared Processes A child learning to tie her shoes: • at first, an adult assists the child, providing verbal guidance (e.g., “now make a loop, and bring the other lace around it …”) • with time, the child internalizes the sequence of steps so that she can control her own actions without adult assistance • the child may “hear” the adult’s instructions in her “mind’s ear,” but she no longer needs the adult to provide external support for her performance
- 4. COGNITIVE DEVELOPMENT OCCURS IN SOCIAL INTERACTION The Zone of Proximal Development “the distance between what a child can do independently, and what a child can do in interaction with an adult or a more advanced peer” Moms Teachers Siblings
- 5. Zone of Proximal Development – 2 Children Unaided Aided Unaided Aided Higher Lower Higher Lower Child A Child B % Correct
- 6. An Example of Social Scaffolding Scene: Mom is helping child construct a puzzle. They have a model that they can refer to. The child tries to place green pieces where they do not belong. Mom: Did we find any green up here? (points to model) Child: (looks at model) This one. (points to incorrect place in the model) Mom: I think maybe that’s a leftover. Do you think so? Child: (nods) Mom: Maybe we don’t need the green one, cause there isn’t any green one up there, is there. Remember? Child: (looks at pieces pile, puts green pieces back, chooses
- 7. Key Factors in Sensitive Adult-Child Interaction tailor support to child’s level of skill development (cognitive readiness) - one step ahead is best monitor child’s attention to intervene at appropriate time e.g., mothers who label objects for their toddlers by following where the child focuses his/her attention
- 8. Key Factors in Sensitive Adult-Child Interaction continued prompt metacognitive awareness - outline goals of the task - discuss strategies for meeting goals - involve child in making decisions
- 9. Peer Collaboration - Does it Work? helps to motivate child to try difficult tasks provides opportunities to imitate and learn each other’s skills opportunities to explain, put their knowledge into words, enhances understanding Answer: Sometimes it Does, Sometimes it Doesn’t

- 11. Vygotsky’s basic idea of language and thought Language Thought ~ 2 years
- 12. Language as a Psychological Tool Private Speech Children talking to themselves as they play, explore, and solve problems. An intermediate phase in which language guides thought and behavior, but it must be overt. Eventually private speech is internalized and becomes inner speech.
- 14. Pre-operational Period: Egocentric Speech Mary: They wiggle sideways when they kiss. John: (vaguely) What? Mary: My bunny slippers. They are brown and red and sort of yellow and white. John: I have a piece of sugar in red pieces of paper. I’m gonna eat it and maybe its for a horse. Mary: We bought them. My mom did. We couldn’t find the old ones. They were in the trunk. John: Can’t eat the piece of sugar, not unless you take the paper off. Mary: And we found Mother Lamb. Oh, she was in Pough- keepsie in the trunk in the house in the woods. John: Do you like sugar? I do, and so do horses.
- 15. Pre-operational Period: Social Speech Adam: If I grow up my voice will change and when you grow up your voice will change. My Mom told me. Did your Mommy tell you? Jenny: No, your Mommy’s wrong. My voice, I don’t want it to change. Adam: Oh, well, we’ll stay little, right? Jenny: What? Adam: We’ll stay little. Jenny: No, I don’t want to. I want my voice to change. I don’t care if it changes. Adam: I care.
- 16. Key Findings in Language Guided Thought Preschool Years children produce more private speech on more challenging tasks children’s private speech declines with age (“goes underground”) private speech is not egocentric speech talking aloud is not a failure to engage in role taking

- 18. BRUNER’S MODES OF REPRESENTATION Enactive Representation - using actions to represent information, dominant mode of representation in the sensori-motor period (0 to 2 yrs), “thought is action” Iconic Representation - using visualization to represent information, dominant mode of representation during the preschool years, Piaget’s conservation tasks are good examples Symbolic Representation - using language or other symbols to represent information, middle childhood and beyond
- 19. BRUNER’S CLASSIC SCREENING STUDY Participants: 5 to 8 year old children who clearly failed the conservation of liquid substance task. Step 1: Screen is placed in front of the beakers before the liquid is poured.
- 20. BRUNER’S CLASSIC SCREENING STUDY Step 2: Blue liquid is poured from one of the tall beakers to the wide beaker. Step 3: Child is asked whether the liquid is still the same amount. Results: When children do not have the misleading visual information, they say “It’s the same, you only poured it”
