Introduction: Language development is a crucial aspect of cognitive development in children. It involves acquiring the ability to understand, produce, and use language effectively for communication. In this lecture, we’ll explore the stages of language development, key theories, and factors influencing communication skills in children.

Key Concepts of Language Development:

  1. Stages of Language Development:

    • Prelinguistic Stage (Birth to 12 months):
      • Infants communicate through crying, cooing, and babbling.
      • Recognize familiar voices and sounds, and begin to understand simple words.
    • Babbling Stage (4 to 12 months):
      • Infants produce repetitive consonant-vowel combinations, such as “ba-ba” or “da-da.”
      • Begin to mimic the intonation and rhythm of adult speech.
    • One-Word Stage (12 to 18 months):
      • Children start using single words to represent whole sentences, known as holophrases (e.g., “milk” to mean “I want milk”).
      • Vocabulary growth accelerates, with children understanding more words than they can produce.
    • Two-Word Stage (18 to 24 months):
      • Children begin to combine two words to form simple sentences (e.g., “more juice” or “big truck”).
      • Grammar starts to emerge, with a focus on key content words.
    • Telegraphic Speech Stage (24 to 30 months):
      • Children’s sentences become longer and more complex, resembling telegrams with key words and missing less important ones (e.g., “want cookie” or “mommy go work”).
      • Rapid expansion of vocabulary and grammatical skills.
    • Later Multiword Stage (30 months and beyond):
      • Children use complete sentences with more sophisticated grammar.
      • Develop the ability to engage in conversations, ask questions, and tell stories.
  2. Theories of Language Development:

    • Nativist Theory (Chomsky):
      • Proposed by Noam Chomsky, this theory suggests that children are born with an innate ability to learn language, known as the Language Acquisition Device (LAD).
      • Emphasizes the universality of language development and the presence of universal grammar across languages.
    • Learning Theory (Skinner):
      • B.F. Skinner’s behaviorist approach posits that language is learned through reinforcement and imitation.
      • Children acquire language by mimicking caregivers and receiving positive reinforcement for correct language use.
    • Interactionist Theory (Vygotsky):
      • Lev Vygotsky’s theory highlights the role of social interaction in language development.
      • Children learn language through interactions with more knowledgeable others, emphasizing the importance of the social and cultural context.
  3. Factors Influencing Language Development:

    • Biological Factors: Genetic predisposition and brain development play a crucial role in language acquisition. Areas such as Broca’s and Wernicke’s areas are vital for speech production and comprehension.
    • Environmental Factors: The language environment, including the amount and quality of verbal interactions with caregivers, significantly influences language development.
    • Social Interaction: Engaging in conversations, reading books, and participating in interactive activities enhance language skills.
    • Cognitive Development: Language development is closely linked to overall cognitive development, including memory, attention, and problem-solving skills.

Application to Child Development:

  • Recognizing the stages of language development helps caregivers and educators provide appropriate support and stimulation to promote effective communication skills.
  • Understanding different theories of language development informs strategies for fostering language acquisition in various contexts.


  1. At what stage do children typically start combining two words to form simple sentences? a) Prelinguistic stage b) One-word stage c) Two-word stage d) Telegraphic speech stage

Answer: c) Two-word stage

Takeaway Assignment: Observe a child interacting with their caregiver. Note the stages of language development they demonstrate and the types of communication skills they use. Reflect on how the caregiver supports the child’s language development.

Relevant Scenario: Consider a preschool classroom where teachers use interactive storytelling and singing to enhance children’s language skills. This scenario illustrates the importance of rich language environments and social interactions in promoting language development.

Case Study: Explore a case study of a child with delayed language development. Analyze potential biological, environmental, and social factors contributing to the delay and discuss interventions to support the child’s language acquisition.


  • A toddler in the two-word stage might say “more cookie” to express a desire for another cookie.
  • An example of Vygotsky’s interactionist theory in practice is a parent engaging in a back-and-forth conversation with their child, providing scaffolding to help the child learn new words and concepts.

Final Topic Summary: In this lecture, we examined the stages of language development, from prelinguistic communication to complex sentence formation. We explored key theories, including nativist, learning, and interactionist perspectives, and identified factors influencing language development. Understanding these concepts is essential for supporting children’s language acquisition and communication skills.
