Language and Development Overview

Language and Development

• Language, whether written, spoken, or signed, is crucial for community formation.
• Human ability to communicate became essential as they lived in groups.

Components of Language

• Phonology: The study of the sounds of language.

  • The English language has around 40 speech sounds (phonemes).
  • Children must differentiate language sounds from other noises (e.g., sneezing, coughing).
  • Subtle differences in sounds can change meaning.

• Morphology: The structure of words.

  • Many words are composed of smaller units called morphemes.
  • Each morpheme contributes to the overall meaning.
  • Example: "redesigned" is composed of "re" (again), "design" (verb root), and "ed" (past tense).

• Semantics: The association of meaning with words.

  • Children learn that combinations of sounds (phonemes) represent objects or events.
  • Words can represent entire categories (e.g., animals.)

• Syntax: How words are arranged to form sentences.

  • Sentence structure affects meaning.
  • Example: "John has only three pieces of candy" has a different meaning from "Only John has three pieces of candy."

• Pragmatics: The dependence of language on context and prior knowledge.

  • Language use varies based on the audience and relationship.
  • Example: asking for a seat on a bus.

Language Development

• Babbling: A crucial precursor to language, occurring spontaneously in nearly all children (including deaf children) during the first year of life.

  • Hearing children reach peak babbling between 9 and 12 months old.
  • Deaf children stop babbling shortly after it starts.

• Timeline of Acquisition: Language acquisition is consistent across children.

  • 12-18 months: Children add one word per month.
  • 18 months: A significant increase in vocabulary occurs.
  • 18-20 months: Children start combining words to make basic sentences.
  • Eventually: Vocabulary increases, and longer sentences are formed, possibly causing grammatical errors as the child internalizes grammar rules.

• 2-3 years: Children speak in longer sentences with exponential vocabulary growth. Grammatical errors increase as the child understands more complex grammar rules.

Language Theories

• Observational and Operant Conditioning: These theories explain learning and understanding basic words, but not complex grammar.

• Nativism: This theory, associated with scholars like Noam Chomsky, posits that humans are born with an inherent capacity for language learning. Nativists argue that certain grammatical structures are hardwired into the brain, enabling children to acquire language naturally and efficiently, typically through exposure to their linguistic environment. This innate ability is often contrasted with behaviorist theories, which emphasize learning through reinforcement and imitation. Researchers have proposed the idea of a "universal grammar," suggesting that all human languages share common underlying principles due to this biological predisposition. Thus, while environmental factors influence language exposure, the fundamental aspects of language acquisition are rooted in our genetics.: This theory states people are predisposed to language (a nature-based theory).

  • A critical period for language acquisition exists between infancy and puberty. Training after this period is largely ineffective.
  • The Language Acquisition Device (LAD) is a theoretical construct proposed by linguist Noam Chomsky, which posits that humans are born with an inherent capability to acquire language. This concept suggests that the brain is equipped with a set of grammatical rules and principles, allowing children to decode the complexities of language rapidly and efficiently. The LAD operates by analyzing the linguistic input children receive from their environment, enabling them to generate sentences and understand syntax without explicit instruction. This innate mechanism highlights the distinction between natural language learning and the behaviors emphasized in traditional behaviorist theories, further supporting the idea of a universal grammar shared among diverse languages. The LAD underscores the belief that language acquisition is a unique and biologically driven process. is a theoretical tool for learning language supported by animal studies.
  • LAD has no specific brain region related to it.

• Interactionism is a theoretical framework in sociology and linguistics that emphasizes the importance of social interactions in the development of language and communication skills. This perspective posits that language acquisition is not solely an innate ability, as suggested by theories like the Language Acquisition Device, but is also significantly influenced by the social environment in which a child grows up. Through interactions with caregivers and peers, children learn not only the vocabulary and grammar of their language but also the nuances of social communication, context, and cultural norms. This approach highlights the dynamic interplay between individual cognitive capabilities and the social context, acknowledging that language learning is a collaborative process rather than a purely individual endeavor. Interactionism also explores how language use shapes social identities and relationships within a community.: This theory suggests a combination of nature and nurture in learning language

Influence of Language on Cognition

• Whorfian Hypothesis: Language affects thinking.

Vygotsky's theory of Social Development

• Cognitive development involves social interaction, culture, and language.
• Children have difficulty understanding that others may know something different.
• This understanding is especially important in providing medical care to children.

Children's Understanding of Illness

• Children's understanding of illness varies by age and developmental stage.
• 2-4 years: Phenomenism (objects cause illness)
• 4-7 years: Contagion (illness spread by proximity)
• 7-9 years: Contamination (illness through contact, possibly punishment)
• 9-11 years: Internalisation (illness inside the body; external factors)
• 11-16 years: Physiological (illness due to organ/system malfunction)
• 16+ years: Psychophysiological (psychological factors affect physiology)
