Questions and Answers

  • Which of the following best describes the relationship between interaction and input in language acquisition?

  • Interaction enhances the quality and relevance of input, making it more comprehensible. (correct)
  • Interaction is irrelevant to input as children primarily learn through passive listening.
  • Interaction hinders input processing by creating a distracting environment.
  • Interaction is only useful for social development, not for linguistic development.
  • What is a key characteristic that distinguishes child-directed speech (CDS) from adult-directed speech?

  • CDS often involves simplified vocabulary and exaggerated intonation. (correct)

    Study Notes

    Language Input

    • Language input includes child-directed speech (CDS).
    • CDS is the register used by parents and others to communicate with young children.
    • Input involves the forms of language children hear.
    • Interaction refers to how language forms are used in adult-child discourse.
    • Speech from adults constitutes high-quality input.
    • Parents and caregivers modify their speech when interacting with children.
    • Conversations between adults and children are often about the here and now, focusing on concrete concepts.
    • Common conversation topics include family members, animals, parts of the body, food, and clothing.

    Roadmap

    • Child-directed speech
    • Interaction and input

    Linguistic Input

    • Parents and caregivers adapt their speech when interacting with children.
    • Speech from adults serves as quality input for children.

    Child Directed Speech (CDS)

    • CDS is a register used by parents and others to communicate with young children.
    • Input is the language forms children hear.
    • Interaction is the way language forms are used in adult-child discourse.
    • Babies and others use certain types of language, such as baby talk, motherese, and nursery talk.

    Characteristics of CDS

    • CDS involves exaggerated intonation and changes in pitch.
    • CDS uses longer pauses and slower speech.
    • CDS includes repetition.
    • Changes occur at different levels, including phonology and phonetics, morphology and syntax, and vocabulary.

    Phonology/Phonetics & CDS

    • Phonological changes and exaggerations occur during the first year of life with infant-directed speech.
    • Syllables are lengthened, as in stretching out "hello."
    • Phonemes are pronounced more clearly.
    • Consonant-vowel pairs followed by /b, p, m, g, k/ are not fully pronounced.
    • A change in vowel frequencies occurs when using infant-directed speech in English, Russian, and Swedish.

    Morphology/Syntax & CDS

    • Morphological variety in CDS can be beneficial.
    • This is shown by minimizing morphological complexities with diminutives in Russian.
    • CDS sentences are simple, short, grammatical, and often incomplete.
    • Subjects in CDS sentences tend to be agents, such as, "you're dancing" or "Eve can get the banjo."
    • Children use word meanings to learn syntactic structures.

    Repetition

    • CDS is repetitive, repeating and expanding on child utterances.
    • This might help with syntactic structure.
    • Adults use recast (minor variations in repetition/imitation of child speech) to provide more easily assimilated information to children.

    Vocabulary & CDS

    • Conversations between adults and children are often about the here and now, focusing on concrete concepts.
    • Common conversation topics include family members, animals, parts of the body, food, and clothing.
    • The amount of speech directed toward children can vary from 200 to 3000 words per hour, affecting vocabulary development.

    Does Help Help With Acquisition?

    • Consistent parentese and/or turn-taking can lead to language complexity in later development.
    • Naturalistic recordings are used.
    • Measures like percentage parentese, adult word count, conversational turn taking, and child vocalization count are used.
    • Quality, and not quantity, of child-directed speech predicts language outcomes.

    Universality

    • CDS is used cross-linguistically.
    • The preference for infant-directed speech is examined across multiple contexts.
    • Babies prefer infant-directed speech regardless of their linguistic environment or development.
    • Infant-directed speech is found to be cross-linguistically consistent.

    Interaction and Input

    • Does social interaction influence phonemic contrasts?
    • Live language group have greater sensitivity to Mandarin sound contrasts.
    • Social gating occurs when learning is enhanced through social interaction.

    Vocabulary & Input

    • Varying amounts of linguistic input impact word learning.
    • Children from lower socioeconomic status families tend to hear less speech than those from higher socioeconomic status families, impacting vocabulary development.
    • Vocabulary acquisition and language processing differ between high- and low-SES families, beginning as early as 18 months.

    Parental Responsivity

    • Babies are conversational partners.
    • Adults draw infants into communicative exchanges.
    • The basis is intentional communication (e.g., smiles, vocalizations, and laughs).
    • Adults respond to babies verbally and nonverbally.
    • Parents respond to children's verbal and nonverbal cues, creating a conversational exchange, based on examples from Brown (1973).

    Corrective Input

    • Recast: are minor speech variations in repeating or imitating child speech, supplying new or unfamiliar information that is easily assimilated by children.
    • Adults are responsive in child-adult conversations.

    "No Negative Evidence"

    • All language learners make errors.
    • There is no negative evidence; input does not show what is ungrammatical.
    • Evidence for corrective feedback exists from parents, using recast and disapproval responses to ungrammatical utterances.

    Contrastive Discourse

    • Children respond to corrections when given direct contrasting examples.
    • Change can be seen after weeks of correction, and correction is not always immediate, in child-directed conversations.
