  59. 3 Theories of Language Development
    • Learning Theory
    • Nativist Theory
    • Interaction Theory
  60. What is the Learning Theory?
    • language as skilled behavior that children learn through operant conditioning, imitation, and modeling
    • Also called environmental view
    • Biological predispositions do not play important role
    • Based on behaviorist view of learning
  61. 4 Criticisms of Learning Theory
    • how consistent parents are
    • Language children hear is incomplete
    • Cannot account for novelty 
    • we are biologically predisposed to develop language
  62. What is the Nativist Theory?
    • innate human capability that develops when language input triggers a language acquisition device (LAD) in the brain
    • Children must hear some language to activate LAD, but extensive input not necessary
    • Language acquisition does not require great cognitive skill or effort
  63. What is Language Acquisition Device (LAD)?
    brain mechanism in humans that is specialized for acquiring and processing language
  64. Person behind Nativist Theory
  65. Specialized language structures
    • Wernicke’s area 
    • Broca’s area 
    • Arcuate fasciculus 
    • Angular gyrus
  66. What is Wernicke's Area?
    • in left temporal lobe
    • allows humans to understand words and produce coherent language
  67. What is Broca’s area?
    • left frontal lobe
    • directs patterns of muscle movements needed for speech production
  68. What is Arcuate fasciculus?
    band of fibers connecting Wernicke’s with Broca’s areas
  69. What is Angular gyrus?
    involved in processing written language
  70. Criticisms of Nativist Theory
    • Children do not always develop normal language independent of environment
    • researchers have not identified single universal grammar that applies to all languages
  71. What is the Interaction Theory: Cognitive?
    • Piaget’s cognitive developmental theory – language is one of several abilities that depends on cognitive development
    • Proper cognitive development is a prerequisite for normal language development
    • Only when children have object permanence and can use symbols to represent things are they capable of language
  72. What is the Interaction Theory: Social?
    • Language development results from interaction of biological and social factors and social interaction is required
    • Simply hearing language is not enough
    • Parents also communicate with children through structured and social games (Peek-a-boo, Itsy Bitsy Spider)
    • Also use motherese – child-directed speech
  73. 4 Prelinguistic Communication
    • Turn-taking: smile at pauses

  76. What are the linguistic stages?
    • First words
    • Two-word stage
    • Telegraphic speech
  77. What are first words?
    • extension of babbling – consonant-vowel pairings that are repeated
    • Shows understanding that words are symbols
    • –Characteristics (2 identical sounds, often)
    • Holophrases (“milk” means “I want milk”)
  78. Rules on word names
    • Mutual Exclusivity
    • Whole Object
    • Lexical Contrast
    • Taxonomic constraint
    • Sentence cues
  79. What is mutual exclusivity?
    If an unfamiliar word is heard in the presence of objects that already have names and objects that don’t, the word refers to one of the objects that does not have a name
  80. What is whole object?
    A name refers to a whole object, not its parts or its relation to other objects
  81. What is lexical contrast?
    When the name for the whole object is known, and another name is provided, the new name applies to a part of the object
  82. What is taxonomic constraint?
    words label categories of similar objects
  83. What are sentence cues?
    Words embedded in sentences with other words that are already known help children narrow down the meaning of words
  84. 2 naming errors
    • underextension
    • overextension
  85. 2 language learning styles
    • Referential Style: Vocabularies mainly consist of words than name objects, persons, or actions
    • Expressive Style: Vocabularies include some names but also many social phrases that are used like a single word (e.g., what’d you want?)
