    Naming errors
    Retrieval errors that children (and adults) make are often related to the word that was targeted for expression. Therefore errors in word retrieval reflect a speaker's knowledge.

    If a target word is dog the child's error is more likely to be animal than spoon because dog and animal are closely related in lexiocn than are dog and spoon

    Factors Influencing Mapping
    -Child's learning style
    -Phonetic composition
    -Syllable structure-simpler, quicker
    -Situational variables-will learn it more quickly if they are exposed to it
    -Linguistic context
    -if there are a lot of words in a sentence they already know
    -if they already know words in that category (red, already know yellow)
    Simple phonetic makeup-mapped more quickly

    Development of Relational Words
    -Begins in preschool years-not concrete words, harder to see
    -Dimensional words are adjective pairs used to indicated dimensions of objects
    -paired-one member indicated the presence of size (unmarked "big") the other is the absence of size (marked "little") Presence of something is more tangible, easier faster to learn than the absence of something
    -Color words name colors-age 4, consistently name color
    -Spatial words indicate location-huge amount of ideas
    -Kinship words indicate relationship among family members (difficult)
    -will master immediate relationship first (their own), then understand other relationships (wife, daughter, husband, etc)

    Word relations
    how meanings of words react w/ each other in various environments

    Semantic Development in School Years
    Continued fast growth
    -fast grade-> comprehend approx. 20,000 words
    -Sixth grade -> comprehend approx. 50,000 words
    -High school -> comprehend approx. 80,000 words

    -increase in exposure brings about new words and expands meaning on existing words
    -use words more flexibly and consistently
  • kgiambruno
    Horizontal development
    Associating additional features with a word

    broadening idea of same word/meaning
  • kgiambruno
    Vertical development
    Learning separate, multiple meanings of words

    different meanings- "block toy vs. neighborhood block"

    Classification of Sounds
    Phoneme -smallest arbitrary unit of sound in a given language that can be recognized as being distinct from other sounds in the language
    -Our language has 44 phonemes represented in the IPA
    -Phonemes are classified in terms of their similarities and differences in pronunciation
  • kgiambruno
    We classify sounds according to
    -Source of sound in the vocal tract
    -Shape of the vocal tract during production
  • kgiambruno
    Sound classes-Vowels
    Classified mainly according to the source (location of articulation)

    -Vocal tract is relatively unobstructed
  • kgiambruno
    Sound Classes-Consonants
    More constricted vocal tract
    Classified based on 3 aspects of production
    -place of articulation
    -manner of articulation (way sound is produced)
    Fricatives, stops, affricative's
