  1. infant directed speech in western speakers
    • unique speech register used by adults in western cultures to talk to infants from birth 
    • characteristics:
    •    high overall pitch
    •    exaggerated pitch contours
    •    slower tempos in comparison to adult-directed speech
    • simplfying characteristics of id are not present in all cultures
    • id speech of different cultures ranges in its communicative accomodation from highly child-centered to highly situation-centered
  2. dialects
    • dialects are regional or social varieties of lang that differ form one another in terms of pronunciation, vocab, grammar
    •    develop over a prolonged period when people are separated by geographical or social barriers
    • everyone speaks some dialect or variety of a lang
    • in general people who speak different dialects of a lang can understand on another
  3. accents
    varieties of lang that differ solely on pronunciation
  4. what is perceived to be the highest status in the us
    standard american english

    • in england it is received pronunciation
    • children develop the perceptions of higher status sounding english at an early age and it is perpetuated throughout life
  5. magic boxes study
    children selected the talking box that spoke GAE (GENERAL AMERICAN ENGLISH) because it talked better
  6. AAVE
    • African American Vernacular English
    • phonological differences: consonant cluster reduction
    •     old=ol', west=wes', deletion of suffix-s= she drive and possessive suffix 's=my sister ca
    • grammatical differences: distinctions between habitual
    •     anita be working, (reg) temporary- anita working (at the time)
    • phonological inversion
    •     /ask/=/aks/
  7. pidgins
    • simplified type of lang that develops when speaker who do not share a common lang come into prolonged contact with another lang
    • have no native speakers, used as a 2nd lang, particularly in situations where they are conducting business with one another
    • utilize the lexicon of the most dominant of the 2 langs and the phonology and syntactic structure of the less dominant lang
    •    Hawaiian Pidgen=ENglish and Philippine langs
  8. Dual lang learners
    people who acquire 2 or more langs throughout the course of their lives
  9. bilingualism
    the process whereby children essentially acquired 2 first langs
  10. multilingualism
    acquire more than 2 first langs
  11. simultaneous bilingualism
    • acquire 2 or more langs from birth, or simultaneously
    •    receive lang input in 2 or more forms from parents, grandparents, other close relatives or childcare providers
  12. majority ethnolinguistic community
    • group that speaks a lang that the majority of people in an area value and assign high social status
    •    generally persons share cultural and ethnic backgrounds 
    •    official or unofficial "standard" in the community
  13. minority ethnolinguistic community
    • a group that speaks a lang that few people in the community speak or value
    •   may have lower social status
    •   may receive little or no institutional support
  14. sequential bilingualism
    • learn tow first langs in succession, usually within the first three years of life before developing proficiency in the first of the two langs
    • some kinds of advantages and setbacks as children who acquire multiple langs simultaneously, depending on their status in a major or minor ethnoliguistic community
  15. unitary lang system hypothesis
    • mastering one at a time
    • children are not bilingual until they successfully differentiate between the 2 langs
  16. dual lang system hypothesis
    • mastering two at a time
    • does not presuppose that children move through stages whereby they come to differentiate between two langs
    •     bilingual children establish 2 separate lang systems from the outset of lang acquisition
    • research favored
  17. code switching
    • or code mixing
    • speakers alternate btw langs when they have more than one lang in common
  18. intrautterance mixing
    • alternation occurs within a single utterance possible two words as opposed to a sentence 
    • yeah, ok
  19. intrasentential mixing
    alternation occurs within one sentence
  20. interutterance mixing
    alternation occurs btw utterances
  21. intersentential mixing
    alternation occurs btw sentences
  22. what do children use more within the elements of code switching?
    interutterance mixing more than intrautterance mixing, especially in the 1-word and 2 word stages of development
  23. reasons for code switching
    • fill in lexical or grammatical gaps
    • lack translation equivalent for a word, no matter whether using more proficient or less proficient lang
    • pragmatic effect
    • social norms of their community
  24. second lang acquisiton
    • sla
    • the process by which children who have already established a sold foundation in their first lang (L1) learn an additional lang
    • sla usually does not occur in school, either as the majority lang for a community or as a foreign lang
  25. interlanguage
    • during L2 acquisition, speakers create lang system called interlang
    •    includes elements of L1 and 2 plus elements not found in either lang
    •    by combining lang from L1 and 2 you create lang that does not exist
  26. language stablization
    occurs once the interlang stops evolving and L2 learners reach a plateau in their lang development
  27. language fossilization
    • to become permanently established in the interlanguage of a second lang learner in a form that is deviant from the target lang norm-continues to appear regardless to further exposure to the target lang
    •    learn to refer to the changed word even after you have acquired the actual word in both langs
  28. tu
  29. English as a second language
    • learning english after they have L1
    • english as an additional lang (EAL) when they speak two or more langs learns english
    • english language learner (ELL) used in schools to designate child with limited english proficiency

    lang diff: normal variability we see among children in their lang development
  31. language difference v. language disorder:
    implications for not correctly differentiaign lang diff v disorder
    • failure to provide needed therapy when appropriate-they don't outgrow it
    • over-identification of minority students-stigma out of classroom disproportionality
  32. language difference v. language disorder:
    cultural context
    • a cultural community's approach to socializing children can influence the amount and quality of lang that children experience in their home and community
    • ex: seen and not heard, eye contact, socialization: children don't talk unless spoken to etc

    •    -
  51. open head injuries
    • brain matter exposed through penetration, as would occur with a gunshot wound
    • CHI AND OHI the immediate injury to the brain is often accompanied by secondary brain injuries that result from the primary trauma
    • injury to brain usually damages the frontal and temporal lobes of the brain, which house the centers for much of our executive and lang functions
  52. language disorders resulting from brain injury are influenced by:
    • the severity
    • the site of damage
    • the characteristics of the child before the injury occurred

    • hearing loss present at birth
    •    -about 50% of cases have unknown reasons
    •    -more prevalent causes include genetic transmission, in-utero infections, prematurity, pregnancy complications and trauma during birthing process
  61. acquired hearing loss
    • hearing loss that occurs after birth 
    •    -prominent causes include: noise exposure, infection, use of ototoxic medications, and chronic middle ear infections
  62. prelingual hearing loss
    acquired after birth but before the child has developed lang
  63. postlingual hearing loss
    acquired sometime after the child has developed lang
  64. what 4 factors that determine the extent to which hearing loss impacts childs development
    • timing of the loss
    • severity
    • age of identification
    • exposure to lang input
  65. cochlear implants
    • new approach to intervention for children 12 months and up with severe to profound hearing loss
    •     surgical implantation of a receiver-stimulator (in hollowed portion of mastoid bone)and electrode array (in the cochlea), which accompany external hardware worn by the user (mic, speech processor, transmitter, power supply)
