Presentation Transcript

  1. Methods of child language research

  2. Techniques • Obersational studies • Experimental studies

  3. Observational studies • Diary studies [Stern and Stern 1907] • Analysis of transcripts [CHILDES] • Analysis of audio tapes [CHILDES] • Analysis of videos

  4. Observational studies • Longitudinal studies • Cross-sectional studies

  5. Experimental studies

  6. Why do we need experiments? *CHI: I am finished . *CHI: I missed . *CHI: he parked in the garage . *CHI: go put him in bed . *CHI: you took me three scrambled eggs . *CHI: They falled down . *CHI: She goed there .

  7. Rule vs. memory (rote-learning)?

  8. Experimental studies • Production studies • Comprehension studies

  9. Production studies • Elicited production • Elicited imitation • Elicited transformation

  10. Elicited production Berko-Gleason 1956

  11. Elicited production Berko-Gleason 1956

  12. Every day I gorp. Just like every day, yesterday I was … (rising intonation)

  13. Elicited imitation ADULT: I’ve got two foots. CHILD: I’ve got two … foots/feet. ADULT: This is my blue big tractor. CHILD: This is my … blue big / big blue … tractor.

  14. Elicited imitation (1) The boy the girl kicked went home. (2) The girl kicked the boy very badly and then he went straight home.

(3) There is the girl who Peter borrowed a football from. (4) This is the dog that the cat ran away from this morning. (5) There is the woman whose horse Peter heard on the farm.

  16. Elicited transformation ADULT: He’s going home… CILLD: Isn’t he? ADULT: They’ll take a long time… CILLD: Won’t they? ADULT: She can’t stay with us … CILLD: Can she?

  17. Elicited transformation ADULT: The man cleaned the bath. CILLD: The bath was cleaned by the man ADULT: The boy kissed the girl. CILLD: The boy was kissed by the girl.

  18. Comprehension experiments • On-line • Off-line

  19. Comprehension studies • Act out studies (off-line) • Picture pointing (off-line) • Reaction time studies (on-line)

  20. Act out (1) The dog pushes the cow. (2) The cow is pushed by the dog. (3) The deer pushed the donkey after it had kissed the lion. (4) The lion pushed the deer before it had donkey the dog.

  21. Picture pointing The duck pushed the chicken after it had kissed the dog. Who puched the chicken after it had kissed the dog?

  22. Infant studies • High-amplitude sucking procedure • Head-turn procedure • Preferential looking procedure

  23. Questionnaire studies

  24. Brain image studies
