Methods of child language research
Techniques
• Obersational studies
• Experimental studies
Observational studies
• Diary studies [Stern and Stern 1907]• Analysis of transcripts [CHILDES]• Analysis of audio tapes [CHILDES]• Analysis of videos
Observational studies
• Longitudinal studies• Cross-sectional studies
Experimental studies
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 .
Rule vs. memory (rote-learning)?
Experimental studies
• Production studies• Comprehension studies
Production studies
• Elicited production
• Elicited imitation
• Elicited transformation
Berko-Gleason 1956
Elicited
production
Berko-Gleason 1956
Elicited
production
Every day I gorp.
Just like every day, yesterday I was … (rising
intonation)
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.
Elicited imitation
(1) The boy the girl kicked went 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.

ADULT: He’s going home…CILLD: Isn’t he?

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.
Comprehension experiments
• On-line
• Off-line
Comprehension studies
• Act out studies (off-line)
• Picture pointing (off-line)
• Reaction time studies (on-line)
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.
Picture pointing
The duck pushed the chicken after it had kissed the dog.
Who puched the chicken after it had kissed the dog?
Infant studies
• High-amplitude sucking procedure
• Head-turn procedure
• Preferential looking procedure
Questionnaire studies
Brain image studies
