1-4 - Prelinguistic Development: Production Flashcards
What question does Speech Production attempt to answer?
What does the infant articulate?
What question does Speech Perception attempt to answer?
What does the infant discriminate?
What hypothesis of Speech Production did Jakobson offer?
Infants babble all sounds
It’s the infant practicing
Is there evidence to support Jakobson’s theory?
There is no evidence to support this
What hypothesis of Speech Production did Locke offer? How accurate was he?
Infants follow invariant stages
The range of speech sounds is not random; they are specific to the current stage.
Stops are more common. Fricatives are rare.
This was almost right
What hypothesis of Speech Production did de Boyssons- Bardies offer?
Infants follow stages with environmental effects (languages used around them) between 0;8 and 1;0
Babbling starts taking on native language characteristics about the same time as first words
What are the three methods to studying child speech production?
Study anatomical changes of speech tract
Transcribe speech sounds (adapt for properties above)
Perceptual tasks
Is transcription of infants easy to do?
No
What sort of perceptual tasks are used to study child language production?
Asking listeners to ask what language infants are babbling in
What are the three differences between the infant and adult speech tracts?
Tongue size (large) and movements (front-to-back)
Pharynx
Respiration
How did Betty Stark study child language production?
Auditory judgement-spectral feature
Listen & use spectrograms (Does it sound like a stop, fricative, etc.)
No specific sounds
How did Oller study child language production?
Functional categorization
Is the child yelling or not?
Is the child blowing a raspberry?
What are Oller’s Stages?
Reflexive crying & vegetative (burping, throwing up, etc.) sounds
Cooing & laughter
Vocal Play
Canonical Babbling
Jargon
When does Oller’s Stage of Reflexive crying & vegetative sounds occur?
0;0 to 0;2
What happens during Oller’s Stage of Reflexive crying & vegetative sounds?
Burping, throwing up, etc.
When does Oller’s Stage of cooing & laughter occur?
0;2 to 0;4
What happens during Oller’s Stage of cooing & laughter?
Intentional sounds
Oller liked to call it “gooing” instead of “cooing”
When does Oller’s Stage of vocal play occur?
0;4 to 0;6
What happens during Oller’s Stage of vocal play?
Raspberry, squeal, yell, growl, etc
Allows the child to practice speech parameters
When does Oller’s Stage of Canonical Babbling occur?
0;6 and onward
What happens during Oller’s Stage of Canonical Babbling?
Reduplication (Repeated consonant)
Variegation (Same Cs, Different Vs. Different Cs, Same Vs. /didodidodido/, /gogigogi/)
Not all babbling is canonical, but most of it is
When does Oller’s Stage of Jargon occur?
0;10 and onward
What happens during Oller’s Stage of Jargon?
Sentence like productions but meaningless
Sounds like real language but there’s no meaning to it
What speech parameters does vocal play allow an infant to practice?
Pitch
Loudness
Timing
Resonance
