Lecture 3 ( Chapter 1 & Chapter 3 )- Issues, Theories, and Methods
Research on language acquisition
Not going to cover general experimental design, assuming you know it
Only focusing on procedures and techniques
Productive and receptive language
Methods of Research in Language Development
Spontaneous or structured speech samples
Listen how people talk, how they speak in natural context, or provide them speech samples,
allow us to assess different aspects of language, ex, grammar... whether people have accent
Minimum 50 utterances but often much larger (when we use and assess speech samples)
→LENA (Language Environment Analysis)
→Kids wear a recorder, patterns are automatically analyzed
→LENA
→Research + home, classroom, parent training
→Best to use AV ( audio-visual - we want a recording of the speech )
→Transcribe for component of interest
→e.g., MLU (average length of utterance - how many
morphemes in children utterance)
→Inter-coder reliability (different people/ researchers have the
same summary for the measures)
What is MLU
I have to eat
Um. Doggie’s hungry
Doggie eated
I hafta go eat
More methods
Analyzing speech samples is time-consuming (transcription)
Data Archive: CHILDES
→Larger sample of naturalistic speech than any one study
→Linked with some analysis options
Document Summary
Lecture 3 ( chapter 1 & chapter 3 )- issues, theories, and methods. Not going to cover general experimental design, assuming you know it. Listen how people talk, how they speak in natural context, or provide them speech samples, allow us to assess different aspects of language, ex, grammar whether people have accent. Minimum 50 utterances but often much larger (when we use and assess speech samples) Kids wear a recorder, patterns are automatically analyzed. Best to use av ( audio-visual - we want a recording of the speech ) E. g. , mlu (average length of utterance - how many morphemes in children utterance) Inter-coder reliability (different people/ researchers have the same summary for the measures) Larger sample of naturalistic speech than any one study. Filling the blank - are they using the correct word or following the rules - we are driving what the children are going to say.
