Q

four

What are some of the main criticisms with innate constraints theory on word learning?

A

Do constraints explain word learning or just describe it?
How does this theory work for non-noun words?
Are constraints innate or learned via experience?
Little research on infants.

Q

4 Criticisms

What are the main criticisms of syntactic bootstrapping?

A
  • Not clear exactly what parts of sentences children are listening to.
  • The chicken and the egg… Some knowledge of words and word categories is needed to understand their structure.
  • Do studies reveal something about long term word meaning, or immediate problem solving ?
  • Structural information can’t solve all the problems
    • The man’s tamming over the bridge
    • Tamming = walking or strolling or going
17
Q

What is the social-pragmatic approach to word-learning?

A

Children learn words and word meaning from pragmatic cues in the environment which remove ambiguities around word meaning.

18
Q

constraints

What are the 2 constraints in the social-pragmatic approach?

A

Social Structure - Routines, games, patterned social interactions
Child’s social-cognitive skills - joint attention, intention reading

19
Q

two

What are the main criticisms of the social-pragmatic approach to word learning?

A

What kinds of inferential skills does the child bring to the task of language acquisition?
Can this process of learning account for the acquisition of complex syntax?
