Language Disorders Flashcards
What is a neurobiology in regards to threats to language acquisition?
- Brain structure and function abnormalities
What is etiology in regards to the threats to language acquisition?
premature birth
neurological disease
defective genes
abnormal communicative environment
early hearing problems
What are cycle linguistic processes in regards to threats to language acquisition?
fundamental problems in perception
fundamental problems in memory
fundamental problems in abstracting grammatical rules
What are the four phases to Locke’s model?
I- vocal learning
II- utterance acquisition
III- Analysis and computation
IV- integration and elaboration
What are the age ranges for each of Locke’s four phases?
phase 1 – vocal learning = prenatal to 5 to 7 months of age
phase 2 – utterance acquisition = 5 to 7 months through 20 to 37 months of age
phase 3 – analysis and computation = 20 to 37 months through three years of age
phase 4 – integration and elaboration = 3+ years through lifetime
What happens during a phase 1 – vocal learning of Locke’s model?
Orients to rhythm and prosody
Imitates/mimics prosody
Gets by in language
Turn taking
Sound play
What happens in phase 2 – utterance acquisition of the Locke’s model?
Collects utterances/”chunks”
Disorganized interns of the sound in semantic system
Stores/uses holophrases that have loose attachment to meaning
No grammar
Lexical spurt at 18 months
What happens in phase 3 – analysis and computation of Locke’s model?
Organized
Analyzes and recognizes patterns
Begins to produce those patterns
Grammar – syntax and morphology
What happens in phase 4 – immigration and elaboration in Locke’s model?
Vocabulary increases
Group information in categories
Learn concepts more easily
Integrate new linguistic information more easily
Elaborate at richer linguistic levels
What systems of language development during phase 1 – vocal learning of Locke’s model?
Pragmatics
Prosody
Phonology
What systems of language develop during phase 2 – utterance acquisition of Locke’s models?
Pragmatics
Prosody
Phonology
Semantics
What’s the symptoms of language developed during phase 3 – analysis and computation of Locke’s model?
Pragmatics Phonology Prosody Morphology Syntax Semantics
What’s systems of language developed during phase 4 – integration and elaboration of Locke’s model?

What are the three threats to language acquisition?
