(32 cards)
What is the typical language behavior at birth?
No specific language behavior observed.
What is cooing?
Non-linguistic sounds produced by infants, typically occurring at 1-2 months.
What is babbling?
Linguistic sounds produced by infants, typically occurring at 8 months.
What is holophrasing?
Using single words to express full ideas, typically occurring at 15-18 months.
What is a vocabulary spurt?
A rapid increase in vocabulary, typically occurring around 18-24 months.
What are telegraphic phrases?
Two or three-word phrases that convey meaning, such as ‘mummy go,’ typically occurring at 18-24 months.
What is the language behavior at 2-3 years?
Children begin to use full sentences.
What language skills develop by 5 years?
Children demonstrate complex grammar and syntax.
What is cooing?
Gurgling, vowel-like sounds produced by infants.
What is marginal babbling?
Playing with pitch and pronouncing syllables.
What is canonical babbling?
Reduplicated sounds (e.g., ba-ba-ba) and non-reduplicated sounds (e.g., ba-bi-ba-bi-bu).
What is the receptive vocabulary?
The ability to recognize and understand words, typically developing by 4 months.
What is spoken vocabulary?
The ability to begin producing words, typically developing by 12 months.
What is the production lag?
Children understand more words than they can say.
What was the Deb Roy Study?
A study that recorded language development at home, showing caregivers simplify utterance length before new word production.
What is joint attention?
When a child and adult focus together on the same object, aiding in word learning.
What is the mapping problem in word learning?
The challenge of associating words with their meanings.
What is the vocabulary spurt?
A sharp increase in word learning speed around 18 months.
What is mutual exclusivity?
The assumption that each object has one label.
What are taxonomic assumptions?
The belief that new words extend to similar category members.
What is semantic bootstrapping?
Inferring syntax from meaning.
What is syntactic bootstrapping?
Using sentence structure to infer word meaning.
What are hoophrases?
Single words that convey full sentences (e.g., Milk).
What is telegraphic speech?
Two-word combinations without function words (e.g., ‘me fall’).
