a child bounded all her life and not allowed to speak
How do infants acquire language?
What is thought?
What shortcuts do people use when problem solving?
Shortcuts are heuristics
Yes you can be scared to death – excessive death, happiness, intercourse.
How many morphemes are in the word, “crosswords”?
First check the root words. Crossword is the root word + the s which makes it plural
Critical thing when looking for morphemes is to look at rootword
Surface vs Deep Structure
Hardwired for language acquisition evidence…
High pitch, slow rate, exaggerated tone
Adults shift “automatically”
Infants prefer this type of speech to normal adult speech
Learning about pausing, pitch, characteristics, etc.
The one word speaker
5 to 8 months of age, respond to parents’ words
Talking begins 10 to 20 months
Early vocaubulary simple
Nouns (mama, duck)
Interactions (hi, peekaboo)
Adjectives (hot, big) #1 word that infants have??
Likely to contain objects that infant can manipulate (“ball” more likely than “ceiling”)
Difficult to tell what kids mean when they use single words
Tend to under generalize ex. “cat” as a name or a category of animal
The two word speaker
Starts around 2 years old
Vocabulary – several hundred words (about 300 or 400)
Speech shows proper organization
“throw ball” not “ball throw”
They’ve picked up syntax even though no one taught them.
Does this imply that syntax is inborn or hard wired?
By 2 and half years child moves beyond 2 words and sentences become more complex
Vocab around 800 words
Start searching for rules of generalization (ex. The cat can be more than 1) The 4 or 5 year old makes mistakes in tense
Eg. “runned” not “ran” , “eated” not “ate”
Child now overgeneralizes rules
Formal schooling takes over
Will language develop “on its own”?
Did they learn language after reintroduction into society? For following:
A. Wild Children
Consider Amala (1.5 years old) and Kamala (8 years old)
Living with a wolfpack who had adopted them
They were wolfish and had wolf like characteristics
Amala died but Kamala’s reintroduction to society didn’t work too
