IntroductionOpinion • According to you, what does a child need to learn in order to “know” his or her language?
Three general theories of language acquisition: Innateness Theory Imitation Theory Reinforcement Theory Interactionist Theory (or Constructivism)
IntroductionOpinion • According to you, how does a child learn a language?
Theories of language acquisitionInnateness Theory • Children have the _________ _____ to differentiate phonemes, extract words from the stream of language, and process grammar. Rowe & Levine (2012). A Concise Introduction to Linguistics, p .237.
Theories of language acquisitionImitation Theory • Children learn grammar by _________ the words and sentences of their language • Problems with this theory: • Children produce many things that are not found in _________ _________ • Children make consistent ______that cannot be attributed to mispronunciation and which still are not ever heard in the adult grammar. • Children can produce and understand _________ _____
Theories of language acquisitionReinforcement Theory • Children learn to speak like adults because they are taught to do so: • Through _________ and _________ when speaking “correctly”. • Through _________ when making “mistakes” • Problems with this theory: • Adults don't seem to correct children's grammar as much as we might think, neither do they praise them for using proper adult grammatical constructions. • There is little evidence that reinforcement has any great effect on the language development of the child
Theories of language acquisitionInteractionist Theory • Children "invent" the rules of grammar for themselves • Though it is based on the _________ _________ • Innate ability to _________ _________ • Only approach that explains how children • Produce _________ _________ • Ex: Past tense - goed* or hitted* • Generate _________ ______that they have never heard • Seem almost impervious to correction from adults
Theories of language acquisitionInteractionist Theory • Irregular verbs acquisition - Past tense: • Children acquire some irregular past tense forms quite early through memorization • Then the child starts to notice a general “rule” for past tense formation • This results in ______________(ex: goed*) • Finally the child realizes that “went” is an _________

Contemporary Linguistics: p.317 ... Aspects of Language AcquisitionSemantic Acquisition • Semantic acquisition is how children acquire _________ & _________ • Children need to learn: • Nouns (Concrete vs. abstract) • Verbs • Adjectives • Pronouns • Articles • Etc.
Aspects of Language AcquisitionSemantic Acquisition • To learn word meaning children basically have to make guesses about what words mean • Example …
Aspects of Language AcquisitionSemantic Acquisition • For example: A child is exposed, for example, to a poodle in the street and sees mommy or daddy point to it and say "doggie". Even if the kid associates "doggie" with that object, there are a number of routes that the child can logically take. The child might see a squirrel and say, "doggie", clearly having taken the word "doggie" to mean something more general that it does in the adult grammar. Or, the child might see a dog, say a “labrador”, and not say anything, failing to associate the word "doggie" with anything beyond poodle-ness. This trial and error process seems to be how children acquire word meanings.
Contemporary Linguistics: p.320 Aspects of Language AcquisitionSemantic Acquisition • Overgeneralizations (or overextensions): • Overgeneralizations are cases in which a child gives a word a ____________ ____________ that it has in the adult grammar • E.g. Using the word "fly" to include specks of dirt, dust, small insects, and bread crumbs
Contemporary Linguistics: p.320 Aspects of Language AcquisitionSemantic Acquisition • Underextensions: • Underextensions have the opposite effect. In this case, it might help to think of them as cases in which the child is being ____ ________ • E.g. A child who calls “a ball” “a ball” only when it is under the sofa • E.g. Underextended the word "fruit" as to exclude olives
KIDS SAY THE DARNDEST THINGS !!! • My cousin's daughter looked at my feet the other day and saw the state of my torn shoes. • She looked over to her mother and said: "Mommy, look. She had broken feet!“ • Classic example of overextension of “feet” :)
IntroductionExample of Child’s Speech • CHILD: My teacher holded the baby rabbits and we patted them. • ADULT: Did you say your teacher held the baby rabbits. • CHILD: Yes. • ADULT: What did you say she did? • CHILD: She holded the baby rabbits and we patted them. • ADULT: Did you say she held them tightly? • CHILD: No, she holded them loosely.
Aspects of Language AcquisitionMorphological Acquisition • Plurals: • Plural suffix is acquired __ • Then there is overgeneralization as the child is building a grammar • (Ex: sheeps, foots)
Aspects of Language AcquisitionMorphological Acquisition • Suffixes • Example: Church kids
