Week 23 - More on Language Acquisition Tuesday, March 26, 2019 4:01 PM - Early in borrowing, sounds are adapted to the inventory of the borrowing language. E adapts to [ae] instead of [a] Three stages of development: - Case-by-case (memorization of whole forms) ? Memorizing irregular forms like 'went'. - Overgeneralization (goed, runned) ? Start using incorrect forms from overgeneralization of grammatical rules like pa Applying regular morphology to irregular verbs. - Correct use (adult-like). ? Figure out the irregular forms and begin using them with more accuracy. Order of Morphological Acquisition - Order of production ? -ing ? -s (plural) ? 's (poss) ? The, a ? -ed (past) ? -s (third person sing) ? Auxiliary BE - Frequency (of what children hear) ? The, a ? -ing ? -s (plural) ? Aux BE ? 's (poss) ? -s (third) ? -ed (past) - Thus frequency doesn't totally explain the order of acquisition. Syntactic Development h 1 d
Syntactic Development - ~ 12-18 months: 1 word stage - ~ 1.5-2 years: 2 word stage - ~ 2-2.5 years: telegraphic stage. Perception vs Production in Syntax - Perception precedes production. o Example, Y/N questions. Can respond yes or no before being able to make questions, indicating they understand questions. - Children do not initially have T->C movement to create questions, and make questions using intonation only. Doubling auxiliary also occurs (Is kitty is friendly?). - WH-Questions emerge later, between 2 and 4. Often lack inversion, even when children properly apply it in Y/N Qs. Example, 'What you are doing?" can move the Wh, but the auxiliary doesn't move. - Passives Studying Language Acquisition - Naturalistic ? Longitudinal - Experimental ? Cross-sectional · Comprehension vs production ? Repetition Factors in Language Acquisition - Experience. The language spoken around you is what you acquire
