Is there a critical period for grammatical features? Foucart et al
French has grammatical gender system
Natives systematically acquire grammatical knowledge of gender
assignment + rules at young age - affects syntactic processing
English relies on semantic gender + agreement more limited to pronouns
So can English natives acquire grammatical gender when learning French in native-like manner?
NO
Schwartz + Sprouse - full transfer full access model
During initial stages of L2 acquisition, rep of grammatical features based on those in L1.
Throughout life span, learners have access to underlying UG.
= new, even uninterpretable features can be native-like acquired any age
YES
Several observational studies concluded that after critical period, no longer able to acquire abstract grammatical features not in their L1
Failed Functional Features Hypothesis - Hawkins et al
new interpretable features can be acquired, new uninterpretable features can't. Patty example.
Compared French natives to English-French adult learners -
proficiency high enough for learning French at uni
Age at start of instruction 10-18
ERP data recorded + eye movements by electrodes, and questionnaire
questionnaire - natives rejected more
sentences with gender violations (95%) than
L2 learners (40%)
L2 learners elicited P600 effect similar to native's but reduced amplitude
= highly proficient L2 learners can reach native-like processing levels even if learned L2 late in life
