code switching: guest lecture

chomsky vs macswan pov of bilingual cogn processes

chomsky: duplicated language route

macswan: adaption model to provide for code switching

code switching: what underlies it? is it always same mechanisms?

systematic mechanism from underlying grammar

how can indirect measures be targeted in code-switching studies

thru EEG scans, get electrical activity

benefits & cons of EEG scans

non-invasive, high temporal

cons: tedious set up, low spatial

N400 effect for EEG scans on code switching

represent semantic processing difference — represent effortful process in code-switching

P600/LPC singificance code switching studies

morpho-syntactic processing, represent cognitive control

overall conclusions from habitual vs non habitual code switchers

habitual show LPC effects, but no N400 (code switching not effortful),

non-habitual show P600/LPC & N400 effect— code switching is effortful for trhem

do bilingual code switchers exhibit inhibtiory cogn control advantages?

yes— perform better on stroop tasks/cogn tasks

what did gosselin find abt relationship btwn how ecologically valid samples r processed & how methodlogical approaches r processed

processed similarly— both r good measures for testing, balance is fine
