This project investigates the hypothesis that the two languages of bilinguals involve a common semantic-conceptual system. This hypothesis will be examined in early and late French-German bilinguals for both perception and production, using a new methodology in functional Magnetic Resonance Imaging (MRI).
A series of priming-experiments examines the neuronal representation of word meanings in L1 and L2 using functional MRI. AOA of L2 will be systematically manipulated in highly proficient bilinguals (2 levels: group 1 = early bilinguals; group 2 = late bilinguals). To test the generalisability of the results the mode of of stimulus presentation will be varied systematically (i.e., visual, auditory, pictorial presentation).
Hypothesis 1
If AOA of L2 plays a role in semantic processing in bilinguals with similarly high proficiency, then different neuronal populations should be active in a semantic task in early but not in late bilinguals.
Hypothesis 2
If
not, then the same neuronal populations should be active in a semantic task in
early as well as in late
bilinguals.
