02 Contents Introduction How independent are the language of multilingual speakers? Multiple language structure in the brain Relationship between L1 & L2 in brain organization Language when brain damage
Introduction 03 ,[object Object]
He noted that an injury to the left side of the brain was much more likely to result in language loss than was an injury to the right side.,[object Object],[object Object],[object Object]
 As brain matures and has less plasticity: an area of the brain becomes less able to assume the functions of another in the event it is damaged.,[object Object],[object Object],[object Object],[object Object]
Right hemisphere is responsible for the movement and nonlinguistic. Ex. Visuospatialinformation.
This is due to left hemisphere ‘s being computationally more powerful than the right and therefore better suited for processing the highly complex elements of language.,[object Object]
Introduction (cont’) 12 ,[object Object]
 Methods of Gathering Data of the Brain:
Correlation of location
Presentation of stimuli from different languages
Mapping the brain
Positron Emission Tomography
 Questions remain unanswered or answers remain controversial,[object Object]
How are multiple language structures organized in relation to one another in the brain? Are both languages stores in the same areas? 14 For at least some multilinguals, it appears that L1 and L2 are stored in somewhat different areas of the brain, but both are predominantly in (probably overlapping) areas of the left hemisphere.  The area common to both L1 and L2 storage is near Sylvian fissure in the left hemisphere, but L1 or L2 (more likely L2) is disrupted by stimulation of points further away from the Sylvian fissure.
Does the organization of the brain for L2 in relation to L1 differ with the age of acquisition,  how it is learned or level of proficiency? 15 ,[object Object]
 Age of acquisition influences brain organization.   -  Vaid (1993): acquiring L2 later in life involves 	more right hemisphere.    -  Wuillemin and Richards (1994): acquiring L2 	(age 9-12) involves more right hemisphere than 	before age 4.
16 ,[object Object],     -   The organization of L2 knowledge is more diffuse for lower levels of      	proficiency 	and more compact for higher level.      -   Fedio et al. 1992: A multilingual person may use more memorization for 	L2 and    	more direct processing of meaning for L1.      -   Other research: L2 learners increase reliance on meaning over memory   	as their 	proficiency in L2 increases.
