Objective
How does manipulating top-down resources and bottom-up speech input differentially influence language processing in the first (L1) and second (L2) language of bilinguals? Are there differences in the intelligibility thresholds for degraded stimuli in L1 and L2?
We will test late bilinguals in two event-related functional magnetic resonance imaging (fMRI) projects. The first will involve examining how breaking down the bottom-up information (i.e.; the speech stimulus) differentially influences speech perception and its underlying neural activity in the two languages.
Word pairs will be degraded by being presenting in noise using the SPIN paradigm. There will be speech, and speech plus noise conditions. In both, subjects will hear pairs of either related o r unrelated words, followed by a visually presented word, and will have to decide if the first word of each pair is the same or different as the visually presented word.
The second project will involve examining how manipulating top-down, 'executive' functions differentially influence speech perception in L1 and L2, and its underlying neural correlates, in the same individuals. We will again present related and unrelated word pairs, and will manipulate executive resources by adding auditory cues, auditory distractors, or a distractor task.
We expect that subjects will be less hindered by the noise during task performance in L1 than in L2, and further, that individuals will make better use of the contextual information (relatedness) in L1 than in L2. Executive and attentional control processes, subserved by the dorsolateral prefrontal cortex and the anterior cingulate, may differentially be involved in the speech plus noise condition across languages.
We expect that in L2, attentional cues will help subjects to partly recover from deficits in performance due to noise, and that attentional distractors and an increased working memory load will further diminish their performance.

Funding Scheme
Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
