Syntactic processing in bilingual aphasia
Danielle Fahey, PhD
University of Montana
Roughly half of the global population is bilingual in that they speak
(or sign) two or more of the world's 7000+ languages. Mainstream
psycholinguistic models of bilingualism propose a single language
system with grammars that interact across languages. Following this
theory, bilingual people with aphasia (bPWA) should have equivalent
deficits for grammatical structures that overlap between their
languages. Some research, however, has shown bPWA to exhibit
differential grammatical deficits in each language. Relatedly, the
complex syntactic structures known to be more difficult to process for
people with aphasia (PWA) are those acquired later by people learning
a second language. In this talk, I will present the state of evidence
regarding syntactic processing in bilingual aphasia, as well as an
innovative framework that my lab has launched for examining syntactic
impacts in bilingual aphasia, and some of our preliminary results. To
preview, in a systematic review, we find that the evidence regarding
parallel grammatical deficits (within an individual) in bPWA remains
inconclusive. The same is true when asking whether bPWA and
monolingual PWA (mPWA) present with equivalent deficits. Our work
addresses the major methodological and theoretical gaps in the extant
literature by matching mPWA as controls for bPWA, and examining
syntactic deficits by degree of featural overlap. We examine fully-,
partially- and non-overlapping structures in word order, morphosyntax,
and lexical syntax across 5 tasks. Although the results are
preliminary, our data suggest that fully-overlapping structures are
comparatively stronger than partially-overlapping structures for bPWA.
I will discuss the implications of these data for psycholinguistic and
neural models of bilingualism, aphasia, and the language system as a
whole.
