Show moreThis study addressed the debate on the primacy of syllable vs. segment (i.e., phoneme) as a functional unit of phonological encoding in syllabic languages by investigating both behavioral and neural responses of Dutch-Cantonese (DC) bilinguals in a color-object picture naming task. Specifically, we investigated whether DC bilinguals exhibit the phonemic processing strategy, evident in monolingual Dutch speakers, during planning of their Cantonese speech production. Participants named the color of colored line-drawings in Cantonese faster when color and object matched in the first segment than when they were mismatched (e.g., , /laam4/ /lok3to4/, "blue camel;" , /hung4/ /lok3to4/, "red camel"). This is in contrast to previous studies in Sinitic languages that did not reveal such phoneme-only facilitation. Phonemic overlap also modulated the event-related potentials (ERPs) in the 125-175, 200-300, and 300-400 ms time windows, suggesting earlier ERP modulations than in previous studies with monolingual Sinitic speakers or unbalanced Sinitic-Germanic bilinguals. Conjointly, our results suggest that, while the syllable may be considered the primary unit of phonological encoding in Sinitic languages, the phoneme can serve as the primary unit of phonological encoding, both behaviorally and neurally, for DC bilinguals. The presence/absence of a segment onset effect in Sinitic languages may be related to the proficiency in the Germanic language of bilinguals. Show less

Show moreThere are around 7,000 different languages. The unique orthographic characteristics of different languages can help us to gain insight into the seemingly simple process of transforming written script to spoken words (i.e., reading aloud). In this thesis, using behavioral and electroencephalography (EEG) measures the time course of reading (aloud) was investigated in first, second, and cross-language situations. Overall, target words (e.g., CARPET) were read aloud faster when preceded by phonologically (e.g., kettle) but not orthographically onset-related primes (e.g., circus). However, this pattern was absent during silent reading and reading in Persian where words are printed without vowels. EEG data revealed both orthographic and phonological activation about 150 milliseconds after target presentation for all situations and languages. These results suggest that reading starts with same processes __ whether silent or aloud or in different scripts. Additionally, even if we have an accent in a second language, the phonological code is activated similarly as for a native speaker. To conclude, this thesis favors computational models assuming early conversion of orthography-to-phonology. However, with approximately half of the world__s population being bilingual and the results presented in this thesis, it is important that computational models of reading processes extend their horizon.
