Language learning in monolingual and bilingual infants: Evidence from electrophysiological and optical signals


Bilingual infants have to deal with two languages at the same time. Some previous studies showed delayed processing in bilinguals due to the higher cognitive load they are faced with. However, other studies show that they master this challenging task with a fascinating ease and at the same pace as monolingual infants. In order to get clearer insights into language learning processing mechanisms in mono- and bilingual infants we will adopt a statistical learning paradigm in which 6 and 18 month old infants listen to phonotactically legal and illegal pseudowords presented in combination with different pseudoobjects. Phonotactics is a prelexical cue relevant for segmentation and lexical access and thus playing a crucial role during word learning. Legal phonotactic rules will correspond to German, whereas illegal rules will correspond to the Slovak language. Monolingual infants will have German as their native language and bilingual infants will be confronted from birth with German and Italian. Thus, the experimental material reflects processing of the native language compared to a foreign language rule. In order to be able to differentiate fine-grained language learning mechanisms we will adopt simultaneously two neuroscientific methods: the electroencephalography (EEG) and the functional near-infrared spectroscopy (fNIRS). The former allows an exquisite temporal resolution aiming at identifying temporal characteristics of fast processing mechanisms and the latter will focus on topographic issues, especially on lateralization. The research questions of the present study focus on whether bilinguals are more flexible learners than monolinguals providing superior learning abilities with respect to a new language or whether a word-object associative learning context provides a more laborious learning setting and thus leading to delayed and differential processing mechanisms, both on a temporal level as well as with respect to recruitment of differential brain areas.
