Does phonological overlap of cognate words modulate cognate acquisition and processing in developing and skilled readers?

Abstract

Very few studies exist on the role of cross-language similarities in cognate word acquisition. Here we sought to explore, for the first time, the interplay of orthography (O) and phonology (P) during the early stages of cognate word acquisition, looking at children and adults with the same level of foreign language proficiency, and by using two variants of the word-association learning paradigm (auditory learning method vs. auditory + written method). Eighty participants (forty children and forty adults, native speakers of European Portuguese [EP]), learned a set of EP-Catalan cognate words and non-cognate words. Among the cognate words, the degree of orthographic and phonological similarity was manipulated. Half of the children and adult participants learned the new words via an L2 auditory and written-L1 word association method, while the other half learned the same words only through an L2 auditoryL1 word association method. Both groups were tested in an auditory recognition task and a go/no-go lexical decision task. Results revealed a disadvantage for children in comparison to adults, which was reduced in the auditory learning method. Furthermore, there was an advantage for cognates relative to non-cognates regardless of the age of participants. Importantly, there were modulations in cognate word processing as a function of the degree of O and P overlap which were restricted to children. The findings are discussed in light of the most relevant bilingual models of word recognition.
