German in childhood and Latin in adolescence: On the bidialectal nature of lexical access in English
The nature of word etymology, long a topic of interest in linguistics, has been considered to a much lesser extent in the word recognition literature. The present study created a database of overlapping words from the English Lexicon Project and a database with age of acquisition (AoA) norms which were categorized as either Germanic or Latin-based. Results revealed that Germanic words were learned earlier than Latin-based words. Germanic words also showed lower reaction times and higher accuracy relative to Latin-based words even when controlling for AoA, word frequency and length. The findings support a bidialectal view of English in that Germanic words serve as the base of lexical processing during childhood, whereas Latin-based words fill in the lexical space across adolescence and into early adulthood. These results carry implications for theories of word recognition and the processing of lexical items in populations that come from linguistically diverse backgrounds.
