Investigating word class effects in first and second languages

According to Zyzik in 2009, only a few recent studies have investigated similarities in use of words in comprehension of first languages (L1) and second languages (L2). Furtner, Rauthmann, and Sachse showed a rank order of word classes by frequency of eye-gaze regression when reading other difficult words: nouns, adjectives, closed-class words, verbs. The hypothesis was that a L1-L2 word-class similarity effect between German (L1) and English (L2) would occur, and this was tested with jumbled word reading of English text (wherein letters within words Shave been jumbled) and eye-tracking by 141 participants. Analyses of regressive fixations from one word class to others showed that nouns were regressed most often and there was a rank order of importance among the word classes apparently used to enhance comprehension of other difficult words (nouns, adjectives, verbs, dosed-class words). Thus, previous findings for L1 were largely replicated. Findings are discussed regarding language acquisition.
