According to representational accounts (Hawkins & Franceschina, 2004), the inability to acquire abstract syntactic features after a critical period explains L2 difficulties with gender, while according to lexical accounts (Grüter et al. 2012; Hopp 2012), gender assignment issues – the inability to assigned to a target-like class accounts for these difficulties. We explore three potential agreement cues: 1) semantic gender relating to sex (e.g. ‘girl’ vs. ‘boy’) 2) morphophonological transparency cues, and 3) syntactic agreement cues. Semantic and morphophonological cues may facilitate gender agreement only for a subset of nouns, whereas agreement cues can do so for all nouns, including opaque gender nouns that do not have semantic gender.
Seventeen low proficiency and sixteen high proficiency L1 English L2 Spanish speakers and seventeen native Spanish controls judged the grammaticality of 60 experimental sentences. We compared participants’ gender agreement accuracy and reaction times (RTs) on experimental items with and without semantic gender, and with and without transparent gender morphemes. Semantic gender did not serve as a cue for gender assignment/agreement; instead, it slowed down RTs in high proficiency and control participants. Morphophonological cues significantly increased accuracy and decreased RTs in all groups. Finally, agreement cues did not seem to help low proficiency learners, since their accuracy on opaque nouns was barely above chance. This suggests that they did not effectively use agreement cues to assign gender. By contrast, high proficiency learners exhibited native-like accuracy on opaque nouns. These findings support the lexical accounts of gender agreement difficulties, against the representational accounts.
