A lexical semantic approach to the L2 acquisition of Spanish psych verbs

This study builds on prior research on second language (L2) Spanish psych verbs, which has centered on morphosyntactic properties, by examining their syntactic distribution, which relies on lexical semantic knowledge. The fact that certain forms are licensed for some verbs, but not others, is the result of an underlying lexical semantic difference across verb classes, represented here as a difference in formal feature strength. To fully acquire the relevant grammatical distribution, L2 learners must successfully acquire (i) licensing restrictions on argument structure and (ii) underlying lexical semantic representations of individual verbs. Three groups of L2 learners (n = 66) and a group of native Spanish speakers (n = 19) completed two judgment tasks (one with aural stimuli and one with written stimuli) which presented object experiencer psych verbs in multiple argument structures. Results show that advanced L2 learners are largely sensitive to the distribution tested here; however, while they have acquired relevant licensing restrictions, they may associate fixed feature settings with verbs that allow variable feature settings. These results are consistent with predictions made by the Feature Reassembly Hypothesis and highlight the role of lexical semantic features in second language acquisition.
