L2 cognitive construal and morphosyntactic acquisition of pseudo-passive constructions

Abstract Discussion of the theoretical underpinning of pseudo-passive constructions abounds in generative linguistics and comparative typology. However, the cognitive construal of and morphosyntactic acquisition of (un)grammatical English pseudo-passive constructions by Chinese-speaking L2-English users with different proficiency levels have never been investigated. It is worth examining whether proficiency level modulates constructional acceptability and cognitive construal, which would allow us to infer L2-English users’ morphosyntactic acquisition stages of pseudo-passive constructions. To fill this research gap, the study recruited 120 L2-English speakers with different levels of proficiency and 40 native English speakers to complete a grammaticality judgment test with an acceptance judgment scale from −2 to 2 for 40 ungrammatical pseudo-passive sentences and 40 fillers. Proficiency level significantly correlates with a firmer rejection of ungrammatical pseudo-passive sentences and cognitive construal which is more target-like. Significantly asymmetrical acceptance levels between two types of target ungrammatical constructions are also revealed for low ( p = 0.002) and medium proficiency ( p = 0.000) groups, demonstrating the type effect on grammaticality judgment and morphosyntactic acquisition.
