Phonological parsing via an integrated I-language

Schwartz and Sprouse (2021) argue against property-by-property Transfer (Westergaard, 2021a, b) and for wholesale transfer (Rothman, 2015) into a third language grammar by questioning the cognitive plausibility of “extracting a proper subpart from the … grammar and using that proper sub-system as the basis for a new cognitive state.” I will argue that the insights from the approaches of López (2020); Lightfoot (2020); Dresher (2018), and Westergaard (2021a) when applied to empirical data from L3 English data from L1 Arabic/L2 French speakers, give us reason to question Schwartz and Sprouse’s defence of wholesale transfer, and its typological underpinnings. We can set the study of L3A in a larger context which can unify domains such as the acquisition of phonology and syntax via a unified approach to parsing. By invoking an underspecified, minimal UG, primary linguistic data, and domain-general third factors which act in concert to parse the E-language to select structures, we can capture the underlying similarity of first, second, and third language acquisition. Parsing proceeds in an error-driven fashion, structure by structure, drawing on the Integrated I-language and UG options found in a Repository. In essence, this approach renders the wholesale/property-by-property distinction a false dichotomy.
