Processing of grammatical gender agreement morphemes in Polish: evidence from the Visual World Paradigm

Abstract This paper presents a psycholinguistic study of the processing of grammatical gender agreement morphemes in Polish, which has three gender categories (masculine, feminine, neuter), as well as what language-internal factors impact this processing. Results from an eye-tracking study using the Visual World Paradigm show that, during real-time language comprehension, adult monolingual speakers of Polish use cues from gender agreement on a prenominal adjective to anticipate the upcoming noun. An exploration of language-internal factors affecting this anticipatory processing finds this effect in all three genders, suggesting that encountering the relevant nominative-case agreement morpheme during language comprehension leads to automatic activation of a gender node in the mental lexicon, consistent with the literature on other languages with grammatical gender. These results hold true for the neuter agreement morpheme, despite the fact that this morpheme also instantiates default gender agreement in the language and is syncretic with the nominative plural agreement morpheme in all three genders. Further investigation finds that, while agreement morphemes for each gender prompt anticipatory processing, the reliability of a masculine agreement morpheme as a cue to gender is reduced in the presence of a neuter distractor, and vice versa. This raises questions regarding phonological proximity between the realized suffix and the suffix that would cue the distractor, with implications for the acquisition and processing of gender agreement morphology in Polish.
