An ERP-based comparison of gender representations elicited by generic masculine role nouns and the German gender star form

There is an ongoing debate about the linguistic gender forms that should be used to elicit fair mental representations of all genders. While most languages with grammatical gender traditionally use the masculine form to refer to people in a gender-independent way, numerous empirical studies have demonstrated that this form leads to a male bias in mental representations. In German, the so-called gender star form has been proposed as an alternative to the masculine form, aimed at better representing persons with nonmale gender identities. To provide empirical data on this claim, we compared the neural processing mechanisms elicited by the gender star form with those elicited by the generically intended masculine form during reference resolution. Participants in the present ERP study read sentence pairs in which a group of people was introduced with a role noun in one of the two gender forms and then revealed to be partly comprised of men or women. Following the masculine form, anaphoric references to women (vs. men) resulted in an increased ERP amplitude in the P600 range. In contrast, following the gender star form, the P600 amplitude was increased for references to men (vs. women), albeit in a slightly different spatio-temporal range. The present data thus indicate that the gender star form and the generically intended masculine form impose partially different demands on the syntactic operations performed by the brain during reference resolution but that, in the end, neither form elicits gender-balanced mental representations of men and women in German.
