Grammatical gender form influences readers’ mental gender representations. Previous research demonstrates that the generic masculine form leads to male-biased representations, while some alternative forms lead to female-biased representations. The present research examines the recently introduced glottal stop form in spoken language in German, where a glottal stop (similar to a short pause), meant to represent all gender identities, is inserted before the gender-specific ending. In two experiments (total N = 1188), participants listened to sentences in the glottal stop, the generic masculine, or the generic feminine form and classified whether a second sentence about women or men was a sensible continuation. The generic feminine and the glottal stop led to female biases (fewer errors in sentences about women vs. men) and the generic masculine led to a male bias. The biases were smaller for the glottal stop and the generic masculine than for the generic feminine, indicating that the former two are more readily understood as representing both women and men.
