The use of gender-fair language (GFL) is intended to linguistically include persons of all genders. Over the last years, the gender colon has rapidly gained popularity in German (Waldendorf, 2024). It is similar to the gender star, but, instead of an asterisk, a colon is inserted between the masculine form/word stem and the feminine suffix -in (e.g., Student:in - student). The aim of both forms is to make persons identifying as nonbinary typographically visible. By now, several studies have investigated mental representations elicited by the star (e.g., Körner et al. 2022, Zacharski & Ferstl 2023). Until now, however, it was unclear whether the colon evoked the intended inclusive interpretation. In an online experiment, 108 students completed a word-picture matching task developed by Zacharski & Ferstl (2023). Participants saw singular role nouns in colon, feminine, or masculine form. After each word, they were presented with a picture of a person read as nonbinary, female, or male. They had to decide whether the image was a suitable visualization of the presented word. Replicating previous findings, masculine forms evoked a male bias in mental representations. Interestingly, this effect was particularly strong for participants who held a positive attitude towards GFL. This suggests an enhanced male-specific interpretation in persons with a higher sensitivity towards gender discrimination. The gender colon, in contrast, was more appropriate than the masculine as a gender-inclusive form. However, a slight female bias was found in acceptance rates. Future research is needed to replicate this finding in more diverse samples.
