"Taza" in Spanish refers to cups and mugs in English, whereas glass refers to different glass types in Spanish: "copa" and "vaso." It is still unclear whether such categorical distinctions induce early perceptual differences in speakers of different languages. In this study, for the first time, we report symmetrical…

Can brief training on novel grammatical morphemes influence visual processing of nonlinguistic stimuli? If so, how deep is this effect? Here, an experimental group learned two novel morphemes highlighting the familiar concept of transitivity in sentences; a control group was exposed to the same input but with the novel morphemes used…

Linguistic categories can impact visual perception. For instance, learning that two objects have different names can enhance their discriminability. Previous studies have identified a typical pattern of categorical perception, characterized by faster discrimination of stimuli from different categories, a neural mismatch response during early…

The comprehension of signed language requires linguistic and visual-spatial processing, such as perspective-taking for correctly interpreting the layout of a spatial scene. However, little is known about how adult second-language (L2) learners process visual-spatial constructions in a signed language that they are studying, including which angles…
