When classifying motion events, speakers classify motion in language-specific ways. In
the following study, we asked whether bilingual speakers shift their event classification
preferences based on the language in which they verbally encoded those events. Polish-English
bilinguals, English-Polish bilinguals, and English monolinguals described events in either Polish
or English. Additionally, they judged the similarity of motion events in a triad task. Participants
who performed the task in English mentioned manner more often in their verbal responses than
Polish participants. In the similarity judgement task, judgement was modulated in bilinguals by
the age of acquisition of the second language. The younger age English was acquired, the more
the participants were likely to judge similarity based on manner
