The conceptualization of time differs between English and Mandarin Chinese speakers, impacting their cognitive processing. English speakers predominantly use horizontal metaphors for time, such as "I'm running behind schedule." Mandarin Chinese speakers, however, use both horizontal and vertical metaphors, where the past can be described as "up" and the future as "down." This linguistic difference translates to performance on cognitive tests; when primed with vertical cues, Mandarin speakers recognize temporal relationships between months more quickly, demonstrating how language can shape abstract thought.
