The Takeaway
Because English and Mandarin grammar emphasize different parts of an action (the start vs. the result), native speakers actually perceive the same video differently. English speakers are faster to notice glitches at the very beginning of a task, while Mandarin speakers are significantly more eagle-eyed at the very end.
From the abstract
Languages differ in how they encode object–state changes, which in turn can influence how speakers segment dynamic events. English and Mandarin diverge at the lexical level in their use of determiners and verb-satellite constructions, and at the phrasal level in how they represent telicity. This study examined whether such lexical and phrasal differences modulate two types of event segmentation: internal segmentation (detecting interruptions within an unfolding event) and external segmentation (
