Korean honorific system itself serves as a natural prime for regulatory orientation given that the context of deferential (informal) communication reflects the setting for a prevention (promotion) focus. As a result, advertisements written in an informal, deferential tone are more likely to be deemed appropriate for use with utilitarian (hedonistic) goods.
