The majority of studies on compliment response (CR) have investigated CR patterns and norms among different cultural groups and communities. The present study investigated the shifting of CR patterns across generations within the same speech community. To this end, 272 Persian speakers were chosen from among high school students and teachers. A discourse completion task (DCT) with four complimenting situations was administered. The findings revealed that the new generation of Persian speakers, regardless of their gender, had shifted their CR patterns and overwhelmingly accepted compliments. This change is attributed to the changing interpretations and conceptions of politeness and to the influx of English culture, through exposure to English media, internet, TV series, films, etc., among the new generation of Persian speakers.
