The purpose of the present study was to compare differential functioning of Iranian English versus Persian teachers in responding to compliments and to investigate the possibility of sociolinguistic transmission of speech act of responding to compliments from English culture to native Iranian Persian speakers. Following Chen and Yang (2010), we hypothesized that exposure to English would affect the complimenting behavior of Persian speakers, leading to more acceptance of compliments compared to those with little or no exposure to English. Participants of (...) the study were 50 English teachers, regarded as “exposed-to-English” or E group, and 50 Persian teachers, considered as “unexposed-to-English” or U group. The participants’ age ranged from 20 to 35 and they were selected through non-randomized convenience sampling. A Discourse Completion Test (DCT) comprising eight complimenting situations was developed in two versions, i.e. English and Persian, in light of Mane’s (1983) taxonomy. The results revealed a significant difference in performance between groups and that Iranian English teachers’ Compliment Response (CR) behavior changed due to exposure to English and approached English culture. Further findings and implications are discussed in the paper. (shrink)
