JELT_V6_N3_RevP1 John Paul O. Dela Rosa Diana C. Arguelles Journal on English Language Teaching 2249 – 0752 6 3 46 60 Foreigner Talk, Teacher Talk, FT Characteristics, FT Effects, Second Language Acquisition This critical review of literature provides a detailed description of foreigner talk as a simplified register and critically discusses findings entrenched in studies done about this SLA issue. The studies cited are classified as researches concerning foreigner talk that occurs in both natural and classroom settings. Based on the critical review, more research investigations have to be done to enrich the area of foreigner talk in second language acquisition and learning. The most important consideration is the need to conduct more researches that would validate both the positive and negative effects of foreigner talk in the process of acquiring and learning a second language as well as a foreign language like English. The emergence of significant concerns on the study of FT is also highlighted in this presentation which include how researchers regarded the effectiveness of both input modifications and interactional adjustments along with the occurrence of negotiation of meaning and the use of communication strategies in the SLA process. The paper also presents empirical data on the effectiveness of NNS-NNS interactions in second language learning in contrast with interactions occurring between Native Speakers (NSs) and Nonnative Ones (NNSs). Finally, the paper deals with what could be done to address the “inconclusiveness” of relevant research findings on foreigner talk. July - September 2016 Copyright © 2016 i-manager publications.
