EFFECTS OF LISTENERS' EXPECTATIONS OF SPEAKERS' NATIVENESS: IDENTIFICATION OF PHONEMIC VOWEL LENGTH

Abstract

Purpose of the study: This study is to describe an experiment in which native Arabic listeners identified phonemic vowels in Arabic words. Native Arabic speakers from a variety of dialects and non-native Arabic speakers spoke the words. The main objective of the present study is to understand the neglected role of the native listeners in making communication successful or impeded when native listeners lack adequate information about the non-native speaker and when the top-down processing is absent.
 Methodology: The present study examined real Arabic minimal pairs (short versus long vowels) uttered at a regular speaking rate by both native speakers of Arabic (NSA) as a control group and non-native speakers of Arabic (NNSA) as a test group. First, we told the listeners that they would hear speakers from various countries, and we did not tell them that the stimuli had non-native words. In the subsequent part of the experiment, we told native listeners that they would hear both native speakers and non-native intermediate speakers.
 Main Findings: The major outcome of the present study is that listeners made slower and less correct identifications when they knew that some of the speakers were non-native. The finding of the experiment confirms the hypothesis that the processing of non-native productions is influenced by native listeners' negative expectations about non-native speakers with the absence of adequate facilitating details.
 Applications of this study: The study contributes to the psycholinguistic understanding of the role of the native listeners' expectations and attitudes towards non-native speakers and contributes to the understanding of the interaction between native listeners and non-native speakers. The study can help linguists in understanding the role of listeners in communication impediments within the top-down approach.
 Novelty/Originality of this study: This work adopts a new approach where we tested the same listeners twice, first with no information about non-native speakers and second with information that they will hear non-native speakers in the stimuli. Such an approach intends to improve our perception towards language communication within listeners' attitudes as associated with foreign speakers when information about the context of stimuli is inadequate.
