Nonverbal behavior can impact language proficiency scores in speaking tests, but there is little empirical information of the size or consistency of its effects or whether language proficiency may be a moderating variable. In this study, 100 novice raters watched and scored 30 recordings of test takers taking an international, high stakes…

The current paper examined the impact of Dynamic Assessment (DA) on the speaking skills of EFL learners applying socio-cultural theory, which was developed by Vygotsky (1934). The study also tried to compare the results from online synchronous DA sessions, which were done in the form of one-to-one online training over Google Meet, with the results…

The literature on task planning abounds with studies in laboratory or classroom contexts; however, the contribution of task planning to the testing context has remained a largely uncharted area of enquiry. The current study is primarily focused on exploring the impacts of pressured vs. unpressured on-line task planning conditions on EFL students'…

This study critically examined the previously reported partial independence between second language (L2) accentedness (degree to which L2 speech differs from the target variety) and comprehensibility (ease of understanding). In prior work, comprehensibility was linked to multiple linguistic dimensions of L2 speech (phonology, fuency, lexis,…

The current study investigated task effects on listener perception of second language (L2) comprehensibility (ease of understanding). Sixty university-level adult speakers of English from 4 first language (L1) backgrounds (Chinese, Romance, Hindi, Farsi), with 15 speakers per group, were recorded performing 2 tasks (IELTS long-turn speaking task…

Comprehensibility, a major concept in second language (L2) pronunciation research that denotes listeners' perceptions of how easily they understand L2 speech, is central to interlocutors' communicative success in real-world contexts. Although comprehensibility has been modeled in several L2 oral proficiency scales--for example, the Test of English…
