The fluency task, which involves lexical retrieval from a categorical or thematic prompt, has been a crucial paradigm in studies about lexicon in bilingualism and additional languages. Particularly, there has been a very productive cognitive turn towards analytical models based on the exploration of the cognitive processes underlying the mental…

Background: Children who stutter have the right to express their views and be heard. However, in research on stuttering, attention tends to focus mainly on parental and adult perspectives. By actively engaging with children's viewpoints, we can enhance our understanding of their distinct needs and capabilities. This, in turn, enables the…

Purpose: The dual-task paradigm has been frequently used to examine stroke-related deficits because it samples behavioral performance under conditions of distraction similar to functioning in real-life environments. This original systematic review synthesizes studies that examined dual-task effects involving spoken language production in adults…

Complexity, accuracy, and fluency (CAF) as measures of language proficiency have been used extensively in assessing second language production in English language studies related to task-based language teaching. The present review adds the following critical elements to the existing body of literature: (i) Provides synthesis and critical analysis…

Increased second language acquisition (SLA) research interest in the effect of planning on subsequent L2 oral production has typically examined the effect of planning on the syntactic complexity, accuracy, lexical complexity, and/or fluency (CALF) of L2 production. However, the results of research in this domain are inconclusive. This study, a…

From 2016 to 2022, the "Journal of Applied Behavior Analysis" published 7 studies that evaluated the effects of habit reversal training on speech disfluencies (filled pauses) during public speaking. This review summarizes the participants, dependent variables, procedures, experimental design, and outcomes from this research including…

While task repetition is effective for improving oral fluency, some teachers are reluctant to use it in their classrooms due to the alleged negative perceptions of learners toward repetitive practice. To address this concern, the participants in the current study completed a posttask questionnaire probing their perceptions toward task repetition…

Background: Adults with intellectual disability, especially those with Down syndrome, are at increased risk of dementia. Whilst memory decline is often considered the earliest symptom, emerging research indicates decline in language, executive function, and non-cognitive domains may also occur early, potentially before memory changes. Method: A…

This systematic review aims to explore how task complexity and task sequencing affect the complexity, accuracy, and fluency (CAF) of second language performance. Through an analysis of studies conducted between 2012 and 2021, this review investigates the characteristics of the studies, operationalisation of task complexity, measurements of CAF,…

Educational speaking technology is a digital expertise used to enhance speaking performance. This research examined the effects of using educational speaking technology tools: FORVO, YouGlish, and OALD 8th ed. to enhance students' speaking performance. A quasi-experimental pretest-posttest two groups design was used. Test, questionnaire,…

Listener-based judgements of fluency play an important role in second language (L2) communication contexts and in L2 assessment. Accordingly, our meta-analysis examined the relationship between different aspects of utterance fluency and listener-based judgements of perceived fluency by analyzing primary studies reporting correlation coefficients…

Background/purpose: A significant challenge in teaching Arabic at the secondary level is developing pronunciation, fluency, and communication. Despite increased use of digital tools in instruction, a gap remains in understanding their effectiveness in improving Arabic speaking skills. This article aims to identify the types of digital teaching…

Purpose: This scoping review considers the acoustic features of a clear speech register directed to nonnative listeners known as foreigner-directed speech (FDS). We identify vowel hyperarticulation and low speech rate as the most representative acoustic features of FDS; other features, including wide pitch range and high intensity, are still under…

Purpose: This systematic review focuses on the effect of bilateral deep brain stimulation (DBS) of the subthalamic nucleus (STN) on language function in Parkinson's disease (PD). It fills an important gap in recent reviews by considering other language tasks in addition to verbal fluency. Method: We critically and systematically reviewed the…

Ascertaining the value of a study abroad experience on facilitating language development has long been a goal of Second Language Acquisition scholars. There is currently a plethora of studies regarding the topic, yet, despite this, the evidence remains inconclusive and contradictory. This systematic review evaluates the impact of study abroad…
