Background: The evidence on the effect of age on the receptive and expressive language skills of individuals with Down syndrome is inconclusive. Recent research highlights the relevance of having tools to detect age-related changes in language skills. Method: Data were collected on 45 adults with Down syndrome. All were assessed with the Peabody…

EL1 learners' receptive morphological words (root, inflected, and derived words) develop on different scales, but whether they develop similarly in EFL learners' language production is still unknown and deserves an examination. The answer may provide a clue to theoretical controversy about whether language learners' morphologically defined words…

Although research shows that second language (L2) learners have major difficulties in developing their productive vocabulary skills, little research has been conducted on how to facilitate productive mastery of learned words. With this in mind, this study investigated the effects of task type and repetition frequency on improving receptive word…

The purpose of this study was to examine the effectiveness of explicit corrective feedback (CF) strategies (i.e., metalinguistic feedback and explicit correction) versus implicit CF methods (i.e., recasts and explanation questions) in helping English language learners acquire the that-trace filter. To this end, one hundred twenty intermediate…

Autism Spectrum Disorder (ASD) and epilepsy represent a comorbidity that negatively influences the proper development of linguistic competencies, particularly in receptive language, in the pediatric population. This group displays impairments in the auditory comprehension of both simple and complex grammatical structures, significantly limiting…

This study investigated how much practice is necessary for learners to attain durable second language (L2) grammar knowledge. Using digital flashcards, 119 participants practiced translating 12 sentences into an artificial language, followed by feedback, until they had typed all sentences correctly. Participants repeated this activity in one, two,…

Recently, research in second language acquisition has seen an increased attention on low-educated low-literate (LESLLA) learners. However, few of the existing instruments to measure L2 proficiency have been validated for use with this population. In this paper, we examine how adult L2 learners with diverging educational backgrounds perform on and…

In English as a lingua franca (ELF) communication, in which English is used as a common language among interlocutors of different first languages, successful communication often features communication strategies that enhance mutual understanding and relationship management. Although prior research suggests that including such strategies in English…

Vocabulary acquisition is a fundamental element of mastering the English language, necessitating a comprehensive lexicon that evolves through experiential learning to facilitate accurate comprehension and production of language. The current study examined the impact of Total Physical Response (TPR) tasks on the vocabulary acquisition of Thai…

This paper examined to what extent causal explanation speaking tasks (CESTs) are cognitively appropriate for assessing young language learners' (YLLs) L2 speaking. Ninety-six YLLs (48 from Grade 4 and 6 each) in China performed two CESTs in both L1 (Chinese) and L2 (English). They also completed receptive and productive L2 vocabulary size tests.…

Research on the implementation of CLIL at the onset of primary school is limited and has largely overlooked the role of other sources of individual differences. This study investigated the effects of the CLIL approach to English learning, together with the effects of out-of-school exposure to the language through media and other sources of…

Previous studies on lexical focus on form (FonF) have mostly centred on FonF in reading with a few pre-selected lexical items. This study investigated the contribution of oral incidental FonF to developing learners' lexical knowledge in a free discussion EFL class. Incidental FonF was provided to 15 upper-intermediate learners who participated in…

Background and Aims: This longitudinal study investigated the language skills, phonological working memory and lexical-tone perception of Mandarin-speaking late-talkers (LTs) and those with typical language development (TLD) at 27 months, while also examining their connections with novel word-referent mapping (W-R mapping) through eye-tracking at…

Self-assessment is an alternative assessment that can assess one's language ability, and it has been widely used, especially in classroom contexts. However, recent research has suggested different results regarding the correlation between student self-assessment and language performance. The accuracy of student assessment depends on various…

This study examines the role of receptive vocabulary knowledge on outcomes of the TOEFL reading comprehension task. Participants included 18 native speakers of Spanish learning English as a foreign language and 17 native speakers of English ranging in age from 19-25 years. Lexical stimuli were presented auditorily and were divided into…
