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…

Purpose: Vocabulary skills in children are typically measured with norm-referenced assessments of receptive and expressive vocabulary. Language sample analysis is an alternative method of examining vocabulary actually produced in communicative events and may be better suited to exposing subtle vocabulary weaknesses. Here, we examine the…

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 examines the effects of the continuation task and the model-as-feedback writing task (MAFW) on English as a foreign language (EFL) vocabulary learning. Three classes of intermediate-level Chinese EFL learners were randomly assigned to a continuation group, a MAFW group, and a control group. Three aspects of vocabulary knowledge --…

There are few published estimates of vocabulary sizes amongst students in tertiary education. Research does not offer estimates of the vocabulary size tertiary students might be expected to possess, though estimates exist for K-12 education, some EFL contexts, and the general population. Such research is important. For reading comprehension during…

This study investigated the relationships between two vocabulary learning strategies (guessing from context and dictionary use) and two aspects of vocabulary knowledge (receptive and productive vocabulary knowledge). One hundred and thirty-five university students in Japan completed a vocabulary learning strategies survey, the Updated Vocabulary…

Background: Differentiating typical language development (TD) and developmental language disorder (DLD) in a bilingual context is difficult. The societal language is often the only mutual language of the child and the SLT. It has been shown that when assessing second language (L2) performance using tools developed for monolingual children,…

We tested the utility of two standardized measures of receptive skills in American Sign Language (ASL) in hearing adults who are novice signers: the ASL Comprehension Test (ASL-CT; Hauser, P. C., Paludneviciene, R., Riddle, W., Kurz, K. B., Emmorey, K., & Contreras, J. (2016). American Sign Language Comprehension Test: A tool for sign language…

In second language (L2) vocabulary studies there is continuing interest in tests of depth of vocabulary knowledge, measuring various aspects of word knowledge other than just the form--meaning link that is the focus of breadth (or size) tests. This study aimed to explore new formats that could be used as diagnostic tools for assessing depth of…

Background: Standardised Mandarin assessment tools for examining difficulties in language comprehension and expression at different developmental stages are limited in China. The first comprehensive standardised Mandarin assessment tool is the Diagnostic Receptive and Expressive Assessment of Mandarin-Comprehensive (DREAM-C), which is normed for…

The thrust of this study was to investigate the impact of learning styles in general and Field dependence/Independence (FD/I) in particular on the receptive/productive lexical performance of language learners. It aimed to check whether FD/I learners perform differently on receptive and productive vocabulary tests. To achieve this, first, 94…

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,…

This study compared the effects of task repetition only (TR), task repetition with grammatizing (TR+GR), and grammatization with no task repetition (GR) on 94 EFL learners' oral task performances. Participants' productions were measured both in terms of complexity, accuracy, and fluency as well as receptive knowledge (measured by an error…

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…

Two commonly used test types to assess vocabulary knowledge for the purpose of reading are size and levels tests. This article first reviews several frequently stated purposes of such tests (e.g., materials selection, tracking vocabulary growth) and provides a reasoned argument for the precision needed to serve such purposes. Then three sources of…
