Second language acquisition (SLA) researchers have long searched for patterning in the development of linguistic elements (e.g., grammar and morphology). However, little attention has been given to the examination of systematicity in vocabulary acquisition, limiting our understanding about how overall vocabulary is learnt. The current study…

The study investigates how the test modality (spoken or written) of classroom weekly quizzes influences vocabulary learning strategies and facilitates learning the spoken and written knowledge of form-meaning connection in L2 words. Japanese university students in academic English courses were assigned to two experimental conditions (spoken test…

Learning new words is fundamental in both first and second-language reading. There are, however, divided opinions on the best instructional approaches. Two widely used approaches across languages are whole-word focus and word-constituent focus. The appropriateness of each approach has varied historically, even within a single language (e.g., the…

Shifting demographics in K-12 schools have increased Spanish-speaking Multi-Language Learners' (MLLs') enrollment across the United States. While literacy variations between MLLs and proficient English speakers have been studied predominantly with upper elementary students, there remains a need for more exploration among early elementary…

Recent literature in the field of L2 vocabulary assessment has advocated for the development of written receptive vocabulary tests such as Vocabulary Levels Tests (VLTs) that use: (a) meaning-recall item formats, (b) a minimum of 40 item counts per 1,000-frequency band to improve level estimates, and (c) lemmas (not word-families) as the lexical…

The academic section of the Vocabulary Levels Test (VLT-Ac) and the Academic Vocabulary Test (AVT) both assess meaning-recognition knowledge of written receptive academic vocabulary, deemed central for engagement in academic activities. Depending on the purpose and context of the testing, either of the tests can be appropriate, but for research…

The study investigates the relationship between lexical encoding and production in order to establish whether learners are able to produce a difficult contrast in words that they merged in their mental lexicon. Forty American English learners of Russian were tested on their production and lexical encoding of familiar and highly-frequent words with…

The writing system -- the transparency of orthography in alphabet-based systems and differences between logographic and phonetic-based systems -- can affect the efficiency of inferential word learning when words are introduced visually. It can also shape how people self-evaluate their learning success (we refer to such type of self-evaluation as…

Background: Although most prevalent in childhood, the acquisition of new words in oral vocabulary takes place right across the lifespan. Of the many factors that influence oral vocabulary learning, one extrinsic factor is the listening environment. The current study aimed to examine whether the presence of noise impacts oral vocabulary learning in…

Research suggests new foreign language (FL) words are learned more easily if their phonology follows the phonotactic rules of the native language. Very little is known, however, about the impact of orthography on FL learning. This study investigated the cognitive mechanisms supporting the learning of words with familiar and unfamiliar…

This study explored the use of stealth assessments within a digital game to assess second language (L2) Chinese learners' reading comprehension. Log data tracking learners' in-game behaviors from a game designed for Chinese dual language immersion classrooms (Poole et al., 2022) were used to construct Bayesian Belief Networks to model reading…

This study aimed to investigate the effect of written cues on the second- language (L2) language perception, processing, and word learning, especially when the person's first language (L1) belongs to a different rhythmic type of language than L2. The first objective was to examine whether late bilinguals as L2 learners can benefit more from…

Age of acquisition (AoA) refers to the age at which people learn a particular item and the AoA effect refers to the phenomenon that early-acquired items are processed more quickly and accurately than those acquired later. Over several decades, the AoA effect has been investigated using neuroscientific, behavioral, corpus and computational…

While many elementary-level children in the United States still do not have access to a second/additional language (L2), an increasing number are educated via Foreign Language Exposure (FLEX) tracks. Our two-semester study examines elementary-level L2 learners' engagement, emerging L2 Spanish vocabulary use, and awareness of the arbitrary nature…

This study aims at specifying cultural words in teaching Turkish as a foreign language according to their proficiency levels (A1/2, B1/2, and C1/2) and analyzing the difference between the proficiency levels of these cultural words in terms of their frequency. For this purpose, a cultural corpus of 112.350 tokens in total has been created based on…
