The current study explores variation in phonemic representation among Spanish--English dual language learners (DLLs, n = 60) who were dominant in English or in Spanish. Children were given a phonetic discrimination task with speech sounds that: 1) occur in English and Spanish, 2) are exclusive to English, and 3) are exclusive to Russian, during…

When acquiring a second language, learners must become able to perceive the difference between novel sounds ("discrimination") and also associate strings of sounds with distinct vocabulary items ("lexical encoding"). Recent research has questioned whether discrimination is a sufficient or necessary condition for encoding, and…

The acquisition of a second language (L2) may be challenging in adulthood, as the phonological system of the native language (L1) can sometimes limit the perception of phonological contrasts in L2. The present study aimed to (a) examine the influence of an L1 (Hebrew) that lacks a phonemic contrast for vowel length on the ability to discriminate…

Shadowing, a practice of repeating what one hears as simultaneously and accurately as possible, has been researched in the Teaching English to Speakers of Other Languages (TESOL) field for years. The research findings have shown that shadowing contributes to English as a Foreign Language (EFL) learners' bottom-up listening skills, which leads to…

The purpose of this study was to investigate the effects of using an iPad to teach early literacy skills to students with intellectual disability (ID). Three elementary students with mild to moderate levels of ID participated in the study. We used a multiple-probe design across students to examine a functional relationship between using an iPad…

This study longitudinally examined the effects of cognitive and sociopsychological individual differences (aptitude, motivation, personality) and the quantity and quality of second language (L2) experience on L2 speech gains in naturalistic settings. We elicited L2 spontaneous speech from 50 Chinese learners of English at the beginning and the end…

Some listeners exhibit higher sensitivity to subphonemic acoustic differences (i.e., higher speech gradiency). Here, we asked whether higher gradiency in a listener's first language (L1) facilitates foreign language learning and explored the possible sources of individual differences in L1 gradiency. To address these questions, we tested 164…

Urdu language is a member of Indo-European family tree and within the zone of Indo-Iranian branch, whereas Turkish language is a member of Altaic family tree. Both of these languages belong to different family trees, but these languages have many words in common. Urdu language has 41 consonant sounds and 11 vowel sounds, whereas Turkish language…

Purpose: An important skill in the development of speech perception is to apply optimal weights to acoustic cues so that phonemic information is recovered from speech with minimum effort. Here, we investigated the development of acoustic cue weighting of amplitude rise time (ART) and formant rise time (FRT) cues in children as measured by mismatch…

Children with autism spectrum disorders have been reported to be less influenced by a speaker's face during speech perception than those with typically development. To more closely examine these reported differences, a novel visual phonemic restoration paradigm was used to assess neural signatures (event-related potentials [ERPs]) of audiovisual…

This study compared Spanish-English bilinguals' and English monolinguals' VOT values for /b, d, g/ in cognates and non-cognates. Twenty-six young adult participants (fourteen bilinguals and twelve monolinguals, mean age 24 years) were administered a picture-naming task, balanced for cognate and non-cognate forms. VOT values of 30 target words per…

Purpose: We empirically assessed the results of computational optimization and prediction in communication interfaces that were designed to allow individuals with severe motor speech disorders to select phonemes and generate speech output. Method: Interface layouts were either random or optimized, in which phoneme targets that were likely to be…

Mandarin has been added to the list of second additional languages (SAL) that South African learners can choose from. The researchers proactively conducted research pertaining to SAL (Mandarin) since it is a dynamic phenomenon in South Africa. The research question was formulated as follows: "Do factors such as 1) phonemic differences between…

Purpose: The aim of this study was to explore when and how Mandarin-speaking children use contextual cues to normalize speech variability in perceiving lexical tones. Two different cognitive mechanisms underlying speech normalization (lower level acoustic normalization and higher level acoustic-phonemic normalization) were investigated through the…

Early conceptions of aptitude were concerned with explicit learning abilities in formal learning settings, which according to MLAT (Modern Language Aptitude Test) were measurable based on a phonemic coding ability, an inductive learning ability, an associative memory, and a grammatical sensitivity (Carroll, 1962). However, recent understanding on…
