Understanding speech in an accent or dialect different than one's own can be challenging. McLaughlin and Van Engen (2020) were the first to quantify this increase in listening effort using Task Evoked Pupillary Response (TEPR), a common measure of cognitive arousal. They found that monolingual, English speaking adults' pupils dilated more quickly…

To become a native speaker, beyond obligatory rules, children need to learn systematic variation in the language, as it is present at all levels of language structure and is an integral part of linguistic knowledge. To give an example in English, speakers sometimes pronounce words ending in -ing with -in' (e.g., working vs. workin') depending on…

Purpose: The purpose of this study was to examine whether oral bilingualism could be an advantage for children with hearing loss when learning new words. Method: Twenty monolingual and 13 bilingual children with hearing loss were compared with each other and with 20 monolingual and 20 bilingual children with normal hearing on receptive vocabulary…

Purpose: Implicit statistical learning in 2 nonlinguistic domains (visual and auditory) was used to investigate (a) whether linguistic experience influences the underlying learning mechanism and (b) whether there are modality constraints in predicting implicit statistical learning with age and language skills. Method: Implicit statistical learning…

Purpose: To examine the impact of language background and language-related disorders (LRDs--dyslexia and/or language impairment) on performance in English speech and nonspeech tests of auditory processing (AP) commonly used in the clinic. Method: A clinical database concerning 133 multilingual children (mostly with English as an additional…

Purpose: In this study, the authors aimed to investigate how differences in language ability relate to differences in processing talker information in the native language and an unfamiliar language by comparing performance for different ages and for groups with impaired language. Method: Three groups of native English listeners with typical…

This study explored the developmental trends and phonetic category formation in bilingual children and adults. Participants included 30 fluent Spanish-English bilingual children, aged 8-11, and bilingual adults, aged 18-40. All completed gating tasks that incorporated code-mixed Spanish-English stimuli. There were significant differences in…

The Phonological Permeability Hypothesis (PPH, Cabrelli Amaro & Rothman, 2010) attempts to reconcile evidence suggesting some L2 learners, however rare, attain native-like L2 phonological systems with the observation that most do not. Considering existing L2 phonology research, it is not clear that phonological differences between early and…

Many studies have shown that French Cued Speech (CS) can enhance lipreading and the development of phonological awareness and literacy in deaf children but, as yet, there is little evidence that these findings can be generalized to English CS. This study investigated the possible effects of English CS on the speech perception, phonological…

Speech-language pathologists (SLPs) rely on knowledge of tongue placement to assess and provide intervention. A total of 175 SLPs who worked with children with speech sound disorders (SSDs) drew coronal diagrams of tongue/palate contact for 24 English consonants. Comparisons were made between their responses and typical English-speaking adults'…

Purpose: Recent studies from the authors' laboratory have suggested that reduced audibility in the high frequencies (because of the bandwidth of hearing instruments) may play a role in the delays in phonological development often exhibited by children with hearing impairment. The goal of the current study was to extend previous findings on the…

The McGurk effect paradigm was used to examine the developmental onset of inter-language differences between Japanese and English in auditory-visual speech perception. Participants were asked to identify syllables in audiovisual (with congruent or discrepant auditory and visual components), audio-only, and video-only presentations at various…

One of a regular series on the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications, this report covers the period of January 1-June 30, 1984. The 14 studies summarized in the report deal with the following topics: (1) sources of variability in early speech development, (2)…

Papers from three conferences on applied linguistics include the following: "Evaluating Language Success in an Irish Context" (D. P. O Baoill); "Facilitation of Language Development in the Deaf Child" (M. Nicholas Griffey, Sr.); "Observations on Thematic Interference Between Irish and English" (M. Filppula); "A…
