Phonological Feature Abstraction Before 6 Months: Amodal Recognition of Place of Articulation Across Multiple Consonants Open
The classical view is that perceptual attunement to the native language, which emerges by 6–10 months, developmentally precedes phonological feature abstraction abilities. That assumption is challenged by findings from adults adopted into …

Maternal input, not transient elevated depression and anxiety symptoms, predicts 2-year-olds’ vocabulary development Open
Both the quantity and quality of the maternal language input are important for early language development. However, depression and anxiety can negatively impact mothers’ engagement with their infants and their infants’ expressive language …

The development of tone discrimination in infancy: Evidence from a cross‐linguistic, multi‐lab report Open
We report the findings of a multi‐language and multi‐lab investigation of young infants’ ability to discriminate lexical tones as a function of their native language, age and language experience, as well as of tone properties. Given the hi…

Does Musicality Assist Foreign Language Learning? Perception and Production of Thai Vowels, Consonants and Lexical Tones by Musicians and Non-Musicians Open
The music and spoken language domains share acoustic properties such as fundamental frequency (f0, perceived as pitch), duration, resonance frequencies, and intensity. In speech, the acoustic properties form an essential part in differenti…

Effects of maternal depression on maternal responsiveness and infants’ expressive language abilities Open
High levels of maternal responsiveness are associated with healthy cognitive and emotional development in infants. However, depression and anxiety can negatively impact individual mothers’ responsiveness levels and infants’ expressive lang…

Impaired neural entrainment to low frequency amplitude modulations in English-speaking children with dyslexia or dyslexia and DLD Open
Neural synchronization to amplitude-modulated noise at three frequencies (2 Hz, 5 Hz, 8 Hz) thought to be important for syllable perception was investigated in English-speaking school-aged children. The theoretically-important delta-band (…

Infants show enhanced neural responses to musical meter frequencies beyond low‐level features Open
Music listening often entails spontaneous perception and body movement to a periodic pulse‐like meter. There is increasing evidence that this cross‐cultural ability relates to neural processes that selectively enhance metric periodicities,…

Atypical cortical encoding of speech identifies children with Dyslexia versus Developmental Language Disorder Open
Slow cortical oscillations play a crucial role in processing the speech envelope, which is perceived atypically by children with Developmental Language Disorder (DLD) and developmental dyslexia. Here we use electroencephalography (EEG) and…

Seeing a talking face matters: Infants' segmentation of continuous auditory‐visual speech Open
Visual speech cues from a speaker's talking face aid speech segmentation in adults, but despite the importance of speech segmentation in language acquisition, little is known about the possible influence of visual speech on infants' speech…

Language specificity in cortical tracking of speech rhythm at the mora, syllable, and foot levels Open
Recent research shows that adults’ neural oscillations track the rhythm of the speech signal. However, the extent to which this tracking is driven by the acoustics of the signal, or by language-specific processing remains unknown. Here adu…

Seeing a talking face matters: The relationship between cortical tracking of continuous auditory‐visual speech and gaze behaviour in infants, children and adults Open
An auditory-visual speech benefit, the benefit that visual speech cues bring to auditory speech perception, is experienced from early on in infancy and continues to be experienced to an increasing degree with age. While there is both behav…

The tone atlas of perceptual discriminability and perceptual distance: Four tone languages and five language groups Open
Some prior investigations suggest that tone perception is flexible, reasonably independent of native phonology, whereas others suggest it is constrained by native phonology. We address this issue in a systematic and comprehensive investiga…
