Although extensive research has focused on the perceptual abilities of second language (L2) learners, a significant gap persists in understanding how cognitive functions like phonological short-term memory (PSTM) and nonverbal intelligence (IQ) impact L2 speech perception. This study sets out to investigate the discrimination of L2 English…

Background: Virtual reality (VR) is considered a promising approach to support learning. An instructional design is essential to optimize cognitive processes. Studies show that VR has unique instructional and pedagogical requirements. Objectives: To evaluate the effectiveness and applicability of the modality principle, which was previously…

Purpose: A fundamental feature of human speech is variation, including the manner of phonation, as exemplified in the case of whispered speech. In this study, we employed whispered speech to examine an unresolved issue about congenital amusia, a neurodevelopmental disorder of musical pitch processing, which also affects speech pitch processing…

In this work we ask whether at birth, the human brain responds uniquely to speech, or if similar activation also occurs to a non-speech surrogate 'language'. We compare neural activation in newborn infants to the language heard "in utero" (English), to an unfamiliar language (Spanish), and to a whistled surrogate language (Silbo Gomero)…

This study investigated the cognitive and social processes through which high school students acquire the differential concepts through communication in a dynamic geometry environment through some cases. Additionally, we observed how a dynamic geometry environment affects these processes. To achieve this objective, eight students were recruited by…

There is an ongoing debate whether phonological deficits in dyslexics should be attributed to (a) less specified representations of speech sounds, like suggested by studies in young children with a familial risk for dyslexia, or (b) to an impaired access to these phonemic representations, as suggested by studies in adults with dyslexia. These…

Individuals with autism spectrum disorder (ASD) often exhibit disordered speech prosody, but sources of disordered prosody remain poorly understood. We explored patterns of temporal alignment and prosodic grouping in a speech-based metronome repetition task as well as manual coordination in a drum tapping task among Cantonese speakers with ASD and…

Purpose: The purpose of this study was to examine fatigue associated with sustained and effortful speech-processing in children with mild to moderately severe hearing loss. Method: We used auditory P300 responses, subjective reports, and behavioral indices (response time, lapses of attention) to measure fatigue resulting from sustained…

Background: Phonological difficulties in children with developmental language disorder (DLD) are well documented. However, abilities regarding prosody, the rhythmic and melodic characteristics of language, have been less widely studied, particularly in Spanish. Moreover, the scant research findings that have been reported are contradictory. These…

This study examines the discourse basis for referent accessibility and its relation to the choice of referring expressions by children with Autism Spectrum Disorder (ASD) and typically developing children. The aim is to delineate how the linguistic and extra-linguistic context affects referent accessibility to the speaker. The study also examines…

Background: Social communication problems are common in adults with traumatic brain injury (TBI), particularly problems in spoken discourse. Social communication problems are thought to reflect underlying cognitive impairments. Aims: To measure the contribution of two cognitive processes, executive functioning (EF) and theory of mind (ToM), to the…

Purpose: Studies suggest that deficits in auditory processing predict cognitive decline and dementia, but those studies included limited measures of auditory processing. The purpose of this study was to compare older adults with and without probable mild cognitive impairment (MCI) across two domains of auditory processing (auditory performance in…

Reading fluency is often predicted by rapid automatized naming (RAN) speed, which as the name implies, measures the automaticity with which familiar stimuli (e.g., letters) can be retrieved and named. Readers with dyslexia are considered to have less "automatized" access to lexical information, reflected in longer RAN times compared with…

Purpose: The purpose of this study was to report how "verbal rehearsal speed" (VRS), a form of covert speech used to maintain verbal information in working memory, and another verbal processing speed measure, perceptual encoding speed, are related to 3 domains of executive function (EF) at risk in cochlear implant (CI) users: verbal…

Purpose: In this study, the authors examined the ability of subjects with cochlear implants (CIs) to discriminate voice gender and how this ability evolved as a function of CI experience. Method: The authors presented a continuum of voice samples created by voice morphing, with 9 intermediate acoustic parameter steps between a typical male and a…
