English Prosodic Focus Marking by Cantonese Trilingual Children With and Without Autism Spectrum Disorder.

Purpose: The current study investigated English prosodic focus marking by autistic and typically developing (TD) Cantonese trilingual children, and examined the potential differences in this regard compared to native English-speaking children.

Method: Forty-eight participants were recruited with 16 speakers for each of the three groups (Cantonese-speaking autistic [CASD], Cantonese-speaking TD [CTD], and English-speaking TD [ETD] children), and prompt questions were designed to elicit desired focus type (i.e.

Corpus of Mandarin Child Language: a preliminary study on the acquisition of semantic content categories in Mandarin-speaking preschoolers.

In studying language acquisition in children, sizable research studies have been focusing on the investigation of form and lexical semantics. This study aims to establish a child language database annotated both syntactically with part of speech and semantically with semantic content category to supplement the study of child language acquisition in the semantic domain beyond lexical level. The Corpus of Mandarin Child Language (CMCL) that documented the production of different semantic content categories by Mandarin-speaking children was established.

Phonetic entrainment in L2 human-robot interaction: an investigation of children with and without autism spectrum disorder.

Phonetic entrainment is a phenomenon in which people adjust their phonetic features to approach those of their conversation partner. Individuals with Autism Spectrum Disorder (ASD) have been reported to show some deficits in entrainment during their interactions with human interlocutors, though deficits in terms of significant differences from typically developing (TD) controls were not always registered. One reason related to the inconsistencies of whether deficits are detected or not in autistic individuals is that the conversation partner's speech could hardly be controlled, and both the participants and the partners might be adjusting their phonetic features.

Systematic language input improved productions of elaborated verb phrases of Cantonese-speaking children with language difficulties.

It has been well-documented that language input designed according to the principles of statistical learning can promote language acquisition among children with or without language disorder. Cantonese-speaking children with language disorder were reported to have difficulties using expanded verb phrases and prepositional phrases, but the corresponding intervention is relatively unexplored. The current study evaluated the efficacy of an intervention designed using the statistical learning principles to promote the acquisition of these two structures.

Comprehension of presupposition triggers in Cantonese-speaking children with and without autism spectrum disorders.

Built on a previous finding that children with autism spectrum disorders (ASD) had difficulty comprehending presuppositions, a domain of knowledge which is crucial for successful communication, the present study investigated the comprehension of seven types of presupposition trigger - namely definite descriptions, factive predicates, change-of-state verbs, implicative verbs, iteratives, temporal clauses, and counterfactual conditionals - in Cantonese-speaking children with and without ASD. Twenty-seven children with ASD (mean age 9.07) were compared with 23 typically developing (TD) children matched on chronological age and 21 TD children matched on language ability (LA).

Comprehension of literal statements and similes in Cantonese-speaking children with and without autism spectrum disorders.

While it has been proposed, following relevance theory, that similes can be understood at a purely literal level on a par with literal statements, it remains unclear whether children with high-functioning autism spectrum disorders (HFASD) perform similarly to typically developing (TD) children in comprehending literal statements and similes. The present study investigated comprehension of literal statements and similes in Cantonese-speaking children with HFASD and TD children matched on both chronological age and verbal mental age. An utterance-picture matching task was devised to assess their comprehension of literal statements and similes in Cantonese.

Comprehension of presuppositions in school-age Cantonese-speaking children with and without autism spectrum disorders.

While an enormous amount of research has been done on the deficient conversation skills in individuals with autism spectrum disorders (ASD), little is known about their performance on presuppositions, a domain of knowledge that is crucial for successful communication. This study investigated the comprehension of four types of presupposition, namely existential, factive, lexical and structural presuppositions, in school-age Cantonese-speaking children with and without ASD. A group of children with ASD (n = 21), mean age 8.

Auditory neuropathy/auditory dys-synchrony in school children with hearing loss: frequency of occurrence.

Objective: The frequency of occurrence of a recently identified hearing disorder, auditory neuropathy/auditory dys-synchrony (AN/AD), was investigated in children with hearing impairment in Hong Kong.

Methods: In this study, 56 students, aged 7-18 years, attending primary divisions in schools for the hearing impaired were screened using otoacoustic emission procedures.

Results: One student in the study group was found to have intact outer hair cell function.

Tone discrimination in Cantonese-speaking children using a cochlear implant.

Most tone perception tests for Cantonese-speaking cochlear implant users have been based on tone identification tasks which require significant cognitive development to be successfully completed. Results from such tests suggest that cochlear implant child users are performing at about chance level and may not be receiving much information about pitch using the implant. This paper reports on the ability of cochlear implant child users to discriminate pitch variations in Cantonese by using an experimental procedure based on play audiometry.
