The present study explores phonetic processing in deaf children with cochlear implants (CIs) when they have to learn phonetically similar words. Forty-six 34-to-78-month-old French-speaking deaf children with CIs were tested on 16 different trials. In each trial, they were first trained with two word-object pairings, and then a third object was…

In Brazil there are no specific tests for either signed or spoken language for deaf children. A protocol evaluating communicative abilities independent of modality of communication (sign language or spoken language), and comprising assessments of (a) pragmatic profile; (b) modality of communication and linguistic level; (c) complexity of…

Children with autism spectrum disorder (ASD) who have native exposure to a sign language such as American Sign Language (ASL) have received almost no scientific attention. This paper reports the first studies on a sample of five native-signing children (four deaf children of deaf parents and one hearing child of deaf parents; ages 4;6 to 7;5)…

Background: There is minimal research on the contribution of visual information on speech intelligibility for individuals with a laryngectomy (IWL). Aims: The purpose of this project was to determine the effects of mode of presentation (audio-only, audio-visual) on alaryngeal speech intelligibility. Method: Twenty-three naive listeners were…

We first review the mirror-system hypothesis on the evolution of the language-ready brain, stressing the important role of imitation and protosign in providing the scaffolding for protospeech. We then assess the role of social interaction and non-specific knowledge of language in the emergence of new sign languages in deaf communities (focusing on…

A basic tenet of developmental neurobiology is that certain areas of the cortex will re-organize, if appropriate stimulation is withheld for long periods. Stimulation must be delivered to a sensory system within a narrow window of time (a sensitive period) if that system is to develop normally. In this article, we will describe age cut-offs for a…

Learning to read is a major obstacle for children who are deaf. The otherwise significant role of phonology is often limited as a result of hearing loss. However, semantic knowledge may facilitate reading comprehension. One important aspect of semantic knowledge concerns semantic categorization. In the present study, the quality of the semantic…

The mirror neuron system (MNS) is a trimodal system composed of neuronal populations that respond to motor, visual, and auditory stimulation, such as when an action is performed, observed, heard or read about. In humans, the MNS has been identified using neuroimaging techniques (such as fMRI and mu suppression in the EEG). It reflects an…

In normal-hearing children the latency of the P1 component of the cortical evoked response to sound varies as a function of age and, thus, can be used as a biomarker for maturation of central auditory pathways. We assessed P1 latency in 245 congenitally deaf children fit with cochlear implants following various periods of auditory deprivation. If…

Ways in which parents cope with the diagnosis of deafness are considered in a chronological discussion from pregnancy to diagnosis, education, and habilitation. The importance of parent counseling and of the total communication effort is stressed. (CL)

This study investigated the preservation of second formant transition acoustic cues to intelligibility in speech produced during simultaneous communication (SC) from a locus equation perspective with 12 normal hearing, experienced sign language users. Results were consistent with previous research indicating that temporal alterations produced by…

The study investigated 14 school-age deaf children's responses to a listener's indication of communication breakdown and examined whether responses were related to syntactic or semantic abilities and/or typical mode of communication. Most revisions involved changes in sentence constituents. The frequency of revisions, repetitions, and no responses…

Investigations in recent years have indicated that only about 20% of the speech output of the deaf is understood by the "person on the street." This lack of intelligibility has been associated with some frequently occurring segmental and suprasegmental errors.

We examined the influence of sign language iconicity on children's ability to describe the function of objects. Forty-eight hearing preschoolers were divided into three groups and asked to describe the function of 15 high and 15 low iconic signs. We questioned the Hearing/Verbal (H/V) group verbally, Hearing/Verbal+Sign (H/V+S) group verbally with…

Two studies examined the ability of 22 deaf high school students to instantiate (select appropriate word meaning from context) particular exemplars of general nouns and to use those instantiations as retrieval cues. Among results were that subjects could instantiate when asked to do so but did not do so spontaneously. (Author/DB)
