BACKGROUND Deafness is a complex and multifaceted phenomenon. The different ways of perceiving and understanding deafness have practical implications for research with deaf people. Whilst the deaf community is not homogenous, it is generally distinct from the hearing population. Consequently, the appropriateness of applying research methods and informed concern processes designed for the hearin...

The current study sought to identify and analyze how Black deaf and hard-of-hearing people conceptualize their deaf and hard-of-hearing identities. That is, what cultural and linguistic factors are involved and how do they interact? An existing measure of Deaf cultural identity, the Deaf Acculturation Scale (DAS), was used to evaluate these questions. Review of the measure's normative sample (n...

The absence of the ability to hear sounds in deaf people is an obstacle to optimal communication in a predominantly hearing world. Emergency situations harbor sufficient challenge for the hearing person and pose even greater barriers for the deaf and hard of hearing. During disasters and emergency situations, deaf people have great difficulty in obtaining and sharing information, increasing the...

This study investigated peripheral vision (at least 30° eccentric to fixation) development in profoundly deaf children without cochlear implantation, and compared this to age-matched hearing controls as well as to deaf and hearing adult data. Deaf and hearing children between the ages of 5 and 15 years were assessed using a new, specifically paediatric designed method of static perimetry. The d...

Altered regulation of the serotonin-1A (5-HT1A) receptor gene is implicated in major depression and mood disorders. The functional human 5-HT1A C(-1019)G promoter polymorphism (rs6295), which prevents the binding of Deaf-1/NUDR leading to dysregulation of the receptor, has been associated with major depression. In cell models Deaf-1 displays dual activity, repressing 5-HT1A autoreceptor express...

Previous research suggested an unexplained difference in the patterns of offending behaviors among deaf people when compared to hearing people. This study, conducted in Texas, compares the incidence and types of violent offenses of a deaf prison population in comparison to the hearing prison population. Sixty-four percent of deaf prisoners were incarcerated for violent offenses in comparison to...

This study investigated deaf adolescents' implicit and explicit awareness of subject-verb number agreement. In Experiment 1, a self-paced reading task, the reading times of deaf and hearing children (matched for reading and chronological age, mean=8;3 and 13;10 years) increased when sentences contained disagreeing subject-verb number markers. However, deaf adolescents' slowing occurred later in...

BACKGROUND Vocabulary knowledge and speechreading are important for deaf children's reading development but it is unknown whether they are independent predictors of reading ability. AIMS This study investigated the relationships between reading, speechreading and vocabulary in a large cohort of deaf and hearing children aged 5 to 14 years. METHODS AND PROCEDURES 86 severely and profoundly d...

Researchers and educators of the deaf often suggest that deaf children have a particular problem in understanding metaphorical uses of natural language. This paper reports two experiments whose results are incompatible with this view. Profoundly deaf children were presented with several short stories and were instructed to select (from a set of 4 alternatives) the sentence they thought best com...

A short-term longitudinal study was conducted to investigate possible benefits of cochlear implant (CI) use on the development of phonological awareness in deaf children. Nineteen CI users were tested on 2 occasions. Two groups of deaf children using hearing aids were tested once: 11 profoundly deaf and 10 severely deaf children. A battery of tests was designed to investigate syllable, rhyme, a...
