Previous research has hypothesized that human sequential processing may be dependent upon hearing experience (the "auditory scaffolding hypothesis"), predicting that sequential rule learning abilities should be hindered by congenital deafness. To test this hypothesis, we compared deaf signer and hearing individuals' ability to acquire…

The process of spoken word recognition is influenced by both bottom-up sensory information and top-down cognitive information. These cues are used to process the phonological and semantic representations of speech. Several studies have used EEG/ERPs to study the neural mechanisms of children's spoken word recognition, but less is known about the…

Perceptual restoration occurs when the brain restores missing segments from speech under certain conditions. It is investigated in the auditory modality, but minimal evidence has been collected during speechreading tasks. The authors measured perceptual restoration in speechreading by individuals with hearing loss and compared it to perceptual…

The auditory scaffolding hypothesis states that early experience with sound underpins the development of domain-general sequence processing abilities, supported by studies observing impaired sequence processing in deaf or hard-of-hearing (DHH) children. To test this hypothesis, we administered a sequence processing task to 77 DHH children who use…

Purpose: The primary purpose of this study was to explore the audiovisual speech perception strategies.80.23.47 adopted by normal-hearing and deaf people in processing familiar and unfamiliar languages. Our primary hypothesis was that they would adopt different perception strategies due to different sensory experiences at an early age, limitations…

It is imperative that teachers have the knowledge and resources to support children who are deaf and use a cochlear implant in general education classrooms. The recommendations presented in this article provide teachers with the information necessary to promote a child's academic progress, communication needs, and social development. In order to…

The researchers evaluated the contribution of cochlear implants (CIs) to speech perception by a sample of prelingually deaf individuals implanted after age 8 years. This group was compared with a group with profound hearing impairment (HA-P), and with a group with severe hearing impairment (HA-S), both of which used hearing aids. Words and…

The perceptual loop theory of self-monitoring posits that auditory speech output is parsed by the comprehension system. For sign language, however, visual input from one's own signing is distinct from visual input received from another's signing. Two experiments investigated the role of visual feedback in the production of American Sign Language…

Experiment I showed that hearing subjects outperformed deaf subjects on a lipreading task, possibly because they could supplement lip-read stimuli with stored auditory information. Experiment II demonstrated that sighted subjects did not use stored visual information to supplement auditory input, for they performed no differently from congenitally…

Results failed to prove that a deaf group would perform as well as a hearing group on a test of associated pairs with high visual imagery but worse with material with high auditory imagery. (KS)

Videotaped productions of isolated American Sign Language signs or sentences were presented at speeds of two to six times normal. Results indicated a breakdown in intelligibility at around 2.5 to 3 times the normal rate. Results are similar to those found for auditory reception of time-compressed speech suggesting a modality-independent limit to…

Two deaf children of deaf parents were studied over a period of several years for their acquisition of "-ing", "-'s"; "-s", "-d", and the particle "to." Although the children soon perceived the signed forms of these morphemes, they were slow to understand the function of the morphemes. (Author/LMO)

Provides an overview of how early identification and intervention for hearing impairment may benefit deaf infants' acquisition of symbolic language. Concludes that the role of the caregiver is central to the planning and success of early intervention programs for infants with deafness. (MDM)

This paper, discussing use of electrical stimulation by postlingually deafened adults to supplement speechreading, focuses on: information conveyed by vision, acoustic information needed to resolve visual confusions, basic psychophysical abilities of cochlear implant patients, auditory-alone and audiovisual perception by cochlear-implant patients,…

This study investigated associations between infants' prelinguistic communicative behaviors at 9 months and their communication and language performance at 12 and 18 months. The inclusion of both hearing (N=19) and deaf (N=16) infants in the study allowed identification of effects related to the receptive communication modality (vision versus…
