Hearing, Speech, and Language Sciences

The department conducts extensive research on communication access technology and rehabilitation for Deaf and hard of hearing people through its Rehabilitation Engineering Research Center on Hearing Enhancement. Faculty, staff, and students conduct research on hearing, speech, spoken and visual language, and balance assessment and intervention across the human lifespan.


Spatial Navigation Abilities in Deaf Older Adults: With and Without Vestibular Impairment

ID: 3434
Status: Ongoing
Start date: October 2016
End Date: October 2019

Description

The purposes of this 3-year project are to: 1. develop and adapt spatial memory and spatial navigation assessment tools to be administered to the deaf/Deaf population; 2. characterize the spatial memory and spatial navigation abilities in young adults who are deaf, with and without vestibular impairments (VI); and 3. assess the role of ASL in spatial memory and navigation abilities in older adults. Older individuals with VI may present with difficulty in spatial memory and navigation, which increases the risk of falling or wayfinding difficulties. High prevalence (54-85%) of VI in the deaf population puts older deaf individuals at risk, while evidence of high visuo-spatial IQ in ASL users suggests that the spatial cognitive functions among deaf ASL users with VI may not be as affected as those among deaf non-ASL users with VI. To address purposes #1 and #2, spatial memory and spatial navigation assessment tools (virtual reality navigation and memory tasks, sense-of-direction questionnaire) will be normed and adapted to the young deaf adult population (ages 21-35). To address purpose #3, these spatial memory and navigation tasks are administered to subjects 60 years or older with different experiences in hearing status, ASL use, and VI.

Spatial Navigation Abilities in Deaf Population

ID: 3395
Status: Ongoing
Start date: October 2016

Description

The purposes of the study are to: 1. develop and adapt spatial memory and spatial navigation assessment tools to be administered to deaf/Deaf population; 2. characterize the spatial memory and spatial navigation abilities in older adults who were either born deaf or became deaf before Kindergarten, with and without vestibular impairments (VI); and 3. assess the role of ASL in spatial memory and navigation abilities.Older individuals with VI may present with difficulty with spatial memory and navigation, which increases the risk of falling or wayfinding difficulties. High prevalence (54-85%) of VI in deaf population puts older deaf individuals at risk, while evidence of high visuo-spatial IQ in ASL users suggests that the spatial cognitive functions among deaf ASL users with VI may not be as affected as those among deaf non-ASL users with VI. To address purpose #1, spatial memory and spatial navigation assessment tools (virtual reality navigation and memory tasks, real-life wayfinding tasks, daily skills, questionnaires) will be normed and adapted to the young adult deaf population (ages 21-35). To address purposes #2 and 3, these spatial memory and navigation tasks are administered to subjects 65 years or older, grouped based on hearing status, ASL use, and VI.
