Description
The purpose of the present study was to determine if vocabulary knowledge is related to degree of hearing loss. A 50-question multiple-choice vocabulary test comprised of old and new words was administered to 43 adults with hearing loss (19 to 92 years old) and 51 adults with normal hearing (20 to 40 years old). Degree of hearing loss ranged from mild to moderately-severe as determined by bilateral pure-tone thresholds. Education levels ranged from some high school to graduate degrees. It was predicted that knowledge of new words would decrease with increasing hearing loss, whereas knowledge of old words would be unaffected. The Test of Contemporary Vocabulary (TCV) was developed for this study and contained words with old and new definitions. The vocabulary scores were subjected to repeated-measures ANOVA with definition type (old and new) as the within-subjects factor. Hearing level and education were between-subjects factors, while age was entered as a covariate. The results revealed no main effect of age or education level, while a significant main effect of hearing level was observed. Specifically, performance for new words decreased significantly as degree of hearing loss increased. A similar effect was not observed for old words. These results indicate that knowledge of new definitions is inversely related to degree of hearing loss.

Description
Hearing loss is a serious condition that affects many adults and includes both age-related loss and non-age related loss (genetics, illness, or trauma). The focus of this thesis is on age related hearing loss. Almost half of people over the age of 75 have some degree of hearing loss, along with nearly a third of those between 65 and 74, and an eighth of 45-64 year olds. About 36 million American adults have hearing loss, and 44% of those report that their relationships have suffered as a result of hearing loss. This is a serious issue, which is why I've spent my senior year of college to create a product that improves the life of someone with hearing loss, such as my 90-year-old grandfather. The result of my labors is Suono, a product for those with hearing aids to better hear their loved ones, close friends, and others they care about.

Description
Cochlear implants are electronic medical devices that create hearing capabilities in those with inner ear damage that results in total or partial hearing loss. The decision to get a cochlear implant can be difficult and controversial. Cochlear implants have many physical and social impacts on cochlear implant users. The aim of this study was to evaluate how patient narratives written by people with cochlear implants (or their caregivers) express issues of quality of life and personhood related to the use of this medical device. The methodology used to answer this question was a content analysis of patient narratives. The content analysis was done using grounded theory and the constant comparative method. Two sensitizing concepts, quality of life and personhood, were used and became the large umbrella themes found in the narratives. Under the major theme of quality of life, the sub-themes that emerged were improved hearing, improved communication skills, and assimilation into the hearing world. Under the major theme of personhood, the sub-themes that emerged were confidence, self-image, and technology and the body. Another major theme, importance of education, also emerged. In general, cochlear implant users and their caregivers expressed in their narratives that cochlear implants have positive effects on the quality of life of cochlear implant users. This is because almost all of the narrative writers reported improved hearing, improved communication skills, and better assimilation into the hearing world. In addition, it was found that cochlear implants do not have a significant affect on the actual personal identity of cochlear implant users, though they do make them more confident. The majority of cochlear implant users expressed that they view the cochlear implant device as an assistive tool they use as opposed to a part of themselves. Lastly, there is a need for more awareness of or access to education and therapy for cochlear implant users.

Description
The purpose of this study was to explore the effects of word type, phonotactic probability, word frequency, and neighborhood density on the vocabularies of children with mild-to-moderate hearing loss compared to children with normal hearing. This was done by assigning values for these parameters to each test item on the Peabody Picture Vocabulary Test (Version III, Form B) to quantify and characterize the performance of children with hearing loss relative to that of children with normal hearing. It was expected that PPVT IIIB scores would: 1) Decrease as the degree of hearing loss increased. 2) Increase as a function of age 3) Be more positively related to nouns than to verbs or attributes. 4) Be negatively related to phonotactic probability. 5) Be negatively related to word frequency 6) Be negatively related to neighborhood density. All but one of the expected outcomes was observed. PPVT IIIB performance decreased as hearing loss increased, and increased with age. Performance for nouns, verbs, and attributes increased with PPVT IIIB performance, whereas neighborhood density decreased. Phonotactic probability was expected to decrease as PPVT IIIB performance increased, but instead it increased due to the confounding effects of word length and the order of words on the test. Age and hearing level were rejected by the multiple regression analyses as contributors to PPVT IIIB performance for the children with hearing loss. Overall, the results indicate that there is a 2-year difference in vocabulary age between children with normal hearing and children with hearing loss, and that this may be due to factors external to the child (such as word frequency and phonotactic probability) rather than the child's age and hearing level. This suggests that children with hearing loss need continued clinical services (amplification) as well as additional support services in school throughout childhood.

Description
Veterans are approximately 30% more likely than non-veterans to suffer from severe hearing impairment. Tinnitus, or ringing in the ears, which is increasingly common among military service men and women, has been linked to significant cognitive and psychological impairment and can be worsened by the same sounds that trigger post-traumatic stress disorder (PTSD). In fact, tinnitus and PTSD often present as comorbidities, and recent studies suggest these two disorders may share a common neurological pathway. Additional studies are required to better understand the connection between hearing loss and impaired cognitive function such as that observed in with PTSD. Here, we use the fruit fly, Drosophila melanogaster, to explore the relationship between hearing loss and cognitive function. Negative geotaxis climbing assays and courtship behavior analysis were used to examine neurobehavioral changes induced by prolonged, intense auditory stimulation. Preliminary results suggest that exposure to loud noise for an extended period of time significantly affected Drosophila behavior, with males being more sensitive than females. Based on our results, there appears to be a potential connection between noise exposure and behavior, further suggesting that Drosophila could be an effective model to study the link between hearing loss and PTSD.
