“…Importantly, it is possible that different listeners will use differing strategies. Such variation may depend on hearing ability, cognitive status, and susceptibility to the McGurk effect; all of which are known to influence multisensory integration abilities (e.g., Altieri & Hudock, 2014;Erber, 2003;Sommers, Tye-Murray, & Spehar, 2005).First, capacity is assessed by comparing the empirical RT distributions from trials in which both auditory and visual information are presented to the RT distributions obtained from trials in which auditory and visual-only information is present. This is done using integrated hazard functions, as follows.…”

This paper proposes a novel approach to assess audiovisual integration for both congruent and incongruent speech stimuli using reaction times (RT). The experiments are based on the McGurk effect, in which a listener is presented with incongruent audiovisual speech signals. A typical example involves the auditory consonant/b/combined with a visually articulated/g/, often yielding a perception of/d/. We quantify the amount of integration relative to the predictions of a parallel independent model as a function of attention and congruency between auditory and visual signals. We assessed RT distributions for congruent and incongruent auditory and visual signals in a within-subjects signal detection paradigm under conditions of divided versus focused attention. Results showed that listeners often received only minimal benefit from congruent auditory visual stimuli, even when such information could have improved performance. Incongruent stimuli adversely affected performance in divided and focused attention conditions. Our findings support a parallel model of auditory-visual integration with interactions between auditory and visual channels.Keywords Speech perception . Attention: Selective . Reaction time methodsWhat cognitive mechanisms underlie speech recognition when audition is supplemented with visual information? The modern era of research into how auditory and visual speech cues interact began with Sumby and Pollack's (1954) seminal experimental work on audiovisual (AV) enhancement: They showed that visual cues provided by a talker's lip-movements facilitate auditory recognition across a range of signal-to-noise ratios. However, Massaro (1987a) proved that this outcome did not necessarily demonstrate integration since a singlechannel model could theoretically predict the results.In a critical study two decades later, McGurk and Macdonald (1976) reported a dramatic perceptual integration phenomenon that resulted from the presentation of incongruent auditory-visual speech signals. In what became known as the "McGurk effect," presentation of the auditory consonant/ b/over a visually articulated/g/yielded a fused percept of/d/. Audiovisual fusions such as these occur when the perceptual system maps cues from conflicting signals onto a phonemic category distinct from either input signal.1 Thus, the McGurk effect is a prime candidate with which to probe the mechanisms underlying integration.Several studies of the McGurk effect have been carried out, with the majority using mean accuracy as the dependent variable. In these studies, performance in auditory and visualonly trials is compared to accuracy in audiovisual trials, usually via confusion matrices (e.g., Massaro, 1987aMassaro, , 1998Massaro, , 2004. These experimental designs and modeling efforts have shed considerable light on speech integration: Auditory and visual cues appear to interact in a multiplicative manner 1 This cannot be demonstrated conclusively without also measuring responses to the single modality presentations (cf. Massaro 1987a(cf. M...

“…While there are no currently available studies that directly examine the effects of visual acuity and/or cognitive function on hearing aid management skills, it is generally accepted that impaired cognitive function, particularly that associated with aging, influences the ability of the hearing aid user to appropriately adjust onboard controls (Kricos, 2006) and to understand and/or remember instructions for using and caring for a hearing aid (Erber, 2003). Similarly, many hearing aid users with poor functional vision reportedly experience difficulties in managing their devices (Erber, 2003).…”

“…These activities include, but are not limited to, inserting the earmold or hearing aid shell into the ear canal, locating and operating the onboard control(s), removing the device from the ear, changing the battery, and cleaning accumulations of debris from the sound bore (Dillon, 2001;Ward, Gowers, & Morgan, 1979). To perform these activities, the successful hearing aid user requires a sufficient degree of tactile sensitivity, manual dexterity, cognitive function, and visual acuity (Erber, 2003).…”

Trends in Amplification

A self-fitting hearing aid, designed to be assembled and programmed without audiological or computer support, could bring amplification to millions of people in developing countries, who remain unaided due to the lack of a local, professional, audiological infrastructure. The ability to assemble and insert a hearing aid is fundamental to the successful use of a self-fitting device. In this study, the management of such tasks was investigated. Eighty older, urban-dwelling, hearing-impaired adults in a developed country were asked to follow a set of written, illustrated instructions to assemble two slim-fit behindthe-ear hearing aids. Participants were allowed to access assistance with the task from an accompanying partner. A range of personal and audiometric variables was measured through the use of structured questionnaires and standardized tests of health literacy, cognitive function, and manual dexterity. The results showed that 99% of participants were able to complete the hearing aid assembly task, either on their own or with assistance. Health literacy, or the ability to read and understand health-related text, and gender most strongly influenced participants' ability to complete the assembly task independently and accurately. Higher levels of health literacy were associated with an increased likelihood of independent and successful task completion. Male participants were more likely to complete the task on their own, while female participants were more likely to assemble the device without errors. The results of this study will inform future work regarding development of educational material for the self-fitting hearing aid as well as candidacy for such a device.

Mrs N is a 75-year-old Latina woman evaluated for a 2-to 3-year history of hearing loss, more bothersome to family members than to herself. Mrs N lives with her husband of 49 years in their own home. She previously worked as a private tutor of Spanish and English at a language school. She is independent in activities of daily living. Although she denies having significant hearing problems, when pressed, Mrs N acknowledges having to increase the television volume, often choosing subtitles for greater comprehension, and having some difficulty with telephone conversations. It is difficult for her to understand speech in group settings. Her husband and daughters have noticed that she sometimes completely misunderstands what they are saying and must ask for clarification.Medical history is significant for varicose veins, hypercholesterolemia and hypertension both controlled by diet, and recent herpes zoster. She is taking no medications. On review of systems, she states that she does not have headaches, visual disturbances, or balance problems. She wears eyeglasses.On physical examination, the pinnae, canals, and tympanic membranes appear normal. Two years ago, audiometry documented bilateral symmetric moderate to severe sensorineural hearing loss, more pronounced in the higher frequencies, meeting criteria for bilateral hearing aid augmentation. Although her audiologist recommended a hearing aid evaluation at the time of examination, Mrs N and her sister did not think she needed it, so she did not undergo the evaluation. One year later, the audiologist again recommended a hearing aid consultation, but it was only after Mrs N's daughters pressured her repeatedly that she agreed to proceed with a hearing aid fitting.Mrs N and her daughter were interviewed by a Care of the Aging Patient editor between January 5 and 11, 2011. Perspectives Mrs N: To be truthful, I didn't notice anything [at first about hearing difficulties]. My daughters started telling me that I See also pp 1147 and Patient Page.
