![]() ![]() Older people with hearing loss have considerably more difficulty accurately perceiving rapid speech than either younger listeners with hearing loss or older listeners with normal hearing, because of the combined effects of hearing loss and decline in speed of signal processing ( Gordon-Salant and Fitzgibbons, 1993). Age-related deficits for processing rapid speech, described above, have been observed in older listeners with normal hearing ( Gordon-Salant and Fitzgibbons, 1993). This age-related decline in processing rapid signals has been attributed to a cognitive decline in speed of information processing ( Salthouse, 1996) as well as to a more central deficit in neural synchrony for coding of rapid signal onsets, as suggested by animal models of aging (e.g., Hellstrom and Schmiedt, 1990 Boettcher et al. 1993).Īccurate perception of the televised message also might be compromised in older adults because of a decline in the ability to process auditory signals presented at a rapid rate ( Gordon-Salant and Fitzgibbons, 1993 Fitzgibbons, et al. 2007), older people appear to derive significant benefit from the integration of auditory and visual cues ( Walden et al. Although recent reports suggest that older individuals do not lipread visual-only signals as well as younger adults ( Tye-Murray et al. ![]() This limitation may be mitigated somewhat by the availability of speechreading cues, which are highly beneficial for speech understanding when combined with auditory information ( Grant et al., 1998). Age-related hearing loss not only attenuates sound, but also affects the clarity with which a spoken message is received. One potential factor is hearing loss, which affects at least one-third of adults over 65 years and one-half of those over 80 years ( Moscicki et al., 1985 Cruikshanks et al. There are many factors, however, that may limit television viewing by older people. They rely on television for national and world news and for entertainment ( Goodman, 1990). Adults over 65 years watch more television than younger age groups, with an average of 3.5–5.25 hours of television per day ( Hanley, 2002 Mares & Woodard, 2006). Approximately 92% of people between 65 and 74 years, and 95% of people 75 years and older watch television every day ( Hanley, 2002). ![]()
