background: according to previous studies, most of the speech recognition disorders in older adults are the results of deficits in audibility and auditory temporal resolution. in this paper, the effect of ageing on timecompressed speech and auditory temporal resolution by word recognition in continuous and interrupted noise was studied. methods: a time-compressed speech test (tcst) was conducte...

introduction: prior studies comparing hemodynamic response function (hrf) in the young and elderly adults based on fmri data have reported inconsistent findings for brain vision and motor regions in healthy aging. it is shown that the averaging method employed in all previous works has caused this inconsistency. the averaging is so sensitive to outliers and noise. however, fmri data are obscure...

KEY FINDINGS Data from the National Health Interview Survey: 2008-2009. More than one-half of Hispanic young adults aged 20-29 years were uninsured in 2008-2009 compared with one-third of non-Hispanic black young adults and almost one-quarter of non-Hispanic white young adults. Among young adults aged 20-29 years, non-Hispanic white (66%) young adults were twice as likely as Hispanic (33%) youn...

When presented with several time-compressed sentences, young adults' performance improves with practice. Such adaptation has not been studied in older adults. To study age-related changes in perceptual learning, the authors tested young and older adults' ability to adapt to degraded speech. First, the authors showed that older adults, when equated for starting accuracy with young adults, adapte...

purpose accurate measurement or prediction of fat mass is useful in physiology, nutrition and clinical medicine. most predictive equations currently used to assess percentage of body fat or fat mass, using simple anthropometric measurements were derived from people in western societies and they may not be appropriate for individuals with other genotypic and phenotypic characteristics. we develo...
