This paper addresses effects of age and sex on certain acoustic properties of speech, given conflicting findings on such effects reported in prior research. The speech of 27 younger adults (15 women, 12 men; mean age 25.5 years) and 59 older adults (32 women, 27 men; mean age 75.2 years) was evaluated for identification of differences for sex and…

It is well documented that aging adversely affects the ability to perceive time-varying acoustic cues. Here we review how physiological measures are being used to explore the effects of aging (and concomitant hearing loss) on the neural representation of temporal cues. Also addressed are the implications of current research findings on the…

The human peripheral auditory system is fully developed at birth; however, myelination continues for several years in the higher auditory pathways. The aim of the present study was to assess the maturation course of the frequency and duration pattern tests and the middle latency response (MLR). One hundred and fifty normal participants ranging…

A study that compared the receptive and expressive prosodic abilities of 30 Dutch children (ages 4-6) with language impairments to the abilities of typical children, found they performed less accurately on a prosodic imitation task but did not differ on an emotion identification task. Children performed better with increasing age. (Author/CR)
