“…For example, Zeigler et al (2005) report that whilst children with language impairment perform as well as a younger language-matched control group on a speech discrimination task in optimal listening conditions, they performed significantly less well in background noise. Similar findings are reported for children with difficulties with literacy and attention deficit hyperactivity disorder (Bradlow et al, 2003;Geffner et al, 1996). The speech discrimination difficulties of children with a history of otitis media with effusion may also only be observable in background noise conditions (Schilder et al, 1994).…”

Few materials are available to assess speech perceptual skills in young children without hearing impairments. However, children with a range of developmental conditions are at risk of speech discrimination deficits. Tasks that reliably assess speech perception skills are thus necessary for research and clinical practice. The development and application of two speech perception tests are described. Data were collected from 105 children, aged 4-5 years, attending mainstream schools, on two tasks, mispronunciation detection and non-word XAB, in quiet and in a background of multi-talker babble. Children's receptive language skills were also measured. Performance on mispronunciation detection was significantly better than on the XAB non-word task, and significantly better in quiet than in babble. Performance significantly improved with age, and speech discrimination was significantly related to receptive language abilities. Scores obtained in quiet and in babble were highly correlated and findings suggest there may be no advantage to testing in noise, except to avoid ceiling effects on performance. These tasks prove useful in the assessment of young children who may have speech discrimination deficits.

“…Similarly, behavioral research supports the notion that phonologic processing skills are fundamental to language development and to subsequent reading abilities (Brady 1991; Catts et al 1999; Wagner et al 1994). Others demonstrated a connection between auditory processing and attention deficits (Geffner et al 1996) or learning disabilities (Kraus et al 1996). Together, these findings highlight the importance of proper auditory processing and speech discrimination for overall cognitive development and functioning.…”

BackgroundTobacco smoking during pregnancy is known to adversely affect development of the central nervous system in babies of smoking mothers by restricting utero–placental blood flow and the amount of oxygen available to the fetus. Behavioral data associate maternal smoking with lower verbal scores and poorer performance on specific language/auditory tests.ObjectivesIn the current study we examined the effects of maternal smoking during pregnancy on newborns’ speech processing ability as measured by event-related potentials (ERPs).MethodHigh-density ERPs were recorded within 48 hr of birth in healthy newborn infants of smoking (n = 8) and nonsmoking (n = 8) mothers. Participating infants were matched on sex, gestational age, birth weight, Apgar scores, mother’s education, and family income. Smoking during pregnancy was determined by parental self-report and medical records. ERPs were recorded in response to six consonant–vowel syllables presented in random order with equal probability.ResultsBrainwaves of babies of nonsmoking mothers were characterized by typical hemisphere asymmetries, with larger amplitudes over the left hemisphere, especially over temporal regions. Further, infants of nonsmokers discriminated among a greater number of syllables whereas the newborns of smokers began the discrimination process at least 150 msec later and differentiated among fewer stimuli.ConclusionsOur findings indicate that prenatal exposure to tobacco smoke in otherwise healthy babies is linked with significant changes in brain physiology associated with basic perceptual skills that could place the infant at risk for later developmental problems.

“…A four-alternative, picture-pointing task was used because of its documented success with young children ͑Goldman et al., 1976;Geffner et al, 1996͒ and its obvious advantages over word-generation tasks ͑Elliott et al, 1979͒. Target words were presented in a low-context carrier phrase ͑''Touch the X''͒ because of the present focus on perceptual, or bottomup, factors and the reported advantage of sentential contexts over words presented in isolation ͑Craig, 1988͒.…”

Children 5, 9, and 11 years of age and young adults attempted to identify the final word of sentences recorded by a female speaker. The sentences were presented in two levels of multitalker babble, and participants responded by selecting one of four pictures. In a low-noise condition, the signal-to-noise ratio (SNR) was adjusted for each age group to yield 85% correct performance. In a high-noise condition, the SNR was set 7 dB lower than the low-noise condition. Although children required more favorable SNRs than adults to achieve comparable performance in low noise, an equivalent decrease in SNR had comparable consequences for all age groups. Thus age-related differences on this task can be attributed primarily to sensory factors.
