“…Spectral abilities, as measured by spectral-ripple discrimination thresholds were statistically identical to those of adult CI users, but the child subjects were generally poor at the Schroeder-phase discrimination test and their scores were significantly worse than those of the adults. Previous studies demonstrated that temporal sensitivity takes longer to develop than frequency sensitivity, and normal-hearing children do not develop adult temporal processing ability until the age of 11 years [Wightman et al, 1989;Elfenbein et al, 1993;Buss et al, 1999]. In young normal-hearing listeners, peripheral temporal mechanisms may be adult-like, but the central auditory system may be less efficient in extracting temporal information [Plack and Moore, 1990].…”

recognition score was 68.6%, and the mean SRT in steady noise was -8.5 dB SNR. The children's spectral-ripple resolution, CNC word recognition, and SRT in noise performances were, within statistical bounds, the same as in a population of postlingually deafened adult CI users. However, Schroeder-phase discrimination and music perception were generally poorer than in the adults. It is possible then that this poorer performance seen in the children might be partly accounted for by the delayed maturation in their temporal processing ability, and because of this, the children's performance may have been driven more by their spectral sensitivity.

“…However, it is very difficult to assess whether children's ability to perceive consonant clusters is equivalent to that of adults. Although children's auditory perceptual systems are reported to undergo developmental changes ( Elfenbein, Small, & Davis, 1993), no studies to date have shown that children's cluster-perceiving mechanisms are deficient.…”

Purpose: This study provides a comprehensive examination of substitutions that occur at Greenlee's 3rd stage of cluster development (M. Greenlee, 1974). At this stage of cluster acquisition, children are able to produce the correct number of consonants but with 1 or more of these consonants being substituted for another. Method: Participants were 11 typically developing children ages 1;5-2;7 (years;months) who were from monolingual English-speaking homes. Consonant clusters in both word-initial and word-final position were elicited using a picture identification task. Results: Although previous studies have suggested that most cluster substitutions can be predicted from the errors children make on the corresponding singletons, our findings indicate that almost one third of substitutions in clusters are not predictable in this way. Furthermore, the majority of unpredictable substitutions produced by the children in this study resulted in clusters in which both consonants in the cluster shared the same place and/or manner of articulation. Thus, almost 70% of unpredictable substitutions appear to be motivated by assimilation within the cluster. Conclusion: Ease of articulation provides the most convincing explanation for within-cluster assimilation.

“…Therefore, it is not clear whether attention indeed drives the development of frequency discrimination or whether both attention and discrimination simply improve with age. As for the development of duration discrimination, to our knowledge this has been investigated in two published studies only (Elfenbein et al, 1993;Jensen & Neff, 1993), both showing development during the primary-school years.…”

“…Specifically, we are interested in the development of auditory frequency and duration discrimination, as previous reports indicate that adult-like discrimination performance is not attained prior to 10 years of age (Elfenbein, Small, & Davis, 1993;Moore, Cowan, Riley, Edmondson-Jones, & Ferguson, 2011) and that non-sensory factors are probably involved in this prolonged development Wightman & Allen, 1992).…”
