Purpose An increasing number of individuals with residual or even normal contralateral hearing are being considered for cochlear implantation. It remains unknown whether the presence of contralateral hearing is beneficial or detrimental to their perceptual learning of cochlear implant (CI)–processed speech. The aim of this experiment was to provide a first insight into this question using acoustic simulations of CI processing. Method Sixty normal-hearing listeners took part in an auditory perceptual learning experiment. Each subject was randomly assigned to one of three groups of 20 referred to as NORMAL, LOWPASS, and NOTHING. The experiment consisted of two test phases separated by a training phase. In the test phases, all subjects were tested on recognition of monosyllabic words passed through a six-channel “PSHC” vocoder presented to a single ear. In the training phase, which consisted of listening to a 25-min audio book, all subjects were also presented with the same vocoded speech in one ear but the signal they received in their other ear differed across groups. The NORMAL group was presented with the unprocessed speech signal, the LOWPASS group with a low-pass filtered version of the speech signal, and the NOTHING group with no sound at all. Results The improvement in speech scores following training was significantly smaller for the NORMAL than for the LOWPASS and NOTHING groups. Conclusions This study suggests that the presentation of normal speech in the contralateral ear reduces or slows down perceptual learning of vocoded speech but that an unintelligible low-pass filtered contralateral signal does not have this effect. Potential implications for the rehabilitation of CI patients with partial or full contralateral hearing are discussed.

Abstract Learning to listen and speak are well-established preludes for reading, writing, and succeeding in mainstream educational settings. Intangibles beyond the ubiquitous test scores that typically serve as markers for progress in children with hearing loss are embedded in descriptions of the educational and social development of four young women. All were diagnosed with severe-to-profound or profound hearing loss as toddlers, and all were fitted with hearing aids and given listening and spoken language therapy. Compiling stories across the life span provides insights into what we can be doing in the lives of young children with hearing loss.

To ensure optimal auditory development for the acquisition of spoken language, children with hearing loss require early diagnosis, effective ongoing audiological management, well fit and maintained hearing technology, and appropriate family-centered early intervention. When these elements are in place, children with hearing loss can achieve developmental and communicative outcomes that are comparable to their hearing peers. However, for these outcomes to occur, clinicians—early interventionists, speech-language pathologists, and pediatric audiologists—must participate in a dynamic process that requires careful monitoring of countless variables that could impact the child's skill acquisition. This paper addresses some of these variables or “red flags,” which often are indicators of both minor and major issues that clinicians may encounter when delivering services to young children with hearing loss and their families.

Abstract As increasing numbers of speech language pathologists (SLPs) have embraced their burgeoning roles in written as well as spoken language intervention, they have recognized that there is much to be gained from the research in reading. While some SLPs reportedly fear they will “morph” into reading teachers, many more are confidently aware that SLPs who work with adult clients routinely use reading as one of their rehabilitation modalities. Reading functions as both a tool to reach language in adults, and as a measure of successful therapy. This advanced cognitive skill can serve the same purpose for children. Language is the foundational support to reading. Consequently spoken language problems are often predictors of reading and writing challenges that may be ahead for the student (Juel & Deffes, 2004; Moats, 2001; Wallach, 2004). A targeted review of reading research may assist the SLP to appreciate the language/reading interface.
