Verbal Cognition

The aim of this study is to assess the role of bilateral/bimodal device use in auditory speech perception in complex listening situations and long-term verbal cognition in deaf children using cochlear implants (CIs). Two groups of children are compared (unilateral and bilateral device users) concerning vocabulary, speech perception at conversational level and in complex listening situations, and verbal cognition. In this retrospective study, we collected data of 37 deaf children with normal learning potential of whom 16 were unilateral CI users and 21 were bilateral device users (9 with a bimodal fitting and 12 with bilateral CIs). We came to the conclusion that deaf children who use bilateral devices have the opportunity to develop good speech perception skills in complex listening conditions. These abilities enable at least some of the children to develop age-equivalent verbal cognition skills.

Intersensory biasing occurs when cues in one sensory modality influence the perception of discrepant cues in another modality. Visual biasing of auditory stop consonant perception was examined in two related experiments in an attempt to clarify the role of hearing impairment on susceptibility to visual biasing of auditory speech perception. Fourteen computer-generated acoustic approximations of consonant-vowel syllables forming a /ba-da-ga/ continuum were presented for labeling as one of the three exemplars, via audition alone and in synchrony with natural visual articulations of /ba/ and of /ga/. Labeling functions were generated for each test condition showing the percentage of /ba/, /da/, and /ga/ responses to each of the 14 synthetic syllables. The subjects of the first experiment were 15 normal-hearing and 15 hearing-impaired observers. The hearing-impaired subjects demonstrated a greater susceptibility to biasing from visual cues than did the normal-hearing subjects. In the second experiment, the auditory stimuli were presented in a low-level background noise to 15 normal-hearing observers. A comparison of their labeling responses with those from the first experiment suggested that hearing-impaired persons may develop a propensity to rely on visual cues as a result of long-term hearing impairment. The results are discussed in terms of theories of intersensory bias.

Auditory Speech

A speech perception hierarchy has been developed and applied to assess the influence of cochlear implants and tactile aids on the acquisition of auditory, speech, and language skills in deaf children. Encouraging improvements were noted with both types of sensory aids at the detection level. The House 3M and Nucleus cochlear implant designs appear to offer advantages over the Tactaid II in providing ancillary speech perception cues to deaf children. Preliminary observations suggest that the multichannel cochlear implant design may be superior to the single-channel coding scheme.

Introduction A cochlear implant in adolescent patients with pre-lingual deafness is still a debatable issue. Objective The objective of this study is to analyze and compare the development of auditory speech perception in children with pre-lingual auditory impairment submitted to cochlear implant, in different age groups in the first year after implantation. Method This is a retrospective study, documentary research, in which we analyzed 78 reports of children with severe bilateral sensorineural hearing loss, unilateral cochlear implant users of both sexes. They were divided into three groups: G1, 22 infants aged less than 42 months; G2, 28 infants aged between 43 to 83 months; and G3, 28 older than 84 months. We collected medical record data to characterize the patients, auditory thresholds with cochlear implants, assessment of speech perception, and auditory skills. Results There was no statistical difference in the association of the results among groups G1, G2, and G3 with sex, caregiver education level, city of residence, and speech perception level. There was a moderate correlation between age and hearing aid use time, age and cochlear implants use time. There was a strong correlation between age and the age cochlear implants was performed, hearing aid use time and age CI was performed. Conclusion There was no statistical difference in the speech perception in relation to the patient's age when cochlear implant was performed. There were statistically significant differences for the variables of auditory deprivation time between G3 - G1 and G2 - G1 and hearing aid use time between G3 - G2 and G3 - G1.

Phonological Working Memory

Pierce, Genesee, Delcenserie, and Morgan have provided an innovative and thought-provoking juxtaposition of the putative role played by phonological working memory (PWM) in explaining individual and group differences among early internationally adopted (IA) children, deaf children with cochlear implants, simultaneous and sequential bilinguals, children who are learning sign languages, and children with otitis media. This novel comparison suggests that adequate exposure to phonology before 12 months of age is key in the development of improved PWM. Consequently, long-term linguistic advantages in vocabulary and learning of morphosyntax arise, but not advantages in other areas of higher cognition. One significant implication of the review is that although many intriguing links exist between language development and PWM, irrefutable conclusions elude the field as to the directionality of a causal relationship between phonological development, other linguistic development, and PWM. In this commentary, I should like to make the somewhat controversial proposal (Gathercole, 2006, and commentaries) that the evidence presented points to PWM being an epiphenomenon arising out of individual differences in the robustness and richness of phonological representations themselves. The authors hinted several times at the tantalizing relationship between phonology and PWM, but they do not articulate explicitly that PWM could be a redundant construct. I also offer some proposals as to how one might test this suggestion experimentally or in a corpus of child language.

PurposeWe sought to determine whether speech perception and language skills measured early after cochlear implantation in children who are deaf, and early postimplant growth in speech perception and language skills, predict long-term speech perception, language, and neurocognitive outcomes.MethodThirty-six long-term users of cochlear implants, implanted at an average age of 3.4 years, completed measures of speech perception, language, and executive functioning an average of 14.4 years postimplantation. Speech perception and language skills measured in the 1st and 2nd years postimplantation and open-set word recognition measured in the 3rd and 4th years postimplantation were obtained from a research database in order to assess predictive relations with long-term outcomes.ResultsSpeech perception and language skills at 6 and 18 months postimplantation were correlated with long-term outcomes for language, verbal working memory, and parent-reported executive functioning. Open-set word recognition was correlated with early speech perception and language skills and long-term speech perception and language outcomes. Hierarchical regressions showed that early speech perception and language skills at 6 months postimplantation and growth in these skills from 6 to 18 months both accounted for substantial variance in long-term outcomes for language and verbal working memory that was not explained by conventional demographic and hearing factors.ConclusionSpeech perception and language skills measured very early postimplantation, and early postimplant growth in speech perception and language, may be clinically relevant markers of long-term language and neurocognitive outcomes in users of cochlear implants.Supplemental materialshttps://doi.org/10.23641/asha.5216200
