    Purpose The purpose of this study was to determine whether deficits in executive functioning (EF) in children with cochlear implants (CIs) emerge as early as the preschool years. Method Two groups of children ages 3 to 6 years participated in this cross-sectional study: 24 preschoolers who had CIs prior to 36 months of age and 21 preschoolers with normal hearing (NH). All were tested on normed measures of working memory, inhibition-concentration, and organization-integration. Parents completed a normed rating scale of problem behaviors related to EF. Comparisons of EF skills of children with CIs were made to peers with NH and to published nationally representative norms. Results Preschoolers with CIs showed significantly poorer performance on inhibition-concentration and working memory compared with peers with NH and with national norms. No group differences were found in visual memory or organization-integration. When data were controlled for language, differences in performance measures of EF remained, whereas differences in parent-reported problems with EF were no longer significant. Hearing history was generally unrelated to EF. Conclusions This is the first study to demonstrate that EF deficits found in older children with CIs begin to emerge as early as preschool years. The ability to detect these deficits early has important implications for early intervention and habilitation after cochlear implantation.

    Family Environment in Children With Hearing Aids and Cochlear Implants: Associations With Spoken Language, Psychosocial Functioning, and Cognitive Development
    (Wolters Kluwer, 2020) Frush Holt, Rachael; Beer, Jessica; Kronenberger, William G.; Pisoni, David B.; Lalonde, Kaylah; Mulinaro, Lindsay; Otolaryngology -- Head and Neck Surgery, School of Medicine
    Objectives: To examine differences in family environment and associations between family environment and key speech, language, and cognitive outcomes in samples of children with normal hearing and deaf and hard-of-hearing (DHH) children who use hearing aids and cochlear implants. Design: Thirty families of children with normal hearing (n = 10), hearing aids (n = 10), or cochlear implants (n = 10) completed questionnaires evaluating executive function, social skills, and problem behaviors. Children's language and receptive vocabulary were evaluated using standardized measures in the children's homes. In addition, families were administered a standardized in-home questionnaire and observational assessment regarding the home environment. Results: Family environment overall was similar across hearing level and sensory aid, although some differences were found on parental responsivity and physical environment. The level of supportiveness and enrichment within family relationships accounted for much of the relations between family environment and the psychosocial and neurocognitive development of DHH children. In contrast, the availability of objects and experiences to stimulate learning in the home was related to the development of spoken language. Conclusions: Whereas broad characteristics of the family environments of DHH children may not differ from those of hearing children, variability in family functioning is related to DHH children's at-risk speech, language, and cognitive outcomes. Results support the importance of further research to clarify and explain these relations, which might suggest novel methods and targets of family-based interventions to improve developmental outcomes.

    Neurocognitive Risk in Children With Cochlear Implants
    (American Medical Association, 2014-07) Kronenberger, William G.; Beer, Jessica; Castellanos, Irina; Pisoni, David B.; Miyamoto, Richard T.; Psychiatry, School of Medicine
    IMPORTANCE Children who receive a cochlear implant (CI) for early severe to profound sensorineural hearing loss may achieve age-appropriate spoken language skills not possible before implantation. Despite these advances, reduced access to auditory experience may have downstream effects on fundamental neurocognitive processes for some children with CIs. OBJECTIVE To determine the relative risk (RR) of clinically significant executive functioning deficits in children with CIs compared with children with normal hearing (NH). DESIGN, SETTING, AND PARTICIPANTS In this prospective, cross-sectional study, 73 children at a hospital-based clinic who received their CIs before 7 years of age and 78 children with NH, with average to above average mean nonverbal IQ scores, were recruited in 2 age groups: preschool age (age range, 3–5 years) and school age (age range, 7–17 years). No children presented with other developmental, cognitive, or neurologic diagnoses. INTERVENTIONS Parent-reported checklist measures of executive functioning were completed during psychological testing sessions. MAIN OUTCOMES AND MEASURES Estimates of the RR of clinically significant deficits in executive functioning (≥ 1 SDs above the mean) for children with CIs compared with children with NH were obtained based on 2 parent-reported child behavior checklists of everyday problems with executive functioning. RESULTS In most domains of executive functioning, children with CIs were at 2 to 5 times greater risk of clinically significant deficits compared with children with NH. The RRs for preschoolers and school-aged children, respectively, were greatest in the areas of comprehension and conceptual learning (RR [95% CI], 3.56 [1.71–7.43] and 6.25 [2.64–14.77]), factual memory ( 4.88 [1.58–15.07] and 5.47 [2.03–14.77]), attention (3.38 [1.03–11.04] and 3.13 [1.56–6.26]), sequential processing (11.25 [1.55–81.54] and 2.44 [1.24–4.76]), working memory (4.13 [1.30–13.06] and 3.64 [1.61–8.25] for one checklist and 1.77 [0.82–3.83] and 2.78 [1.18–6.51] for another checklist), and novel problem-solving (3.93 [1.50–10.34] and 3.13 [1.46–6.67]). No difference between the CI and NH samples was found for visual-spatial organization (2.63 [0.76–9.03] and 1.04 [0.45–2.40] on one checklist and 2.86 [0.98–8.39] for school-aged children on the other checklist). CONCLUSIONS AND RELEVANCE A large proportion of children with CIs are at risk for clinically significant deficits across multiple domains of executive functioning, a rate averaging 2 to 5 times that of children with NH for most domains. Screening for risk of executive functioning deficits should be a routine part of the clinical evaluation of all children with deafness and CIs.
