Purpose: The purpose of this study was to find out if children who are deaf and hard of hearing (DHH), particularly those without substantially delayed language, appear to be at risk for overreporting of inattentive and hyperactive behaviors and if attention-deficit/hyperactivity disorder (ADHD) measures are influenced by the presence of language-based items, by child language skills, and by child and parent report of fatigue.

Method: This study included 24 children with typical hearing, 13 children with hearing aids (HA), and 16 children with cochlear implants (CI) in second through sixth grade. Parents of children in each group completed a measure reporting on inattentive and hyperactive behaviors, social and academic outcomes, and general fatigue for their child.

Guidelines created by the American Academy of Pediatrics ([AAP], 2010) and the Joint Committee on Infant Hearing ([JCIH], 2019) were designed to aid in the early identification of infant hearing loss. Despite these guidelines, a quarter of children who do not pass their initial screening are lost to the follow-up process and many more do not receive care in line with the 1-3-6 guidelines (Centers for Disease Control and Prevention [CDC], 2018; JCIH, 2019). To acquire more information about the experiences of families and identify specific barriers to timely diagnosis and intervention, interviews were conducted with 13 parents of children who are deaf or hard of hearing whose children were enrolled in a larger longitudinal study.

This study compared preschool spoken language outcomes for children with hearing loss who met Early Hearing Detection and Intervention (EHDI) guidelines to those who did not, as well as to compare outcomes for those who met current EHDI guidelines to those who met earlier benchmarks. Finally, the predictive role of meeting each component of the guidelines was evaluated relative to language outcomes. Children who met the EHDI guidelines had higher language scores than those who did not; however, there was no difference between children who met the current guidelines and those who met the earlier benchmarks.

Purpose: The purpose of this study is to evaluate the effects of switching from in-person assessment to virtual assessment during the COVID-19 pandemic on the growth trajectories of children with hearing loss who are learning spoken language.

Method: Sixty-eight children with typical hearing, 44 children with cochlear implants, and 47 children with hearing aids were assessed with a norm-referenced measure of receptive vocabulary, a criterion-referenced measure of phonological awareness, and a criterion-referenced measure of conceptual print knowledge at least 4 times, at 6-month intervals, between the ages of 4 and 6 years. Of those participants, 26 children with typical hearing, 13 children with cochlear implants, and 13 children with hearing aids entered virtual testing as a result of the COVID-19 pandemic.

The purpose of this study was to consider how living in an area that qualifies for a rural health grant interacts with a child's hearing status to affect early language and literacy development. Four-year-old children with hearing aids (n = 45), cochlear implants (n = 47), and with typical hearing (n = 66) completed measures of spoken language knowledge and of emergent literacy skills as part of a larger longitudinal investigation. A significant interaction effect between location (rural or urban/suburban) and amplification group was detected for letter knowledge: children with hearing aids exhibit a performance that is particularly affected by rural location.

Purpose The COVID-19 pandemic has necessitated a quick shift to virtual speech-language services; however, only a small percentage of speech-language pathologists (SLPs) had previously engaged in telepractice. The purpose of this clinical tutorial is (a) to describe how the Early Language and Literacy Acquisition in Children with Hearing Loss study, a longitudinal study involving speech-language assessment with children with and without hearing loss, transitioned from in-person to virtual assessment and (b) to provide tips for optimizing virtual assessment procedures. Method We provide an overview of our decision making during the transition to virtual assessment.

The purpose of this study was (a) to compare the single-word spelling performance of first graders across four groups that varied by speech and language status; and (b) to determine the linguistic predictors of first-grade spelling for children with speech and/or language impairment compared to children with typical development. First grade children ( = 529) completed measures of spelling, early word reading, expressive vocabulary, phonological awareness, and morphosyntactic knowledge. Children with language impairment, with or without speech impairments, demonstrated lower spelling performance than children with typical development; children with speech impairment only did not differ from children with typical development.

Purpose Spelling is a skill that relies on an individual's linguistic awareness, the ability to overtly manipulate language. The ability to accurately spell is important for academic and career success into adulthood. The spelling skills of adults have received some attention in the literature, but there is limited information regarding which approach for analyzing adults' spelling is optimal for guiding instruction or intervention for those who struggle.

Purpose The purpose of this study was to characterize the lexical-morphological networks of children with specific language impairment (SLI) compared to children with typical language by analyzing responses on a morphological derived form production task. Method School-age children with SLI ( = 32) and peers with typical language ( = 40) completed an oral cloze derived form production task (Carlisle, 2000). On this task, children were expected to complete verbally presented sentences with a derived form of a provided morphological stem.

Purpose: Because children with hearing loss experience difficulty in developing word decoding and spelling skills, effective phonological awareness instruction for this population is vital. Children with hearing loss are often delayed in their development of phonological awareness compared to peers with normal hearing; however, the developmental progression appears to be the same for both groups of children. Some modifications to typical phonological awareness instruction are warranted for this population.
