Responses of six severely language delayed (SLD) children were obtained on three measures of central auditory processing and one measure of language proficiency. The results of these measures were compared to the results obtained from six normal-hearing children, matched in age and Performance IQ on the WISC-R. The 12 children were tested with the Pitch Pattern Sequence Test (PPST), the Dichotic Digit Tests (DDT), and the Pediatric Speech Intelligibility Test (PSI). Differences in the central auditory abilities as well as the history of each child were presented in .a case study format. The results of the history information demonstrated no unusual problems among these 12 subjects. Ten out of 12 subjects demonstrated abnormal results on at least one measure of the central auditory battery.

Identification and selection of a speech-language caseload in the school setting can be a challenging task. The initial stages of caseload selection are usually in the form of a screening procedure. Although speech-language information is gathered at that time, information about its relationship to each student's academic status is usually not obtained. Such information would be useful in a setting that requires the provision of special education services to be justified from a basis of academic need.

It is obvious that the effects of speaking rate on the ability of aphasic children to comprehend verbal material has not been extensively researched. The studies cited above suggest that an increase in rate adversely affects comprehension by various subjects, while a decrease in rate may improve comprehension by certain subjects. Therefore, the present study attempted to examine the effects of the rate at which an auditory stimulus is presented to aphasic and normal children.

Background. Autism spectrum disorder (ASD) is characterized by persistent difficulties with social communication (American Psychiatric Association, 2013). Due to the high prevalence of ASD there’s a significant demand for services to support these individuals and the involvement of caregivers is considered a crucial element of effective early intervention for young children with developmental disabilities (Siller & Morgan, 2018). The Incredible Years ® is an evidence-based behavioral parent training program with a large body of research demonstrating its efficacy with enhancing positive parenting practices during parent-child interactions for children with behavior problems (Menting et al., 2013). The program is built on the foundational concept of child-led free play. Recently, the program has been adapted for families with young children with developmental disabilities, Incredible Years Program for Autism Spectrum Disorder and Language Delays Ages 2-5® (IY-ASLD). IY-ASLD aims to help parents learn developmentally-attuned language and play strategies to effectively engage with toddlers with ASD or social communication delays. There are few published evaluations of IY-ASLD currently. However, the findings from pilot studies are promising in terms of the feasibility of implementation, with high levels parent satisfaction and attendance. The present study uses data from a pilot study of the IY-ASLD program (N=17), which was adapted to telehealth during COVID-19 pandemic with the assistance of program developer. This dissertation contributes to an emerging body of research by evaluating the IY-ASLD program in a community setting. By examining IY’s group treatment model in a telehealth format, we also gain valuable insight about virtual parenting interventions, which have the potential to significantly expand treatment to more families. Methods. Families were recruited from a specialized early intervention and preschool program that utilizes an Applied Behavior Analysis approach to education. Seventeen (N=17) parent-child dyads from the school enrolled in the program. All or virtually all children referred to this school by their school district are at-risk for or have been diagnosed with ASD. All of the children had an IEP or IFSP with mandated speech services, 71% of the children met criteria for ASD (N = 12) on the Childhood Autism Rating Scale-2-SF, and 2/3 of the sample had adaptive behavior composites below a standard score of 70 on the Vineland Adaptive Behavior Scales- Third Edition Comprehensive Teacher Form (Sparrow et al., 2016) at baseline. The parent participants, all mothers, began and completed a 12-week IY-ASLD telehealth intervention delivered over HIPAA protected Zoom. Mothers were from diverse backgrounds (41% non US born), well-educated (94% college graduate) and had a high median household income. Data from participants was gathered through questionnaires administered to parents, child-functioning measures completed prior to treatment by school personnel, and parent-child interactions videos recorded in the home at pre-, mid-, and post-treatment across a 12-week IY-ASLD intervention. Primary outcome variables were parent verbal behaviors during 5-minute parent-child free play sessions recorded at each time point. Each vocal utterance during free play sessions was coded for function, consistent with the parenting skills that were targeted in the IY-ASLD program (e.g., reducing commands, questions, and corrections, increasing descriptive narration and praise, following the child’s lead). The independent variables were time and dosage (minutes spent in treatment) and the moderators were child’s functioning levels (special education teacher/clinician ratings on the Vineland Adaptive Behavioral Scales- Third Edition (Vineland-3, Sparrow et al., 2016) and Childhood Autism Rating Scale, Second Edition- Standard Form (CARS2= ST, Schloper et al., 2010). Results. Mothers in the IY-ASLD program significantly decreased the ratio of parent-directed language and increased the ratio of child-directed language they used during the free play sessions with large effect sizes and most of the change occurring in the mid-to-post interval. Descriptive statements (tacts) also increased significantly for all participants with large effect sizes; the number of directive or question statements (mands) decreased with medium effect sizes, though the results were not significant. Dosage was not a significant predictor of outcomes at post-treatment when pre-treatment parenting behaviors were taken into consideration, possibly due to low variability in attendance. When child level was analyzed as a moderator, there were large effect sizes for the observed changes in tacts, mands, and overall ratio of child-directed language when children were divided into ASD vs No ASD groups, but small effect sizes when looking at low vs high adaptative behavior groups. There was a significant interaction effect between change in parent language over time and ASD severity of the child; parents of children with ASD did not significantly reduce the number of mands over time, while parents of children without ASD significantly reduced their number of mands over time. This research provides support for a full-RCT of IY-ASLD in this setting, suggesting that the intervention promotes maternal use of child-directed language, particularly for children with language delays as opposed to those with more severe symptoms of ASD. Interventions such as IY-ASLD may help empower parents of preschoolers with disabilities with strategies to facilitate more rewarding free play interactions at home.

I tested the effects of an observational intervention on observing responses, denial responses, and audience appropriate behaviors in 9 preschool children with developmental and language delays. The participants were 8 males and 1 female aged 3-5 years, who were selected from a preschool program that implemented a behavior analytic approach to all instruction. All participants had fluent listener and speaker repertoires and emitted mands, tacts, and sequelics with adults. The children were selected to participate because they displayed little to no awareness of, or interactions with their peers during free play and social settings. I conducted probes for a) peer observing responses, b) responses to denial of non-preferred stimuli being delivered to peers, c) social initiations to peers, d) responses to peers’ social initiations, and e) other socially appropriate behaviors. Pre-intervention probes showed that all participants emitted low peer observing responses in free play settings, and did not consistently initiate or reciprocate peer interactions across different social settings. Five out of nine participants emitted responses to denial prior to the intervention. The independent variable was an observational intervention using non-preferred stimuli and a denial condition that was used in prior studies to establish conditioned reinforcement by observation. The participant and peer confederate sat side-by-side at a table, and were separated by an opaque partition. They were both presented with a performance task. The participant observed the peer confederate receive the non-preferred stimuli but could not observe the peer’s responses to the task. The intervention continued until the participants emitted responses to denial of the non-preferred stimuli across two sessions. Post-intervention data suggest that peer observing responses in free play settings, as well as audience appropriate behaviors in social settings increased as a function of the observational intervention in 8 out of 9 participants. Responses to the denial of non-preferred stimuli delivered to a peer increased in 4 out of 4 participants who did not respond during pre-intervention probes.

The purpose of this study was to determine if an association exists among the diagnosis of speech-language impairments (SLI) and the diagnoses of learning disabilities (LD) and/or attention deficit hyperactivity disorder (ADHD) in a school-aged population of children referred to a Learning Disorders Clinic (LDC) because of academic underachievement and/or behavior problems. The two research questions asked in this study are: (a) What percentage of students diagnosed with SLI have a concomitant diagnosis of LD and/or ADHD? and (b) Is there an association among the diagnosis of SLI and the diagnoses of LD and/or ADHD? A sample of 94 subjects was obtained from review of 291 LDC records of children ref erred and diagnosed during the years 1989-1992. The subjects were grouped into eight categories by diagnosis, that is, (a) SLI, (b) SLI/LD, (c) SLI/ADHO, (d) SLI/LO/ADHD, (e) no diagnosis of SLI/LO/AOHD, (f) LO, (g) ADHD, and (h) LD/ADHD. The obtained Chi square value was not statistically significant at a .OS alpha level. Thus, the null hypothesis: there will be no association among the diagnosis of SLI and the diagnoses of LO and/or ADHD, could not be rejected. In this sample, however, 85% of the children diagnosed with SLI had a concomitant diagnosis of LD and/or ADHD, and 70% with no SLI diagnosis were diagnosed with LD and/or ADHD. The overlapping nature of the disorders of SLI, LD, and ADHD is noted. The definitions of SLI and LO demonstrate how enmeshed language and learning problems are. One inference from this study is that as children grow older, their language deficits are recognized in the context of a learning disorder.

Much advice has been published in the last 40 years that has attempted to aid speech-language pathologists in choosing language assessment tools (e.g., Danwitz, 1981 & Darley, 1979 ). Questions have arisen about what tests are actually being used in public schools and the reasons for those tests being used over other tests. The data bank of information is minimal in this area as only one study has appeared in the literature in which Wilson, Blackmon, Hall, & Elcholtz, (1991), conducted a State survey of currently used language assessment instruments. The primary research question to be answered was: What methods of language assessment are being used in Oregon? Secondary questions to be answered were: (a) What factors influence the selection and use of the chosen procedures?, (b) What are the dates of development of the tests used most frequently, (c) By what means do the public school clinicians keep themselves current with new trends and information in the field? There were 567 questionnaires mailed out to Oregon Speech-Language Pathologists who worked in the public school setting and served children 4-9 years of age. Of the 297 respondees, only 4 reported not using any formal instruments for language assessment. Results show 9 main standardized tests were used for measuring expressive language by the majority of the respondents. Listed in order of frequency of use, they are: TOLD, EOWPVT, WORD test, CELF, LPT, SPELT, ASSET, TOPS, and the PLS. For receptive language, also in order of frequency of use, the 1 O main tests were as follows: PPVT, TOLD, CELF, TACL, ASSET, BOEHM, PLS, ROWPVT, BRACKEN, and the LPT. Factors that influenced the selection and use of specific tests included: personal experience; ease of administration; time restraints; budgets and availability of tests and district protocols for assessments. Dates of publication, new and revisions, for both the expressive and receptive tests used ranged from 1983 - 1990. At the time of this survey, the main ways that clinicians were keeping themselves current for new tests on the market were word of mouth from associates, inservices on new tests, and reading new information in journals.
