Children who are identified with slow expressive language development (SELD) around the age of two are producing less than fifty intelligible words or no two word phrases. Current research suggests that some children with SELD outgrow their delay while others continue to develop long term language difficulties. The literature shows varied findings of short term recovery but long term deficits, and shifts in the specific expressive language deficits ~s the child with SELD matures and encounters increased language demands. Suggestions are found for a mix of monitoring and early intervention, in step with signs of readiness and dynamic assessments, to facilitate improved performance and hasten development, particularly in the areas of metalinguistics and narratives. This study attempted to support the recommendation of early intervention, particularly for those children with an initial greater severity levels of expressive communication delay at the age of two. The 24 male and seven female SELD subjects were part of the Portland Language Development Project, a longitudinal study. Intake was at two years, and placement in the Intervention (Rx) or No Intervention (No Rx) group was a result of follow-up information gathered from parents regarding enrollment in any early intervention services before the age of four: Using mean Developmental Sentence Scores (DSS) for four outcome points, 1-tests determined that no significant differences existed in the improvement of language production between the Rx and No Rx groups. Secondly, 1-tests showed no significant differences in the two group's initial severity levels, using the Expressive Communication sub-domain of the Vine~and Adaptive Behavior Scale (V ABS), as the measure of severity at intake. A non-significant trend of consistently higher actual mean DSS scores across all outcome points, and an actual lower mean Expressive Communication score on the V ABS at intake was noted for the Rx group. A significant difference was found in the mean intake ages of the two groups, with older toddlers falling into the Rx group. Research and clinical_ implications are discussed, including attention to the length, type and content of very early intervention services, effective initial and follow up assessments, and factors that favor recommending early intervention

The purpose of this study was to determine the relationship between the Peabody Picture Vocabulary Test-Revised, (PPVT-R) and receptive subtest of the Preschool Language Scale (PLS), and between the PPVT-R and the Test of Auditory Comprehension of Language-Revised (TACL-R), as well as determine how the tests compare in identifying children in need of further evaluation in the area of receptive language. The reasoning behind the goal of this study was to determine that if the three tests showed a strong, positive correlation and identified the same children as needing further assessment, then perhaps the test which was easier and shorter to administer (the PPVT-R) could be used with more confidence 2 as a quick, reliable screening tool of overall receptive language ability. In other words, if a child does poorly on the PPVT-R, one could assume that the child would most likely score below average on the other two tests also. Based on the results of this study, one cannot make this assumption.

The purpose of this investigation was to compare the results as recorded in mental ages of the PPVT and TACL when used with developmentally delayed children. One aspect was to observe how well the mean mental age from each test would compare with the mean mental age obtained from psychometric testing (WISC-R or SB-LM results). Another aspect was to determine how well the data from the PPVT and from the TACL would correlate with the psychometric testing results.

Teachers of students with autism spectrum disorders (ASD) often struggle to find effective instructional methods to use with their students on a daily basis. The characteristic verbal, social, and behavioral limitations of children with ASD make finding effective teaching methods difficult. Though some intensive intervention methods, such as discrete trial teaching (DTT), have numerous studies demonstrating their effectiveness with students with ASD, the required one-on-one format makes it impractical to use in a classroom setting on a regular basis. Direct Instruction (DI) appears in the literature as a promising intervention for students with developmental disabilities. One benefit of DI is that, unlike DTT and similar interventions, it can be implemented in a group format. This group format provides a practical alternative for classroom teachers to use with their students with ASD. This study utilized a multiple probe across behaviors design to further investigate the use of DI to teach high school students with ASD how to answer “wh-” questions. The researcher used the Science Research Associates (SRA) Reading Mastery language program, which is a DI program designed to develop language skills. Three participants between the ages of 15 and 17 participated in 20-25 minute instructional sessions four times a week for eight weeks. Data were collected on each participant’s accuracy in answering “wh-” questions during baseline, acquisition (teaching), and maintenance conditions. The results indicate that DI was effective in helping participants acquire the language skills necessary to accurately respond to “what,” “where," and “who” questions. Implications for small group language instruction for students with ASD and recommendations for future research are discussed. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2015. / FAU Electronic Theses and Dissertations Collection
