The purpose of this longitudinal study was to predict /r/ acquisition using acoustic signal processing. 19 children, aged 5-7 with inaccurate /r/, were followed until they turned 8 or acquired /r/, whichever came first. Acoustic and descriptive data from 14 participants were analyzed. The remaining 5 children continued to be followed. The study analyzed differences in spectral energy at the baseline acoustic signals of participants who eventually acquired /r/ compared to that of those who did not acquire /r/. Results indicated significant differences between groups in the baseline signals for vocalic and postvocalic /r/, suggesting that the acquisition of certain allophones may be predictable. Participants’ articulatory changes made during the progression of acquisition were also analyzed spectrally. A retrospective analysis described the pattern in which /r/ allophones were acquired, proposing that vocalic /r/ and the postvocalic variant of consonantal /r/ may be acquired prior to prevocalic /r/, and /r/ followed by low vowels may be acquired before /r/ followed by high vowels, although individual variations exist.
The present study investigated the communicative characteristics of challenging behavior documented in children with Autism Spectrum Disorder (ASD), and how those behaviors changed as receptive and expressive language skills changed. Several years of the individual education plans (IEPs), behavior plans, and test scores of three male students from a small non- public school (NPS) were reviewed for this study. Challenging behaviors that served a communicative function showed some signs of diminishing as functional communication increased. While functional communication did show signs of increasing with the acquisition of expressive and receptive language the participants differed in their dependence on prompting to use functional communication in lieu of challenging behavior. Additionally, some of the challenging behaviors were rooted in a difficulty with self-regulation and stimming behavior and didn't appear to serve a communicative function. Given the significant impact challenging behaviors have on the quality life of the children with ASD and their families, more research is needed to better understand the connection between spontaneous and independent functional communication and duration to independent attention to task effects on challenging behavior.
The Development of the Strengthening Skills Program for Autistic Adults: Feasibility & Acceptability
The purpose of this study was to evaluate the quality of life in the participating families of the Babble Boot Camp. The Babble Boot Camp provides speech therapy for children with classic galactosemia starting as early as two months old. The child’s speech progress is evaluated along with other metrics such as parental and child stress levels and quality of life. In this study, the quality of life of the participants in the Babble Boot Camp was evaluated using the Pediatric Quality of Life questionnaire (Varni, 1998). A comparative study was conducted between mothers and fathers, families with children with classic galactosemia, and with typically developing children, and the effects of speech therapy earlier in a child’s life versus later. The questions looked into in this study were if mothers and fathers report different quality of life scores, if there is a correlation between the scores the children have for the quality of life and the scores the parents received for the quality of life, differences in quality of life scores of parents with children with classic galactosemia and parents with typically developing children, and if the quality of life scores of parents and children improve in the Babble Boot Camp. The main results were that mothers report a lower quality of life than fathers, mothers have a stronger correlation with their children in regards to their quality of life scores, parents with children with classic galactosemia have a lower quality of life scores than parents with typically developing children and parents and children who were in the group who received speech therapy from earlier have a higher quality of life scores than the late group.
