Conditional Use of a Request for Assistance: Considering Generalization / Joe REICHLE in Focus on Autism and Other Developmental Disabilities, 33-2 (June 2018)
[article]
Titre : Conditional Use of a Request for Assistance: Considering Generalization Type de document : Texte imprimé et/ou numérique Auteurs : Joe REICHLE, Auteur ; Breanne J. BYIERS, Auteur ; Amanda REEVE, Auteur Article en page(s) : p.80-90 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorder (ASD) frequently exhibit generalization errors, but many instructional programs fail to address this deficit. Generalization errors encompass when the learner should extend the use of a newly taught behavior to other contexts but does not (under-generalization), as well as when he or she should not use the newly established behavior in new contexts but does (over-generalization). This study was designed to evaluate the generalization errors of a preschooler with ASD. Following an intervention in which the participant was taught to request assistance with difficult tasks using a continuous reinforcement schedule, generalization gradients across levels of task difficulty were implemented to examine patterns of generalization. Initial results showed over-generalization of assistance requests and corresponding reductions in independent (the absence of any instructional prompts) task completion across all levels of task difficulty. A final phase involving competing schedules of reinforcement for assistance requests and independent work with video modeling led to improved conditional use of assistance requests. Implications for teaching conditional use of assistance requests are discussed.

Titre : The feasibility of using actigraphy to characterize sleep in Rett syndrome Type de document : Texte imprimé et/ou numérique Auteurs : A. M. MERBLER, Auteur ; Breanne J. BYIERS, Auteur ; J. J. GARCIA, Auteur ; T. J. FEYMA, Auteur ; F. J. SYMONS, Auteur Article en page(s) : p.8 Langues : Anglais (eng) Mots-clés : Actigraphy Mecp2 Rett syndrome Sleep Index. décimale : PER Périodiques Résumé : BACKGROUND: Rett syndrome (RTT) is a neurodevelopmental disorder primarily caused by mutations in the MECP2 gene. Sleep problems are reported by the majority of caregivers of individuals with RTT. METHODS: The present study aimed to replicate and extend previous work about the feasibility of measuring sleep with an actigraph device in a sample of girls with clinically diagnosed RTT (N = 13, mean age = 9 years, 5 months). Participants wore an actigraph device day and night for seven consecutive days. Materials also included a parent-completed sleep diary to measure bedtime, duration of nighttime sleep, and daytime sleep, and the Child Sleep Habit's Questionnaire (CSHQ). RESULTS: The means for the sample as measured by actigraphy were 492.3 min (SD = 47.3) of total night sleep (TNS), 76.0% (SD = 6.7) sleep efficiency, 86.0 min (SD = 34.2) of wake after sleep onset, and 46.1 min (50.8) of sleep when parents reported a nap occurring. Parents reported 589.7 min (SD = 53.6) of TNS, 15.9 min (SD = 12.0) of WASO, and 93.6 min (SD = 66.8) of daytime sleep according to sleep diaries, with all parents reporting at least one nap during the week. Relations were found between sleep characteristics and seizure status and CSHQ total scores. No age-related changes were observed for any sleep characteristic, regardless of collection method. Five of nine participants above the cutoff score on the CSHQ indicate the need for further evaluation for a sleep disorder. CONCLUSIONS: Overall, actigraphy was feasible in this community-based sample of girls with RTT. The results replicated some aspects of previous studies of sleep in RTT (e.g., no age-related changes in total nighttime sleep or efficiency). Some participants met the American Academy of Sleep Medicine guidelines for recommended total sleep time, with others showing too much or too little sleep. Each of the three methods for describing sleep presented its own advantages and challenges. Future work should be prospectively designed, validate the use of actigraphy in this population, and include a typically developing comparison sample to improve the precision of our understanding of sleep in RTT.
