Evaluation Of The Efficiency Of And Preference For Analog Versus Mand Training On The Acquisition Of Mands For Children With Autism Spectrum Disorder, Melissa L. King
Evaluation Of The Efficiency Of And Preference For Analog Versus Mand Training On The Acquisition Of Mands For Children With Autism Spectrum Disorder, Melissa L. King
Theses & Dissertations
The present study provides a systematic replication of the Jennett, Harris, and Delmolino (2008) study comparing discrete trial instruction (DTI) and mand training on the acquisition of mands for children with autism spectrum disorder (ASD). An adapted alternating treatment design was implemented across three participants. Independent mands, variation in requested items, and duration of sessions were assessed across conditions. Generalization probes were conducted to assess generalization across communication partners (e.g., novel research assistants), along with a maintenance probe one-week post-training. Furthermore, a concurrent-chains arrangement was implemented to assess participants’ preference for teaching strategies. All participants reached mastery criterion quickest with …
A Comparison Of Measurement Systems To Score Sleep Disturbance For Children With Autism Spectrum Disorders, Aaron Lesser
A Comparison Of Measurement Systems To Score Sleep Disturbance For Children With Autism Spectrum Disorders, Aaron Lesser
Theses & Dissertations
Direct observation of children’s sleep disturbance in the home is critical to understanding child behavior while awake and determining qualitative features of the sleep environment, but obtaining these data from an in-home recorded video, second-by-second, is impractical in terms of scoring time because observers score when the child is asleep and awake. In Studies 1 and 2, we conducted an analog study to assess a motion-detection camera to determine whether it would be suitable to measure children’s sleep disturbance. In Study 3, we obtained in-home measures of sleep disturbance for three children with an autism spectrum disorder using a motion-detection, …
An Individualized Approach To Teach Greeting And Conversation Skills With Persons With Autism: Efficacy, Generalization, And Social Acceptability Outcomes, Stephanie A. Hood
An Individualized Approach To Teach Greeting And Conversation Skills With Persons With Autism: Efficacy, Generalization, And Social Acceptability Outcomes, Stephanie A. Hood
Theses & Dissertations
Individuals with an autism spectrum disorder commonly exhibit deficits in social skills, which can lead to a lack of friendships (Howlin, 2003) and underemployment (Shattuck et al., 2012). We selected social skills based on a parent interview and a direct assessment of three individuals’ conversation and greeting deficits. We taught the conversation and greeting skills using behavioral skills training and within-session prompting. We assessed generalization of the conversation and greeting skills across unfamiliar conversation partners and maintenance over time. We obtained parent responses on the social acceptability of their child’s social skills. A multiple baseline design across behaviors was used …

Motor-Skill Learning Is Dependent On Astrocytic Activity., Ragunathan Padmashri, Anand Suresh, Michael D. Boska, Anna Dunaevsky

Motor-skill learning induces changes in synaptic structure and function in the primary motor cortex through the involvement of a long-term potentiation- (LTP-) like mechanism. Although there is evidence that calcium-dependent release of gliotransmitters by astrocytes plays an important role in synaptic transmission and plasticity, the role of astrocytes in motor-skill learning is not known. To test the hypothesis that astrocytic activity is necessary for motor-skill learning, we perturbed astrocytic function using pharmacological and genetic approaches. We find that perturbation of astrocytes either by selectively attenuating IP3R2 mediated astrocyte Ca(2+) signaling or using an astrocyte specific metabolic inhibitor fluorocitrate (FC) results …
