Rescuing Age-Related Proteolysis Deficits With Methylene Blue, Shane E. Pullins
Rescuing Age-Related Proteolysis Deficits With Methylene Blue, Shane E. Pullins
Theses and Dissertations
The average lifespan is constantly increasing with the advent of new medical techniques, and age-related cognitive decline is becoming a prevalent societal issue. Even during healthy aging, humans and rats exhibit progressive deficits in episodic/declarative memory. In laboratory rats, age-related memory impairment can be assessed with trace fear conditioning (TFC). Recent research implicates ubiquitin proteasome system-mediated protein degradation in the synaptic plasticity supporting memory formation and retrieval. In rats, aging leads to decreased basal proteolytic activity in brain structures known to support the acquisition and retrieval of trace fear memories, and our preliminary data suggests activity-dependent proteasome activity declines in …
An Assessment Of Treatment Options For Pre-Existing Prompt Dependence In Children With Developmental Disabilities, Ella Gorgan
An Assessment Of Treatment Options For Pre-Existing Prompt Dependence In Children With Developmental Disabilities, Ella Gorgan
Theses and Dissertations
Prior research has focused on identifying effective strategies to prevent prompt dependence from occurring during the training of novel skills. This has been targeted in a variety of ways, including differential reinforcement, prompt fading, and allowing extended response intervals. Current literature has also indicated that the relative efficacy and efficiency of different prompting procedures may be idiosyncratic across learners, suggesting the potential benefit of an individualized assessment. The purpose of the current study was to extend the literature on prompt dependence by comparing interventions for skills for which four participants with developmental disabilities consistently engaged in correct responses following prompts …
An Evaluation Of Mand And Tact Assessment Procedures, Brittany Ann Leblanc
An Evaluation Of Mand And Tact Assessment Procedures, Brittany Ann Leblanc
Theses and Dissertations
There are many empirically validated interventions to establish vocal mands and tacts for children (e.g., Miguel, Carr, & Michael, 2002; Wallace, Iwata, & Hanley, 2006); however, the method for determining the most appropriate intervention for each individual is unclear. An assessment is one way to identify an effective intervention for a given individual. The purpose of the current study was to replicate and extend Bourret, Vollmer, & Rapp (2004) who evaluated an assessment to inform effective mand interventions for three boys with vocal mand deficits. In the first study, we replicated the full mand assessment as described by Bourret et …
Comparing The Efficacy And Efficiency Of Varying Task Interspersal Ratios, Sophie Claire Knutson
Comparing The Efficacy And Efficiency Of Varying Task Interspersal Ratios, Sophie Claire Knutson
Theses and Dissertations
Task interspersal (TI) is a procedural variation of discrete trial training that has been implemented with children with autism spectrum disorder (ASD) to facilitate the acquisition of novel skills, and may reduce problem behavior during instruction. The literature shows equivocal results regarding the efficiency of TI, but there is limited literature indicating the effects on level of problem behavior. The current study extended the literature on TI by comparing the efficacy and efficiency of varying TI ratios implemented in early intervention practices with children with ASD and related disorders on acquisition and levels problem behavior. The four ratios of mastered …
