Professional Education To Reduce Provider Stigma Toward Harm Reduction And Pharmacotherapy, Sandra H. Sulzer, Suzanne Prevedel, Tyson Barrett, Maren Wright Voss, Cassandra Manning, Erin Fanning Madden

Extension Research

Aims: A novel professional training was developed to reduce stigma toward harm reduction and pharmacotherapy for substance use disorders.

Methods: The training was delivered over three sessions to n = 147 health professionals in Utah between 2019 and 2020, including n = 40 substance use disorder treatment professionals. Pre and post-training survey measures provided evaluation information on knowledge, attitudes, and planned action regarding harm reduction and pharmacotherapy. Items were grouped into a stigma score, and multilevel modeling, regression analyses, and McNemar tests were used to quantify changes in overall stigma toward harm reduction interventions both before and after the training. …

Priming Of Grasping Muscles When Viewing A Safety Handle Is Diminished With Age, David A.E. Bolton, Sarah E. Schwartz, Manhoud Mansour, Garrett Rydalch, Douglas W. Mcdannald

Merely viewing objects within reachable space can activate motor cortical networks and potentiate movement. This holds potential value for smooth interaction with objects in our surroundings, and could offer an advantage for quickly generating targeted hand movements (e.g. grasping a support rail to maintain stability). The present study investigated if viewing a wall-mounted safety handle resulted in automatic activation of motor cortical networks, and if this effect changes with age. Twenty-five young adults (18–30 years) and seventeen older adults (65+ years) were included in this study. Single-pulse, transcranial magnetic stimulation was applied over the motor cortical hand representation of young …

Inactivation Of The Medial-Prefrontal Cortex Impairs Interval Timing Precision, But Not Timing Accuracy Or Scalar Timing In A Peak-Interval Procedure In Rats, Catalin V. Buhusi, Marcelo B. Reyes, Cody-Aaron Gathers, Sorinel A. Oprisan, Mona Buhusi

Psychology Faculty Publications

Motor sequence learning, planning and execution of goal-directed behaviors, and decision making rely on accurate time estimation and production of durations in the seconds-to-minutes range. The pathways involved in planning and execution of goal-directed behaviors include cortico-striato-thalamo-cortical circuitry modulated by dopaminergic inputs. A critical feature of interval timing is its scalar property, by which the precision of timing is proportional to the timed duration. We examined the role of medial prefrontal cortex (mPFC) in timing by evaluating the effect of its reversible inactivation on timing accuracy, timing precision and scalar timing. Rats were trained to time two durations in a …

The Role Of Multiple Internal Timekeepers And Sources Of Feedback On Interval Timing, Breanna E. Studenka, Daisha L. Cummins, Megan A. Pope

Kinesiology and Health Science Faculty Publications

The aim of this experiment was to document the role of multiple internal clock mechanisms and external sources of temporal feedback on reducing timing variability when two fingers tap instead of one (a phenomenon known as the bimanual advantage). Previous research documents a reduction in timed interval variability when two effectors time instead of one. In addition, interval variability decreases with multiple sources of feedback. To date, however, no research has explored the separate roles of feedback and internal timing on the bimanual advantage. We evaluated the bimanual advantage in a task that does not utilise an internal clock (circle …
