Is Pressure Stressful? The Impact Of Pressure On The Stress Response And Category Learning, Shannon L. Mccoy, Steven B. Hutchinson, Lauren Hawthorne, Brandon J. Cosley, Shawn W. Ell

We examine the basic question of whether pressure is stressful. We propose that when examining the role of stress or pressure in cognitive performance it is important to consider the type of pressure, the stress response, and the aspect of cognition assessed. In Experiment 1, outcome pressure was not experienced as stressful but did lead to impaired performance on a rule-based (RB) category learning task and not a more procedural information-integration (II) task. In Experiment 2, the addition of monitoring pressure resulted in a modest stress response to combined pressure and impairment on both tasks. Across experiments, higher stress appraisals …
Targeted Training Of The Decision Rule Benefits Rule-Guided Behavior In Parkinson’S Disease, Shawn W. Ell
Targeted Training Of The Decision Rule Benefits Rule-Guided Behavior In Parkinson’S Disease, Shawn W. Ell
Psychology Faculty Scholarship
The impact of Parkinson’s disease (PD) on rule-guided behavior has received considerable attention in cognitive neuroscience. The majority of research has used PD as a model of dysfunction in fronto-striatal networks, but very few attempts have been made to investigate the possibility of adapting common experimental techniques in an effort to identify the conditions that are most likely to facilitate successful performance. The present study investigated a targeted training paradigm designed to facilitate rule learning and application using rule-based categorization as a model task. Participants received targeted training in which there was no selective-attention demand (i.e., stimuli varied along a …

Background: Prenatal exposure to ethanol and later socially mediated exposure predicts ethanol intake in human adolescents. Animal rat models indicate that brief interactions with an ethanol-intoxicated peer result in heightened preference for ethanol odor and ethanol intake. Methods: This study assessed preference for ethanol odor in adolescent male rats (observers) following social interaction with an ethanol intoxicated peer (demonstrators) as a function of prenatal ethanol exposure (gestational days 17-20, 1.0 g/kg, intragastric). Social behavior and locomotion during social interaction was also measured. Results: Social investigation was greater in observers that interacted with an intoxicated demonstrator in comparison to those that …

Because juveniles can now be registered as sex offenders, we conducted a pilot study to investigate awareness of these policies and sexual behavior histories in a convenience sample of 53 young adults (ages 18 to 23, 79% women). These preliminary data revealed that 42% percent of participants were unaware that youth under the age of 18 can be registered as sex offenders, and when informed that they can be, participants were unaware of the breadth of adolescent sexual behavior that warrants registration. Furthermore, those unaware of juvenile registration policies, compared to those who were aware, were marginally more likely to …
