Specialized Late Cingulo-Opercular Network Activation Elucidates The Mechanisms Underlying Decisions About Ambiguity, Jordan E. Pierce, Nathan M. Petro, Elizabeth Clancy, Caterina Gratton, Steven E. Petersen, Maital Neta

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Cortical task control networks, including the cingulo-opercular (CO) network play a key role in decision-making across a variety of functional domains. In particular, the CO network functions in a performance reporting capacity that supports successful task performance, especially in response to errors and ambiguity. In two studies testing the contribution of the CO network to ambiguity processing, we presented a valence bias task in which masked clearly and ambiguously valenced emotional expressions were slowly revealed over several seconds. This slow reveal task design provides a window into the decision-making mechanisms as they unfold over the course of a trial. In …

Core Neuropsychological Measures For Obesity And Diabetes Trials: Initial Report, Kimberlee D'Ardenne, Cary R. Savage, Dana Small, Uku Vainik, Luke E. Stoeckel

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Obesity and diabetes are known to be related to cognitive abilities. The Core Neuropsychological Measures for Obesity and Diabetes Trials Project aimed to identify the key cognitive and perceptual domains in which performance can influence treatment outcomes, including predicting, mediating, and moderating treatment outcome and to generate neuropsychological batteries comprised of well-validated, easy-to-administer tests that best measure these key domains. The ultimate goal is to facilitate inclusion of neuropsychological measures in clinical studies and trials so that we can gather more information on potential mediators of obesity and diabetes treatment outcomes. We will present the rationale for the project and …

Lung Cancer Screening In A Community Setting: Characteristics, Motivations, And Attitudes Of Individuals Being Screened, Margaret M. Byrne, Sarah E. Lillie, Jamie L. Studts

Behavioral Science Faculty Publications

We describe the characteristics of individuals being screened in community settings including factors influencing screening decisions and the level of information sought prior to screening. Individuals from two community-based radiology clinics (N = 27) were surveyed after screening. Screening efficacy and salience were the most important factors in screening decisions, whereas healthcare provider recommendations were rated not important. Half of participants reported no or little conversation about screening with their primary care provider, and 61.5 percent had not sought any information on screening. Individuals being screened in a community setting are unlikely to have sufficient information for an informed …

Uncertainty And Competing Priorities In Shared Clinical Decision-Making, Dennis J. Baumgardner

Dennis J. Baumgardner, MD

In this issue introduction, the editor-in-chief of Journal of Patient-Centered Research and Reviews observes that a connecting thread among the articles published therein is an element of uncertainty among patients and clinicians. Competing priorities for the patient also may be present. Several approaches to overcoming these prevalent conflicts to delivery of better health care have been proposed, the most important of which may be clinicians embracing a will to practice shared decision-making.

Cocaine Choice: A Novel Procedure For Investigating Neuronal Activation Mediating Cocaine Preference, Jonathan Jenn-Sheng Chow

Theses and Dissertations--Psychology

Cocaine use disorder is a significant health problem, negatively impacting individuals afflicted. While preclinical self-administration research has provided invaluable insight into the neurobehavioral mechanisms that underlie cocaine abuse, cocaine use outside of the laboratory occurs within an environment where other goods are also available ubiquitously. Although there is an ever-increasing literature investigating drug vs. non-drug choice in rodent models and how alternative goods can compete with the subjective value of cocaine, the neurobiological mechanisms that are associated with cocaine preference remains largely unknown. Additionally, current drug vs. non-drug choice studies use procedures that confound preference with intake, such that preference …

Trait Anxiety And Economic Risk Avoidance Are Not Necessarily Associated: Evidence From The Framing Effect, Ruolei Gu, Runguo Wu, Lucas S. Broster, Yang Jiang, Rui Xu, Qiwei Yang, Pengfei Xu, Yue-Jia Luo

Behavioral Science Faculty Publications

According to previous literature, trait anxiety is related to the tendency to choose safety options during risk decision-making, that is, risk avoidance. In our opinion, anxious people’s risk preference might actually reflect their hypersensitivity to emotional information. To examine this hypothesis, a decision-making task that could elicit the framing effect was employed. The framing effect indicates that risk preference could be modulated by emotional messages contained in the description (i.e., frame) of options. The behavioral results have showed the classic framing effect. In addition, individual level of trait anxiety was positively correlated with the framing effect size. However, trait anxiety …

Stability Of Older Adult Reaction Time In An Impulse Control Task , Elizabeth R. Paitel, Gretchen Stutz, Jonathan Carroll

Student Presentations

The current study employed an impulse control decision-making task to investigate the effects of social context on decision-making in a sample of older adults (65+) and younger adults (18-22).

Linking Brain Electrical Signals Elicited By Current Outcomes With Future Risk Decision-Making, Dandan Zhang, Ruolei Gu, Lucas S. Broster, Yang Jiang, Wenbo Luo, Jian Zhang, Yue-Jia Luo

Behavioral Science Faculty Publications

The experience of current outcomes influences future decisions in various ways. The neural mechanism of this phenomenon may help to clarify the determinants of decision-making. In this study, thirty-nine young adults finished a risky gambling task by choosing between a high- and a low-risk option in each trial during electroencephalographic data collection. We found that risk-taking strategies significantly modulated mean amplitudes of the event-related potential (ERP) component P3, particularly at the central scalp. The event-related spectral perturbation and the inter-trial coherence measurements of the independent component analysis (ICA) data indicated that the “stay” vs. “switch” electrophysiological difference associated with subsequent …

It’S Not About The Money: The Role Of Preferences, Cognitive Biases And Heuristics Among Professional Athletes, Michael Mccann

Law Faculty Scholarship

Professional athletes are often regarded as selfish, greedy, and out-of-touch with regular people. They hire agents who are vilified for negotiating employment contracts that occasionally yield compensation in excess of national gross domestic products. Professional athletes are thus commonly assumed to most value economic remuneration, rather than the love of the game or some other intangible, romanticized inclination.

Lending credibility to this intuition is the rational actor model, a law and economic precept which presupposes that when individuals are presented with a set of choices, they rationally weigh costs and benefits, and select the course of action that maximizes their …

Varied Definitions Of Risk Related To Sensation Seeking Trait, Pål Ø.U. Dåstol, Britt-Marie Drottz-Sjöberg

RISK: Health, Safety & Environment (1990-2002)

[Excerpt] "Risk judgments seem related to which definitions of risk a person uses. Earlier studies suggest that people who use a "probability" definition of risk give different, and somewhat lower, subjective estimates of risk than those who instead prefer a "consequence" definition. In addition, an "optimistic bias" often can be found, and subjects usually evaluate personal risk systematically lower than risk for people in general."
