Individual Differences In Decision-Making And Emotions: A Study Of Alexithymia Using The Columbia Card Task, Kaycee A. Stewart Ms. Jul 2023

Individual Differences In Decision-Making And Emotions: A Study Of Alexithymia Using The Columbia Card Task, Kaycee A. Stewart Ms.

Electronic Thesis and Dissertation Repository

Making effective decisions requires a balance between rational thinking and emotional processing. Optimal decision-making approaches involve carefully analyzing available information to make informed and advantageous choices. This study investigates how people’s ability to identify, process, and express emotions (alexithymia) relates to their decision-making in different emotional contexts. We used the Hot and Cold versions of the Columbia Card Task (CCT) to evaluate how participants make decisions. By analyzing their decisions as a function of their alexithymia levels and three manipulated game parameters (loss probability, loss amount, and gain amount), we discovered that people with higher levels of alexithymia had reduced …


Supporting Dynamic And Distributed Decision Making In Acute Care Environments: Insights From A Cognitive Ethnography, Anthony Naimi Mar 2018

Supporting Dynamic And Distributed Decision Making In Acute Care Environments: Insights From A Cognitive Ethnography, Anthony Naimi

Electronic Thesis and Dissertation Repository

The way that medical decisions are carried out in hospital environments has undergone radical changes in recent years, in part as a result of the changing landscape of care. To make decisions, physicians are expected to keep abreast of a growing and changing body of medical and patient knowledge, collaborate more with clinical colleagues, and utilize more technologies to inform care than ever before. This dissertation reports on a five month cognitive ethnography in an ICU in Ontario Canada, and utilizes distributed cognition to understand the challenges that physicians face in making decision in modern acute care environments. It also …


Mathematical Modeling Of Stress Management Via Decisional Control, Matthew J. Shanahan Dec 2015

Mathematical Modeling Of Stress Management Via Decisional Control, Matthew J. Shanahan

Electronic Thesis and Dissertation Repository

Engaging the environment through reason, humankind evaluates information, compares it to a standard of desirability, and selects the best option available. Stress is theorized to arise from the perception of survival-related demands on an organism. Cognitive efforts are no mere intellectual exercise when ontologically backed by survival-relevant reward or punishment. This dissertation examines the stressful impact, and countervailing peaceful impact, of environmental demands on cognitive efforts and of successful cognitive efforts on a person’s day-to-day environment, through mathematical modeling of ‘decisional control’. A modeling approach to clinical considerations is introduced in the first paper, “Clinical Mathematical Psychology”. A general exposition …
