Responses to risky choices were collected and analyzed in a continuous, engaging and decomposable risk taking task; a slightly modified version of BART (Balloon Analog Risk Task [1]). Pupil dilation data throughout the experiment were collected and analyzed to understand participants' physiological expressions under risky choices. Participants were also administered a survey, prior to the experiment to monitor individual risk taking attitudes. A thorough analysis of responses indicated a dynamic system consisting of risk taking or aversive states. Participants' pupil dilation rates were predictable from this dynamical model abstracted from consecutive responses. These findings may lead to a model that fuses affective and cognitive aspects within risky uncertain decisions. Natural risk tendencies, extracted from the survey had no statistically significant effect on the results.

A risk management approach for acquisition of software intensive systems in the Turkish Army.
Saylan, Necip; Demirös, Elif; Demirös, Onur; Department of Information Systems (2002)
The current techniques of risk assessment rely on checklists and human expertise. This constitutes a rigorous approach only when the people are experts on risk assessment. This thesis introduces a formal method and addresses the necessity of the identification and analysis of the risk. During implementation of risk management process, risk assessment will be discussed within an acquisition of software intensive systems in the Turkish Army. This thesis includes a survey and comparison of other software risk ...
An Experimental Study on Impact of Risk Data Visualization onRisk Evaluations
Dikmen Toker, İrem; Eken, Görkem (null; 2018-11-18)
Risk assessment is a systematic process to characterize and evaluate risk, with the available knowledge. Thus, its success depends significantly on the "availability of knowledge" during the assessment process. The knowledge elicitation from experts, the structure of the risk database and information visualization that may help sense-making from previous projects are critical factors that can improve risk assessment process. Risk assessment is usually carried out at the start of a project and updated during...
Application of a risk visualization framework using semantic risk data to empower risk communication
Ertaymaz, Muzaffer Uğurcan; Atasoy Özcan, Güzide; Department of Civil Engineering (2020)
Risk communication is one of the major factors that effects the success of a project. Conventional risk management focuses on risk checklists and matrices, and considerable amount of risk information is discarded and not communicated. Without communicating the necessary risk information, risk management strategies cannot be applied effectively. The purpose of this study is to develop a systematic and practical risk visualization framework that shall improve the risk communication strategies. The proposed fr...
The Impact of the Level of Fear Experienced During the COVID-19 Epidemic on Risk Aversion and Work Interaction Avoidance Behaviors: An Application on Health Professionals
Yalman, Fuat; Sancar, Tekin (ODTÜ- AYNA Klinik Psikoloji Destek Ünitesi, 2022-2)
The main purpose of this study was to determine the effect of the level of fear experienced during the COVID-19 epidemic on risk aversion and work interaction avoidance behaviors. Healthcare workers have always been the group with the highest risk of contracting virus, as they put their lives at risk in all pandemics to fight epidemics on the front lines. Hospital-based cross-sectional research design was used in the study. The universe of the research consisted of all healthcare professionals of two differ...
Measuring risk tolerance in finance: Does the decision frame matter?
Özdemir, Özlem (2013-06-01)
Risk taking behavior has great influence on the decision making process of individuals. In this respect, the methodology used in assessing individuals’ risk tolerance becomes an important issue. However, there is lack of unique and commonly used risk tolerance measure in literature. There are mainly two different approaches in measuring risk tolerance in literature; lottery versus financial risk assessment technique (FRT). The purpose of this study is to investigate whether measurement techniques differ wi...
