Accurate assessment of risk propensity is important because risky choices underlie a broad range of behavioral problems. The Balloon Analogue Risk Task (BART) is an assessment that measures propensity to engage in risky choice. While this is a useful assessment, the BART changes two variables that affect risky choice simultaneously, probability of an undesirable outcome and stake size, which cannot be separated within the context of the BART. The goal of this study was to evaluate the separate and combined effects of key factors that are likely to risky choice (Magnitude of payoff, probability of an undesirable outcome, and stake size) in the context of a new analog to risky choice: The Wheel of Choice Task. Adults between the ages of 18 and 25 (N = 23) were recruited to participate in this study. On each trial, participants chose between spinning the wheel or collecting their earnings. Spinning could result in a payoff or a loss of earnings, and as such constituted a risky choice. Risky choices increased as the probability of bankruptcy decreased, as the magnitude of reinforcement for the risky choice increased, and as stake size decreased. Effects of all three independent variables were systematic and robust. In addition to the main effects, interaction effects were observed between probability of a bankruptcy and magnitude, magnitude and stake size, and between all three variables, indicating complex but systematic interplay between these powerful determinants of risky choice. Future directions for this line of research include a further parametric analysis of stake size as well as the Wheel of Choice task's utility as a clinical or experimental tool.
This volume is the result of a conference held at the University of California, Irvine, on the topics that provide its title -- choice, decision, and measurement. The conference was planned, and the volume prepared, in honor of Professor R. Duncan Luce on his 70th birthday. Following a short autobiographical statement by Luce, the volume is organized into four topics, to each of which Luce has made significant contributions. The book provides an overview of current issues in each area and presents some of the best recent theoretical and empirical work. Personal reflections on Luce and his work begin each section. These reflections were written by outstanding senior researchers: Peter Fishburn (Preference and Decision Making), Patrick Suppes (Measurement Theory and Axiomatic Systems), William J. McGill (Psychophysics and Reaction Time), and W.K. Estes (Choice, Identification and Categorization). The first section presents recent theoretical and empirical work on descriptive models of decision making, and theoretical results on general probabilistic models of choice and ranking. Luce's recent theoretical and empirical work on rank- and sign-dependent utility theory is important in many of these contributions. The second section presents results from psychophysics, probabilistic measurement, aggregation of expert opinion, and test theory. The third section presents various process oriented models, with supportive data, for tasks such as redundant signal detection, forced choice, and absolute identification. The final section contains theory and data on categorization and attention, and general theoretical results for developing and testing models in these domains.
"There are different views on what preferences for risks are and whether they are indicators of stable, underlying generic cognitive systems. Preferences could be conceived as an attitude towards a set of properties of context, memory and affect - a gauge of how much uncertainty one is willing to tolerate. This Research Topic aims to initiate a discussion on the stability of preferences for risks - as research has shown that different decision domains, response modes, and framing facilitate preference reversals. A consistent claim from behavioural decision researchers is that, contrary to the assumptions of classical economics, preferences are not stable and inherent constructs in individuals but are modified by levels of accessibility in memory, context, decision complexity, and type of psychological processing (e.g., sampling or computational "trade-offs" in processing). For example, in a sampling-based decision-making paradigm it is argued that preferences are not essential for making risky decisions. The existing theoretical and empirical evidence reveals that human preferences are relative and unstable, undermining the predictions of normative theory. Recent theoretical accounts in psychology have expanded the debate further by offering evolutionary models of decision-making under risk. While most of the researcher has explored optimisation goals (traditionally assumed in economics), evolutionary psychology has promoted adaptation-driven processes for risky choices. Moreover, we have witnessed a renaissance of preferences as affect rather than as a construct with psycho-economical properties. Although behavioural decision research is still engaged in challenging the foundation of economic theory, at present, opinions seem less unified as to whether preferences reflect common psychological constructs. The Research Topic will focus on human preferences and risky choices. Topics include: Normative, descriptive and experience-based decision making, Preference reversals, Accessibility in memory, Context dependence, Psychological processing (including i) probabilities, utilities, computations and 'trade-offs', and ii) sampling), Affect, and Evolutionary accounts." -- Provided by publisher.
This authoritative collection goes beyond economic statistics and probability data to offer a robust psychological understanding of risk perception and risk taking behavior. Expert contributors examine various risk domains in life, and pinpoint cognitive, emotional, and personality factors contributing to individual differences in risk taking as well as the many nuances social demographics (e.g., culture, gender) bring to risk decisions. Coverage takes competing theories and studies into account to identify mechanisms involved in processing and acting on uncertainty. And implications and applications are demonstrated in varied fields, from updated risk models for the insurance sector to improved risk communication in health services to considering risk perception in policy decisions. A sampling of the topics: Personality and risk: beyond daredevils—risk taking from a temperament perspective. Cognitive, developmental, and neurobiological aspects of risk judgments. The group effect: social influences on risk identification, analysis, and decision-making. Cognitive architectures as a scaffolding for risky choice models. Improving understanding of health-relevant numerical information. Risk culture as a framework for improving competence in risk management. Psychological Perspectives on Risk and Risk Analysis will be of great interest to researchers in and outside of psychology, including decision-making experts and behavioral economists. Additionally, this volume will appeal to practitioners who often have to make risky decisions, such as managers and physicians.
The majority of policymakers, academics, and members of the general public expected British citizens to vote to remain in the European Union in the 2016 referendum. This perception was based on the well-established idea that voters don't like change or uncertainty. So why did the British public vote to take such a major economic risk? Framing Risky Choices addresses this question by placing the Brexit vote in the bigger picture of EU and Scottish independence referendums. Drawing from extensive interviews and survey data, it asserts that the framing effect – mobilizing voters by encouraging them to think along particular lines – matters, but not every argument is equally effective. Simple, evocative, and emotionally compelling frames that offer negativity are especially effective in changing people's minds. In the Brexit case, the Leave side neutralized the economic risks of Brexit and proposed other risks relating to remaining in the EU, such as losing control of immigration policy and a lack of funding for the National Health Service. These concrete, impassioned arguments struck an immediate and familiar chord with voters. Most intriguingly, the Remain side was silent on these issues, without an emotional case to present. Framing Risky Choices presents a multi-method, comparative, state-of-the-art analysis of how the Brexit campaign contributed to the outcome. Uncovering the core mechanism behind post-truth politics, it shows that the strength of an argument is not its empirical validity but its public appeal.
Presents research utilizing laboratory experimental methods in economics.
This book presents new theory and empirical studies on the roles of cognitive workload and fatigue on repeated financial decisions. The mathematical models that are developed here utilize two cusp catastrophe functions for discontinuous changes in performance and integrate objective measures of workload, subjective experiences, and individual differences among the decision makers. Additional nonlinear dynamical processes are examined with regard to persistence and antipersistence in decisions, entropy, further explanations of overall performance, and the identification of risk-optimization profiles for long sequences of decisions.
