Understanding people's organ donation decisions may narrow the gap between organ supply and demand. In two studies, participants who had not recorded their posthumous organ donation decision (Study 1, N = 210; Study 2, N = 307) completed items assessing prototype/willingness model (PWM; attitude, subjective norm, donor prototype favorability and similarity, willingness) constructs. Attitude, su...

Recent literature on optimal investment has stressed the difference between the impact of risk and the impact of ambiguity also called Knightian uncertainty on investors’ decisions. In this paper, we show that a decision maker’s attitude towards ambiguity is similarly crucial for investment decisions. We capture the investor’s individual ambiguity attitude by applying α-MEU preferences to a sta...

Attitude diffusion is when “attitudes” (general, relatively enduring evaluative responses to a topic) spread through a population. Attitudes play an incredibly important role in human decision making and are a critical part of social psychology. However, existing models of diffusion do not account for key differentiating aspects of attitudes. We develop the “Multi-Agent, Multi-Attitude” (MAMA) ...

We propose a model of history-dependent risk attitude (HDRA), allowing the attitude of a decision-maker (DM) towards risk at each stage of a T -stage lottery to evolve as a function of his history of disappointments and elations in prior stages. We establish an equivalence between the existence of an HDRA representation and two documented cognitive biases. First, the DM’s risk attitudes are rei...

We find that Epstein (2010)’s Ellsberg-style thought experiments pose, contrary to his claims, no paradox or diffi culty for the smooth ambiguity model of decision making under uncertainty developed by Klibanoff, Marinacci and Mukerji (2005). Not only are the thought experiments naturally handled by the smooth ambiguity model, but our reanalysis shows that they highlight some of its strengths c...

In this research, the concepts of attitude and personality trait as well as their roles in agents’ decision-making concepts are discussed with regard to job selection and team member selection in multiagent team formation. This research introduces the concept of attitude to guide an agent’s behavior and personality trait to model other agents’ behavior tendency and identify helpfulness of them ...

The negative impact of Internet use on adolescents has received much popular attention and has also become a popular research topic. How to induce adolescent players to change their attitudes toward online gaming is one of the most important issues in online gaming addiction. The present study is based on the less-leads-to-more effect of dissonance theory. Experimental research was conducted to...

We applied the strength-energy model of self-control to understand the relationship between self-control and young athletes' behavioral responses to taking illegal performance-enhancing substances, or "doping." Measures of trait self-control, attitude and intention toward doping, intention toward, and adherence to, doping-avoidant behaviors, and the prevention of unintended doping behaviors wer...

Fishbein and Ajzerfs (1975) theory of reasoned action is currently the most successful and much discussed theory in attitude-behavior research. A l though the theory is well established for predicting behavior in various contexts, its central assumption of a static attitude-behavior intention relation appears questionable when recent results of cognitively oriented decision research are conside...
