A Dual-process Model of Framing Effects in Risky Choice
نویسندگان
چکیده
This work investigates the intuitive and deliberative cognitive processes underlying risky decision-making by manipulating time pressure. A recent fMRI study by De Martino et al. (2006) found greater activation of the amygdala when exhibiting framing effects suggesting that they may be driven by System 1. Because this system is characterized as being fast, we expect more pronounced framing effects under time pressure. In our experiment, we manipulated time pressure and accuracy and use a dynamic dual-process model to explain our results. The model we develop is a sequential sampling model in which the drift rates and boundaries vary in accordance with the thinking modes, frames, and time pressure.

Cardioception and framing effects
Previous studies suggest in line with dual process models that interoceptive skills affect controlled decisions via automatic or implicit processing. The " framing effect " is considered to capture implicit effects of task-irrelevant emotional stimuli on decision-making. We hypothesized that cardiac awareness, as a measure of interoceptive skills, is positively associated with susceptibility to...
متن کاملThinking Fast Increases Framing Effects in Risky Decision Making.
Every day, people face snap decisions when time is a limiting factor. In addition, the way a problem is presented can influence people's choices, which creates what are known as framing effects. In this research, we explored how time pressure interacts with framing effects in risky decision making. Specifically, does time pressure strengthen or weaken framing effects? On one hand, research has ...
متن کاملMemory reflected in our decisions: Higher working memory capacity predicts greater bias in risky choice
The current study looks at the role working memory plays in risky-choice framing. Eighty-six participants took the Automatic OSPAN, a measurement of working memory; this was followed by a risky-choice framing task. Participants with high working memory capacities demonstrated well pronounced framing effects, while those with low working memory capacities did not. This pattern suggests that, in ...
متن کاملFraming effects and risk-sensitive decision making.
Prospect theory suggests that people are risk-averse when facing gains, but risk-prone when facing losses, a pattern known as the framing effect. Although framing effects have been widely demonstrated, few studies have investigated framing effects under conditions of need. Risk-sensitivity theory predicts that decision makers should prefer high-risk options in situations of high need, when lowe...
متن کاملA New Look at Framing Effects:
Levin, Schneider and Gaeth (1998) identified three distinct types of framing effects in the literature: attribute-framing effects, goal-framing effects, risky choice-framing effects. While most previous framing studies used between-subjects manipulations of frame, the present study used two sessions, spaced one week apart, to give each of 102 participants both framing conditions and all three t...
