ERP Studies Of The Domain-specific Risk-taking

The researchers have been arguing about when participate in the different fields risktaking behavior are shown consistent or inconsistent risk propensity? And a particular personality will affect individuals risktaking behavior in various fields showed a consistent risktaking? These problems are still the focus of debates (Morrongiello, Lessard,& Corbett,2009). Weber et al. (2002) developed The Domain-specific Risk-taking questionnaire, put forward the "domain specific" concepts and propositions clearly. She emphasized, the individual risk in one field, in other fields may not risk, risktaking behavior is according to the different feilds have different activities. Domain specific risktaking behavior based on the high risk individual’s performance in different areas, and Crowley et al. (2009) research on the high, low risk individuals in economic decision-making characteristics of cognitive processing, this research adopts Domain-specific Risk-taking questionnaire, selected high risk individuals in the field of economic, social/moral, and entertainment/health and safety. Comparison cognitive processing characteristics when the 3 areas typical individuals participating in the economic decision-making tasks. Using a simple gambling task about economics to explore the cognitive and neural mechanism of decision making process through, when the high risk individuals of the different domains participates in the task about the economy.In this study, using the domain-specific risk-taking questionnaire and selected 54 people (Each group:n=18) join the ERPs experiment, the participants completed a simple gambling task, through describe the different stimuli (gain, loss) to compare the neurophysiological characteristics of the risky behavior. Through analysis the data, the current study reached following conclusions:(1) In the behavior results, the economic group choice more risktaking options than social group and entertainment group, illustrated economic group more risks than social morality and entertainment group.(2) The economic group participated in economic decision-making task’s EEG amplitudes were greater than the other two groups, it’s showed that ristaking behavior have the domain-specific characteristics.
