摘要:

个人、企业乃至国家在实际生活中需要做出涉及不同时间节点的决策, 此类决策在行为决策领域一般以“跨期偏好”作为衡量指标。而人类社会发展所必须做出的攸关生存发展的重要跨期决策实则是混合得失双结果的跨期决策。然而, 现有基于纯获得范式未能帮助我们理解和预测现实中更加复杂、真实的混合得失双结果跨期决策问题。为了描述并解释人们的混合得失双结果跨期偏好, 本项目拟: 1)通过不同逻辑合成混合得失双结果跨期决策的折扣率, 为模型比较提供尚缺乏的预测指标; 2)开发生态版的混合得失双结果跨期偏好任务, 为后续研究的开展提供更加生态化、有预测力的测量范式; 3)采用静态的直观模拟天平任务和动态的鼠标实验室、眼动追踪技术相结合的手段, 检验效用比较模型与属性比较模型何种可以更满意地解释混合得失双结果的跨期决策。

Abstract:

Individuals, enterprises, and countries need to make decisions involving different time nodes in real life. Such decisions are commonly measured by “intertemporal preference” in the field of behavioral decision-making. The most crucial kind of intertemporal decision making relevant to survival and development is the intertemporal choice with double-dated mix outcomes. However, existing intertemporal preferences measured by paradigms with pure gain outcomes were found to be poor predictors of far-sighted behavior in real life. To explore the characteristics of intertemporal choice with double-dated mixed outcomes, and investigate which theory could provide a satisfactory account for intertemporal choice with double-dated mixed outcomes, the present project tends to carry out three research. Study 1 is designed to synthesize indicators of intertemporal choice with double-dated mixed outcomes by using two different logics, providing predictive indicators for model comparison. Study 2 would develop a new ecological paradigm of measuring intertemporal choice with double-dated mixed outcomes, aiming to provide a more ecological and predictive measurement for the development of the following research. Study 3 aims to adopt the Mouselab and eye-tracking technique to test which model could more satisfactorily explain intertemporal choice with double-dated outcomes, the utility comparison model or the attribute-comparison model. Having sorted out the existing compensatory and non-compensatory models, and based on behavioral choice outcomes and behavioral process techniques, we proposed an explanation of integrative trade-off models. First, when people are faced with intertemporal choice with double-dated mixed outcomes, they would perform simplification of information within options with limited cognitive resources. Thus, we can determine whether decision-makers are more likely to use additive logic or integrated logic to simplify option information within options when processing. Second, based on the integration and simplification of within-option information, evidence based on the choice process helps reveal whether people apply the non-compensatory model to make an intertemporal choice with double-dated mixed outcomes. Finally, this project tends to improve predictive power for farsighted/short-sighted by introducing multiple time points, the combination of gain and loss outcomes into intertemporal choices. In summary, the current project proposes to combine evidence on choice outcomes and choice processes to test whether people make the intertemporal choice with double-dated mixed outcomes following utility or attribute comparison models/strategies, and to improve the predictive power of intertemporal preferences for realistic farsighted/short-sighted decisions. The implementation of the current project will help improve our understanding of the mechanisms of intertemporal preferences with double-dated mixed outcomes and provide a practical reference for people on which temporal strategies to choose in crises.
