Abstract

Based on the Dual-Process Diffusion Model, we tested three hypotheses about response times of errors and correct responses in probability judgments. We predicted that correct responses were (1) slower than errors in the case of conflicting decision processes but (2) faster than errors in the case of alignment; and that they were (3) slower in the case of conflict than in the case of alignment. A binary-choice experiment was conducted in which three types of decision problems elicited conflict or alignment of a deliberative decision process and a heuristic decision process. Consistent with the traditional dual-process architecture, the former captured computational-normative decision strategies and the latter described intuitive-affective aspects of decision making. The hypotheses (1) and (3) were supported, while no statistically significant evidence was found for (2). Implications for the generalisability of the Dual-Process Diffusion Model to slow probability judgments are discussed.

摘要

基于双过程扩散模型，我们检验了关于错误响应时间和概率判断中正确响应的三个假设。我们预测正确的响应（1）在决策流程冲突时比错误要慢，但（2）在对齐方式时要比错误要快；并且（3）在冲突的情况下比在对齐的情况下要慢。进行了二元选择实验，其中三种类型的决策问题引发了协商决策过程和启发式决策过程的冲突或对齐。与传统的双流程体系结构一致，前者捕获了计算规范决策策略，而后者描述了决策的直观情感方面。支持假设（1）和（3），而没有发现（2）的具有统计学意义的证据。讨论了双过程扩散模型对慢速概率判断的可推广性。
