本文提出了一个简单的形式化分析模型，提供定性预测的响应时间在二进制选择实验。它结合了双过程/多策略的方法与标准的扩散模型，建模的效用决策过程和启发式决策过程的证据积累的扩散过程。对于客观替代方案（包括判断和决策中的许多任务）的实验，该模型预测，在流程冲突的情况下，错误将比正确的响应更快，在对齐的情况下，错误将比正确的响应更慢，从而捕捉到有关缓慢或快速错误的有据可查的不对称性。此外，该模型还预测，在冲突的情况下，正确的反应比在对齐的情况下更慢，捕捉到了众所周知的Stroop效应。该模型还扩展到包括主观的替代评价，即优先选择的实验。在这种情况下，结果取决于试验是难还是容易，也就是说，取决于启发式是否可以被解释为相对自动的。版权所有（c）2016约翰威利父子有限公司
This paper presents a simple formal analytical model delivering qualitative predictions for response times in binary-choice experiments. It combines a dual-process/multi-strategy approach with the standard diffusion model, modeling a utility decision process and a heuristic decision process as diffusion processes of evidence accumulation. For experiments with objective alternatives (including many tasks in judgment and decision making), the model predicts that errors will be quicker than correct responses in case of process conflict and slower in case of alignment, capturing a well-documented asymmetry regarding slow or fast errors. Further, the model also predicts that correct responses are slower in case of conflict than in case of alignment, capturing the well-known Stroop effect. The model is also extended to cover experiments with subjective alternative evaluations, that is, preferential choice. In this case, results depend on whether trials are hard or easy, that is, on whether the heuristic can be interpreted as relatively automatic or not. Copyright (c) 2016 John Wiley & Sons, Ltd.
