Previous study have explored the influence of explicit emotion priming on computational estimation strategy execution, but the corresponding influence of implicit emotion priming still remains unknown. The present study aimed to solve this problem. Participants were asked to complete two-digit multiplication computational estimation task, under different implicit emotion priming conditions (gender judgment task). In the two-digit multiplication computational estimation task, the computational estimation question was presented in the middle of the screen, meanwhile, two alternative answers were presented side by side at the bottom of the screen, participants were required to select which answer is correct, by using the down-up strategy (e.g., doing 30 × 50 = 1500 for 34 × 46). Behavioral results showed that the response speed under implicit happy and fear (vs. neutral and angry) priming conditions was quicker, and the accuracy under different priming conditions showed no significant difference. The ERP results showed that the influence of implicit emotion priming on computational estimation strategy execution consisted of two phases: in the first phase, the N1 amplitudes elicited by completing the multiplication computational estimation task were smaller under implicit fear (vs. angry) priming condition; in the second phase, the corresponding P2 amplitudes under implicit happy (vs. fear) priming condition were smaller. The present study indicated that implicit happy and fear experience contributed to complete computational estimation tasks, suggesting that implicit negative emotional (e.g., fear) experience was not always detrimental to computational estimation strategy execution.

先前的研究已经探讨了外显情绪启动对计算估计策略执行的影响，但内隐情绪启动的相应影响仍然未知。本研究旨在解决这一问题。要求参与者在不同的内隐情绪启动条件下完成两位数乘法计算估计任务（性别判断任务）。在两位数乘法计算估计任务中，计算估计问题出现在屏幕中间，同时，两个备选答案并排出现在屏幕底部，要求参与者选择正确的答案，通过使用自下而上的策略（例如，对 34 × 46 做 30 × 50 = 1500）。行为结果表明，内隐快乐和恐惧（相对于中性和愤怒）启动条件下的响应速度更快，不同启动条件下的准确率无显着差异。ERP结果表明，内隐情绪启动对计算估计策略执行的影响包括两个阶段：第一阶段，在隐性恐惧（vs.愤怒）启动条件下，完成乘法计算估计任务引起的N1幅度较小；在第二阶段，内隐快乐（vs.恐惧）启动条件下相应的P2幅度较小。本研究表明，内隐的快乐和恐惧体验有助于完成计算估计任务，这表明内隐的负面情绪（例如，
