摘要:
目的：考察不同难度任务的积极性反应策略调整是积极性调整还是由于任务需求。方法：采用停止信号范式，让被试在线索提示条件下对不同难度任务作反应。结果：信号相关与否线索条件下，相关条件下的无信号试次反应时和正确率都比无关条件下要高；不同信号比例线索条件下，高信号比例条件下的无信号试次反应时和正确率都比低信号比例条件下要高。但不管哪一种线索条件，高难度任务的反应时都比低难度要高，但正确率较低或没有差异。结论：被试在相同任务难度上一开始就采用积极调整的反应策略提高反应阈限，而不同任务难度的反应策略调整主要由于不同的任务需求。
Objective: Proactive response-strategy adjustments under different task difficulties are due to the proactive adjustment or task requirement. Methods: Participants act on different difficult tasks in Stop-signal paradigm according to clues. Results: Under the conditions of Stop signals relevant or irrelevant and different signal frequency, reaction times and correct rate of no-signal trial of Stop signals relevant are higher than those of irrelevant signal, reaction times and correct rate of no-signal trial of high signal frequency are higher than those of low signal frequency. Under the conditions of Stop signals relevant or irrelevant, reaction times of no-signal trial of high difficulty are higher than those of low difficulty, but the correct rates of no-signal trial of high difficulty are lower than those of low difficulty. Under the conditions of different frequency, reaction times of no-signal trial of high difficulty are higher than those of low difficulty, but the correct rates of no-signal trial of high difficulty are same with low difficulty. Conclusion: In the processing of response inhibition, participants may make proactive adjustment to enhance threshold of Response under same difficult tasks, and make adjustments due to task requirement under different difficult tasks.
