目的探讨声音片段诱导的不同情绪背景对来源记忆的影响。方法采用来源记忆测试的多键范式,采用3×4二因素被试内设计,对不同情绪背景下来源记忆的反应时和正确率进行测试,分析其差异。结果 3种情绪背景下,来源正确和来源错误的反应时和正确率与新刺激差异有统计学意义(P<0.01);正性和负性情绪背景下来源错误和来源正确的反应时和正确率差异有统计学意义(P<0.01);被试的反应时和正确率的情绪效应不显著(P>0.05)。结论声音片段诱导的不同情绪背景下来源记忆比项目记忆的认知操作更复杂,需时更长,而且在不能提取来源或对提取的来源不确定时,反应时会延长。
Objective To explore the influence of different emotional backgrounds induced by sound clips on source memory. Methods The multi-key paradigm of source memory test was used to test the response time and correct rate of source memory under different emotional backgrounds using 3 × 4 two-factor in-test design, and the differences were analyzed. Results There were significant differences in response time and correct rate between the correct source and the source of the new stimulus (P <0.01) under the three kinds of emotional contexts, the source errors in the positive and negative sentiment and the correct response time and correct source (P <0.01). There was no significant effect on the response time and correct rate (P> 0.05). CONCLUSIONS: Source memories in different emotional contexts induced by sound clips are more complicated and take longer to be learned than the memory of items, and the response time will be prolonged when the source can not be extracted or the source of extraction is uncertain.
