摘　　要：通过考察特质反刍思维大学生在强、弱项目竞争强度下的提取诱发遗忘(retrieval induced forgetting,RIF),以厘清其记忆抑制的特点及RIF形成机制。调查1 828名大学生,从反刍思维量表得分前后27%的被试中,分别随机选取32人作为高、低特质反刍思维组,采用提取练习范式考察两组被试的RIF。结果发现:高特质反刍思维组在弱项目竞争强度下未练习项目(Rp-)的回忆正确率低于基线项目(Nrp-)(t(31)=-2.38,P<0.05),在强项目竞争强度下Rp-与Nrp-的回忆正确率差异不显著(P>0.05);低特质反刍思维组在强项目竞争强度下Rp-的回忆正确率显著低于Nrp-(t(31)=-2.82,P<0.01),在弱项目竞争强度下Rp-与Nrp-的回忆正确率无显著差异(P>0.05)。说明高特质反刍思维大学生的记忆抑制受损,在弱项目竞争强度下易受相关代价与效益问题影响而产生干扰性RIF,进而混淆对RIF形成机制的解释。To understand the feature of memory inhibition and the mechanism of retrieval-induced forgetting(RIF)in undergraduate students with trait rumination,we examined the impact of item competition intensity on their RIF.1828 undergraduate students were surveyed by using the Rumination Response Scale(RRS)and 32 individuals were selected randomly from top and bottom 27%subjects of the score of the RRS,respectively,as the high levels and low levels of trait rumination,and then the retrieval practice paradigm was used to examine the RIF of the two groups.The results showed that in the high trait rumination group,the percent of correct recall for Rp-items was lower than that for Nrp-items under the weak level of item competition intensity(t(31)=-2.38,P<0.05),and there was no statistical significance in the percent of correct recall for Rp-and Nrp-items under the strong level of item competition intensity(P>0.05).However,in the low trait rumination group,the percent of correct recall for Rp-items was lower than that for Nrp-items under the strong level of item competition intensity(t(31)=-2.82,P<0.01),and there was no statistical significance in the percent of correct recall for Rp-and Rp-items under the weak level of item competition intensity(P>0.05).The research revealed that undergraduate students with high trait rumination impaired memory inhibition,and they were so easily affected by the correlated costs and benefits problem(CCB)under the weak level of item competition intensity which resulted in interference-based RIF,thus confusing the mechanism of RIF.
