摘　　要：目的:通过操作项目竞争强度来探讨焦虑特质大学生提取诱发遗忘(RIF)是否受相关代价与效益问题(CCB)的影响。方法:从618名大学生中筛选出高焦虑特质组[特质焦虑量表(T-AI)总分≥53分]和低焦虑特质组(T-AI总分≤33分)各24人,采用2 (焦虑特质类型:高、低)×2 (项目竞争强度:高、低)×4 [项目类型:练习项目(Rp+)、未练习项目(Rp-)、基线项目+(Nrp+)、基线项目-(Nrp-)]混合设计,通过提取练习范式考察两组被试在不同项目竞争强度下的RIF和CCB。结果:在高项目竞争强度下,高、低焦虑特质大学生Rp-的正确回忆率均低于Nrp-[(61.8±18.7)%vs.(72.9±18.9)%,(57.6±19.0)%vs.(70.8±17.9)%;均P <0.05];在低项目竞争强度下,两类被试在Rp-和Nrp-上的正确回忆率差异均无统计学意义(均P> 0.05)。结论:焦虑特质大学生记忆提取中的抑制控制加工未受损,其在高项目竞争强度下产生的是抑制性提取诱发遗忘,且未受到相关代价与效益问题的影响。Objective: To explore whether retrieval-induced forgetting(RIF) in college students with anxiety trait are affected by the correlated costs and benefits problem(CCB) by manipulating item competitive intensity.Methods: The Trait Anxiety Scale(T-AI) was used to screen 24 participants with high-level of anxiety trait(T-AI total score of ≥ 53) and another 24 participants with low-level of anxiety trait(T-AI score of ≤33) from618 college students.The 2(anxiety trait type: high,low)× 2(item competitive intensity: high,low)× 3(item type: Rp+,Rp-,Nrp+,Nrp-) mixed design was performed to investigate both RIF and CCB of the two groups under different item competitive intensity by retrieval-practice paradigm.Results: Under the condition of high-item competitive intensity,the rate of correctly recalled Rp-items for college students with high-level [(61.8± 18.7)% vs.(72.9 ± 18.9)%,P < 0.05] and low-level [(57.6 ± 19.0)% vs.(70.8 ± 17.9)%,P <0.05]of anxiety trait was lower than that of Nrp-items,but there was no significant difference between them in the condition of low-item competitive intensity(Ps > 0.05).Conclusion: The inhibition control processes in memory retrieval for college students with anxiety trait is not impaired,and the inhibition-based RIF produced under the condition of high-item competitive intensity is not affected by CCB.
