协作抑制是指当人们在一个记忆小组中一起提取信息的时候,小组提取的信息总量比等量个体提取的信息总量要少。本研究采用经典的协作抑制研究范式和两次提取任务,考察编码方式和学习次数对协作提取任务的影响,从而进一步探讨协作抑制的产生机制。结果表明,编码方式相同条件下出现协作抑制,而编码方式不同条件下协作抑制消失,显示协作抑制的出现与否依赖于认知条件的改变;无论是学习一次还是学习两次,在第一次小组提取中出现协作抑制,而在第二次个人提取中协作抑制消失,在使用困难学习材料时也得到同样的研究结果。研究结果支持协作抑制的提取策略破坏假说。
Collaborative inhibition means that when people extract information together in a memory group, the total amount of information extracted by the group is less than the total amount of information extracted by equal individuals. In this study, the classical collaborative inhibition research paradigm and two extraction tasks were used to investigate the influence of encoding methods and learning times on collaborative extraction tasks, so as to further explore the mechanism of collaboration inhibition. The results showed that under the same coding conditions, cooperative inhibition occurred, while the cooperative inhibition disappeared under different coding conditions, indicating that the occurrence of cooperative inhibition depends on cognitive conditions; whether learning or learning twice, in the first Collaboration inhibition occurred in the panel extraction, but disappeared in the second individual extraction, and the same results were obtained when using difficult learning materials. The results support the disruption hypothesis of collaborative inhibition extraction strategy.
