Collaborative remembering and defference of cognitive perspectives

众所周知，两个脑袋胜过一个脑袋。实验一采用Meundell，Hitch，& Kirby（1992）的序贯设计，比较了合作回忆和个体回忆的差异。所有被试首先被要求独立回忆材料。然后，一些人被分配到两人一组，必须合作回忆材料。正如预期的那样，协作组比个人回忆得更多。然而，最有趣的结果是，合作组回忆少于名义组（简单地汇集个人），因此表现出合作抑制。这些结果与许多以前的发现一致（例如，在实验2中，比较了合作回忆和个体回忆是否具有相同或不同的认知视角。与实验1一样，无论人们对事件的看法是相同还是不同，都能产生合作抑制，这种合作抑制的产生除了部分线索和社会游荡的抑制作用外，还与合作群体回忆标准的变化有关。

It is well known that two heads are better than one. In the recent experimental psychology of memory, this phenomenon has been investigated under the name of the collaborative remembering.In Experiment 1, collaborative and individual recall were compared in the sequential design developed by Meundell, Hitch, & Kirby (1992). All the subjects were first asked to recall the materials on their own incidently. Some people were then assigned to pairs and had to recall the materials collaboratively. As expected, collaborative groups recalled more than individuals. However, the most interesting result was that collaborative group recalled less than nominal groups (simply pooled individuals), thus exhibiting collaborative inhibition. These results are consistent with many previous findings (e.g., Weldon & Bellinger, 1997).In Experiment 2, collaborative and individual recall were compared if the pair had the same or different cognitive perspectives. As in Experiment 1, collaborative inhibitions obtained irrespective of whether people share the same or different perspective on events.The explanation for such collaborative inhibitions are considered in terms of the shift in collaborative group's recall criteria, in addition to the inhibitory functioning by part-list cuing and social loafing.
