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.
