Cued Memory Collaboration: Effects of Friendship and Type of Retrieval Cue

The effects of friendship and collaboration on memory retrieval were investigated in two experiments. The net negative effect of collaboration in memory retrieval and the effect of friendship were studied within a cueing framework. The aim of the study was to investigate the reduced cue effectiveness hypothesis. In Experiment 1, dyadic retrieval was compared to that of a nominal group (a pooled score from two individuals working individually). The task was to encode and retrieve 90 words individually or dyadically. The retrieval phase was supported by cues produced by others or produced by the participants themselves (individually or dyadically). In Experiment 2, friends were compared to non-friends in a memory retrieval phase. All participants retrieved alone in Experiment 2. The results of Experiment 1 revealed that dyadic retrieval suffered compared to nominal group retrieval and that no such discrepancies were found for retrieval with cues produced by others. In Experiment 2, friends could help each o...
