Selecting effectively contributes to the mnemonic benefits of self-generated cues

Self-generated memory cues support recall of target information more robustly than memory cues generated by others. Across two experiments, we tested whether the benefit of self-generated cues in part reflects a meta-mnemonic effect rather than a pure generation effect. In other words, can learners select better memory cues for themselves than others can? Participants generated as many possible memory cues for each to-be-remembered target as they could and then selected the cue they thought would be most effective. Self-selected memory cues elicited better cued recall than cues the generator did not select and cues selected by observers. Critically, this effect cannot be attributed to the process of generating a cue itself because all of the cues were self-generated. Further analysis indicated that differences in cue selection arise because generators and observers valued different cue characteristics; specifically, observers valued the commonality of the cue more than the generators, while generators valued the distinctiveness of a cue more than observers. Together, results suggest that self-generated cues are effective at supporting memory, in part, because learners select cues that are tailored to their specific memory needs.
