Is there a self-positivity bias for destination memory? Behavioral and ERP evidence

Despite extensive existing research concerning source memory (i.e., memory for what has been said, given, or done to us by whom) during social interaction, destination memory (i.e., memory for what we have said, given, or done to whom) remains to be explored. Furthermore, although destination memory is believed to involve a self-reference process, it remains unclear whether such a process is sufficient to trigger a self-positivity bias. To address these issues, we combined the destination memory paradigm with the social dilemma game to compare destination memory for cooperation and cheating. Both behavioral performance and the neural index of successful encoding, the Dm (difference due to memory) effect, were concerned. Behaviorally, destination memory for cooperative, cheating, and neutral behaviors decreased successively. For neural activities, the pre-400 ms Dm effects during 200-400 ms were non-significant under any condition. In the latency windows of 400-800 ms and 800-1000 ms, the post-400 ms Dm effects were reliably observed for both cooperative and cheating behaviors and were statistically comparable between the two behavior types, but the effect was not obtained for neutral behaviors. These data suggest a self-positivity bias in the behavioral performance but not in the encoding-related Dm effects of destination memory
