Our new paper authored by Ziqing Yao, Xuanyi Lin and Dr. Xiaoqing Hu Optimistic amnesia: How online and offline processing shape belief updating and memory biases in immediate and long-term optimism biases just got accepted by Social cognitive and affective neuroscience!

Abstract: When people are confronted with feedback that counters their prior beliefs, they preferentially rely on desirable rather than undesirable feedback in belief updating, i.e., an optimism bias. In two pre-registered EEG studies employing an adverse life event probability estimation task, we investigated the neurocognitive processes that support the formation and the change of optimism biases in immediate and 24-hour delayed tests. We found that optimistic belief updating biases not only emerged immediately, but also became significantly larger after 24 hours, suggesting an active role of valence-dependent offline consolidation processes in the change of optimism biases. Participants also showed optimistic memory biases: they were less accurate in remembering undesirable than desirable feedback probabilities, with inferior memories of undesirable feedback associated with lower belief updating in the delayed test. Examining event related brain potentials (ERPs) revealed that desirability of feedback biased initial encoding: desirable feedback elicited larger P300s than undesirable feedback, with larger P300 amplitudes predicting both higher belief updating and memory accuracies. These results suggest that desirability of feedback could bias both online and offline memory-related processes such as encoding and consolidation, with both processes contributing to the formation and change of optimism biases.

The COVID-19 pandemic poses significant threat to humans’ physical and mental wellbeing. In response, there has been an urgent “call to action” for psychological interventions that enhance positive emotion and psychological resilience. Extending upon past research documenting the wellbeing benefits of generous action, we conducted two online pre-registered experiments (N =1,623) during the pandemic in which participants were randomly assigned to engage in other- or self-beneficial action. Specifically, participants made charitable donations or gained money for themselves (Experiment 1); purchased COVID-19-related or COVID-19-unrelated items for someone else or for themselves (Experiment 2). Results showed that prosocial behavior led to greater positive affect, meaningfulness, empathy and social connectedness. Affect benefits were detectable whether prosocial spending was COVID-19-related or not. These findings provide support for one strategy to bolster wellbeing during the pandemic – generous action – which may also promote cooperation and social cohesiveness needed to contain and overcome the virus.
