Abstract

The present study investigated whether the magnitude of self-reference effects would differ for positive versus negative information as a function of self-positivity bias within a source monitoring paradigm. In Experiment 1 where a memory test immediately followed a learning phase, the size of self-reference effects was significantly larger for the positive words compared to negative words. This decrease in the magnitude of self-reference effects for negative words was found to be more pronounced in Experiment 2 where a 24-hour interval was introduced between learning and memory test phases: no self-reference effect for negative words. The present findings suggest that due to the self-positivity bias, the association between a memory and its source become systematically biased toward positivity when a memory is self-relevant as well as toward negativity when a memory is about others. Overall, the current findings provide support for the crucial role of memory in maintaining and enhancing positive self-image and further suggest that memory bias, which has mostly been discussed for its negative consequences, may serve a functionally adaptive role by enhancing individuals' positive self perception and subjective well-being.
