Positive mood is associated with the implicit use of distraction.

Previous research demonstrates that individuals in a positive mood are differentially distracted by irrelevant information during an ongoing task (Rowe et al. in Proc Natl Acad Sci 104:383-388, 2007). The present study investigated whether susceptibility to distraction shown by individuals in a positive mood results in greater implicit memory for that distraction. Participants performed a similarity-judgment task on pictures that were superimposed with distracting words. When these previously distracting words could be used as solutions on a delayed implicit task administered several minutes later, performance was positively correlated with pleasantness of mood. Individuals in a positive mood are more likely than others to use previously irrelevant information to facilitate performance on a subsequent implicit task, a finding with implications for the relationship between positive mood and creativity.
