The present study aimed to examine the attention residue of priming task and its influence with 2(priming vs.no priming) * 2(task complexity:high vs.low) between-subjects design.Participants were randomly assigned to conditions in which they were primed with sense of power or not.After the power priming procedure,participants were then assigned again to two similar tasks with high or low task complexity randomly,in which the high complexity group required participants to read about five resumes but the low group required participants to read about three resumes.Then all participants were asked to recall the key words on the resumes they’d read and write them down as many as they could.Results showed that the priming task performed by participants affects their performance in the following task as well as the priming effect.The study suggests that the attention residue of priming negatively impacts formal task performance and priming effect of participants,especially when the formal task has higher task complexity.This finding reveals a new perspective on the reasonable application of priming in experimental research.
