AB  - Attention priority of reward history, also called value-driven attentional 
      capture (VDAC), is different from that of saliency or contingency. The magnitude 
      of VDAC was found to be correlated with working memory capacity, but how 
      cognitive control interacts with the attentional allocation of reward association 
      is not clear. Here, we examined whether the distraction by learned color-reward 
      association would change under different working memory load conditions. 
      Participants were first trained with color-reward associations by searching a 
      green/red circle with low/high reward. Then, during the test session, 
      participants needed to search a unique shape while a green/red shape was either 
      presented as a distractor or not shown at all. To manipulate the working memory 
      load in the test, a digital memory task was integrated with the visual search 
      task in half of the trials (memory load condition), but not in the other half 
      (no-load condition). Consistent results were found in two experiments that the 
      magnitude of attentional capture caused by low-value distractors was larger under 
      memory load condition than under no-load condition, while there was no enough 
      evidence supporting the influence of memory load on attentional capture by 
      high-value distractors. These results suggested that working memory load, which 
      occupied part of cognitive resources, reduced the priority of target information 
      and might also modulate the strength of reward association holding in working 
      memory. These findings extend the knowledge regarding the influence of working 
      memory load on attentional capture of reward and suggest that reward-induced 
      distraction is dynamic and could be modulated by cognitive control.
