title: Can concurrent memory load reduce distraction? A replication study and beyond.
abstract: The effects of concurrent working memory load in attentional processes have been 1 of the most puzzling issues in cognitive psychology. Studies have shown detrimental effects, no effects, and even beneficial effects of working memory load in different attentional tasks. In the present study we attempted to replicate Kim, Kim, and Chun's (2005, Experiment 3b) findings of beneficial effects of concurrent working memory load in a spatial Stroop-like task. In 3 experiments in which our sample was 3 times larger than that in the original Kim et al. study, we could not replicate their findings. The results are discussed in terms of what may have produced the conflicting results, trying to shed light on how working memory load affects attentional tasks. Also, we emphasize the importance of using adequately large samples in cognitive research. Although we acknowledge the relevance of meta-analyses to analyze conflicting results, in the present article we stress (perhaps more important) the power of an essential trademark in science for research development: replicability.
