Abstract：The attentional boost effect manifests itself as an increase in attentional resources for one task that improves performance on an unrelated but concurrent memory task. After the effect was introduced in 2010, researchers have conducted numerous studies on its occurrence characteristics and proposed a dual-task interaction model of the effect. In this paper, we focus on the research results in the past five years, and reformulate the mechanism of the attentional boost effect from different perspectives, as well as the new theoretical model: dual-task interaction model 2.0, in order to have a more comprehensive and in-depth understanding of the relationship between attention and memory under dual-tasking. At the same time, the neural basis, measurement indexes and theoretical models are proposed for further discussion.
