内部注意在维度层面对视觉工作记忆的影响

Visual working memory is a memory system with limited capacity, thus internal attention plays a crucial role in selecting, controlling, and maintaining its stored content. Retro-cues are an important tool to study the influence of internal attention on visual working memory. Retro-cues are an important paradigm for studying the influence of internal attention on visual working memory. Depending on the different content of the cue, it can be divided into object-based retro-cue and dimension-based retro-cue and there are significant differences between them. The emergence of dimension-based retro-cue in recent years has become one of the hot topics of research. There are articles summarizing the research contents of object-based retro-cue, but the contents and progress of research on dimension-based retro-cue have not been sorted out and summarized. In this paper, we find that compared with object-based retro-cue, dimension-based retro-cue is more global, fragile; the effect of dimension-based retro-cue is influenced by visual dimensions, the number of memory sequences, individual differences and other factors; and the intrinsic mechanism of retro-cue benefits may be based on the reasons of preventing memory from time-based decay or taking non-target objects as the cost. Finally, we make suggestions for future directions and research.
