The effect of perceptual interference on prioritization of feature dimensions in visual working memory

视觉工作记忆中回溯线索效应的影响因素 [The Influencing Factors of Retro-Cue Effect in Visual Working Memory]

The visual working memory is a temporary storage system, which encodes, maintains and retrieves visual information. The researchers have found that adding retro-cues to the maintenance phase of memory leads to changes in participants’ memory performance, which is the retro-cue effect. The magnitude of the retro-cue effect is not set in stone, but changes with the changes of its influencing factors. However, there is no study to summarize the influencing factors of the retro-clue effect. This paper looked into the articles related to the study of the retro-cue effect and summarized the influencing factors of the retro-cue effect: memory items, maintenance interval time, interference in maint…

不同情绪面孔的视觉工作记忆表现差异 [The Performance Difference of Visual Working Memory between Various Emotional Faces]

Among social-emotional stimuli, emotional faces occupy an important position, which specifically refer to human faces with certain facial expressions. The visual working memory is a limited workspace where information can be saved online and can be accessed and operated by advanced cognitive function during the maintenance period. A large number of behavioral and electrophysiological studies have shown that there are differences in visual working memory performance of different emotional faces. Specifically, angry faces can enhance the visual working memory performance; fearful faces may cause some damage to visual working memory; sad faces will impair face recognition encoding in visual wo…

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 …

Sustained attention required for effective dimension-based retro-cue benefit in visual working memory

In visual working memory (VWM) tasks, participants’ performances can be improved through the use of dimension-based retro-cues, which direct internal attention to prioritize a particular dimension (e.g., color or orientation) of VWM representations even after the stimuli disappear. This phenomenon is known as the dimension-based retro-cue benefit (RCB). The present study investigates whether sustained attention is required for the dimension-based RCB by inserting interference or interruption between the retro-cue and the test array to distract attention. We tested the effects of perceptual interference or cognitive interruption on dimension-based RCB when the interference (Experiments 1 and…

视觉工作记忆中数量和精度的权衡关系是否受个体自发控制

There is a negative correlation between the quality and quantity of memory representations in visual working memory, and this negative correlation is seen as a trade-off between quantity and quality. However, it is unclear whether this trade-off is entirely stimulus-driven or can be controlled voluntarily by individuals according to task demands, which has led to a debate on the mechanism of memory resource allocation. This paper systematically reviews the development of research on whether the trade-off between quantity and quality is subject to individual voluntary control, and point out this voluntary control is influenced by the exposure duration and working memory capacity, and some su…
