视觉工作记忆存储的表征单位 [The Representation Unit of Visual Working Memory]
2022
The visual working memory is a limited storage system in which people could flexibly process the representations to complete the task. Among studies on the capacity of visual working memory, the representation unit is a prior subject. Previous research employs the change-detection paradigm and the recall paradigm to explore the nature of representations when features of diverse dimensions and different-level features of the same dimension are stored in the visual working memory. These studies elicit two binary hypotheses: the object-based representation hypothesis backs that those diverse features are bound on the object and form a whole, while the feature-based representation hypothesis su…
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]
2022
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…
Electrophysiological evidence supports the role of sustained visuospatial attention in maintaining visual WM contents
2019
Recent empirical and theoretical work suggests that there is a close relationship between visual working memory (WM) and visuospatial attention. Here, we investigated whether visuospatial attention was involved in maintaining object representations in visual WM. To this end, the alpha lateralization and contralateral delay activity (CDA) were analyzed as neural markers for visuospatial attention and visual WM storage, respectively. In the single-task condition, participants performed a grating change-detection task. To probe the role of visuospatial attention in maintaining WM contents, two color squares were presented above and below the fixation point during the retention interval, which …
Attributes of democratic culture as represented in young children’s drawings
2022
Democratic culture refers to a set of values, attitudes, and practices shared by citizens and institutions, without which democracy cannot exist. Preschools and schools have a core role in teaching and transmitting democratic culture as they offer most children their early encounters with the public realm that provides social environments for democratic culture. The aim of this article is to increase knowledge on democratic education of young children and creative means to implement it. The core questions raised are: How do young children understand their classroom social environment and their own role in it? Which of the children’s understandings of their classroom social environment refle…
