“…And these brain regions are closely related to the maintenance phase of visual working memory ( Kim, 2019 ; Sahu and Tseng, 2021 ). On the other hand, from the perspective of neuroplasticity, the synaptic connections between neurons are the basis of brain adaptation and learning, and it also plays an important role in the formation and maintenance of visual working memory ( Jeong et al, 2021 ; Yao et al, 2023 ). Whereas, insufficient sleep impairs synaptic connections between neurons, which affect the storage and maintenance of visual working memory ( Klinzing et al, 2019 ).…”

ObjectiveSleep quality can affect the performance of visual working memory. However, the effect of sleep quality on the maintenance stage, which is the key to maintain the quality and efficiency of visual working memory representation, remains unclear. This study is the first to explore the effect of sleep quality on the maintenance of visual working memory information.Method60 healthy college students completed the Pittsburgh Sleep Quality Index (PSQI) and color recall task of visual working memory. A mixed experimental design of sleep quality (high or low) and delay duration (1, 4, or 6 s) was used to assess the effect of sleep quality on the maintenance phase of visual working memory.ResultsThe main effects of sleep quality were significant on visual working memory quantity, precision and offset indexes. Among the quantity index, the interaction between sleep quality and delay duration was also significant. This suggests that prolonging the delay time in the maintenance phase leads to difficulty in maintaining attention to the task for those with lower sleep quality, which results in poorer working memory quantitative representations.ConclusionIncreases in the delay duration of the maintenance phase in visual working memory intensify the impact of sleep quality on task performance. Our study provides evidence to reveal the relationship between sleep quality and visual working memory and offers recommendations for improving sleep quality and cognitive functioning in individuals.
