Summary: This study aimed to extend and replicate previous findings on the effects of memory load and duration on color representations in visual working memory. The results showed that visual working memory exhibits a stronger categorical bias for longer memory durations and intermediate memory loads.

Summary: The study found distinct neural substrates for phonological and orthographic working memory, with regions in the angular gyrus supporting orthographic working memory and regions primarily in the supramarginal gyrus supporting phonological working memory. This refutes the idea of a domain-general attentional mechanism in the parietal lobe and supports a domain-specific buffer account of working memory.

Summary: This response challenges Xu's claim about the non-essential role of the visual cortex in visual working memory, emphasizing the critical role of visual regions in WM. It argues for a distributed systems view of WM storage, highlighting how representations stored in various brain regions complement and interact with each other to contribute to behavior.

Summary: The action perspective on working memory suggests that memory representations are coded according to their specific temporal and behavioral task demands. In two experiments, we tested whether visual items that are memorized for different tasks are stored separately from one another or show evidence of inter-item interference during concurrent maintenance, indicating a common storage. Our results present evidence that items that are stored for distinct tasks to be performed at distinct points in time, reside in a common workspace in working memory.

Summary: Visual working memory can maintain both continuous-perceptual information and discrete-categorical information about memory items. The representation structure in working memory differs for different features, with a joint-representation structure for orientation and separate-representations structure for color and shape. Existing models fail to capture this distinction, leading to mischaracterization of memory precision.

Summary: The study found that individuals with aphantasia, who cannot experience visual imagery, show no impairment in visual working memory tasks. While they differ in the strategies used, they perform similarly to controls in terms of capacity limits and visual memory accuracy.

Summary: Previous studies have shown that high-level cognitive functions such as attention can modulate the tilt aftereffect (TAE), but it is unclear whether working memory load has an effect on TAE. Two experiments were conducted, with one showing a reduction in TAE magnitude under high working memory load when digits were used as load stimuli, while the other experiment did not replicate this finding when color-shape conjunctions were used as load stimuli. Further replications are needed to clarify the effects of working memory load on TAE.

Summary: This paper proposes a Dual-Attention Network (DANet) for robust video representation in view-invariant action recognition. The DANet consists of relation-aware spatiotemporal self-attention and spatiotemporal cross-attention modules, which capture dependencies and generate discriminative features for semantic representations of actions in different views. Experimental results demonstrate that the proposed approach significantly outperforms state-of-the-art approaches in view-invariant action recognition.

Summary: This study found that there are connectivity deficits in the working memory network in first-episode schizophrenia patients. The ability to enhance communication between perceptual and executive networks in response to increasing cognitive demands is impaired in these patients, and the degree of impairment is associated with positive symptoms.

Summary: In this study, the change detection paradigm was used to investigate the working memory of patterned movements and its relationship with the visuospatial sketchpad. The experiments revealed that individuals can store 3-4 patterned movements in working memory, but changes in stimulus type and memory load can affect the processing efficiency. The results also showed that working memory and visual working memory are independent when processing patterned movements, but the working memory of patterned movements is influenced by spatial working memory.

Summary: Prospective action plans are brought into working memory early, in tandem with sensory encoding, and precede a second stage of action preparation based on the time of expected memory utilization. This dual visual-motor memory code can make memories more effective and robust in serving ensuing behavior.

Summary: The study showed that visual representations in working memory are influenced by the categorical structure of the stimulus space. Analysis of EEG data revealed that biases in working memory representations exist prior to the report, rather than arising during decision or response processes. Follow-up experiments further confirmed these findings.

Summary: This paper studies the cross-view geo-localization problem and proposes a framework called RK-Net to jointly learn discriminative representation and detect salient keypoints using the USAM module. The integration of USAM enables end-to-end joint learning, simplifies implementation, and enhances overall performance, achieving competitive accuracy on challenging datasets.

Summary: We conducted a study to investigate transsaccadic working memory (tWM). Our findings revealed that tWM involves at least two components, reflecting working memory capacity and strategic aspects of working memory, respectively. We also found that the left visual field showed reduced capacity compared to the right visual field, and remapping difficulties between visual fields were observed. Additionally, rightward saccades were found to have a greater impact on working memory, possibly due to interference from attention shifts.

Summary: This paper proposes a method to create view-invariant action descriptions using skeletal self-similarities and learning with a multi-stream neural network. By integrating skeletal self-similarities of different scales into the network, the method shows good robustness to view changes.
