Visual working memory (VWM) plays a crucial role in temporarily maintaining and manipulating visual information. Retro-cue benefit (RCB) refers to enhancement performance when attention is directed toward subset of items within VWM after their initial encoding. Our recent EEG studies have indicated that cue validity can influence the mechanisms underlying RCB formation, but previous research has not investigated whether differences exist formation between completely valid highly conditions. This study aims examine consistency retro-cues are (100% validity), compared with (80% validity).

In environments teeming with distractions, the ability to selectively focus on relevant information is crucial for advanced cognitive processing. Existing research using event-related potential (ERP) technology has shown active suppression of irrelevant stimuli during consolidation phase visual working memory (VWM). previous studies, participants have always been given sufficient time consolidate VWM, while suppressing distracting information. However, it remains unclear whether distractors requires continuous effort throughout their presence or this only necessary after task-relevant To address question, our study examines distractor in scenarios where limited. This investigates effect varying presentation durations filtering VWM. We tasked memorizing two color and ignoring four distractors, presented either 50 ms 200 ms. Using ERP technology, we discovered that distractor-induced positivity (PD) amplitude larger longer compared shorter ones. These findings underscore significant impact duration efficacy as prolonged exposure results a stronger distractors. sheds light temporal dynamics attention memory, emphasizing critical role stimulus timing tasks. provide valuable insights into mechanisms underlying VWM implications models memory.

Within the maintenance phase of visual working memory (VWM), previous researchers presented retro-cues orienting to a probed dimension across all multidimension stimuli and found robust dimension-based retro-cue benefit (RCB): VWM performance for cued was better than no/neutral-cue baseline. This improvement is often attributed prioritization information related focused removal unfocused from VWM. However, it remains unclear whether uncued necessary observe this RCB.

Abstract Visual working memory (VWM) is critical for temporarily storing and manipulating visual information but limited in capacity. Previous research suggests that perceptual organization, such as grouping identical objects, may alleviate VWM resource constraints, yet the underlying mechanisms remain unclear. This study investigated whether orientation stimuli reduce consumption this reduction occurs during encoding or maintenance phase. Using contralateral delay activity (CDA), an event-related potential (ERP) component indexes number of items stored VWM, we examined three conditions: all-same (i.e., four orientations), partial-same two pairs all-different different orientations) conditions. Behavioral results showed improved performance orientations increased, with highest condition. ERP revealed no significant differences early CDA amplitudes across conditions, suggesting do not However, late were significantly reduced condition compared to indicating benefits objects emerge Notably, partially did load, highlighting complexity integrating redundant information. These findings highlight distinct contributions consolidation phases optimizing through provide evidence facilitative effect relies on their complete repetition late-stage cognitive processes.

The relationship between sports expertise and working memory (WM) has garnered increasing attention in experimental research. However, no meta-analysis compared WM performance athletes non-athletes. This study addresses this gap by comparing these groups investigating potential moderators. A comprehensive literature search identified 21 studies involving 1455 participants from seven databases, including PubMed, Embase, ProQuest. Athletes primarily engaged basketball, football, fencing, while non-athletes included some as sedentary. risk of bias assessment indicated low across most domains. Publication bias, assessed through a funnel plot statistical tests, showed significant evidence bias. forest plot, using random effects model, revealed moderate heterogeneity. overall effect size statistically significant, albeit small, advantage for over (Hedges' g = 0.30), persisting types levels. Notably, was more pronounced when were contrasted with sedentary population 0.63), to the analysis where excluded non-athlete reference group 0.15). Our findings indicate consistent link improved performance, lifestyles appear be associated disadvantages.

Visual working memory (VWM) plays a crucial role in temporarily maintaining and manipulating visual information. Retro-cue benefit (RCB) refers to the enhancement of performance when attention is directed toward subset items VWM after their initial encoding. Our recent electroencephalogram (EEG) studies indicate that cue validity affects mechanisms underlying RCB formation. However, previous research has not thoroughly examined whether these differ between completely valid highly conditions. This study investigates consistency under conditions complete (100%) high (80%) retro-cue validity. We manipulated cognitive processing different using EEG. Specifically, we focused on N2pc component, which reflects attentional resource allocation, contralateral delay activity (CDA) quantity information retained VWM. The results, encompassing both behavioral event-related potential (ERP) findings, show participants 100% 80% exhibit robust RCB.

A fundamental question in memory research has long been the interplay between briefly maintaining information working (WM) and its enduring retention long-term (LTM). Much of explored how WM processes influence formation LTM and, turn, stored can either support or disrupt performance. This Special Issue Memory & Cognition brings together cutting-edge that delves into this relationship, showcasing studies reveal latest advances field. Additionally, it includes articles offering conceptual theoretical insights to better understand dynamic interaction LTM. The 25 presented here emphasize ways which is transferred from more durable representations LTM, as well flexibly draws on overcome limited capacity. In many ways, quality quantity contributions highlight importance jointly studying inspiring future work challenge pre-existing conceptions stimulate new directions field memory.
