Abstract Capacity-limited visual working memory (VWM) requires that individuals have sufficient space and the ability to filter distractors. Negative emotional states are known impact VWM storage, yet their influence on distractor filtering within remains underexplored. We conducted direct neural measurement of participants (n = 56) who a lateralized change detection task with distractors, while manipulating state by presenting neutral or negative images before each trial. found detrimental effect distractors accuracy under both states. Using event-related potential (ERP) component, contralateral delay activity (CDA; sensitive load), observe load in condition, we state, showed significantly higher late CDA amplitudes when remembering 4 targets compared 2 but no significant difference In amplitude differences were evident targets, was targets. These results suggest maximum number items could store lower than Importantly, out not indicating impair VWM.

The differential impact of face distractors on visual working memory across encoding and delay stages

Attention Perception & Psychophysics, Год журнала: 2024, Номер 86(6), С. 2029 - 2041

External distractions often occur when information must be retained in visual working memory (VWM)-a crucial element cognitive processing and everyday activities. However, the distraction effects can differ if they during encoding rather than delay stages. Previous research on these used simple stimuli (e.g., color orientation) considering caused by real-world VWM. In present study, participants performed a facial VWM task under different conditions across stages to elucidate mechanisms of resistance context complex stimuli. performance was significantly impaired delay-stage but not encoding-stage distractors (Experiment 1). addition, effect arose primarily due absence distractor process at stage presence 2). Finally, impairment delay-distraction condition abrupt appearance 3). Taken together, findings indicate that previously established for resisting using extended more stimuli, such as faces.

The entorhinal-DG/CA3 pathway in the medial temporal lobe retains visual working memory of a simple surface feature

Classic models consider working memory (WM) and long-term as distinct mental faculties that are supported by different neural mechanisms. Yet, there significant parallels in the computation both types of require. For instance, representation precise item-specific requires separation overlapping representations similar information. This has been referred to pattern separation, which can be mediated entorhinal-DG/CA3 pathway medial temporal lobe (MTL) service episodic memory. However, although recent evidence suggested MTL is involved WM, extent supports WM remained elusive. Here, we combine an established orientation task with high-resolution fMRI test hypothesis retains visual a simple surface feature. Participants were retrospectively cued retain one two studied gratings during brief delay period then tried reproduce precisely possible. By modeling delay-period activity reconstruct retained content, found anterior-lateral entorhinal cortex (aLEC) hippocampal DG/CA3 subfield contain information associated subsequent recall fidelity. Together, these results highlight contribution circuitry representation.

Effortfulness of visual working memory: Gauged by physical exertion.

Journal of Experimental Psychology General, Год журнала: 2023, Номер 152(7), С. 2074 - 2093

Active maintenance of information in working memory (WM) is an essential but effortful cognitive process. Yet, the nature WM remains poorly understood. Here, we constructed a model to evaluate how perceived effort directly compared that physical exertion. In Experiment 1, participants freely chose either remember certain number colors visual task or hold hand dynamometer required percentage maximal voluntary contraction (%MVC) obtain fixed credit upon successful completion. We found discounted WM-related same way as they handgrip-related based on computation expected choice outcomes (hence utility) associated with different loads. This rationality observer's prospective 1 was generalized retrospective 2 where reported which more immediately after had performed both tasks randomized order without any reward feedback. 3 further probed this shared mechanism using dual-task paradigm. As predicted by our model, exertion could disrupt performance concurrent task, proportional iso-effort relationship between and when loads were high for tasks. Collectively, findings converge computational principle connecting load, effort, utility across domains. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The role of the parahippocampal cortex in memory consolidation for scenes

Classic models propose that forming lasting visual memories involves coordinated interactions between visually selective neocortical structures and the hippocampus during memory consolidation. However, precise role of in consolidation remains elusive, given their potential contributions spanning from initial perceptual encoding to subsequent reactivation. We capitalized on a unique opportunity, involving direct recording posterior parahippocampus its resection neurological patient, investigate impact scene-selective lesions First, with intracranial EEG, we confirmed functional relevance patient's resected tissues representing specific category, this case, scene images. Subsequently, identified disruption for scenes relative faces objects participant's postoperative visit. This finding prompted comprehensive analysis across different categories participant, as well an examination similar functions other patients intact parahippocampi cohort online participants. Through these within- between-participant comparisons, greater time-dependent reduction images following parahippocampus. Importantly, changes retention could not be attributed general lesions. Our findings, therefore, suggest reactivating areas is essential converting transient experiences into long-term memories.

All identical objects reduce memory load at the late maintenance stage in working memory

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Май 14, 2025

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.

Neural correlates of emotional working memory predict depression and anxiety

Frontiers in Neuroscience, Год журнала: 2025, Номер 19

Опубликована: Май 14, 2025

Introduction Emotional working memory (WM) plays a critical role in cognitive functions such as emotion regulation, decision-making, and learning. Understanding how emotional stimuli, particularly negative ones, affect WM performance is crucial for identifying markers of mental health issues like anxiety depression. Our objective to determine whether trait depression levels are associated with specific outcomes behavioral neural indicators demonstrate statistically significant correlations individual university students. Methods In our research: Experiment 1 ( n = 25) tested both positive stimuli under different loads (2 vs. 4 items), while 2 34) combined EEG recording investigate the index during WM. Results showed that impaired performance, especially higher loads, level being linked increased theta activity encoding decreased alpha retrieval. Additionally, individuals exhibited reduced sensitivity load differences tasks involving emotions. Discussion These results demonstrated patterns were significantly levels, suggesting potential utility measures at-risk student populations. By linking indicators, study contributes development personalized interventions monitoring treatment.
