Why can’t we remember everything that experience? Previous work in the domain of object memory has suggested our ability to resolve interference between relevant and irrelevant features may limit how much can at any given moment. Here, developed an online mouse-tracking task study load influences reconstruction, testing participants synchronously over virtual conference calls. We first tested up 18 concurrently, replicating findings from a condition where were individually. Next, examined influenced mouse trajectories as reconstructed target objects. found contents working what was perceived during effect interacted with visual similarity load. Furthermore, previously studied but currently objects, providing evidence object-to-location binding errors. At greatest load, nearly three times more likely move their cursor non-target observed primarily reconstruction rather than period before final response. As dynamic interplay perception, these results show behavior be altered by: (i) is represented mind being viewed, (ii) information. Finally, discuss provide rich characterization participant millisecond temporal resolution, enormously increasing power cognitive psychology experiments.

To support goal-directed behavior, working memory (WM) must flexibly access relevant information. While the mechanisms underlying single-item WM are comparatively well-studied, less is known about principles governing multi-item access. Some studies have suggested that dual-item retrieval can be as efficient access, but it remains unclear whether this reflects reduced inhibitory demands or truly parallel, cost-free retrieval. In Experiment 1, we manipulated number of vs. irrelevant items in a pre-and retro-cuing task. The rationale was if benefit then having fewer to suppress would enhance performance. Instead, found selecting two out three slower and accurate than one, arguing against idea diminished inhibition underlies efficiency. Experiments 2a 2b further probed efficiency using modified dual-access paradigm leveraged object repetition benefits. By including control condition prevent temporal associations between repeated targets non-targets, observed benefits for each item were additive-consistent with serial limited parallel retrieval-rather overadditive, which expected under fully These findings clarify key limitations WM, important implications complex tasks such language comprehension, decision-making, problem solving.

Abstract Objective To investigate which brain activity frequency of electroencephalogram (EEG)-neurofeedback training (NFT) was the most effective for enhancing working memory (WM) and episodic (EM) in healthy participants through network meta-analysis (NMA). Methods Searched PubMed, Embase, Cochrane Library studies published from January 1990 to 2025. We performed Bayesian NMA, pooling continuous outcome data using standardized mean difference effect size (ES). Global local evaluations inconsistency were conducted chi-square test, side-splitting, loop-specific approaches. A consistency model applied global approach showed no significance. Efficacy ranks determined surface under cumulative ranking curve (SUCRA) each intervention. Publication bias assessed comparison-adjusted funnel plot Egger’s test. Finally, sensitivity analysis confirmed our findings’ robustness. Results Sixty included, comprising 50 trials on WM 24 EM. While significant (χ 2 (22) = 30.89, p 0.10) EM (10) 13.48, 0.19), exhibited between active control (AC) alpha combined with (WMT) (ES 6.64, < 0.001) WM, AC 0.84, 0.01) Alpha WMT (100%) NFT (87.0%) also highest efficacy according SUCRA. No publication found either type memory. The aligns original results. Conclusion Through (7–13 Hz) may be a crucial impacting Brain other methods requires more robust future investigation.

We explored how individual and age-related differences in working memory (WM) capacity affected subsequent long-term (LTM) retrieval. Unlike past studies, we tested WM LTM not only for items, but also item–color bindings. Our sample included 82 elementary school children 42 young adults. The participants performed a task with images of unique everyday items presented sequentially at varying set sizes different colors. Later, bindings from the task. load during encoding constrained LTM, higher retrieved more test. Even when accounting children’s poor item by considering that they did remember, exhibited an exacerbated difficulty remembering WM.

Abstract Proactive interference (PI) appears when familiar information interferes with newly acquired and is a major cause of forgetting in working memory. It has been proposed that encoding item–context associations might help mitigate familiarity-based PI. Here, we investigate whether encoding-related brain activation could predict subsequent level PI at retrieval using trial-specific parametric modulation. Participants were scanned event-related fMRI while performing 2-back memory task embedded 3-back lures designed to induce We found the ability control was modulated by left inferior frontal gyrus, hippocampus, bilateral caudate nucleus during encoding. These results provide insight processes underlying suggest temporal context details support control.

Both the experimental and psychometric investigation of WM capacity limit depend critically on assumption that performance in our tests reflects to a good approximation. Most tasks measure rely testing memory after short time during which participants are asked maintain information WM. In these tests, episodic long-term is likely also lay down trace set. Therefore, can draw two sources when tested, making it difficult separate contributions LTM immediate-memory tests.

Previous studies found that episodic long-term memory (eLTM) enhances working (WM) performance when both novel and previously learnt word pairs must be retained on a short-term basis.However, there is uncertainty regarding how WM draws eLTM.Three possibilities are (a) people draw eLTM only if capacity exceeded; (b) always contribution of to performance, irrespective whether prior knowledge helpful or not; (c) benefits specific comparisons between conditions which similarly ambiguous concerning LTM may useful.We built the assumption under from LTM, these traces memoranda could benefit hamper in tasks depending match stored ones to-be current trial, yielding proactive facilitation (PF) interference (PI), respectively.Across four experiments, we familiarized participants with some items before they completed separate task.In accordance possibility show indeed contributes performance.Performance deteriorated addition stimuli load was low, but not it high; an exchange information occurred exceeded, PI PF effects affecting immediate verbal visual at higher set sizes.
