ABSTRACT Although the medial temporal lobe (MTL) is traditionally considered a region dedicated to long‐term memory, recent neuroimaging and intracranial recording evidence suggests that MTL also contributes certain aspects of visual short‐term memory (VSTM), such as quality or precision retained VSTM content. This study aims further investigate MTL's role in through application transcranial direct current stimulation (tDCS) functional magnetic resonance imaging (fMRI). Participants underwent 1.5 mA offline tDCS over bilateral lobes using left cathodal right anodal electrodes, administered for either 20 min (active) 0.5 within 20‐min window (sham), counterbalanced design. As electrical passes midbrain structures with this montage, prior behavioral modeling protocol can modulate functions. To confirm examine its impacts on VSTM, participants completed color recall task immediately following tDCS, while undergoing fMRI scan subsequent 7.5‐min resting‐state scan, during which they focused fixation cross. Behavioral results indicated decreased without significantly affecting overall success. Furthermore, psychophysiological interaction analysis revealed modulated hippocampal‐occipital connectivity task, despite no main effect BOLD activity. Notably, modulation was observed 15–20 post‐tDCS, magnitude correlating participants' changes across active control conditions. Combined, these findings suggest intrinsic between sensory areas, thereby precision.

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. 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. 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.

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. Notably, degree remains consistent across conditions, indicating utilize retro-cues enhance same extent. In condition, significant cost (RCC) was observed, selectively discarded uncued from invalid trials, response accuracy drops chance levels, supporting removal hypothesis. ERP results reveal allocation (N2pc) remain uniform mechanism responsible for formation appears involve an all-or-nothing process discarding rather than flexible strategy. provides insights into information-processing VWM, suggesting conclusions drawn tasks with can be integrated findings tasks. These also illuminate flexibility internal during contribute our understanding processes

We conducted an experience sampling study (eight two-hourly prompts daily) where participants repeatedly performed short 2-back Go/no-go tasks daily assessed negative positive affective states, unpleasantness of a recent event to capture reactivity. analyzed two overlapping samples: dataset (N = 161/158). Our results showed better working was decreased affect on average unpleasant for given individual. better-than-average interaction higher event-unpleasantness predicted levels (i.e., reactivity). These findings may challenge account being universally related adaptive regulation. Although unlikely boosts memory, future studies should establish direction causality.

Previous research has shown that working memory processes are affected by emotions. However, it is not clear if both components - maintenance and processing of information modulated emotion. Since emotion intimately related to attention, we focused on attentional in memory. In a previous study, using complex span task, showed emotionally negative reduced neutral The objective the present study was first replicate results our second investigate whether maintaining emotional would affect information. Experiment 1, young adults were asked remember series five letters each followed images, either or neutral, be categorized. 2, participants required memorize digits order focus maintenance, experiments tasks performed under continuous articulatory suppression. longer times observed for stimuli than ones, lower recall when processed. higher performance images ones maintained. Overall, show impacts This consistent with models suggesting an trade-off between processing.

The dynamic characteristics of facial expressions might affect time perception. Compared with static emotional faces, faces are more intense, have higher ecological validity, and contain series information, which may lead to overestimation. In the present study, we aimed at investigating how angry perception, as measured using event-related potentials (ERPs). Dynamic neutral different durations (400, 600, 800, 1000, 1200, 1400, 1600 ms) were presented in classical temporal bisection paradigm. Participants asked judge whether duration face was closer 400 or ms. behavioral results showed a significant overestimation effect for compared both terms proportion long Bisection Point.

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 work 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 at stage because presence 2). Finally, impairment condition abrupt appearance 3). Taken together, findings indicate that previously established for resisting using extended more stimuli, such as faces.
