Visual working memory (VWM) relies on a distributed cortical network. Yet, the extent to which individual areas, like early visual cortex and intraparietal sulcus, are essential VWM storage remains debated. Here, we reanalyze key datasets from two independent labs address three topics at forefront of current-day research: Resiliency mnemonic representations against distraction, role attentional priority in memory, brain–behavior relationships. By utilizing different analysis approaches, each...
Visual working memory (VWM) is used to retain relevant information for imminent goal-directed behavior. In the experiments reported here, we found that VWM helps prioritize not yet available conscious experience. five experiments, demonstrated matching content reaches visual awareness faster than does content. Our findings suggest a functional link between and awareness: The of recruited funnel down vast amount sensory input which subsequent behavior therefore requires access.
Visual working memory (VWM) is used to maintain visual information available for subsequent goal-directed behavior. The content of VWM has been shown affect the behavioral response concurrent input, suggesting that representations originating from and sensory input draw upon a shared neural substrate (i.e., <i>sensory recruitment</i> stance on storage). Here, we hypothesized maintained in would enhance matches VWM. To test this hypothesis, measured fMRI BOLD responses task-irrelevant stimuli...
A large part of research on visual working memory (VWM) has traditionally focused estimating its maximum capacity. Yet, humans rarely need to load up their VWM maximally during natural behavior, since information often remains accessible in the external world. Recent work, using paradigms that take into account accessibility outside world, indeed shown observers utilize only one or two items before sampling from world again. One straightforward interpretation this finding is that, daily much...
A recent focus in the field of consciousness research involves investigating propensity initially non-conscious visual information to gain access consciousness. critical tool for measuring conscious is so-called breaking continuous flash suppression paradigm (b-CFS). In this paradigm, a high contrast dynamic pattern presented one eye, thereby temporarily suppressing target stimulus that other eye. The time it takes observers report (e.g., location of) suppressed provides measure access....
Visual working memory (VWM) is a capacity-limited cognitive system that utilized for enabling goal-directed actions. When sampling items VWM storage, however, observers are often exposed to other not selected imminent action (hereafter: "prospective items"). Here, we asked whether such exposure leads buildup of these prospective items, facilitating subsequent encoding action. In series experiments, addressed this question using copying task, in which participants attempted reproduce model...
Predicting the location of moving objects in noisy environments is essential to everyday behavior, like when participating traffic. Although many provide multisensory information, it remains unknown how humans use information localize objects, and this depends on expected sensory interference (e.g., occlusion). In four experiments, we systematically investigated localization for auditory, visual, audiovisual targets (AV). Performance was compared performance predicted by maximum likelihood...
As we navigate our visual environment, viewpoint shifts, causing predictable changes in objectappearance. Moving forward, for instance, increases the retinal size of objects a scene,proportionally with distance travelled. Such regularities can be exploited to predict objecttransformations, thereby facilitating object perception. Previous research showed that observersautomatically orientation an from rotation surrounding scene. Itremains unknown, however, whether this is ubiquitous property...
In everyday vision, objects in scenes are often poorly or only partially visible, for example because they occluded appear the periphery. Previous studies have shown that visual system can reconstruct missing object information based on spatial context static displays. Real-world vision is dynamic, however, causing appearance of (e.g., their size and viewpoint) to change as we move. Importantly, these changes highly predictable from 3D structure surrounding scene, raising possibility cortex...
Working memory (WM) enables temporary retention of task-relevant information for imminent use. Increases in visual WM load are accompanied by elevated contralateral delay activity (CDA), and EEG alpha-band power. While most research focuses on the domain, it remains unknown whether similar responses also reflect auditory domain. Using EEG, we set out to establish such neuro-markers load. Participants memorized pitches 1 4 pure tones presented one ear, with consistent distractor other ear....
<title>Abstract</title> Humans and many other animals possess an innate ability to rapidly perceive numerosity: the number of objects in a visual scene. Numerosity perception is influenced by adaptation, whereby previously viewed numerosities affect current image’s numerosity. Parietal frontal neural populations are tuned specific preferred numerosities, this tuning affected adaptation. A parallel line research has revealed that early responses monotonically increase with Here we use...
Abstract The way humans perceive the outcomes of their actions is strongly colored by expectations. These expectations can develop over different timescales and are not always complementary. present work examines how long-term (structural) – developed a lifetime - short-term (contextual) jointly affect perception. In two studies, including pre-registered replication, participants initiated movement an ambiguously rotating sphere operating rotary switch. absence any learning, predominantly...
Abstract Our visual environment is relatively stable over time. An optimized system could capitalize on this by devoting less representational resources to objects that are physically present. The vividness of subjective experience, however, suggests externally available (perceived) information more strongly represented in neural signals than memorized information. To distinguish between these opposing predictions, we use EEG multivariate pattern analysis quantify the strength task-relevant...
Steady-State Visual Evoked Potentials (SSVEPs) provide a report-free and continuous measure of neural processing. Recent progress in display technology has allowed for the tagging multiple stimuli simultaneously at >60Hz frequencies - high enough to evade perceptibility, while still evoking an oscillatory response. Known as Rapid Invisible Frequency Tagging (RIFT), this technique currently only been used combination with Magnetoencephalography (MEG), which is less accessible compared...
(2019) and demonstrate that this assumption may not hold. The gaze bias instead reveals participants might deploy an alternative spatial-based strategy, memorizing the endpoint locations of bars, thereby allowing them to solve task without orientations. Although we do call into question conclusion internal attention is inherently spatially organized, our results imply directional microsaccade biases also reflect directed at taskrelevant, location-specific stimulus properties, rather than...
It is commonly assumed that one eye dominant over the other eye. Eye dominance most frequently determined by using hole-in-the-card test. However, it currently unclear whether as test (so-called sighting dominance) generalizes to tasks involving interocular conflict (engaging sensory dominance). We therefore investigated linked in several used paradigms involve conflict. was measured test, binocular rivalry, and breaking continuous flash suppression (b-CFS). Relationships between differences...
Visual stimuli with social-emotional relevance have been claimed to gain preferential access awareness. For example, recent studies used the breaking continuous flash suppression paradigm (b-CFS) show that faces are perceived as less dominant and more trustworthy prioritized for Here we asked whether these effects truly reflect differences in meaning or they can be equally explained by low-level stimulus properties. In Experiment 1, successfully replicated dominance-...
Abstract Sensory input is inherently noisy while the world predictable. When multiple observations of same object are available, integration available information necessarily increases reliability a estimate. Optimal instances sensory evidence has already been demonstrated during multisensory perception but could benefit unimodal as well. In present study 330 participants observed sequence four orientations and were cued to report one them. Reports biased by all simultaneously memorized...
Visual working memory (VWM) is a store for temporary maintenance of visual information. It often disregarded, though, that information typically stored to enable actions. Therefore, the context these actions great importance how VWM used. Here, we questioned whether severity consequence an action might affect well memorized, and cautiously it utilized. We employed (online) copying task, in which participants reproduced example display comprised six items grid, using pool items. Crucially,...
