Abstract Serial dependence is thought to promote perceptual stability by compensating for small changes of an object’s appearance across memory episodes. So far, it has been studied in situations that comprised only a single object. The question how we selectively create temporal several objects remains unsolved. In task, can be differentiated their to-be-memorized feature (content) as well accompanying discriminative features (context). We test whether congruent context features, addition...
In a review of two books on Catholic thinking nuclear weapons for Peace & Change, some long-term historical context is in order. 1954, nine years after the United States dropped atomic bombs Hiroshima and Nagasaki, Pope Pius XII delivered what at time was most precise statement Church's view weapons. an address to Congress World Medical Association, stated that "modern all-out warfare," or so-called ABC warfare (atomic, biological, chemical), could only be permitted when it absolutely...
Visual attention enables observers to select behaviorally relevant information based on spatial locations, features, or objects. Attentional selection is not limited physically present visual information, but can also operate internal representations maintained in working memory (WM) service of higher-order cognition. However, only little known about whether WM contents follows the same principles as sensory stimuli. To address this question, we investigated humans typically observed effects...
What might sound like the beginning of a joke has become an attractive prospect for many cognitive scientists: use deep neural network models (DNNs) as human behavior in perceptual and tasks. Although DNNs have taken over machine learning, attempts to them are still early stages. Can they versatile model class scientist's toolbox? We first argue why potential be interesting behavior. then discuss how that can more fully realized. On one hand, we cycle training, testing, revising needs...
Attention selects relevant information regardless of whether it is physically present or internally stored in working memory. Perceptual research has shown that attentional selection external better conceived as rhythmic prioritization than stable allocation. Here we tested this principle using processing internal representations held Participants memorized 4 spatial positions formed the end points 2 objects. One was cued for a delayed match-nonmatch test. When uncued were probed,...
Software is much more than just code. It time to confront the complexity of licenses, uses, governance, infrastructure and other facets software in science. Their influence ubiquitous yet overlooked.
Abstract Steady-state visual evoked potentials (SSVEPs) are widely used for brain-computer interfaces (BCIs) as they provide a stable and efficient means to connect the computer brain with simple flickering light. Previous studies focused on low-density frequency division multiplexing techniques, i.e. typically employing one or two light-modulation frequencies during single light stimulation. Here we show that it is possible encode information in SSVEPs excited by high-density multiplexing,...
Working memory enables the storage of few items for a short period time. Previous research has shown that in working cannot be accessed equally well, indicating they are held at least two different states with capacity limitations. However, it is unclear whether differences between due to limitations number can stored, or quality which stored. We employed sequential whole-report procedure where participants reported remembered orientation each four encoded Gabor patches. In addition, rated...
Working memory (WM) enables a rapid access to limited number of items that are no longer physically present. WM studies usually involve the encoding and retention multiple items, while probing single item only. Hence, little is known about how well can be reported from WM. Here we asked participants successively report each up 8 encoded Gabor patches Recall order was externally cued, stimulus orientations had reproduced on continuous dimension. Participants were able sequentially with an...
Abstract An ideal vision model accounts for behavior and neurophysiology in both naturalistic conditions designed lab experiments. Unlike psychological theories, artificial neural networks (ANNs) actually perform visual tasks generate testable predictions arbitrary inputs. These advantages enable ANNs to engage the entire spectrum of evidence. Failures particular models drive progress a vibrant ANN research program human vision.
Vision is widely understood as an inference problem. However, two contrasting conceptions of the process have each been influential in research on biological vision well engineering machine vision. The first emphasizes bottom-up signal flow, describing a largely feedforward, discriminative that filters and transforms visual information to remove irrelevant variation represent behaviorally relevant format suitable for downstream functions cognition behavioral control. In this conception,...
People with schizophrenia (PSZ) are impaired in attentional prioritization of non-salient but relevant stimuli over salient distractors during visual working memory (VWM) encoding. Conversely, guidance top-down attention by external predictive cues is intact. Yet, it unknown whether this preserved ability can help PSZ encode more information the presence distractors.
Abstract The action perspective on working memory suggests that representations are coded according to their specific temporal and behavioral task demands. This stands in contrast theories assume stored a task-agnostic format within “common workspace”. Here, we tested whether visual items memorized for different tasks separately from one another or show evidence of inter-item interference during concurrent maintenance, indicating common storage. In two experiments, combined framing (memorize...

Abstract Visual perception operates in an object-based manner, by integrating associated features via attention. Working memory allows a flexible access to limited number of currently relevant objects, even when they are occluded or physically no longer present. Recently, it has been shown that we compensate for small changes object’s feature over episodes, which can support its perceptual stability. This phenomenon was termed ‘serial dependence’ and mostly studied situations comprised only...

Working memory (WM) performance varies substantially among individuals but the precise contribution of different WM component processes to these functional limits remains unclear. By analyzing types responses in a spatial task, we recently demonstrated dissociation between confident and not-confident errors reflecting failures encoding maintenance, respectively. Here, use event-related brain potentials further explore this dissociation. Healthy participants performed delayed...
Studies that examined the effect of amphetamine or caffeine on spatial working memory (SWM) and verbal (VWM) have used various tasks. However, there are no studies span tasks (SSTs) to assess SWM caffeine, although some digit (DST) VWM. Previous reports also showed increasing dopamine increases psychosis-like experiences (PLE, schizotypy) scores which in turn negatively associated with WM performance people high schizotypy schizophrenia. Therefore, present study aimed examine influence...
Abstract Previous magnetoencephalography (MEG) studies have revealed gamma-band activity at sensors over parietal and fronto-temporal cortex during the delay phase of auditory spatial non-spatial match-to-sample tasks, respectively. While this was interpreted as reflecting memory maintenance sound features, we noted that task-related activation differences might been present already prior to onset sample stimulus. The study focused on interval between a visual cue indicating which feature be...
Abstract Studying the visual system with fMRI often requires using localizer paradigms to define regions of interest (ROIs). However, considerable interindividual variability cerebral cortex represents a crucial confound for group-level analyses. Cortex-based alignment (CBA) techniques reliably reduce macroanatomical variability. Yet, their utility has not been assessed field paradigms, which map specific parts within retinotopically organized areas. We evaluated CBA an attention-enhanced...
