We present novel evidence showing that new self-relevant visual associations can affect performance in simple shape recognition tasks. Participants associated labels for themselves, other people, or neutral terms with geometric shapes and then immediately judged whether subsequent label-shape pairings were matched. Across 4 experiments there was a reliable self-prioritization benefit on response times perceptual sensitivity remained across different presentation contexts (with self, best...

One of the most pleasurable aspects video games is their ability to induce immersive experiences. However, there appears be a tentative conceptualization what an experience is. In this short review, we specifically focus on terms flow and immersion, as they are widely used applied definitions in game literature, whilst differences remain disputable. We critically review concepts separately proceed with comparison proposed differences. conclude that immersion do not substantially differ...

There is growing awareness across the neuroscience community that replicability of findings about relationship between brain activity and cognitive phenomena can be improved by conducting studies with high statistical power adhere to well-defined standardised analysis pipelines. Inspired recent efforts from psychological sciences, desire examine some foundational using electroencephalography (EEG), we have launched #EEGManyLabs, a large-scale international collaborative replication effort....

Personally relevant stimuli exert a powerful influence on social cognition. What is not yet fully understood, however, how early in the processing stream self-relevance influences decisional operations. Here we used shape-label matching task conjunction with electroencephalography and computational modeling to explore this issue. A theoretically important pattern of results was observed. First, standard self-prioritization effect emerged indicating that responses self-related items were...

The increased resolution of Quad Full High Definition (QFHD) offers significantly enhanced visual experience. However, the corresponding huge data throughput up to 530 Mpixels/s greatly challenges design real-time video decoder VLSI with extensive requirement on both DRAM bandwidth and computational power. In this work, a lossless frame recompression technique partial MB reordering scheme are proposed save access QFHD chip. Besides, pipelining parallelization techniques such as...

Debate exists about the time course of effect colour categories on visual processing. We investigated for two groups who differed in whether they categorised a blue-green boundary as same- or different-category to reliably-named blue and green colour. Colour differences were equated just-noticeable be equally discriminable. analysed event-related potentials these colours elicited passive oddball task categorical effects Support category was found 100 ms after stimulus onset, over frontal...

Prior claims that color categories affect perception are confounded by inequalities in the space used to equate same- and different-category colors. Here, we colors number of just-noticeable differences, measure event-related potentials (ERPs) these on a visual oddball task establish if perceptual or post-perceptual stages processing. Category effects were found from 200 ms after presentation, only ERP components reflect processes (e.g., N2, P3). The findings suggest processing, but do not...

We report two experiments showing that dynamically orienting our own face facilitates the automatic attraction of attention. had participants complete a cueing task where they to judge orientation lateralized target cued by central changed its orientation. Experiment 1 showed reliable effect from both self- and friend-faces at long stimulus onset asynchrony (SOA), however, self-faces exclusively generated spatial short SOA. In 2, event-related potential (ERP) data cues larger amplitudes in...

In a previous study, Egly, Driver, and Rafal (1994) observed both space-and object-based components of visual selective attention. However, the mechanisms underlying these two relationship between them are not well understood. present research, with similar paradigm, issues were addressed by manipulating cue validity. Behavioral results indicated presence under high validity, to Egly et al.'s study. addition, low space-based component was absent, whereas maintained. Further event-related...

Using electroencephalogram (EEG), we tested the hypothesis that association of a neutral stimulus with self would elicit ultra-fast neural responses from early top-down feedback modulation to late feedforward periods for cognitive processing, resulting in self-prioritization information processing. In two experiments, participants first learned three associations between personal labels (self, friend, stranger) and geometric shapes (Experiment 1) colors 2), then they judged whether...

Abstract Since at least the 17 th century there has been idea that are four simple and perceptually pure “unique” hues: red, yellow, green, blue, all other hues perceived as mixtures of these hues. However, sustained scientific investigation not yet provided solid evidence for a neural representation separates unique from colors. We measured event-related potentials elicited ‘intermediate’ in between them. find signature 230 ms after stimulus onset post-perceptual stage visual processing....

Event-related potentials were recorded to investigate the mechanisms of hierarchical processing and level-repetition effect. Participants identified targets that appeared at global, local, or both levels patterns. Reaction times showed global precedence effects. An occipital P1 wave was enhanced local relative targets.

An H.264/AVC HP video decoder is implemented in 90nm CMOS. Its maximum throughput reaches 4096×2160@60fps, which at least 4.3× higher than the state-of-the-art. By using partial MB reordering and lossless frame recompression, 51% of DRAM bandwidth reduced results 58% power saving. Meanwhile, various efficient parallelization techniques contribute to a core energy saving 54%.

Abstract The global precedence effect refers to the findings that responses are faster a structure than its local parts and slowed by incongruent information. We recorded high‐density event‐related potentials (ERPs) study role of enhanced selection in effect. Hierarchical stimuli were compound letters which either identical (homogeneous stimuli) or central letter was brighter (bright different color from others (red stimuli). Subjects asked attend pop‐out red bright during task whereas there...
