Experimental note on fading of briefly flashed lines.
A peripheral uniform stimulus on a uniform background tends to fade when a ring enclosing the stimulus is flashed briefly, indicating that neural signals external to the stimulus such as those from the ring or those from the background tend to inhibit the onset-response or after-discharge of the stimulus. In this study, a peripheral achromatic line was flashed briefly on an achromatic backgroun...
متن کاملThe effect of optokinetic nystagmus on the perceived position of briefly flashed targets
Stimuli flashed briefly around the time of an impending saccade are mislocalized in the direction of the saccade and also compressed towards the saccadic target. Similarly, targets flashed during pursuit eye movements are mislocalized in the direction of pursuit. Here, we investigate the effects of optokinetic nystagmus (OKN) on visual localization. Subjects passively viewed a wide-field drifti...
متن کاملEffects of ISI and flash duration on the identification of briefly flashed stimuli.
The identification accuracy of briefly flashed stimuli followed by an interstimulus interval (ISI) of variable length was compared to that obtained with longer flashes that prolonged the exposure of the stimulus throughout the ISI. The interval between the onset of the stimulus and the onset of the mask (stimulus onset asynchrony (SOA)) was the same in the two conditions. Consistent with a depe...
متن کاملGrouping and Recognition of Dot Patterns with Straight Offset Polygons
When the boundary of a familiar object is shown by a series of isolated dots, humans can often recognize the object with ease. This ability can be sustained with addition of distracting dots around the object. However, such capability has not been reproduced algorithmically on computers. We introduce a new algorithm that groups a set of dots into multiple non-disjoint subsets. It connects the d...
متن کاملRecognition and Memory for Briefly Presented Scenes
Three times per second, our eyes make a new fixation that generates a new bottom-up analysis in the visual system. How much is extracted from each glimpse? For how long and in what form is that information remembered? To answer these questions, investigators have mimicked the effect of continual shifts of fixation by using rapid serial visual presentation of sequences of unrelated pictures. Exp...
