متن کاملFlash-lag effect: differential latency, not postdiction.
A continuously moving object typically is perceived to lead a flashed object in space when the two retinal images are physically aligned, a phenomenon known as the flashlag effect (1). Eagleman and Sejnowski (2) recently published data that they interpreted to disagree with a previous explanation of this phenomenon, the differential-latency hypothesis (3–7), and to support instead a postdiction...
متن کاملLatency differences and the flash-lag effect
The tendency for briefly flashed stimuli to appear to lag behind the spatial position of physically aligned moving stimuli is known as the flash-lag effect. Possibly the simplest explanation for this phenomenon is that transient stimuli are processed more slowly than moving stimuli. We tested this proposal using a task based upon the simultaneous tilt illusion. When an oriented stimulus is surr...
متن کاملMotion extrapolation is not responsible for the flash–lag effect
To achieve perceptual alignment between a flashed target and a moving one, subjects typically require the flashed target to be aligned with a position that the moving target will only reach some time after the flash (the flash-lag effect). We examined how the magnitude of this misalignment changes near an abrupt change in velocity. The magnitude of the misalignment turns out to depend on the ta...
متن کاملSimple differential latencies modulate, but do not cause the flash-lag effect.
When a brief static flash is presented in physical alignment with a moving target, the position of the flash can seem to lag behind that of the moving target. Various explanations exist. One of the most popular is the differential latency hypothesis. This assumes that neural latencies for moving stimuli are shorter than those for static stimuli. Accordingly, the flash lag would occur because pe...
