CogLab: Apparent Motion - Cengage
2014年5月11日 · If the time between the offset of the first stimulus and the onset of the second stimulus (called the interstimulus interval or ISI) is very short, observers simply see two dots presented nearly simultaneously. If the ISI is very long, observers see one dot flash on and off and then the other flash on and off.
Apparent Motion - Hanover College
Apparent motion is the appearance of real motion from a sequence of still images. Apparent motion occurs whenever stimuli separated by time and location are actually perceived as a single stimulus moving from one location to another.
ISI produces reverse apparent motion - PubMed
A moving random-dot stimulus was presented in two sequential frames separated by an interstimulus interval (ISI) during which the field was spatially uniform with luminance equal to either the average luminance of the stimulus field (grey) or that of the black dots (black).
Visual interactions in the path of apparent motion - Nature
When a dim gray path that links the positions of the two motion tokens is briefly flashed during the blank interstimulus interval (ISI) of an apparent motion display, a strong sensation of...
ISI produces reverse apparent motion - ScienceDirect
1990年1月1日 · In this condition, grey ISIs reversed the reverse motion to produce a veridical perception. Finally, in Experiment 3, we examined whether the negative image that follows the stimulus offset was the source of the reversal in motion direction.
Apparent Motion Experiment - College of Health and Human …
Apparent motion is, by the way, the basis of movement in all television, movies, and computer animation. The screen actually shows a rapid succession of still images, the perceived motion is entirely "apparent" and illusory. This lab allows you see apparent motion in one of its simplest forms and to demonstrate Korte's law for yourself ...
Two-frame apparent motion presented with an inter-stimulus …
2018年12月13日 · Two successive image frames presented with a blank inter-stimulus interval (ISI) induce reversals of perceived motion in humans. This illusory effect is a manifestation of the temporal...
Two-frame apparent motion presented with an inter-stimulus …
2018年12月13日 · Two successive image frames presented with a blank inter-stimulus interval (ISI) induce reversals of perceived motion in humans. This illusory effect is a manifestation of the temporal properties of image filters embedded in the visual processing pathway.
Psychophysical properties of two-stroke apparent motion
Two-stroke apparent motion shares many of its empirical properties with ISI-reversal motion, so it should be amenable to the same explanation. Computational modeling is underway in our laboratory to establish whether the steady-state response of motion energy sensors to continuous presentation of the two-stroke sequence is consistent with the ...
Cortical dynamics of form and motion integration: Persistence, apparent ...
1996年1月1日 · The model explains how an illusory contour can move in apparent motion to another illusory contour or to a luminance-derived contour; how illusory contour persistence motion to the upper interstimulus interval (ISI) threshold for apparent motion; and how upper and lower ISI thresholds for seeing apparent motion between two flashes decrease with ...
