Summary of "Perception of the speed of self-motion vs. object-motion: Another example of two modes of vision?"

We investigated the effect of reduced contrast on speed perception for two types of tasks: (a) the speed of a rotating image, an example of "object-motion," and (b) speed of travel when viewing wide-screen videos recorded from inside a car, an example of "self-motion." Both types of stimuli were presented over a range of spatial contrasts. The results showed that reduced contrast caused significant decreases of perceived speed for the rotating disk, replicating the well known Thompson Effect. Reduced contrast had inconsistent effects on perceived speed of self-motion, however, resulting in perception of faster self-motion at the lowest speed, slower self-motion at higher speeds, and no effect at intermediate speed. Although further research is needed, the differential effects of reduced contrast on perceived speed of object-motion vs. self-motion are consistent with evidence for two modes of vision.

A preference for visual speed during smooth pursuit eye movement.

Does the preference for visual speed extend to motion perception when the eye moves? Current evidence from psychophysics and neuroscience is limited to small patches of image motion and stationary fix...

Fast random motion biases judgments of visible and occluded motion speed.

Human sensitivity to speed differences is very high, and relatively high when one has to compare the speed of an object that disappears behind an occluder with a standard. Nevertheless, different spee...

The faster you decide, the more accurate localization is possible: Position representation of "curveball illusion" in perception and eye movements.

When the inside texture of a moving object moves, the perceived motion of the object is often distorted toward the direction of the texture's motion (motion-induced position shift), and such perceptua...

Sensory integration of apparent motion speed and vibration magnitude.

Tactile apparent motion can display directional information in an intuitive way. It can for example be used to give directions to visually impaired individuals, or for waypoint navigation while cyclin...

Medical and Biotech [MESH] Definitions

Motion of an object in which either one or more points on a line are fixed. It is also the motion of a particle about a fixed point. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

Disorder caused by motion, as sea sickness, train sickness, car sickness, air sickness, or SPACE MOTION SICKNESS. It may include nausea, vomiting and dizziness.

Physical motion, i.e., a change in position of a body or subject as a result of an external force. It is distinguished from MOVEMENT, a process resulting from biological activity.

The real or apparent movement of objects through the visual field.

The art, technique, or business of producing motion pictures for entertainment, propaganda, or instruction.
