|
Who do objects appear when a person moves forward?
|
Objects move relative to the person in the opposite direction |
|
|
|
What kind of information does optic flow provide? |
The walker's direction and speed |
|
|
|
Akinetopsia |
Blindness to motion which can make it difficult to do actions because everything appears frozen |
|
|
|
Attentional capture |
the ability to attract attention |
|
|
|
Real motion |
Actual motion of an object |
|
|
|
Illusory motion |
perception of motion when there actually is none |
|
|
|
Apparent motion |
illusion of movement that occurs when two objects separated in space are presented rapidly, one after another, separated by a brief time interval |
|
|
|
Induced motion |
occurs when motion of one object causes a nearby stationary to appear to move |
|
|
|
Motion aftereffect |
occur when viewing a moving stimulus for 30 to 60 seconds causes a stationary stimulus to appear to move |
Waterfall illusion |
|
|
Optic array |
Structure created by the services, texture, and contours of the environment |
|
|
|
A local disturbance in the optic array |
occurs when one object moves relative to the environment so that they stationary background is covered and uncovered by the moving object |
|
|
|
Global optic flow |
Everything moves at once in response to movement of the observer's eyes or body |
|
|
|
Theory that explains motion perception as being determined both by movement of the image on the retina and by signals that indicate movement of the eyes |
Corollary discharge theory |
|
|
|
Signal that occurs when an image moves across receptors in the retina |
image displacement signal |
|
|
|
A copy of the motor signal that is sent to the eye muscles to cause movement of the eye |
corollary discharge theory |
|
|
|
The signal that is sent to the eye muscles when the observers moves or tries to move his or her eyes |
Motor signal |
|
|
|
The structure of the brain that receives both IDS and CDS |
Comparator |
|
|
|
Neuron that responds only when the stimulus moves and doesn't respond when the eyes move even though the stimulus on the retina is the same in both situations |
real motion neuron |
|
|
|
Stimulus perception relationship |
presenting a stimulus and determining whether motion is perceived |
|
|
|
Stimulus physiology relationship |
presenting a movement stimulus and measuring neural responding |
|
|
|
Physiology-perception relationship |
measuring the relationship between physiological responding and perception. |
|
|
|
Aperture problem |
View only a small portion of a larger stimulus can result in misleading information about the direction in which the stimulus is moving |
|
|
|
Where are the neurons that respond to the ends of the moving objects found |
Striate cortex |
|
|
|
Implied motion |
situation in which a still picture depicts an action involving motion |
|
|
|
Representation momentum |
the idea that the motion depicted in a picture tends to continue in the observer's mind |
|
