Perception3
Perceiving Motion
| Question | Answer |
|---|---|
| Apparent Motion | when at least to stimui are in slightly diffrent locations paired with correct timing, the observer percevies motion. (movies,tv, moving signs) |
| Real Motion | Actual movement of an object. |
| Induce Motion | occers when the motion of one object causes a nearby stationary object to appear to move. Ex: The moon(stationary) appears to move when the clouds(IN motion) move past it |
| Motion Aftereffects | occurafter viewing a moving stimulus for 30-60 sec and then viewing a stationary stimulus, which then appears to move. Ex:Waterfall Illusion |
| Waterfall Illusion | if you look at a water fall for 30-60sec then look away to a scene that is stationary then everything (rocks,trees, grass) aprear to move up for a few seconds. |
| Coherence | used to indicate the degree to which the dots move in the same direction(retina) |
| Corollary Discharge Theory | says the perceptual system uses a signal called the corollary discharge to take into the account the fact that the observere's eye in moving. |
| (MS)Motor Signals | The eye moves because of this signal being sent form the motor area of your brain to your eye muscles. |
| (CDS)Corollary Discharge Signal | A copy of the signal that is sent from the brain to the eye muscles. it is sent from the hyptherical comparator. |
| Comparator | Relays information back to the back of the brain that the eye is moving. |
| (IDS) Image Dispacement Signal | The signal tha occurs when an immage stimulates the receptors by moving across them. |
| Implied Motion | showing the observer a picture that dipicts a situation involving motion. the observer sees |
| Motion Agnosia | The inability to perceve motion caused by brain damage |
| Illusory motion | Perception of motion whne there actually is none |
| Local Disturbance in Optic Array | Occurs when on object moves reelitive to the environment,covering and uncovering the stationary background. |
| Golbal Optic Flow | information for movment that occurs when all eleements in a scene move. indicates that the observer is moving and not the scene |
| Real Motion Neuron | this neuron only responds when the stimulus moves |
| Point-Light Walker | stimuli created by placing small lights on people's joints and then filming the patterns created when moved in the dark |
| Representational Momentum | M |
