George suffers from chronic back pain. His doctor suggests that he try a form of the therapy in which electrical stimulation is applied to his back. He explains that stimulating large sensory nerves in the spinal cord can prevent the transmission of pain impulses to the brain and that it is an application of the...…. theory of pain.
Gate-control theory:
A gate in spinal cord permits, prevents pain signals from passing
The entity perceived to stand apart from the background. What is...?
Figure
What is color constancy?
The ability to perceive an object as the same color regardless of the environment OR DESPITE CHANGES IN SENSORY INFORMATION.
WHAT IS SHADOWING?
A MONOCULAR CUE TO DISTANCE WHERE SHADDOWS APPEAR ON THE PARTS OF OBJECTS THAT ARE MORE DISTANT
WHAT ARE THE OBSERVER CHARACTERISTICS AFFECTING PERCEPTION?
MOTIVATION AND EMOTION
VALUES
EXPECTATIONS
COGNITIVE STYLE
EXPERIENCE AND CULTURE
PERSONALITY
The amount of pain is result of interacting biological, psychological, and social factors. What is....?
Biopsychosocial theory
The background against which a figure appears. What is...?
Ground
What is brightness constancy?
The ability to keep an object’s brightness constant even though the amount of light reaching the retina changes.
One object, by partially blocking another, is perceived as being closer.
WHAT IS...?
INTERPOSITION
CUES TO SOUND LOCATION THAT REQUIRE JUST ONE EAR.
WHAT IS...?
MONAURAL CUES
We call the information that reaches our sensory receptors the proximal stimulus. TRUE OR FALSE?
TRUE
Our tendency to perceive objects as unchanging, even given changes in sensory stimulation; aids in recognition of objects under different circumstances.
WHAT IS...?
WHAT IS PERCEPTUAL CONSTANCY
The perception of object’s size doesn’t change, regardless of the change in distance from eye and size of image on retina.
What is...?SIZE CONSTANCY
The difference between views of both eyes. WHAT IS...?
RETINAL DISPARITY
CUES TO SOUND LOCATION THAT REQUIRES BOTH EARS WORKING TOGETHER.
WHAT IS...?
BINAURAL CUES
THE OBJECT ALONG WITH THE IMPORTANT PERCEPTUAL PROPERTIES IS CALLED THE DISTAL STIMULUS. TRUE OR FALSE?
TRUE
WHAT ARE THE DIFFERENT KINDS OF CONSTANCIES?
size constancy (e.g. guessing the height of a building; from memory and distance cues)
shape constancy (e.g. shape of a plate while viewing on an angle is still a circle)
brightness constancy (e.g. relative brightness of two objects is retained in different lightings)
Color constancy (e.g. a green plant at night)
What is the difference between a binocular cue and a monocular cue for depth perception?
Monocular cues (one eye alone can do)
Binocular cues (need both eyes)
What is an optical illusion?
When you perceive something inaccurately.
WHAT IS STROBOSCOPIC MOTION?
THE APPARENT MOVEMENT THAT RESULTS FROM FLASHING A SERIES OF STILL PICTURES IN RAPID SUCCESSION, AS IN A MOTION PICTURE.
What does the Gestalt psychology says?
“The whole is greater than the sum of the parts.”
What is shape constancy?
Once we know an object’s shape, we perceive it as always taking that form.
THE TENDANCY TO SEE AN OBJECT AS THE SAME SHAPE NO MATTER WHAT ANGLE IT IS VIEWED.
Objects seen at greater distances appear to be
smoother and less textured.
WHAT IS...?
Texture gradient
THE APPARENT MOVEMENT CAUSED BY FLASHING LIGHTS IN SEQUENCE.
WHAT IS.….?
THE PHI PHENOMENON
THE PERCEPTION THAT A STATIONARY OBJECT IS ACTUALLY MOVING.
WHAT IS...?
AUTOKINETIC ILLUSION
