SKIN & BODY SENSES
SKIN SENSES COMPRISED OF:
PRESSURE TEMPERATURE PAIN
DETERMINED BY THE NUMBER OF PAIN RECPETORS IN A GIVEN AREA
NECK & BACK OF THE KNEE HAVE MANY
BODY SENSES KINESTHESIS
INFORMS BRAIN ABOUT THE POSITION AND MOTION OF THE BODY
VESTIBULAR SENSE INFORMS THE BRAIN AS TO THE
VERTICAL POSITION OF THE BODY

PERCEPTION
Rules of Perception
Closure The tendency to perceive a
complete or whole figure even when there are gaps in what your senses tell you
Figure-Ground Perception The perception of figures
against a background
Figure-Ground Perception
Proximity Tendency to group together
visual & auditory events that are near each other
Proximity
Similarity Tendency to group together
elements that seem alike
Similarity
Continuity
A third principle of perceptual organization is that of good continuity. This principle is that contours based on smooth continuity are preferred to abrupt changes of direction. Here, for instance, we are more likely to identify lines a-b and c-d crossing than to identify a-d and c-b or a-c and d-b as lines.
Continuity Tendency to group stimuli
into continuous patterns
Common Fate Tendency to perceive
objects that are moving together as belonging together
Stroboscopic Motion
Visual illusion in which the perception of motion is generated by the presentation of a series of stationary images in rapid succession
Flip book
Depth Perception Monocular Cues for Depth Monocular cues need only one
eye to be perceived and make objects on a 2-D surface appear to be 3-D
Ex. Artists using perspective, clearness, overlapping, shadowing, texture
Depth Perception Binocular Cues for Depth Binocular cues require both
eyes to see the effect
Perceptual Constancies
Size
Tendency to perceive an object as being of one size no matter how far away it is
Color
Tendency to perceive an object is equally bright even when the intensity of the light around it changes
Ex. – Shirts in the movie theatre
Brightness
Tendency to perceive an object as being equally as bright even when the intensity of the light around it changes
Shape
The knowledge that an object has the same shape no matter what angle it is perceived from
Shape Constancy
