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

6 Rules of Perception Closure Figure-Ground Perception Proximity Similarity Continuity Common Fate
ClosureThe 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. Which is which? What we perceive as a figure and what we perceive as a background influences our The Vase or Profile perception perception
Proximity Nearness of one item to another People tend to group together visual & auditory events that are near each other
Similarity Tendency to group together elements that seem alike Think of similar objects as belonging together
Continuity Tendency to group stimuli into continuous patterns People would rather see continuous patterns rather than disrupted onesA third principle of perceptual organization is that of good continuity. This principle is that contours based on smoothcontinuity are preferred to abrupt changes of direction. Here, for instance, we are more likely to identify lines a-b and c-dcrossing than to identify a-d and c-b or a-c and d-b as lines.
Common Fate Tendency to perceive objects that are moving together as belonging together Ex. - if you saw a group of runners it is assumed that they are running to the same place
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 Claymation Movies “Chicken Run” Gumby
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 Examples of these cues are perspective, clearness, overlapping, shadows, and motion parallax
Depth Perception Binocular Cues for Depth Binocular cues require both eyes to see the effect
Depth Perception Binocular Cues (Continued) Two cues for depth perception Retinal Disparity Convergence Both work related to the closeness of objects to the eyes http://dragon.uml.edu/psych/depth2.html
