                  Perception
   Perception is the process through which the
    information from outside environment is
    selected, received, organized and interpreted to
    make it meaningful.
   Perception is primarily an individual process
    so that different people may perceive an
    identical situation differently.
         Perception as a process
   Select
   Organize
   Interpret
   Retrieval
  Perceptual Selectivity: refers to the
tendency to select certain objects from the environment
 for attention such that these objects are consistent with
          our existing beliefs, values and needs.

  Perceptual organization

Perceptual organization is the process by which
we group outside stimuli into recognizable and
    identifiable patterns and whole objects
Important contributors to
 perceptual organization
Figure-ground: principle means that we tend to be attentive to
  such perceived objects that stand out against a background
Reversible figure-ground
     Perceptual grouping: our tendency to
     group several individual stimuli into a meaningful and
                      reconizable patterns

   Continuity: relates to the tendency to perceive objects as
    continuous patterns.
   Closure: the tendency to perceive objects as a whole, even
    some parts of the objects are missing.
   Proximity: states that a group of objects or people who are
    physically close to each other may be perceived as related to
    each other so that they stand out as one unit.
   Similarity: states that the greater the similarity among the
    objects or people, the greater the tendency to perceive them as
    a common group.
    Major influences on the perception
                 process
   The characteristics of the perceiver.
   The characteristics of the perceived.
   The characteristics of the situation.
