Perception Cast
 Gestalt
 psychologists searched for rules by which the brain organizes fragments
 of sensory data into gestalts (from the German word for “whole”), or 
meaningful forms. In pointing out that the whole is more than the sum of
 its parts, these researchers showed that we constantly filter sensory 
information and infer perceptions in ways that make sense to us. This 
truth remains valid, even though contemporary research demonstrates that
 sensation and perception are parts of a continuous information 
processing system, involving both bottom-up and top-down processing.
