Grouping
What principles explain how
we group individual elements
like dots into larger figures?
Figure-ground differentiation
is only one kind of organization
imposed by the mind on
stimulus patterns, although it
may well be the most pervasive
and fundamental in daily life.
The Gestalt psychologists
uncovered various other
principles that our minds use to
achieve spontaneous groupings
of elements or stimulus
components. To appreciate fully
the contribution a process of
internal organization makes to
what we perceive, it must first
be grasped that, logically, no
one region of a stimulus pattern
falling upon the retina belongs
to or is part of any other region.
Thus, even though one region
of the imageΓÇöΓÇôfor example, one
emanating from a surface of an
objectΓÇöΓÇôis adjacent to another
region that emanates from an
adjacent region of the same
object surface, these two
regions of the image have no
particular physical kinship to
one another. If they are
perceived as belonging to the
same object surface, it must be
because we impose that
organization. In doing so, we
recover the kinship that
obtains in the object.
