Sequences and Plans
Sequences, plans and cause-effect concepts are rooted in movement and
journey metaphors. The term "linear' has become popular to describe behavior
that is goal oriented and sequential. The shortest journey between two points is
a line. Linear thinking is supposed to be analytical and some even claim it
occurs on one side of the brain and not on the other. The opposite of linear
thinking is supposed to be spatial, somehow multidimensional and freer than
Speculations about hemispheric specialization in terms of linear-analytic
and spatial-artistic are misleading. If you understand that the root sequencing
ability in all animals has to do with moving around in complicated and somewhat
dangerous spaces, then thinking about sequences and plans becomes more
productive. Everyone who goes to the store to buy groceries has a goal and a
plan. The plan is implemented by following a sequence of steps. If you have gone
to get groceries many times the sequence is stored in memory and you do not have
to think about it. We can describe your plan as intuitive, spatial and holistic;
you just go to the store and get groceries.
If you are new to town and this is your first trip, your strategy is quite
different. Going shopping for the first time is different from going the tenth
time. A good idea is to get directions from someone who has gone to the store
many times. They tell you how to get there and they may draw you a map showing
the waypoints along your path. Males prefer a map and females prefer verbal
instructions that emphasize landmarks as waypoints. Waypoints, as every
navigator knows, are intermediate destinations along a travel path that allow
you to confirm that you are heading in the right direction. Some waypoints are
decision points. You have to identify a landmark and decide to turn left or
Some would describe implementing the first trip to the store as “linear
and analytic” because you need more conscious effort; the directions and the
sequence you follow may have to be written down in words and recorded in a
diagram that shows lines connecting A to B to C.
Most human sequences follow the same pattern of transforming from “linear and
analytic” as you learn into “synthetic after you have practiced a great deal.
Practice and experience transform "linear analytic” tasks into “spatial
The brain works harder and operates differently when the task is new.
Modules in both sides of the brain are active with every new sequence; when the
sequence is practiced repeatedly, brain activation becomes more efficient, more
localized and sometimes more lateralized. Another observation is that
younger brains are more efficient and older brains are less efficient, using
more diffuse and bilateral processing to solve problems.
