THE MIDDLE GETS A NAME
This seems to be an appropriate time to give the middle type a name. Some have suggested “equimorph” to fit Sheldon’s terminology. After trying out several terms this seems to be as good as any. It suggests an equality of the three main dimensions.
While three numbers may be sufficient to classify a body according to Sheldon’s schema, a fourth number or index indicating the degree of EQUIMORPHY is needed to get a full picture of the factors making up temperament. The Equimorph index follows Sheldon in using a scale of 1 to 7, with “7” representing equality of all three systems. I place the index of EQUIMORPHY in parentheses after the usual three numbers that are given to locate a somatotype. The parentheses is a reminder that, although it is an important component of temperament, it is not an actual extreme, but is derived from the three main physical dimensions of a physique. A somatotype ordinarily given as a 4,4,4 would be written 4,4,4,(7) indicating the maximum state of balance. A 1,1,7 would become 1,1,7,(1) indicating the maximum distance from the center. Other somatotypes would be located between these extremes on the Equimorphy scale. Simply stated it is an expression of the degree of balance between endomorphy, mesomorphy and ectomorphy.
WHAT DO ALL THESE NUMBERS MEAN?
I have suggested that Sheldon’s schema can be used to establish the order of dominance
of the four organismic systems. This means that there are twenty-
The process of deciphering the meaning of the twenty-
The first system represents what the organism wants. The last system represents
what the organism wants to avoid. The second system is how the organism gets what
it wants. The third system is kind of neutral and may rarely emerge in a situation
of leisure or it may be the last defense against what it doesn’t want. There is
a body of research carried out by the Russian disciple of Pavlov, -
“Every holistic activity of the organism has a tendency
to be the only one present at a given time and to exclude
all other acts. The organism cannot combine simultaneously
two or three holistic activities.” Anokhin, P.K. (1965), In: Russian monographs on brain and behavior no. 3. Orienting reflex and exploratory behavior. Ed. American Institute of Biological Sciences, Washington.
The dominant system under a time-
1. What a person wants.
2. How a person gets what they want.
3. What a person may do if time is available.
4. What a person avoids.
Here are some examples of how the types would be abbreviated and organized.

N = Nervous System O = Orientational System

On this site, don’t expect to find the lengthy personality sketches that you may
find in many personality systems. Instead we will present personality “themes” that
summarize the core of a person’s behavior. Although it may be entertaining to read
something like Kiersey’s or the Myers-
INTERPRETING THE BASIC MEANINGS OF THE SYSTEMS.
As we try to interpret the effect of each combination of the four systems, we want
to stay as true as possible to the language of the body’s structure. This will naturally
limit what we can say and this is why complex sketches of people aren’t practical
at this point. Some day when there is data for a couple hundred of each combination
it should be possible to achieve extraordinary insight about each permutation. That
doesn’t mean that individuals can’t benefit immediately. The simple themes should
be an adequate guide for self-
There are two things we need to understand about the systems. First of all we need
to know the purpose of each system. In other words, we need to know the desired
state a system wants. Let’s imagine we could converse with each system and ask -
Here is a summary of these key “state” words:
1. “Visceral System, what is the one word that describes the state you are desiring?
Answer: UNITY
2. “Muscular System, what is the one word that describes the state you are desiring?
Answer: CONTROL
3. “Nervous System, what is the one word that describes the state you are desiring?
Answer: IDENTITY
4. “Orientational System, what is the one word that describes the state you are desiring?
Answer: CHANGE
Second, we need to understand what each system does. It’s as if we could ask each
system -
Here is a summary of these key “action” words:
1. “Visceral System, in just one word what are you doing?”
Answer: WAITING
2. “Muscular System, in just one word what are you doing?
Answer: WORKING
3. “Nervous System, in just one word what are you doing?
Answer: PLANNING
4. “Orientational System, in just one word what are you doing?
Answer: SEARCHING
