Surprising as
it may seem, it isn't capacity that explains the differences that exist
between individuals because most seem to have far more capacity than
they will ever use. The differences that exist between individuals seem
to be related to something else. The ones who achieve and out perform
others seem to have within themselves the ability to use hidden
resources. In other words, it's what they are able to do with what they
have that makes the difference.
In many
animal-breeding programs the entire process of selection and management
is founded on the belief that performance is inherited. Attempts to
analyze the genetics of performance in a systematic way have involved
some distinguished names such as Charles Darwin and Francis Galton. But
it has only been in recent decades that good estimates of heritability
of performance have been based on adequate data. Cunningham (1991) in
his study of horses found that only by using Timeform data, and
measuring groups of half brothers and half sisters could good estimates
of performance be determined. His data shows that performance for speed
is about 35% heritable. In other words only about 35% of all the
variation that is observed in track performance is controlled by
heritable factors, the remaining 65% are attributable to other
influences, such as training, management and nutrition. Cunningham's
work while limited to horses provides a good basis for understanding how
much breeders can attribute to the genetics and the pedigrees.
Researchers have studied this phenomena and have looked for new ways to
stimulate individuals in order to improve their natural abilities. Some
of the methods discovered have produced life long lasting effects.
Today, many of the differences between individuals can now be explained
by the use of early stimulation methods.
Introduction
Man for centuries has
tried various methods to improve performance. Some of the methods have
stood the test of time, others have not. Those who first conducted
research on this topic believed that the period of early age was a most
important time for stimulation because of its rapid growth and
development. Today, we know that early life is a time when the physical
immaturity of an organism is susceptible and responsive to a restricted
but important class of stimuli. Because of its importance many studies
have focused their efforts on the first few months of life.
Newborn pups
are uniquely different than adults in several respects. When born their
eyes are closed and their digestive system has a limited capacity
requiring periodic stimulation by their dam who routinely licks them in
order to promote digestion. At this age they are only able to smell,
suck, and crawl. Body temperature is maintained by snuggling close to
their mother or by crawling into piles with other littermates. During
these first few weeks of immobility researchers noted that these
immature and under-developed canines are sensitive to a restricted class
of stimuli which includes thermal, and tactile stimulation, motion and
locomotion.
Other mammals
such as mice and rats are also born with limitations and they also have
been found to demonstrate a similar sensitivity to the effects of early
stimulation. Studies show that removing them from their nest for three
minutes each day during the first five to ten days of life causes body
temperatures to fall below normal. This mild form of stress is
sufficient to stimulate hormonal, adrenal and pituitary systems. When
tested later as adults, these same animals were better able to withstand
stress than littermates who were not exposed to the same early stress
exercises. As adults, they responded to stress in "a graded"
fashion, while their non-stressed littermates responded in an "all
or nothing way."
Data involving
laboratory mice and rats also shows that stress in small amounts can
produce adults who respond maximally. On the other hand, the results
gathered from non-stressed littermate show that they become easily
exhausted and would near death if exposed to intense prolonged stress.
When tied down so they were unable to move for twenty-four hours, rats
developed severe stomach ulcers, but litter mates exposed to early
stress handling were found to be more resistant to stress tests and did
not show evidence of ulcers. A secondary affect was also noticed.
Sexual maturity
was attained sooner in the littermates given early stress exercises.
When tested for differences in health and disease, the stressed animals
were found to be more resistant to certain forms of cancer and
infectious diseases and could withstand terminal starvation and exposure
to cold for longer periods than their non-stressed littermates. Other
studies involving early stimulation exercises have been successfully
performed on both cats and dogs. In these studies, the Electrical
Encephalogram (EEG) was found to be ideal for measuring the electrical
activity in the brain because of its extreme sensitivity to changes in
excitement, emotional stress, muscle tension, changes in oxygen and
breathing. EEG measures show that pups and kittens when given early
stimulation exercises mature at faster rates and perform better in
certain problem solving tests than non-stimulated mates. In the higher
level animals the effect of early stimulation exercises have also been
studied. The use of surrogate mothers and familiar objects were tested
by both of the Kelloggs' and Dr. Yearkes using young chimpanzees. Their
pioneer research shows that the more primates were deprived of
stimulation and interaction during early development, the less able they
were to cope, adjust and later adapt to situations as adults.
While
experiments have not yet produced specific information about the optimal
amounts of stress needed to make young animals psychologically or
physiologically superior, researches agree that stress has value. What
also is known is that a certain amount of stress for one may be too
intense for another, and that too much stress can retard development.
The results show that early stimulation exercises can have positive
results but must be used with caution. In other words, too much stress
can cause pathological adversities rather than physical or psychological
superiority.
Methods
of Stimulation
The U.S. Military in their canine program developed a method that still
serves as a guide to what works. In an effort to improve the performance
of dogs used for military purposes, a program called "Bio
Sensor" was developed. Later, it became known to the public as the
"Super Dog" Program. Based on years of research, the military
learned that early neurological stimulation exercises could have
important and lasting effects. Their studies confirmed that there are
specific time periods early in life when neurological stimulation has
optimum results. The first period involves a window of time that begins
at the third day of life and lasts until the sixteenth day. It is
believed that because this interval of time is a period of rapid
neurological growth and development, and therefore is of great
importance to the individual.
The
"Bio Sensor" program was also concerned with early
neurological stimulation in order to give the dog a superior advantage.
Its development utilized six exercises which were designed to stimulate
the neurological system. Each workout involved handling puppies once
each day. The workouts required handling them one at a time while
performing a series of five exercises. Listed in order of preference the
handler starts with one pup and stimulates it using each of the five
exercises. The handler completes the series from beginning to end before
starting with the next pup. The handling of each pup once per day
involves the following exercises:
1. Tactical stimulation (between toes)
2. Head held erect
3. Head pointed down
4. Supine position
5. Thermal stimulation
|
1.
Tactile stimulation
Holding the pup in one hand, the handler gently stimulates
(tickles) the pup between the toes on any one foot using a
Q-tip. It is not necessary to see that the pup is feeling the
tickle. Time of stimulation 3 - 5 seconds.

2.
Head held erect
Using both hands, the pup is held perpendicular to the ground,
(straight up), so that its head is directly above its tail. This
is an upwards position. Time of stimulation 3 - 5 seconds
(Figure 2).
|
|
3.
Head pointed down
Holding the pup firmly with both hands the head is reversed and
is pointed downward so that it is pointing towards the ground.
Time of stimulation 3 - 5 seconds (Figure 3).

4.
Supine position
Hold the pup so that its back is resting in the palm of both
hands with its muzzle facing the ceiling. The pup while on its
back is allowed to sleep struggle. Time of stimulation 3-5
seconds. (Figure 4)
|
|
5.
Thermal stimulation
Use a damp towel that has been cooled in a refrigerator for at
least five minutes. Place the pup on the towel, feet down. Do
not restrain it from moving. Time of stimulation 3-5 seconds.

These
five exercises will produce neurological stimulations, none of which
naturally occur during this early period of life. Experience shows that
sometimes pups will resist these exercises, others will appear
unconcerned. In either case a caution is offered to those who plan to
use them. Do not repeat them more than once per day and do not extend
the time beyond that recommended for each exercise.
Over stimulation of the neurological system can have adverse and
detrimental results. These exercises impact the neurological system by
kicking it into action earlier than would be normally expected. The
result being an increased capacity that later will help to make the
difference in its performance. Those who play with their pups and
routinely handle them should continue to do so because the neurological
exercises are not substitutions for routine handling, play socialization
or bonding.
Benefits
of Stimulation
Five benefits have been observed in
canines that were exposed to the Bio Sensor stimulation exercises. The
benefits noted were:
- Improved
cardio vascular performance (heart rate)
- Stronger
heart beats
- Stronger
adrenal glands
- More
tolerance to stress and
- Greater
resistance to disease.
In
tests of learning, stimulated pups were found to be more active and were
more exploratory than their non- stimulated littermates over which they
were dominant in competitive situations. Secondary effects were also
noted regarding test performance. In simple problem solving tests using
detours in a maze, the non-stimulated pups became extremely aroused,
wined a great deal, and made many errors. Their stimulated littermates
were less disturbed or upset by test conditions and when comparisons
were made, the stimulated littermates were more calm in the test
environment, made fewer errors and gave only an occasional distress when
stressed.
Socialization
As each animal grows and develops three kinds of stimulation have been
identified that impact and influence how it will develop and be shaped
as an individual. The first stage is called early neurological
stimulation, and the second stage is called socialization. The first two
(early neurological stimulation and socialization) have in common a
window of limited time. When Lorenz, (1935) first wrote about the
importance of the stimulation process he wrote about imprinting during
early life and its influence on the later development of the individual.
He states that it was different from conditioning in that it occurred
early in life and took place very rapidly producing results which seemed
to be permanent. One of the first and perhaps the most noted research
efforts involving the larger animals was achieved by Kellogg &
Kellogg (1933). As a student of Dr. Kellogg's I found him and his wife
to have an uncanny interest in children and young animals and the
changes and the differences that occurred during early development.
Their history making study involved raising their own newborn child with
a new born primate. Both infants were raised together as if they were
twins. This study like others that would follow attempted to demonstrate
that among the mammals there are great differences in their speed of
physical and mental development. Some are born relatively mature and
quickly capable of motion and locomotion, while others are very
immature, immobile and slow to develop. For example, the Rhesus monkey
shows rapid and precocious development at birth, while the chimpanzee
and the other "great apes" take much longer. Last and slowest
is the human infant.
One of the earliest efforts to investigate and look for the
existence of socialization in canines was undertaken by Scott-Fuller
(1965). In their early studies they were able to demonstrate that the
basic technique for testing the existence of socialization was to show
how readily adult animals would foster young animals, or accept one from
another species. They observed that with the higher level animals it is
easiest done by hand rearing. When the foster animal transfers its
social relationships to the new species, researchers conclude that
socialization has taken place. Most researchers agree that among all
species, a lack of adequate socialization generally results in
unacceptable behavior and often times produces undesirable aggression,
excessiveness, fearfulness, sexual inadequacy, and indifference toward
partners.
Socialization studies
confirm that the critical periods for humans (infant) to be stimulated
are generally between three weeks and twelve months of age. For canines
the period is shorter, between the fourth and sixteenth week of age.
During these critical time periods two things can go wrong. First,
insufficient social contact can interfere with proper emotional
development which can adversely affected the development of the human
bond. The lack of adequate social stimulation, such as handling,
mothering and contact with others, adversely affects social and
psychological development.
Second, over mothering
can prevent sufficient exposure to other individuals, and situations
that have an important influence on growth and development. The
literature shows that humans and animals respond in similar ways when
denied minimal amounts of stimulation. In humans, the absence of love
and cuddling increases the risk of an aloof, distant, asocial or
sociopathic individual. Over mothering can also have its detrimental
effects. It occurs when a patient insulates the child from outside
contacts, or keeps the apron strings tight, thus limiting opportunities
to explore and interact. In the end, over mothering generally produces a
dependent, socially maladjusted and sometimes emotionally disturbed
individual.
The absence of outside
social interactions for both children and pups usually results in a lack
of adequate learning and social adjustment. Protected youngsters who
grow up in an insulated environment often times become sickly,
despondent, lacking in flexibility and unable to make simple social
adjustments. Generally, they are unable to function productively or to
interact successfully then they become adults. Owners who have busy life
styles with long and tiring work and social schedules often times cause
pets to be neglected. Left to themselves with only an occasional trip
out of the house or off of the property they seldom see other canines or
strangers and generally suffer from poor stimulation and socialization.
For many, the side effects of loneliness and boredom set-in. The
resulting behavior manifests itself in the form of chewing, digging, and
hard to control behavior (Battaglia).
It seems clear that small
amounts of stress followed by early socialization can produce beneficial
results. The danger seems to be in not knowing where the thresholds are
for over and under stimulation. Many improperly socialized youngsters
develop into older individuals unprepared for adult life, unable to cope
with its challenges, and interactions. Attempts to re-socialize them
when adults have only produced small gains. These failures confirm the
notion that the window of time open for early neurological and social
stimulation only comes once. After it passes, little or nothing can be
done to overcome the negative effects of too much or too little
stimulation.
The third and final stage
in the process of growth and development is called enrichment. Unlike
the first two stages it has no time limit and by comparison covers a
very long period of time. Enrichment is a term which has come to mean
the positive sum of experiences, which have a cumulative effect upon the
individual. Enrichment experiences typically involve exposure to a wide
variety of interesting, novel, and exciting experiences with regular
opportunities to freely investigate, manipulate, and interact with them.
When measured in later life, the results show that those reared in an
enriched environment tend to be more inquisitive and are more able to
perform difficult tasks. The educational TV program called Sesame Street
is perhaps the best known example of a children's enrichment program.
The results show that when tested, children who regularly watched this
program performed better than playmates who did not. Follow up studies
show that those who regularly watched Sesame tend to seek a college
education and when enrolled, performed better than playmates who were
not regular watchers of the Sesame Street Program.
There are numerous
children studies that show the benefits of enrichment techniques and
programs. Most focus on improving self-esteem and self-talk. Follow up
studies show that the enriched Sesame Street students when later tested
were brighter and scored above average and most often were found to be
the products of environments that contributed to their superior test
scores. On the other hand, those whose test scores were generally below
average, (labeled as dull) and the products of underprivileged or non-
enriched environments often times had little or only small amounts of
stimulation during early childhood and only minimal amounts of
enrichment during their developmental and formative years. Many were
characterized as children who grew up with little interaction with
others, poor parenting, few toys, no books and a steady diet of TV soap
operas.
A similar analogy
can be found among canines. All the time they are growing they are
learning because their nervous systems are developing and storing
information that may be of inestimable use at a later date. Studies by
Scott and Fuller confirm that non-enriched pups when given free choice
preferred to stay in their kennels. Other litter mates who were given
only small amounts of outside stimulation between five and eight weeks
of age were found to be very inquisitive and very active. When kennel
doors were left open, the enriched pups would come bounding out while
littermates who were not exposed to enrichment would remain behind. The
non-stimulated pups would typically be fearful of unfamiliar objects and
generally preferred to withdraw rather than investigate. Even well bred
pups of superior pedigrees would not explore or leave their kennels and
many were found difficult to train as adults. These pups in many
respects were similar to the deprived children. They acted as if they
had become institutionalized, preferring the routine and safe
environment of their kennel to the stimulating world outside their
immediate place of residence.
Regular trips to the
park, shopping centers and obedience and agility classes serve as good
examples of enrichment activities. Chasing and retrieving a ball on the
surface seems to be enriching because it provides exercise and includes
rewards. While repeated attempts to retrieve a ball provide much
physical activity, it should not be confused with enrichment exercises.
Such playful activities should be used for exercise and play or as a
reward after returning from a trip or training session. Road work and
chasing balls are not substitutes for trips to the shopping mall,
outings or obedience classes most of which provide many opportunities
for interaction and investigation.
Finally it seems clear
that stress early in life can produce beneficial results. The danger
seems to be in not knowing where the thresholds are for over and under
stimulation. However, the absence or the lack of adequate amounts of
stimulation generally will produce negative and undesirable results.
Based on the above it is fair to say that the performance of most
individuals can be improved including the techniques described above.
Each contributes in a cumulative way and supports the next stage of
development.
Conclusion
Breeders can now take advantage of the information available to improve
and enhance performance. Generally, genetics account of about 35% of the
performance but the remaining 65% (management, training, nutrition) can
make the difference. In the management category it has been shown that
breeders should be guided by the rule that it is generally considered
prudent to guard against under and over stimulation. Short of ignoring
pups during their first two months of life, a conservative approach
would be to expose them to children, people, toys and other animals on a
regular basis. Handling and touching all parts of their anatomy is also
necessary to learn as early as the third day of life. Pups that are
handled early and on a regular basis, generally do not become hand shy
as adults. Because of the risks involved in under stimulation a
conservative approach to using the benefits of the three stages has been
suggested based primarily on the works of Arskeusky, Kellogg, Yearkes
and the "Bio Sensor" program (later known as the "Super
Dog Program").
Both
experience and research have dominated the beneficial effects that can
be achieved via early neurological stimulation, socialization and
enrichment experiences. Each has been used to improve performance and to
explain the differences that occur between individuals, their
trainability, health and potential. The cumulative effects of the three
stages have been well documented. They best serve the interests of
owners who seek high levels of performance when properly used. Each has
a cumulative effect and contributes to the development and the potential
for individual performance.
