Concentration of Attention!..
Nearly everyone has difficulty in
the concentration of attention. Brain workers in business and
industry, students in high school and college, and even
professors in universities, complain of the same difficulty.
Attention seems in some way to be at the very core of mental
activity, for no matter from what aspect we view the mind, its
excellence seems to depend upon the power to concentrate
attention.
When we examine a growing infant, one of the first
signs by which we judge the awakening of intelligence is the
power to pay attention or to "notice things."
When we examine the intellectual
ability of normal adults we do so by means of tests that require
close concentration of attention. In judging the intelligence of
people with whom we associate every day, we regard one who is
able to maintain close attention for long periods of time as a
person of strong mind.
We rate Thomas Edison as a powerful
thinker when we read that he becomes so absorbed in work that he
neither eats nor sleeps. Finally, when we examine the insane and
the feeble-minded, we find that one form which their
derangements take is an inability to control the attention.
This
evidence, added to our own experience, shows us the importance
of concentration of attention in study and we become even more
desirous of investigating attention to see how we may develop
it.
We shall be better able to
discuss attention if we select for analysis a concrete situation
when the mind is in a state of concentrated attention.
Concentrate for a moment upon the letter O.
Although you are
ostensibly focusing all your powers of attention upon the
letter, nevertheless you are really aware of a number of things
besides: of other words on the page; of other objects in the
field of vision; of sounds in the room and on the street; of
sensations from your clothing; and of sensations from your
bodily organs, such as the heart and lungs.
In addition to these sensations,
you will find, if you introspect carefully enough, that your
mind also contains a number of ideas and imaginings; thoughts
about the paragraph you just read or about one of your lessons.
Thus we see that at a time when we apparently focus our
attention upon but one thing, we really have a large number of
things in our mind, and they are of a great variety.
The mental
field might be represented by a circle, at the centre of which
is the object of attention. It may be an object in the external
world perceived through one of the senses, or it may be an idea
we are thinking about, such, for example, as the idea of
infinity.
But whether the thing attended to is a perception or
an idea, we may properly speak of it as the object of attention
or the "focal" object. In addition to this, we must recognize
the presence of a large number of other objects, both sensory
and ideational. These are nearer the margin of the mental field,
so we call them "marginal."
The distinctive thing about a
state of mind such as that just described is that the focal
object is much clearer than the marginal objects.
For example,
when you fixated the letter O, it was only in the vaguest sort
of fashion that you were aware of the contact of your clothing
or the lurking ideas of other lessons. As we examine these
marginal objects further, we find that they are continually
seeking to crowd into the centre of attention and to become
clear.
You may be helped in forming a vivid picture of
conditions if you think of the mind as a stream ever in motion,
and as it flows on, the objects in it continually shift their
positions. A cross-section of the stream at any moment may show
the contents of the mind arranged in a particular pattern, but
at the very next moment they may be arranged in a different
pattern, another object occupying the focus, while the previous
tenant is pushed to the margin.
Thus we see that it is a
tendency of the mind to be forever changing. If left to itself,
it would be in ceaseless fluctuation, the whim of every passing
fancy.
This tendency to fluctuate comes with more or less
regularity, some psychologists say every second or two. True, we
do not always yield to the fluctuating tendency, nevertheless we
are recurrently tempted, and we must exercise continuous effort
to keep a particular object at the focus. The power to exert
effort and to regulate the arrangement of our states of mind is
the peculiar gift of man, and is a prime function of education.
Viewed in this light, then, we see that the voluntary focusing
of our attention consists in the selecting of certain objects to
be attended to, and the ignoring of other objects which act as
distractions. We may conveniently classify the latter as
external sensations, bodily sensations and irrelevant ideas.
Let us take an actual situation
that may arise in study and see how this applies. Suppose you
are in your room studying about Charlemagne, a page of your
history text occupying the centre of your attention.
The
marginal distractions in such a case would consist, first, in
external sensations, such as the glare from your study-lamp, the
hissing of the radiator, the practicing of a neighboring
vocalist, the rattle of passing street-cars. The bodily
distractions might consist of sensations of weariness referred
to the back, the arms and the eyes, and fainter sensations from
the digestive organs, heart and lungs.
The irrelevant ideas might consist of thoughts about a German lesson which you are going to study, visions of a face, or thoughts about some social engagement. These marginal objects are in the mind even when you conscientiously focus your mind upon the history lesson, and, though vague, they try to force their way into the focus and become clear.
The task of paying attention,
then, consists in maintaining the desired object at the centre
of the mental field and keeping the distractions away. With this
definition of attention, we see that in order to increase the
effectiveness of attention during study, we must devise means
for overcoming the distractions peculiar to study.
Obviously the
first thing is to eliminate every distraction possible. Such a
plan of elimination may require a radical rearrangement of study
conditions, for students often fail to realize how wretched
their conditions of study are from a psychological standpoint.
They attempt to study in rooms with two or three others who talk
and move about continually; they drop down in any spot in the
library and expose themselves needlessly to a great number of
distractions.
If you wish to become a good
student, you must prepare conditions as favorable as possible
for study. Choose a quiet room to live in, free from distracting
sounds and sights.
Have your room at a temperature neither too
hot nor too cold; 68° F. is usually considered favorable for
study. When reading in the library, sit down in a quiet spot,
with your back to the door, so you will not be tempted to look
up as people enter the room. Do not sit near a group of
gossipers or near a creaking door.
Having made the external
conditions favorable for study, you should next address yourself
to the task of eliminating bodily distractions. The most
disturbing of these in study are sensations of fatigue, for,
contrary to the opinion of many people, study is very fatiguing
work and involves continual strain upon the muscles in holding
the body still, particularly those of the back, neck, arms,
hands and, above all, the eyes.
How many movements are made by
your eyes in the course of an hour's study! They sweep back and
forth across the page incessantly, being moved by six muscles
which are bound to become fatigued. Still more fatigue comes
from the contractions of delicate muscles within the eyeball,
where adjustments are made for far and near vision and for
varying amounts of light. The eyes, then, give rise to much
fatigue, and, altogether, are the source of a great many bodily
distractions in study.
Other distractions may consist of sensations from the clothing. We are always vaguely aware of pressure of our clothing. Usually it is not sufficiently noticeable to cause much annoyance, but occasionally it is, as is demonstrated at night when we take off a shoe with such a sigh of relief that we realize in retrospect it had been vaguely troubling us all day.
In trying to create conditions
for efficient study, many bodily distractions can be eliminated.
The study chair should be easy to sit in so as to reduce fatigue
of the muscles supporting the body; the book-rest should be
arranged so as to require little effort to hold the book; the
light should come over the left shoulder.
This is especially
necessary in writing, so that the writing hand will not cast a
shadow upon the work. The muscles of the eyes will be rested and
fatigue will be retarded if you close the eyes occasionally.
Then in order to lessen the general fatigue of the body, you may
find it advantageous to rise and walk about occasionally.
Lastly, the clothing should be loose and unconfining; especially
should there be plenty of room for circulation.
In the overcoming of
distractions, we have seen that much may be done by way of
eliminating distractions, and we have pointed out the way to
accomplish this to a certain extent.
But in spite of our most
careful provisions, there will still be distractions that cannot
be eliminated. You cannot, for example, chloroform the vocalist
in the neighboring apartment, nor stop the street-cars while you
study; you cannot rule out fatigue sensations entirely, and you
cannot build a fence around the focus of your mind so as to keep
out unwelcome and irrelevant ideas.
The only thing to do then is
to accept as inevitable the presence of some distractions, and
to realize that to pay attention, it is necessary to habituate
yourself to the ignoring of distractions.
In the accomplishment of this
end it will be necessary to apply the principles of habit
formation already described. Start out by making a strong
determination to ignore all distractions. Practise ignoring
them, and do not let a slip occur.
Try to develop interest in
the object of attention, because we pay attention to those
things in which we are most interested. A final point that may
help you is to use the first lapse of attention as a reminder of
the object you desire to fixate upon. This may be illustrated by
the following example: Suppose, in studying a history lesson,
you come upon a reference to the royal apparel of Charlemagne.
The word "royal" might call up purple, a Northwestern University
pennant, the person who gave it to you, and before you know it
you are off in a long day-dream leading far from the history
lesson. Such migrations as these are very likely to occur in
study, and constitute one of the most treacherous pitfalls of
student life. In trying to avoid them, you must form habits of
disregarding irrelevant ideas when they try to obtrude
themselves.
And the way to do this is to school yourself so that
the first lapse of attention will remind you of the lesson in
hand. It can be done if you keep yourself sensitive to
wanderings of attention, and let the first slip from the topic
with which you are engaged remind you to pull yourself back. Do
this before you have taken the step that will carry you far
away, for with each step in the series of associations it
becomes harder to draw yourself back into the correct channel.
In reading, one frequent cause
for lapses of attention and for the intrusion of unwelcome ideas
is obscurity in the material being read. If you trace back your
lapses of attention, you will often find that they first occur
when the thought becomes difficult to follow, the sentence
ambiguous, or a single word unusual.
As a result, the meaning
grows hazy in your mind and you fail to comprehend it.
Naturally, then, you drift into a channel of thought that is
easier to follow. This happens because the mental stream tends
to seek channels of least resistance. If you introspect
carefully, you will undoubtedly discover that many of your
annoying lapses of attention can be traced to such conditions.
The obvious remedy is to make sure that you understand
everything as you read.
As soon as you feel the thought growing
difficult to follow, begin to exert more effort; consult the
dictionary for the meanings of words you do not understand.
Probably the ordinary freshman in college ought to look up the
meaning of as many as twenty words daily.
Again, the thought may be difficult to follow because your previous knowledge is deficient; perhaps the discussion involves some fact which you never did comprehend clearly, and you will naturally fail to understand something built upon it. If deficiency of knowledge is the cause of your lapses of attention, the obvious remedy is to turn back and study the fundamental facts; to lay a firm foundation in your subjects of study.
This discussion shows that the
conditions at time of concentrated attention are very complex;
that the mind is full of a number of things; that your object as
a student is to keep some one thing at the focus of your mind,
and that in doing so you must continuously ignore other mental
contents.
In our psychological descriptions we have implied that
the mind stands still at times, permitting us to take a
cross-section and examine it minutely. As a matter of fact, the
mind never stands still. It continually moves along, and at no
two moments is it exactly the same. This results in a condition
whereby an idea which is at one moment at the centre cannot
remain there unless it takes on a slightly different appearance
from moment to moment.
When you attempted to fix your
attention upon the letter O, you found a constant tendency to
shift the attention, perhaps to a variation in the intensity of
the type or to a flaw in the type or in the paper. In view of
the inevitable nature of these changes, you see that in spite of
your best efforts you cannot expect to maintain any object of
study inflexibly at the centre of attention.
The way to do is to
manipulate the object so that it will appear from moment to
moment in a slightly different light. If, for example, you are
trying to concentrate upon a rule of English grammar long enough
to memorize it, do not read it over and over again, depending
solely upon repetition. A better way, after thoroughly
comprehending it, is to think about it in several relations;
compare it with other rules, noting points of likeness and
difference; apply it to the construction of a sentence.
The
essential thing is to do something with it. Only thus can you
keep it in the focus of attention. This is equivalent to the
restatement of another fact stressed in a previous chapter,
namely, that the mind is not a passive thing that stands still,
but an active thing.
When you give attention, you
actively select from a number of possible objects one to be
clearer than the rest. This selection requires effort under most
conditions of study, but you may be cheered by the thought that
as you develop interest in the fields of study, and as you
develop habits of ignoring distractions, you will be able to
fixate your attention with less and less effort.
A further
important fact is that as you develop power to select objects
for the consideration of attention, you develop simultaneously
other mental processes—the ability to memorize, to economize
time and effort and to control future thoughts and actions. In
short, power to concentrate attention means power in all the
mental processes.
