[IV. THE FORMATION OF HABITS]
Habit in its simplest form is the tendency to do, think, or act as one has done, thought, or acted in the past. It is the tendency to repeat activities of all kinds. It is the tendency which makes one inclined to do the familiar action rather than a new one. In a broader sense, habit formation means learning. It is a statement of the fact that conduct is modifiable and that such modifications may become permanent.
The fact of learning depends physiologically on the plasticity of the nervous system. The neurones, particularly those concerned with intellectual life, are not only sensitive to nerve currents but are modified by them. The point where the greatest change seems to take place is at the synapses, but what this modification is, no one knows. There are several theories offered as explanations of what happens, but no one of them has been generally accepted, although the theory of chemical change seems to be receiving the strongest support at present. There can be no disagreement, however, as to the effects of this change, whatever it may be. Currents originally passing with difficulty over a certain conduction unit later pass with greater and greater ease. The resistance which seems at first to be present gradually disappears, and to that extent is the conduct modified. This same element of plasticity accounts for the breaking of habits. In this case the action is double, for it implies the disuse of certain connections which have been made and the forming of others; for the breaking of a bad habit means the beginning of a good one.
The plasticity of neurone groups seems to vary in two respects--as to modifiability and as to power to hold modifications. The neurone groups controlling the reflex and physiological operations are least easily modified, while those controlling the higher mental processes are most easily modified. The neurone groups controlling the instincts hold a middle place. So far as permanence goes, connections between sensorimotor neurone groups seem to hold modifications longer than do connections between either associative-motor or associative-association.
It is probably because of this fact that habit in the minds of so many people refers to some physical activity. Of course this is a misconception. Wherever the nervous system is employed, habits are formed. There are intellectual, moral, emotional, temperamental habits, just as truly as physical habits. In the intellectual field every operation that involves association or memory also involves habits. Good temper, or the reverse, truthfulness, patriotism, thoughtfulness for others, open-mindedness, are as much matters of learning and of habit as talking or skating or sewing. Habit is found in all three lines of mental development: intellect, character, and skill.
Not only does the law of habit operate in all fields of mental activity, but the characteristics which mark its operation are the same. Two of these are important. In the first place, habit formation results in a lessening of attention to the process. Any process that is habitual can be taken care of by a minimum of attention. In other words, it need no longer be in the focal point, but can be relegated to the fringe. At the beginning of the modification of the neurone tract focal attention is often necessary, but as it progresses less and less attention is needed until the activity becomes automatic, apparently running by itself. Not all habits reach this stage of perfection, but this is the general tendency. This lessening of the need for attention means that less energy is used by the activity, and the individual doing the work is less likely to be fatigued. In the second place, habit tends to make the process more and more sure in its results. As the resistance is removed from the synapses, and the one particular series of units come to act more and more as a unit, the current shoots along the path with no sidetracking, and the act is performed or the thought reached unwaveringly with very little chance of error. If the habit being formed is that of writing, the appropriate movements are made with no hesitation, and the chances that certain ones will be made the first time increase in probability. This means a saving of time and an increase in confidence as to the results.
A consideration of these characteristics of habits makes clear its dangers as well as its values. The fact that habit is based on actual changes which take place in the nervous system, that its foundation is physical, emphasizes its binding power. Most people in talking and thinking of habit regard it as something primarily mental in nature and therefore believe all that is necessary to break any habit is the sufficient exercise of will power. But will power, however strong, cannot break actual physical connections, and it is such connections that bind us to a certain line of activity instead of any other, when once the habit is formed. It is just as logical to expect a car which is started on its own track to suddenly go off on to another track where there is no switch, as to expect a nerve current traveling along its habitual conduction unit to run off on some other line of nervous discharge. Habit once formed binds that particular line of thought to action, either good or bad. Of course habits may be broken, but it is a work of time and must result from definite physical changes. Every habit formed lessens the likelihood of any other response coming in that particular situation. Every interest formed, every act of skill perfected, every method of work adopted, every principle or ideal accepted, limits the recognition of any other possible line of action in that situation. Habit binds to one particular response and at the same time blinds the individual to any other alternative. The danger of this is obvious. If the habits formed are bad or wasteful ones, the individual is handicapped in his growth until new ones can be formed. On the other hand, habit makes for limitation.
Despite these dangers, habit is of inestimable value in the development of both the individual and the human race. It is through it that all learning is possible. It makes possible the preservation of our social inheritance. As James says, "Habit is the enormous fly-wheel of society, its most precious conservative agent." Because of its power of limitation it is sometimes considered the foe of independence and originality, but in reality it is the only road to progress. Other things being equal, the more good habits a person has, the greater the probability of his doing original work. The genius in science or in art or in statesmanship is the man who has made habitual many of the activities demanded by his particular field and who therefore has time and energy left for the kind of work that demands thinking. Habit won't make a genius, but all men of exceptional ability excel others in the number and quality of their habits in the field in which they show power. As the little child differs from the adult in the number and quality of his habits, so the ordinary layman differs from the expert. It is scarcity, not abundance, of habits that forces a man into a rut and keeps him mediocre. Just as the three year old, having taken four or five times as long as the adult to dress himself, is tired out at the end of the task, so the amateur in literature or music or morals as compared with the expert. The more habits any one has in any line, the better for him, both from the standpoint of efficiency and productivity, provided that the habits are good and that among them is found the habit of breaking habits.
The two great laws of habit formation are the laws of exercise and effect. These laws apply in all cases of habit formation, whether they be the purposeless habits of children or the purposive habits of maturity. The law of exercise says that the oftener and the more emphatically a certain response is connected with a certain situation, the more likely is it to be made to that situation. The two factors of repetition and intensity are involved. It is a common observance that the oftener one does a thing, other things being equal, the better he does it, whether it be good or bad. Drill is the usual method adopted by all classes of people for habit formation. It is because of the recognition of the value of repetition that the old maxim of "Practice makes Perfect" has been so blindly adhered to. Practice may make perfect, but it also may make imperfect. All that practice can do is to make more sure and automatic the activity, whatever it is. It cannot alone make for improvement. A child becomes more and more proficient in bad writing or posture, in incorrect work in arithmetic and spelling, with practice just as truly as under other conditions he improves in the same activities. Evidence from school experiments, which shows that as many as 40 per cent of the children examined did poorer work along such lines in a second test than in the first which had been given several months earlier, bears witness to the inability of mere repetition to get "perfect" results. To get such results the repetition must be only of the improvements. There must be a constant variation towards the ideal, and a selection of just those variations for practice, if perfect as well as invariable results are to be obtained.
The amount of repetition necessary in the formation of any given habit is not known. It will, of course, vary with the habit and with the individual, but experimental psychology will some day have something to offer along this line. We could make a great saving if we knew, even approximately, the amount of practice necessary under the best conditions to form some of the more simple and elementary habits, such as learning the facts of multiplication.
One other fact in connection with repetition should be noted, namely, that the exercise given any connection by the learner, freely, of his own initiative counts more than that given under purposive learning. This method of learning is valuable in that it is incidental and often saves energy and possible imitation on the part of the child, but it has certain drawbacks. Habits formed this way are ingrained to such an extent that they are very difficult to modify. They were not consciously attended to when they were formed, and hence it is difficult later to raise them to the focal point. Hence it is best whenever habits are partial and will need to be modified later, or when the habits must later be rationalized, or when bad habits must be broken, to have the process focalized in attention. The methods of gaining attention have already been discussed.
In the second place, if the habit being formed is connected with an instinct, the element of intensity is added. This, of course, means that a connection already made and one which is strongly ready to act is made to give its support to the new connection being formed. Of course the instinct chosen for this purpose must be in accord with the particular habit and with the nature of the learner. They may vary from the purely personal and physical up to those which have to do with groups and intellectual reactions. The added impetus of the instinct hastens the speed of the direction or supervision. The psychology of the value of self-activity is operative. It should be borne in mind, however, that the two kinds of exercise must be of the same degree of accuracy if this better result in self-initiated practice is to be obtained.
Not only is it true that repetition makes for automaticity, but intensity is also an aid. Connections which are made emphatically as well as often tend to become permanent. This is particularly true of mental habits. There are two factors of importance which make for intensity in habit formation. First, the focalization of attention on the connections being made adds intensity. Bagley in his discussion of this topic makes "focalization in attention" a necessity in all habits. Although habits may be formed without such concentration, still it is true that if attention is given to the process, time is saved; for the added intensity secured increases the speed of learning. In certain types of habits, however, when incidental learning plays a large part, much skill may be acquired without focalization of attention in the process. Much of the learning of little children is of this type. Their habits of language, ways of doing things, mannerisms, and emotional attitudes often come as a result of suggestion and imitation rather than as a result of definite formation of the new habit.
The second great law of habit formation is the law of effect. This law says that any connection whose activity is accompanied by or followed by satisfaction tends thereby to be strengthened. If the accompanying emotional tone is annoyance, the connection is weakened. This law that satisfaction stamps connections in, and annoyance inhibits connections, is one of the greatest if not the greatest law of human life. Whatever gives satisfaction, that mankind continues to do. He learns only that which results in some kind of satisfaction. Because of the working of this law animals learn to do their tricks, the baby learns to talk, the child learns to tell the truth, the adult learns to work with the fourth dimension. Repetition by itself is a wasteful method of habit formation. The law of effect must work as well as the law of exercise, if the results are to be satisfactory. As has already been pointed out, it is not the practice alone that makes perfect, but the stressing of improvements, and that fixing is made possible only by satisfaction. Pleasure, in the broad sense, must be the accompaniment or the result of any connection that is to become habitual. This satisfaction may be of many different sorts, physical, emotional, or intellectual. It may be occasioned by a reward or recognition from without or by appreciation arising from self-criticism. In some form or other it must be present.
Two further suggestions in habit formation which grow out of the above laws should be borne in mind. The first is the effect of primacy. In everyday language, "first impressions last longest." The character of the first responses made in any given situation have great influence on all succeeding responses. They make the strongest impression, they are the hardest to eradicate. From a physiological point of view the explanation is evident. A connection untraversed or used but a few times is much more plastic than later when it has been used often. Hence the first time the connection is used gives a greater set or bent than any equal subsequent activity. This is true both of the nervous system as a whole and of any particular conduction unit. Thus impressions made in childhood count more than those of the same strength made later. The first few attempts in pronouncing foreign words fixes the pronunciation. The first few weeks in a subject or in dealing with any person influences all subsequent responses to a marked degree.
The second suggestion has to do with the effect of exceptions. James says, "Never allow an exception to occur" in the course of forming a habit. Not only will the occurrence of one exception make more likely its recurrence, but if the exception does not recur, at least the response is less sure and less accurate than it otherwise would be. It tends to destroy self-confidence or confidence in the one who allowed the exception. Sometimes even one exception leads to disastrous consequences and undoes the work of weeks and months. This is especially true in breaking a bad habit or in forming a new one which has some instinctive response working against it.
There has been a great deal of work done in experimental laboratories and elsewhere in the study of the formation of particular habits. The process of habit formation has been shown by learning curves. When these learning curves are compared, it becomes clear that they have certain characteristics in common. This is true whether the learning be directed to such habits as the acquisition of vocabularies in a foreign language or to skill in the use of a typewriter. Several of the most important characteristics follow.
In the first place it is true of all learning that there is rapid improvement at first. During the beginning of the formation of a habit more rapid advance is made than at any other time. There are two principal reasons for this fact. The adjustments required at the beginning are comparatively simple and easily made and the particular learning is new and therefore is undertaken with zest and interest. After a time the work becomes more difficult, the novelty wears off, therefore the progress becomes less marked and the curve shows fluctuations.
Another characteristic of the learning curve is the presence of the so-called "plateaus." Plateaus show in the curve as flat, level stretches during which there has apparently been no progress. The meaning of these level stretches, and whether or not they can be entirely done away with in any curve, is a matter of dispute. These pauses may be necessary for some of the habits to reach a certain degree of perfection before further progress can be made. However this may be, there are several minor causes which tend to increase the number of plateaus and to lengthen the time spent in any one. In the first place an insecure or an inaccurate foundation must result in an increase of plateaus. If at the beginning, during the initial spurt, for instance, the learner is allowed to go so fast that what he learns is not thoroughly learned, or if he is pushed at a pace that for him makes thoroughness impossible, plateaus must soon occur in his learning curve. In the second place a fruitful cause of plateaus is loss of interest,--monotony. If the learner is not interested, he will not put forth the energy necessary for continued improvement, and a time of no progress is the result. The attitude of the learner toward the work is extremely important, not only in the matter of interest, but in the further attitude of self-confidence. Discouragement usually results in hindering progress, whereas confidence tends to increase it. The psychological explanation of this is very evident. Both lack of interest in the learning and the presence of discouragement are likely to result in divided attention and that, as has already been shown, results in unsatisfactory work. A third cause for plateaus is physiological. Not only must the learner be in the right attitude towards the work, but he must feel physically "fit." There seem to be certain physiological rhythms that may disturb the learning process whose cause cannot be directly determined, but generally the feeling of unfitness can be traced to a simple cause,--such as physical illness, loss of sleep, exercise, or food, or undue emotional strain.
The older psychology has left an impression that improvement in any function is limited both as to amount and as to the period during which it must be attained. The physiological limit of improvement has been thought of as one which was rather easily reached. The loss of plasticity of the nervous system has been supposed to be rather rapid, so that marked improvement in a habit after one has passed well into the twenties was considered improbable. Recent experiments, however, seem to show that no such condition of affairs exists. There is very great probability that any function whatsoever is improvable with practice, and in most cases to a very marked degree. To find a function which has reached the physiological limit has been very rare, even in experimental research, and even with extended practice series it has been unusual to reach a stage of zero improvement even with adults. Thorndike says, "Let the reader consider that if he should now spend seven hours, well distributed, in mental multiplication with three place numbers, he would thereby much more than double his speed and also reduce his errors; or that, by forty hours of practice, he could come to typewrite (supposing him to now have had zero practice) approximately as fast as he can write by hand; or that, starting from zero knowledge, he could learn to copy English into German script at a rate of fifty letters per minute, in three hours or a little more."[3] It is probably true that the majority of adults are much below their limit of efficiency in most of the habits required by their profession, and that in school habits the same thing is true of children. Spurious levels of accomplishment have been held up as worthy goals, and efficiency accepted as ultimate which was only two thirds, and often less than that, of what was possible. Of course it may not be worth the time and energy necessary to obtain improvement in certain lines,--that must be determined by the particular case,--but the point is, that improvement; is possible with both children and adults in almost every habit they possess with comparatively little practice. Neither the physiological limit of a function nor the age limit of the individual is reached as easily or as soon as has been believed.
There are certain aids to improvement which must be used in order that the best results may be obtained. Some of them have already been discussed and others will be discussed at a later time, so they need only be listed here, the right physiological conditions, the proper distribution of the practice periods, interest in the work, interest in improvement, problem attitude, attention, and absence of both excitement and worry.
Habits have been treated in psychology as wholes, just as if each habit was a unit. This has been true, whether the habits being discussed were moral habits, such as sharing toys with a younger brother; intellectual habits, such as reading and understanding the meaning of the word "and"; or motor habits, such as sitting straight. The slightest consideration of these habits makes obvious that they differ tremendously in complexity. The moral habit quoted involves both intellectual and motor habits--and not one, but several. From a physiological point of view, this difference in the complexity of habits is made clear by an examination of the number of neural bonds used in getting the habit response to a given situation. In some cases they are comparatively few--in others the number necessary is astonishing. In no case of habit will the bonds used involve but a single connection.
Just what bonds are needed in order that a child may learn to add, or to spell, to appreciate music, or to be industrious, is a question that only experiment and investigation can answer. At present but little is known as to just what happens, just what connections are formed, when from the original tendency towards vocalization the child just learns to say the word "milk," later reads it, and still later writes it. One thing is certain, the process is not a unitary one, nor is it a simple one. Just so long as habit is discussed in general terms, without any recognition of the complexity of the process or to the specific bonds involved, just so long will the process of habit formation be wasteful and inefficient.
As a sample of the kind of work being done in connection with special habits, investigation seems to give evidence that in the habit of simple column addition eight or nine distinct functions are involved, each of which involves the use of several bonds. Besides these positive connections, a child in learning must inhibit other connections which are incorrect, and these must often outnumber the correct ones. And yet column addition has always been treated as a simple habit--with perhaps one element of complexity, when carrying was involved. It is evident that, if the habit concerned does involve eight or nine different functions, a child might go astray in any one. His difficulty in forming the habit might be in connection with one or several of the processes involved. Knowledge on the part of the teacher of these different steps in the habit, and appreciation by him of the possibilities of making errors, are the prerequisites of efficient teaching of habits.
In each one of the subjects there is much need of definite experimental work, in order that the specific bonds necessary in forming the habits peculiar to the subject be determined. The psychology of arithmetic, or of physics, or of spelling should involve such information. Meanwhile every teacher can do much if she will carefully stop and think just what she is requiring in the given response. An analysis of the particular situation and response will make clear at least some of the largest elements involved, some of the most important connections to be made. It is the specific nature of the connections to be made and the number of those connections that need emphasis in the teaching of habits. Not only must the specific nature of the bonds involved in individual habits be stressed, but also the specific nature of the entire complex which is called the habit. There is no such thing as a general curve of learning that will apply equally well, no matter what the habit. The kind of curve, the rate of improvement, the possibilities of plateaus, the permanence of the improvement, all these facts and others vary with the particular habit.
In habit formation, as is the case in other types of activity, we get the most satisfactory results only when we secure a maximum of interest in the work to be done. The teacher who thinks that she can get satisfactory results merely by compelling children to repeat over and over again the particular form to be mastered is doomed to disappointment. Indeed, it is not infrequently true that the dislike which children get for the dreary exercises which have little or no meaning for them interferes to such a degree with the formation of the habit we hope to secure as to develop a maximum of inaccuracies rather than any considerable improvement. The teacher who makes a game out of her word drill in beginning reading may confidently expect to have children recognize more words the next day than one who has used the same amount of time, without introducing the motive which has made children enjoy their work. Children who compare their handwriting with a scale, which enables them to tell what degree of improvement they have made over a given period, are much more apt to improve than are children who are merely asked to fill up sheets of paper with practice writing. A vocabulary in a modern language will be built up more certainly if students seek to make a record in the mastery of some hundreds or thousands of words during a given period, rather than merely to do the work which is assigned from day to day. A group of boys in a continuation school have little difficulty in mastering the habits which are required in order to handle the formal processes in arithmetic, or to apply the formula of algebra or trigonometry, if the application of these habitual responses to their everyday work has been made clear. Wherever we seek to secure an habitual response we should attempt to have children understand the use to which the given response is to be put, or, if this is not possible, to introduce some extraneous motive which will give satisfaction.
We cannot be too careful in the habits which we seek to have children form to see to it that the first response is correct. It is well on many occasions, if we have any doubt as to the knowledge of children, to anticipate the response which they should give, and to make them acquainted with it, rather than to allow them to engage in random guessing. The boy who in writing his composition wishes to use a word which he does not know how to spell, should feel entirely free to ask the teacher for the correct spelling, unless there is a dictionary at hand which he knows how to use. It is very much better for a boy to ask for a particular form in a foreign language, or to refer to his grammar, than it is for him to use in his oral or written composition a form concerning which he is not certain. A mistake made in a formula in algebra, or in physics, may persist, even after many repetitions might seem to have rendered the correct form entirely automatic.
In matters of habit it does not pay to take it for granted that all have mastered the particular forms which have supposedly been taught, and it never pays to attempt to present too much at any one time. More satisfactory work in habit formation would commonly be done were we to teach fewer words in any one spelling lesson, or attempt to fix fewer combinations in any particular drill lesson in arithmetic, or assign a part of a declension or conjugation in a foreign language, or to be absolutely certain that one or two formulas were fixed in algebra or in chemistry, rather than in attempting to master several on the same day. Teachers ought constantly to ask themselves whether every member of the class is absolutely sure and absolutely accurate in his response before attempting new work. It is of the utmost importance that particular difficulties be analyzed, and that attention be fixed upon that which is new, or that which presents some unusual difficulty.
As has already been implied, it is important not simply to start with as strong a motive as possible, but it is also necessary to keep attention concentrated during the exercises which are supposed to result in habit formation. However strong the motive for the particular work may have been at the beginning, it is likely after a few minutes to lack power, if the particular exercise is continued in exactly the same form. Much is to be gained by varying the procedure. Oral work alternated with written work, concert work alternated with individual testing, the setting of one group over against another, the attempt to see how much can be done in a given period of minutes,--indeed, any device which will keep attention fixed is to be most eagerly sought for. In all practice it is important that the pupil strive to do his very best. If the ideal of accuracy or of perfection in form is once lost sight of, the responses given may result in an actual loss rather than in gain in fixing the habit. When a teacher is no longer able to secure attention to the work in hand, it is better to stop rather than to continue in order to provide for a given number of repetitions. Drill periods of from five to fifteen minutes two or three times a day may almost always be found to produce better results than the same amount of time used consecutively. Systematic reviews are most essential in the process of habit formation. The complaint of a fifth-grade teacher that the work in long division was not properly taught in the fourth grade may be due in considerable measure to the fact that she has neglected at the beginning of the fifth grade's work to spend a week or two in careful or systematic review of the work covered in the previous year. The complaint of high school teachers that children are not properly taught in the elementary school would often be obviated if in each of the fields in question some systematic review were given from time to time, especially at the beginning of the work undertaken, in any particular subject which involves work previously done in the elementary school. During any year's work that teacher will be most successful who reviews each day the work of the day before, who reviews each third or fourth day the particularly difficult parts of the work done during the previous periods, who reviews each week and each month, and even each two or three months, the work which has been covered up to that time. When teachers understand that the intervals between repetitions which seem to have fixed a habit may only be gradually lengthened, then will the formation of habits upon the part of boys and girls become more certain, and the difficulties arising from lapses and inaccuracies become less frequent.
As has been suggested in previous discussions, it will be necessary in habit formation to vary the requirements among the individuals who compose a group. The motive which we seek to utilize may make a greater appeal to one child than to another. Physiological differences may account for the fact that a small number of repetitions will serve to fix the response for one individual as over against a very much larger number of repetitions required for another. It is of the utmost importance that all children work up to the maximum of their capacity. It is very much better, for example, to excuse a boy entirely from a given drill exercise than to have him dawdle or loaf during the period. In some fields a degree of efficiency may be reached which will permit the most efficient children to be relieved entirely from certain exercises in order that they may spend their time on other work. On the other hand, those who are less capable may need to have special drill exercises arranged which will help them to make up their deficiency. The teacher who is acquainted with the psychology of habit formation should secure from the pupils in her class a degree of efficiency which is not commonly found in our schools.
