=Aids Morality.=--The formation of habits also has an important bearing on the moral life. By habituating ourselves to right forms of action, we no doubt make in a sense moral machines of ourselves, since the right action is the one that will meet the least nervous resistance, while the doing of the wrong action would necessitate the establishing of new co-ordinations in the nervous system. It is no doubt partly owing to this, that one whose habits are formed can so easily resist temptations; for to ask him to act other than in the old way is to ask him to make, not the easy, but the hard reaction. While this is true, however, it must not be supposed that in such cases the choice of the right thing involves only a question of customary nervous reaction. When we choose to do our duty, we make a conscious choice, and although earlier right action has set up certain nerve co-ordinations which render it now easy to choose the right, yet it must be remembered that _conscious judgment_ is also involved. In such cases man does the right mainly because his judgment tells him that it is right. If, therefore, he is in a situation where he must act in a totally different way from what is customary, as when a quiet, peace-loving man sees a ruffian a.s.saulting a helpless person, a moral man does not hesitate to change his habitual modes of physical action.

IMPROVEMENT OF HABITUAL REACTIONS

=To Eliminate a Habit.=--From what has been learned concerning the permanency of our habits, it is evident that only special effort will enable us to make any change in an habitual mode of reaction. In at least two cases, however, changes may be necessary. The fact that many of our early habits are formed either unconsciously, or in ignorance of their evil character, finds us, perhaps, as we come to years of discretion, in possession of certain habits from which we would gladly be freed. Such habits may range from relatively unimportant personal peculiarities to impolite and even immoral modes of conduct. In attempting to free ourselves from such acts, we must bear in mind what has been noted concerning the basis of retention. To repeat an act at frequent intervals is an important condition of retaining it as a habit.

On the other hand, the absence of such repet.i.tion is almost sure, in due time, to obliterate the nervous tendency to repeat the act. To free one"s self from an undesirable habit, therefore, the great essential is to avoid resolutely, for a reasonable time, any recurrence of the banned habit. While this can be accomplished only by conscious effort and watchfulness, yet each day pa.s.sed without the repet.i.tion of the act weakens by so much the old nerve co-ordinations. To attempt to break an old habit, gradually, however, as some would prefer, can result only in still keeping the habitual tendency relatively strong.

=To Modify a Habit.=--At other times, however, we may desire not to eliminate an habitual co-ordination _in toto_, but rather to modify only certain phases of the reaction. In writing, for instance, a pupil may be holding his pen correctly and also using the proper muscular movements, but may have developed a habit of forming certain letters incorrectly, as [symbol] and [symbol]. In any attempt to correct such forms, a special difficulty is met in the fact that the incorrect movements are now closely co-ordinated with a number of correct movements, which must necessarily be retained while the other portions of the process are being modified. To effect such a modification, it is necessary for attention to focus itself upon the incorrect elements, and form a clear idea of the changes desired. With this idea as a conscious aim, the pupil must have abundant practice in writing the new forms, and avoid any recurrence of the old incorrect movements. This fact emphasizes the importance of attending to the beginning of any habit. In teaching writing, for instance, the teacher might first give attention only to the form of the letter and then later seek to have the child acquire the muscular movement. In the meantime, however, the child, while learning to form the letters, may have been allowed to acquire the finger movement, and to break this habit both teacher and pupil find much difficulty. By limiting the child to the use of a black-board or a large pencil and tablet, and having him make only relatively large letters while he is learning to form them, the teacher could have the pupil avoid this early formation of the habit of writing with the finger movement.

=Limitations of Habit.=--From what has here been learned concerning the formation of physical habits, it becomes evident that there are limitations to these as forms of reaction. Since any habit is largely an unconscious reaction to a particular situation, its value will be conditional upon the nature of the circ.u.mstances which call forth the reaction. These circ.u.mstances must occur quite often under almost identical conditions, otherwise the habit can have no value in directing our social conduct. On the contrary, it may seriously interfere with successful effort. For the player to habituate his hands to fingering the violin is very important, because this is a case where such constant conditions are to be met. For a salesman to habituate himself to one mode of presenting goods to his customers would be fatal, since both the character and the needs of the customers are so varied that no permanent form of approach could be effective in all cases. To habituate ourselves to some narrow automatic line of action and follow it even under varying circ.u.mstances, therefore, might prevent the mind from properly weighing these varying conditions, and thus deaden initiative. It is for this reason that experience is so valuable in directing life action. By the use of past experience, the mind is able to a.n.a.lyse each situation calling for reaction and, by noting any unusual circ.u.mstances it presents, may adapt even our habitual reactions to the particular conditions.

The relation of habit to interest and attention is treated in Chapter XXIV.

CHAPTER XXIII

ATTENTION

=Nature of Attention.=--In our study of the principles of general method, it was noted that the mind is able to set up and hold before itself as a problem any partially realized experience. From what has been said concerning nervous stimulation and the pa.s.sing inward of sensuous impression, it might be thought that the mind is for the most part a somewhat pa.s.sive recipient of conscious states as they chance to arise through the stimulations of the particular moment. Further consideration will show, however, that, at least after very early childhood, the mind usually exercises a strong selective control over what shall occupy consciousness at any particular time. In the case of a student striving to unravel the mazes of his mathematical problem, countless impressions of sight, sound, touch, etc., may be stimulating him from all sides, yet he refuses in a sense to attend to any of them.

The singing of the maid, the chilliness of the room as the fire dies out, even the pain in the limb, all fail to make themselves known in consciousness, until such time as the successful solution causes the person to direct his attention from the work in hand. In like manner, the traveller at the busy station, when intent upon catching his train, is perhaps totally unconscious of the impressions being received from the pa.s.sing throngs, the calling newsboys, the shunting engines, and the malodorous cattle cars. This ability of the mind to focus itself upon certain experiences to the exclusion of other possible experiences is known as _attention_.

=Degree of Attention.=--Mention has already been made of states of consciousness in which the mind seems in a pa.s.sive state of reverie.

Although the mind, even in such sub-conscious states, would seem to exercise some slight attention, it is yet evident that it does not exercise a definite selective control during such pa.s.sive states of consciousness. Attention proper, on the other hand, may be described as a state in which the mind focuses itself upon some particular impression, and thus makes it stand out more clearly in consciousness as a definite experience. From this standpoint it may be a.s.sumed that, in a state of waking reverie, the attention is so scattered that no impression is made to stand out clearly in consciousness. On the other hand, as soon as the mind focuses itself on a certain impression, for example, the report of a gun, the relation of two angles, or the image of a centaur, this stands out so clearly that it occupies the whole foreground of consciousness, while all other impressions hide themselves in the background. This single focal state of consciousness is, therefore, pre-eminently a state of attention while the former state of reverie, on account of its diffuse character, may be said to be relatively devoid of attention.

=Physical Ill.u.s.trations of Attention.=--To furnish a physical ill.u.s.tration of the working of attention, some writers describe the stream of our conscious life as presenting a series of waves, the successive waves representing the impressions or ideas upon which attention is focused at successive moments. When attention is in a diffuse state, consciousness is likened to a comparatively level stream.

The focusing of attention upon particular impressions and thus making them stand out as distinct states of consciousness is said to break the surface of the stream into waves. This may be ill.u.s.trated as follows:

[Ill.u.s.tration: FIG. 1--Consciousness in a state of pa.s.sive reverie.

FIG. 2--Active consciousness. Attention focussed on the definite experiences _a, b, c, d, e, f, g_.]

By others, consciousness is described as a field of vision, in which the centre of vision represents the focal point of attention. For instance, if the student intent upon his problem in a.n.a.lysis does not notice the flickering light, the playing of the piano, or the smell of the burning meat breaking in upon him, it is because this problem occupies the centre of the attentive field. The other impressions, on the contrary, lie so far on the outside of the field that they fail to stand out in consciousness. This may be represented by the following diagram:

[Ill.u.s.tration: P represents the problem on which attention is fixed. A, B, C, D, E, represent impressions which, though stimulating the organism, do not attract definite attention.]

It must be understood, however, that these are merely mechanical devices to ill.u.s.trate the fact that when the mind selects, or attends to, any impression, this impression is made to stand out clearly as an object in consciousness; or, in other words, the particular impression becomes a clear-cut and definite experience.

[Ill.u.s.tration: Probable adjusting of nerve ends during active attention]

=Neural Basis of Attention.=--The neural conditions under which the mind exercises such active attention seem to be that during the attentive state the nervous energy concentrates itself upon the paths and centres involved in the particular experience, the resistance being decreased in the paths connecting the cells traversed by the impulse. Moreover, any nervous energy tending to escape in other channels is checked and the movements hindered, thus shutting off attention from other possible experiences. For instance, a person with little interest in horticulture might pa.s.s a flowering shrub, the colour, form, and scent making only a faint impression upon him. If, however, his companion should say, "What a lovely colour," his attention will direct itself to this quality, with the result that the colour stands out much more clearly in consciousness, and the other features practically escape his notice.

Here the suggestion of the companion focuses attention upon the colour, this being accompanied with a lessening of the resistance between the centres involved in interpreting the colour sensations. At the same time resistance in the arcs involving form and smell is increased, and the energy diverted from these arcs into that of colour.

ATTENTION SELECTIVE

=Attention and Interest.=--At this point a question naturally arises why the mind, since it is continually subject to the influence of impressions from without and of reviving ideas from within, should select and focus attention upon certain of these to the exclusion of others. The answer usually given is that the mind feels in each case, at least vaguely, a personal interest in some change or adjustment to be wrought either in or through the impression which it makes an object of attention. When, for instance, the reader diverts his attention from the interesting story to the loud talking outside the window, he evidently desires to adjust his understanding more fully to the new and strange impression. So, also, when the spectator rivets his attention upon the flying ball, it is because he a.s.sociates with this the interesting possibility of a change in the score. In like manner, the student in geometry fixes his attention upon the line joining the points of bisection of the sides, because he desires to change his present mental state of uncertainty as to its parallelism with the base into one of certainty. He further fixes his attention upon the qualities of certain bases and triangles, because through attending to these, he hopes to gain the desired experience concerning the parallelism of the two lines.

=Attention and the Question.=--The general conditions for determining the course of attention will be further understood by a reference to two facts already established in connection with general method. It has been seen that the question and answer method is usually a successful mode of conducting the learning process. The reason for this is that the question is a most effective means of directing a selective act of attention. For instance, in an elementary science lesson on the candle flame, although the child, if left to himself, might observe the flame, he would not, in all probability, notice particularly the luminous part.

Or again, if a dry gla.s.s is simply held over the flame and then removed by the demonstrator, although the pupil may have watched the experiment in a general way, it is doubtful whether he would notice particularly the moisture deposited upon the gla.s.s. A question from the demonstrator, however, awakens interest, causes the mind to focus in a special direction, and banishes from consciousness features which might otherwise occupy attention. This is because the question suggests a problem, and thus awakens an expectant or unsatisfied state of mind, which is likely to be satisfied only by attending to what the question suggests as an object of attention.

=Attention and Motive.=--It has already been noted that any process of learning is likely to be more effective when the child realizes a distinct problem, or aim, in the lesson, or feels a need for going through the learning process. The cause of this is that the aim, by awaking curiosity, etc., is an effective means of securing attention.

When, for example, the pupil, in learning that 3 4 = 12, begins with the problem of finding out how many threes are contained in his twelve blocks, his curiosity can be satisfied only by grasping certain significant relations. In approaching the lesson, therefore, with such an actual problem before him, the child feels a desire to change, or alter, his present mental relation to the problem. In other words, he wishes to gain something involved in the problem which he does not now know or is not yet able to do. His desire to bring about this change or to reach this end not only holds his attention upon the problem, but also adjusts it to whatever ideas are likely to a.s.sist in solving the problem. When, therefore, pupils approach a lesson with an interesting problem in mind, the teacher finds it much easier to centre their attention upon those factors which make for the acquisition of the new experience.

INVOLUNTARY ATTENTION

=Nature of Involuntary Attention.=--Attention is met in its simplest form when the mind spontaneously focuses itself upon any strong stimulus received through the senses, as a flashing light, a loud crash, a bitter taste, or a violent pressure. As already noted, the significance of this type of attention lies in the fact that the mind seeks to adjust itself intelligently to a new condition in its surroundings which has been suggested to it through the violent stimulus. The ability to attend to such stimuli is evidently an inherited capacity, and is possessed by animals as well as by children. It is also the only form of attention exercised by very young children, and for some time the child seems to have little choice but to attend to the ever varying stimuli, the attention being drawn now to a bright light, now to a loud voice, according to the violence of the impressions. On account of the apparent lack of control over the direction of attention, this type is spoken of as spontaneous, or involuntary, attention.

=Place and Value.=--It is only, however, during his very early years that man lacks a reasonable control even over relatively strong stimulations. As noted above, the mind acquires an ability to concentrate itself upon a single problem in the midst of relatively violent stimulations. Moreover, in the midst of various strong stimulations, it is able to select the one which it desires, to the exclusion of all others. At a relatively early age, for instance, the youth is able, in his games, to focus his attention upon the ball, and pays little attention to the shouts and movements of the spectators. On the other hand, however, it is also true that man never loses this characteristic of attending in an involuntary, or reflex, way to any strong stimulus. Indeed, without the possession of this hereditary tendency, it is hard to see how he could escape any dangers with which his body might be threatened while his attention is strongly engaged an another problem.

=Educational Precautions.=--That young children naturally tend to give their attention to strong stimuli, is a matter of considerable moment to the primary teacher. It is for this cause, among others, that reasonable quiet and order should prevail in the cla.s.s-room during the recitation.

When the pupil is endeavouring to fix his attention upon a selected problem, say the relation of the square foot to the square yard, any undue stimulation of his senses from the school-room environment could not fail to distract his attention from the problem before him. For the same reason, the external conditions should be such as are not likely to furnish unusual stimulations, as will be the case if the cla.s.s-room is on a busy street and must be ventilated by means of open windows.

Finally, in the use of ill.u.s.trative materials, the teacher should see that the concrete matter will not stimulate the child unduly in ways foreign to the lesson topic. For example, in teaching a nature lesson on the crow, the teacher would find great difficulty in keeping the children"s attention on the various topics of the lesson, if he had before the cla.s.s a live crow that kept cawing throughout the whole lesson period. Nor would it seem a very effective method of attracting attention to the problem of a lesson, if the teacher were continually shouting and waving his arms at the pupils.

NON-VOLUNTARY ATTENTION

=Nature of Non-voluntary Attention.=--On account of the part played by interest in the focusing of attention, it is possible to distinguish a second type of spontaneous attention in which the mind seems directly attracted to an object of thought because of a natural satisfaction gained from contemplating the subject. The lover, apparently without any determination, and without any external stimulus to suggest the topic, finds his attention ever centring itself upon the image of his fair lady. The young lad, also, without any apparent cause, turns his thoughts constantly to his favourite game. Here the impulse to attend is evidently from within, rather than from without, and arises from the interest that the mind has in the particular experience. This type of attention is especially manifest when trains of ideas pa.s.s through the mind without any apparent end in view, one idea suggesting another in accordance with the prevailing mood. The mind, in a half pa.s.sive state, thinks of last evening, then of the house of a friend, then of the persons met there, then of the game played, etc. In the same way the attention of the student turns without effort to his favourite school subject, and its various aspects may pa.s.s in view before him without any effort or determination on his part. Because in this type of attention the different thoughts stand out in consciousness without any apparent choice, or selection, on the part of the mind, it is described as non-voluntary attention.

VOLUNTARY ATTENTION

=Nature of Voluntary Attention.=--The most important form of attention, however, is that in which the mind focuses itself upon an idea, not as a result of outside stimulation, but with some further purpose in view.

For instance, when a person enters a room in which a strange object seems to be giving out musical notes automatically, he may at first give spontaneous attention to the sounds coming from the instrument. When, however, he approaches the object later with a desire to discover the nature of its mechanism, his attention is focused upon the object with a more remote aim, or end, in view, to discover where the music comes from. So also, when the lad mentioned in Chapter II fixed his attention on the lost coin, he set this object before his attention with a further end in view--how to regain it. Because the person here _determines_ to attend to, or think about, a certain problem, in order that he may reach a certain consciously set end, this form of attention is described as voluntary, or active, attention.

=Near and Remote Ends.=--It is to be noted, however, that the interesting end toward which the mind strives in voluntary attention may be relatively near or remote. A child examining an automatic toy does it for the sake of discovering what is in the toy itself; an adult in order to see whether it is likely to interest his child. A student gives attention to the problem of the length of the hypotenuse because he is interested in the mathematical problem itself, the contractor because he desires to know how much material will be necessary for the roof of the building. One child may apply himself to mastering a reading lesson because the subject itself is interesting to him, another because he desires to take home a perfect report at the end of the week, and a third because a sense of obligation tells him that teacher and parents will expect him to study it.

=How we Attend to a Problem.=--Since voluntary attention implies mental movement directed to the attainment of some end, the mind does not simply keep itself focused on the particular problem. For instance, in attempting to solve the problem that the exterior angle of a triangle equals the sum of the two interior and opposite angles, no progress toward the attainment of the end in view could be made by merely holding before the mind the idea of their equality. It is, in fact, impossible for the attention to be held for any length of time on a single topic.

This will be readily seen if one tries to hold his attention continuously upon, say, the tip of a pencil. When this is attempted, other ideas constantly crowd out the selected idea. The only sense, therefore, in which one holds his attention upon the problem in an act of voluntary attention is, that his attention pa.s.ses forward and back between the problem and ideas felt to be a.s.sociated with it. Voluntary attention is, therefore, a mental process in which the mind shifts from one idea to another in attaining to a desired end, or problem. In this shifting, or movement, of voluntary attention, however, two significant features manifest themselves. First, in working forward and back from the problem as a controlling centre, attention brings into consciousness ideas more or less relevant to the problem. Secondly, it selects and adjusts to the problem those that actually make for its solution, and banishes from consciousness whatever is felt to be foreign to obtaining the desired end.

=Example of Controlled Attention.=--To exemplify a process of voluntary attention we may notice the action of the mind in solving such a problem as:

Two trains started at the same moment from Toronto and Hamilton respectively, one going at the rate of thirty miles an hour and the other at the rate of forty miles an hour. Supposing the distance between Toronto and Hamilton to be forty miles, in how many minutes will the trains meet?

Here the pupil must first fix his attention upon the problem--the number of minutes before the trains will meet. This at once forms both a centre and a standard for measuring other related ideas. In this way his attention pa.s.ses to the respective rates of the two trains, thirty and forty miles per hour. Then perhaps he fixes attention on the thought that one goes a mile in two minutes and the other a mile in 1-1/2 minutes. But as he recognizes that this is leading him away from the problem, resistance is offered to the flow of attention in this direction, and he pa.s.ses to the thought that in a _minute_ the former goes 1/2 mile and the later 2/3 of a mile. From this he pa.s.ses to the thought that in one minute they together go 1-1/6 miles. Hereupon perhaps the idea comes to his mind to see how many miles they would go in an hour. This, however, is soon felt to be foreign to the problem, and resistance being set up in this direction, the attention turns to consider in what time the two together cover 40 miles. Now by dividing 40 miles by 1-1/6, he obtains the number 34-2/7 and is satisfied that his answer is 34-2/7 minutes. The process by which the attention here selected and adjusted the proper ideas to the problem might be ill.u.s.trated by the following Figure:

[Ill.u.s.tration]

Here "P" represents the problem; a, b, c, d, and e, ideas accepted as relevant to the problem; and b", d" ideas suggested by b and d, but rejected as not adjustable to the problem.

=Factors in Process.=--The above facts demonstrate, however, that the mind can take this att.i.tude toward any problem only if it has a certain store of old knowledge relative to it. Two important conditions of voluntary attention are therefore, first, that the mind should have the necessary ideas, or knowledge, with which to attend and, secondly, that it would select and adjust these to the purpose in view. Here the intimate connection of voluntary attention to the normal learning process is apparent. The step of preparation, for instance, is merely putting the mind in the proper att.i.tude to attend voluntarily to an end in view, namely the lesson problem; while the so-called a.n.a.lytic-synthetic process of learning involves the selecting and adjusting movements of voluntary attention.

=Spontaneous and Voluntary Attention Distinguished.=--In describing voluntary attention as an active form of attention, psychologists a.s.sume that since the mind here wills, or resolves, to attend, in order to gain a certain end in view; therefore voluntary attention must imply a much greater degree of effort, or strain, than other types. That such is always the case, however, is at times not very apparent. If one may judge by the straining of eye or ear, the poise of the body, the holding of the breath, etc., when a person gives involuntary attention to any sudden impression, as a strange noise at night, it is evident that the difference of effort, or strain, in attending to this and some selected problem may not, during the time it continues, be very marked.

It is of course true that in voluntary attention the mind must choose its own object of attention as an end, or aim, while in the involuntary type the problem seems thrust upon us. This certainly does imply a deliberate choice in the former, and to that extent may be said to involve an effort not found in the latter. In like manner, when seeking to attain the end which has been set up, the mind must select the related ideas which will solve its problem. This in turn may demand the grasping of a number of complex relations. To say, however, that all striving to attain an end is lacking in a case of involuntary attention would evidently be fallacious. When the mind is startled by a strange noise, the mind evidently does go out, though in a less formal way, to interpret a problem involuntarily thrust upon it. When, for instance, we receive the violent impression, the mind may be said to ask itself, "What strange impression is this?" and to that extent, even here, faces a selected problem. The distinguishing feature of voluntary attention, therefore, is the presence of a consciously conceived end, or aim, upon which the mind deliberately sets its attention as something to be thought _about_.
