The statement that our impression of movement does not result simply from the seeing of successive stages but includes a higher mental act into which the successive visual impressions enter merely as factors is in itself not really an explanation. We have not settled by it the nature of that higher central process. But it is enough for us to see that the impression of the continuity of the motion results from a complex mental process by which the various pictures are held together in the unity of a higher act. Nothing can characterize the situation more clearly than the fact which has been demonstrated by many experiments, namely, that this feeling of movement is in no way interfered with by the distinct consciousness that important phases of the movement are lacking. On the contrary, under certain circumstances we become still more fully aware of this apparent motion created by our inner activity when we are conscious of the interruptions between the various phases of movement.
We come to the consequences. What is then the difference between seeing motion in the photoplay and seeing it on the real stage? There on the stage where the actors move the eye really receives a continuous series. Each position goes over into the next without any interruption. The spectator receives everything from without and the whole movement which he sees is actually going on in the world of space without and accordingly in his eye. But if he faces the film world, the motion which he sees appears to be a true motion, and yet is created by his own mind. The afterimages of the successive pictures are not sufficient to produce a substitute for the continuous outer stimulation; the essential condition is rather the inner mental activity which unites the separate phases in the idea of connected action. Thus we have reached the exact counterpart of our results when we analyzed the perception of depth. We see actual depth in the pictures, and yet we are every instant aware that it is not real depth and that the persons are not really plastic. It is only a suggestion of depth, a depth created by our own activity, but not actually seen, because essential conditions for the true perception of depth are lacking. Now we find that the movement too is perceived but that the eye does not receive the impressions of true movement. It is only a suggestion of movement, and the idea of motion is to a high degree the product of our own reaction. Depth and movement alike come to us in the moving picture world, not as hard facts but as a mixture of fact and symbol. They are present and yet they are not in the things. We invest the impressions with them. The theater has both depth and motion, without any subjective help; the screen has them and yet lacks them. We see things distant and moving, but we furnish to them more than we receive; we create the depth and the continuity through our mental mechanism.

Table of Contents ATTENTION
Table of Contents The mere perception of the men and women and of the background, with all their depth and their motion, furnishes only the material. The scene which keeps our interest alive certainly involves much more than the simple impression of moving and distant objects. We must accompany those sights with a wealth of ideas. They must have a meaning for us, they must be enriched by our own imagination, they must awaken the remnants of earlier experiences, they must stir up our feelings and emotions, they must play on our suggestibility, they must start ideas and thoughts, they must be linked in our mind with the continuous chain of the play, and they must draw our attention constantly to the important and essential element of the action. An abundance of such inner processes must meet the world of impressions and the psychological analysis has only started when perception of depth and movement alone are considered. If we hear Chinese, we perceive the sounds, but there is no inner response to the words; they are meaningless and dead for us; we have no interest in them. If we hear the same thoughts expressed in our mother tongue, every syllable carries its meaning and message. Then we are readily inclined to fancy that this additional significance which belongs to the familiar language and which is absent from the foreign one is something which comes to us in the perception itself as if the meaning too were passing through the channels of our ears. But psychologically the meaning is ours. In learning the language we have learned to add associations and reactions of our own to the sounds which we perceive. It is not different with the optical perceptions. The best does not come from without.
Of all internal functions which create the meaning of the world around us, the most central is the attention. The chaos of the surrounding impressions is organized into a real cosmos of experience by our selection of that which is significant and of consequence. This is true for life and stage alike. Our attention must be drawn now here, now there, if we want to bind together that which is scattered in the space before us. Everything must be shaded by attention and inattention. Whatever is focused by our attention wins emphasis and irradiates meaning over the course of events. In practical life we discriminate between voluntary and involuntary attention. We call it voluntary if we approach the impressions with an idea in our mind as to what we want to focus our attention on. We carry our personal interest, our own idea into the observation of the objects. Our attention has chosen its aim beforehand, and we ignore all that does not fulfil this specific interest. All our working is controlled by such voluntary attention. We have the idea of the goal which we want to reach in our mind beforehand and subordinate all which we meet to this selective energy. Through our voluntary attention we seek something and accept the offering of the surroundings only in so far as it brings us what we are seeking.
It is quite different with the involuntary attention. The guiding influence here comes from without. The cue for the focusing of our attention lies in the events which we perceive. What is loud and shining and unusual attracts our involuntary attention. We must turn our mind to a place where an explosion occurs, we must read the glaring electric signs which flash up. To be sure, the perceptions which force themselves on our involuntary attention may get their motive power from our own reactions. Everything which appeals to our natural instincts, everything which stirs up hope or fear, enthusiasm or indignation, or any strong emotional excitement will get control of our attention. But in spite of this circuit through our emotional responses the starting point lies without and our attention is accordingly of the involuntary type. In our daily activity voluntary and involuntary attention are always intertwined. Our life is a great compromise between that which our voluntary attention aims at and that which the aims of the surrounding world force on our involuntary attention.
How does the theater performance differ in this respect from life? Might we not say that voluntary attention is eliminated from the sphere of art and that the audience is necessarily following the lead of an attention which receives all its cues from the work of art itself and which therefore acts involuntarily? To be sure, we may approach a theater performance with a voluntary purpose of our own. For instance, we may be interested in a particular actor and may watch him with our opera glass all the time whenever he is on the stage, even in scenes in which his rôle is insignificant and in which the artistic interest ought to belong to the other actors. But such voluntary selection has evidently nothing to do with the theater performance as such. By such behavior we break the spell in which the artistic drama ought to hold us. We disregard the real shadings of the play and by mere personal side interests put emphasis where it does not belong. If we really enter into the spirit of the play, our attention is constantly drawn in accordance with the intentions of the producers.
Surely the theater has no lack of means to draw this involuntary attention to any important point. To begin with, the actor who speaks holds our attention more strongly than the actors who at that time are silent. Yet the contents of the words may direct our interest to anybody else on the stage. We watch him whom the words accuse, or betray or delight. But the mere interest springing from words cannot in the least explain that constantly shifting action of our involuntary attention during a theater performance. The movements of the actors are essential. The pantomime without words can take the place of the drama and still appeal to us with overwhelming power. The actor who comes to the foreground of the stage is at once in the foreground of our consciousness. He who lifts his arm while the others stand quiet has gained our attention. Above all, every gesture, every play of the features, brings order and rhythm into the manifoldness of the impressions and organizes them for our mind. Again, the quick action, the unusual action, the repeated action, the unexpected action, the action with strong outer effect, will force itself on our mind and unbalance the mental equilibrium.
The question arises: how does the photoplay secure the needed shifting of attention? Here, too, involuntary attention alone can be expected. An attention which undertakes its explorations guided by preconceived ideas instead of yielding to the demands of the play would lack adjustment to its task. We might...
