to act in it—how to act in all the various situations of life.

The third question—concerning the nature of the child—cannot be so briefly answered. In fact, it cannot be fully answered at the present time. We must know what the child’s original nature is. This means that we must know the instincts and all the other inherited capacities and tendencies. We must know the laws of building up habits and of acquiring knowledge, the laws of retention and the laws of attention. These problems constitute the subject matter of educational psychology, and at present can be only partially solved. We have, however, a very respectable body of knowledge in this field, though it is by no means complete.

The answer to the fourth question is in part dependent upon the progress in answering the third. Economical methods of training children must be dependent upon the nature of children. But in actual practice, we are trying to find out the best procedure of doing each single thing in school work; we are trying to find out by experimentation. The proper way to teach children to read, to spell, to write, etc., must be determined in each case by independent investigation, until our knowledge of the child becomes sufficient for us to infer from general laws of procedure what the procedure in a particular case should be. We venture to infer what ought to be done in some cases, but generally we feel insecure till we have proved our inference correct by trying out different methods and measuring the results.

Education will not be fully scientific till we have definite knowledge to guide us at every step. What should we teach? When should we teach it? How should we teach it? How poorly we answer these questions at the present time! How inefficient and uneconomical our schools, because we cannot fully answer them! But they are answerable. We can answer them in part now, and we know how to find out the answer in full. It is just a matter of patient and extensive investigation. We must say, then, that we have only the beginnings of a science of education. The problems which a science of education must solve are almost wholly psychological problems. They could not be solved till we had a science of psychology. Experimental psychology is but a half-century old; educational psychology, less than a quarter-century old. In the field of education, the science of psychology may expect to make its most important practical contribution. Let us, then, consider very briefly the problems of educational psychology.

Educational Psychology. Educational psychology is that division of psychology which undertakes to discover those aspects of human nature most closely related to education. These are (1) the original nature of the child—what it is and how it can be modified; (2) the problem of acquiring and organizing experience—habit-formation, memory, thinking, and the various factors related to these processes. There are many subordinate problems, such as the problem of individual differences and their bearing on the education of subnormal and supernormal children. Educational psychology is not, then, merely the application of psychology to education. It is a distinct science in itself, and its aim is the solving of those educational problems which for their solution depend upon a knowledge of the nature of the child.

The Method of Psychology. We have enumerated the various problems of psychology, now how are they solved? The method of psychology is the same as that of all other sciences; namely, the method of observation and experiment. We learn human nature by observing how human beings act in all the various circumstances of life. We learn about the human mind by observing our own mind. We learn that we see under certain objective conditions, hear under certain objective conditions, taste, smell, feel cold and warm under certain objective conditions. In the case of ourselves, we can know both our actions and our mind. In the case of others, we can know only their actions, and must infer their mental states from our own in similar circumstances. With certain restrictions and precautions this inference is legitimate.

We said the method of psychology is that of observation and experiment. The experiment is observation still, but observation subjected to exact methodical procedure. In a psychological experiment we set out to provide the necessary conditions, eliminating some and supplying others according to our object. The experiment has certain advantages. It enables us to isolate the phenomena to be studied, it enables us to vary the circumstances and conditions to suit our purposes, it enables us to repeat the observation as often as we like, and it enables us to measure exactly the factors of the phenomena studied.

A Psychological Experiment. Let us illustrate psychological method by a typical experiment. Suppose we wish to measure the individual differences among the members of a class with respect to a certain ability; namely, the muscular speed of the right hand. Psychological laboratories have delicate apparatus for making such a study. But let us see how we can do it, roughly at least, without any apparatus. Let each member of the class take a sheet of paper and a pencil, and make as many strokes as possible in a half-minute, as shown in Figure I. The instructor can keep the time with a stop watch, or less accurately with the second hand of an ordinary watch. Before beginning the experiment, the instructor should have each student taking the test try it for a second or two. This is to make sure that all understand what they are to do. When the instructor is sure that all understand, he should have the students hold their pencils in readiness above the paper, and at the signal, “Begin,” all should start at the same time and make as many marks as possible in the half-minute. The strokes can then be counted and the individual scores recorded. The experiment should be repeated several times, say six or eight, and the average score for each individual recorded.

Whether the result in such a performance as this varies from day to day, and is accidental, or whether it is constant and fundamental, can be determined by repeating the experiment from day to day. This repetition will also show whether improvement comes from practice.

If it is decided to repeat the experiment in order to study these factors, constancy and the effects of practice, some method of studying and interpreting the results must be found. Elaborate methods of doing this are known to psychologists, but the beginner must use a simpler method. When the experiment is performed for the first time, the students can be ranked with reference to their abilities, the fastest one being called “first,” the second highest, “second,” and so on down to the slowest performer. Then after the experiment has been performed the second time, the students can be again ranked.

A rough comparison can then be made as follows: Determine how many who were in the best half in the first experiment are among the best half in the second experiment. If most who were among the best half the first time are among the best half in the second experiment, constancy in this performance is indicated. Or we might determine how many change their ranks and how much they change. Suppose there are thirty in the class and only four improve their ranks and these to the extent of only two places each. This would indicate a high degree of constancy. Two different performances can be compared as above described. The abilities on successive days can be determined by taking the average rank of the first day and comparing it with the average rank of the second day.

If the effects of practice are to be studied, the experiments must be kept up for many days, and each student’s work on the first day compared with his work on succeeding days. Then a graph can be plotted to show the improvement from day to day. The average daily speed of the class can be taken and a graph made to show the improvement of the class as a whole. This might be plotted in black ink, then each individual student could put on his improvement in red ink, for comparison. A group of thirty may be considered as furnishing a fair average or norm in this kind of performance.

In connection with this simple performance, making marks as fast as possible, it is evident that many problems arise. It would take several months to solve anything like all of them. It might be interesting, for example, to determine whether one’s speed in writing is related to this simple speed in marking. Each member of the class might submit a plan for making such a study.

The foregoing simple study illustrates the procedure of psychology in all experimentation. A psychological experiment is an attempt to find out the truth in regard to some aspect of human nature. In finding out this truth, we must throw about the experiment all possible safeguards. Every source of error must be discovered and eliminated. In the above experiment, for example, the work must be done at the same time of day, or else we must prove that doing it at different times of day makes no difference. Nothing must be taken for granted, and nothing must be assumed. Psychology, then, is like all the other sciences, in that its method of getting its facts is by observation and experiment.

Summary. Science is systematic, related knowledge. Each science has a particular field which it attempts to explore and describe. The field of psychology is the study of sensitivity, action, and consciousness, or briefly, human behavior. Its main problems are development, heredity, instincts, habits, sensation, memory, thinking, and individual differences. Its method is observation and experiment, the same as in all other sciences.

DEVELOPMENT OF THE RACE AND OF THE INDIVIDUAL

Racial Development. The purpose of this chapter is to make some inquiry concerning the origin of the race and of the individual. In doing this, it is necessary for us first of all to fix in our minds the idea of causality. According to the view of all modern science, everything has a cause. Nothing is uncaused. One event is the result of other previous events, and is in turn the cause of other events that follow. Yesterday flowed into to-day, and to-day flows into to-morrow. The world as it exists to-day is the result of the world as it existed yesterday. This is true not only of the inorganic world—the world of physics
