There is no Royal Road to Memory. The cultivation of the memory depends upon the practice along certain scientific lines according to well established psychological laws. Those who hope for a sure "short cut" will be disappointed, for none such exists. As Halleck says: "The student ought not to be disappointed to find that memory is no exception to the rule of improvement by proper methodical and long continued exercise. There is no royal road, no short cut, to the improvement of either mind or muscle. But the student who follows the rules which psychology has laid down may know that he is walking in the shortest path, and not wandering aimlessly about. Using these rules, he will advance much faster than those without chart, compass, or pilot. He will find mnemonics of extremely limited use. Improvement comes by orderly steps. Methods that dazzle at first sight never give solid results." The student is urged to pay attention to what we have to say in other chapters of the book upon the subjects of attention and association. It is not necessary to state here the particulars that we mention there. The cultivation of the attention is a prerequisite for good memory, and deficiency in this respect means deficiency not only in the field of memory but also in the general field of mental work. In all branches of The New Psychology there is found a constant repetition of the injunction to cultivate the faculty of attention and concentration. Halleck says: "Haziness of perception lies at the root of many a bad memory. If perception is definite, the first step has been taken toward insuring a good memory. If the first impression is vivid, its effect upon the brain cells is more lasting. All persons ought to practice their visualizing power. This will react upon perception and make it more definite. Visualizing will also form a brain habit of remembering things pictorially, and hence more exactly."
