Very interesting are the various ways in which the learner attacks a list of nonsense syllables, numbers, or disconnected words. He goes to work something like the cat trying to escape from a strange cage. He proceeds by a sort of trial and error observation; he keeps looking for something about the list that will help to fix it. He sees something that promises well for a moment, then gives it up because he sees something better. He notices positions, i.e., connects items with their position in the list. He finds syllables that stand out as peculiar in some way, being "odd", "fuzzy", smooth, agreeable, disagreeable, or resembling some word, abbreviation or nickname. He notes resemblances and contrasts between different syllables. He also finds groups that resemble each other, or that resemble words.
Besides what he actually finds in the list, he imports meanings, more or less far-fetched, into the list. He may make a rhythmical line of verse out of it; he may make a story out of it. In short, he both explores the list as it stands and manipulates it into some shape that promises to be rememberable.
His line of attack differs according to the particular test that is later to be made of his memory. Suppose he is shown a number of pictures, with the understanding that later those now shown are to be mixed with others, and that he must then pick out those now shown--then he simply examines each picture for something characteristic. But [{336}] suppose each picture is given a name, and he must later tell the name of each--then he seeks for something in the picture that can be made to suggest its name. Or suppose, once more, that the pictures are spread out before him in a row, and he is told that they will later be mixed and he be required to rearrange them in the same order in which they are now shown--then he seeks for relationships between the several pictures. His process of memorizing, always observant, exploratory and manipulatory, differs in detail according to the memory task that he expects later to perform.
For another example, suppose an experiment is conducted by the method of "paired associates". The subject is handed a list of pairs of words, such as
soprano emblem
grassy concise
nothing ginger
faraway kettle
shadow next
mercy scrub
hilltop internal
recite shoestring
narrative thunder
seldom harbor
jury eagle
windy occupy
squirm hobby
balloon multiply
necktie unlikely
supple westbound
obey inch
broken relish
spellbound ferment
desert expect
He must learn to respond with the second word of each pair when the first word of the pair is given. What he does, in learning this lesson, is to take each pair of words as a unit, and try to find something in the pair that shall make it a firm unit. It may be simply the peculiar sound or look of a pair that he notes, or it may be some connection [{337}] of meaning. Perhaps the pair suggests an image or a little story. After a few readings, he has the pairs so well in hand that he can score almost one hundred per cent., if tested immediately.
But now suppose the experimenter springs a surprise, by asking the subject, as far as possible, to recite the pairs in order, or to tell, after completing one pair, what was the first word of the next pair. The subject can do very little at this, and protests that the test is not fair, since he "paid no attention to the order of the pairs, but concentrated wholly on each pair separately". Had he expected to recite the whole list of pairs in order, he would have noticed the relationship of successive pairs, and perhaps woven them into a sort of continued story.
In memorizing connected passages of prose or poetry, the "facts observed" are the general sense and drift of the passage, the meanings of the parts and their places in the general scheme, the grammatical structure of the sentences and phrases, and the author's choice of particular words. Memorizing here is the same general sort of observant procedure as with nonsense material, greatly assisted by the familiar sequences of words and by the connected meaning of the passage, so that a connected passage can be learned in a fraction of the time needed to memorize an equally long list of unrelated words. No one in his senses would undertake to memorize an intelligible passage by the pure rote method, for this would be throwing away the best possible aid in memorizing; but you will find students who fail to take full advantage of the sense, because, reading along passively, they are not on the alert for general trends and outlines. For fixing in mind the sense of a passage, the essential thing is to see the sense. If the student gets the point with absolute clearness, he has pretty well committed it to memory.
