The word association method of Jung is less open to objection on the ground of arbitrariness, and its operation is simpler. A list of anything from a dozen to a hundred or more words is made out. The first half-dozen words have usually no particular significance, but then follow a series of words believed to be specially associated with the different types of complex which may become split off from consciousness; lists of these have been worked out by different students of this school, but although one of these lists is usually used as a basis, the analyst generally inserts words which he believes will especially bear upon the patient’s particular problems. These words are called out to the patient, one at a time, and he is instructed to utter the first word that comes into his head in connection with each. The time he takes to do this is taken by a stop-watch usually working to one-fifth of a second. The first half-dozen of unimportant words will show the patient’s average reaction time, but if any words among the subsequent ones have special significance for him, there will be a perceptible lengthening of the time he takes to reply; moreover the replies may be curious, and either show special bearing upon his problems, or, by their irrelevancy, show that the original idea was discarded as unspeakable and a substitute hastily extemporised. If the list be read over again it will be found that, whereas those words which have no special significance are usually responded to by the same reaction word, those which bear upon the patient’s emotions produce a change in the reaction word. Free association is then resorted to, as in the case of dream symbols, to discover the underlying train of ideas and the factors in the subconscious from which they derive their emotion. Many Freudians make use of this method also, and indeed the two methods of dream analysis and word association are generally regarded as supplementary. The chief value of the latter lies in the fact that it can be used in cases where the patient is either unable or reluctant to co-operate.
