A13-16 had five presentations instead of three. The test consisted in showing the subject either the numbers or the words in altered order and requiring him to write as many of the absent terms as he could. In the object and movement series the objects were also shown and the movements repeated by the subject if words were the given terms. The time conditions in the test were,
| Exposure of a term | 3 secs. |
| Post-term interval in A1-12 | 4 secs. |
| Post-term interval in A13-16 | 6 secs. |
This allowed the subject 7 secs. for recalling and writing each term in A1-12 and 9 sec. in A13-16. If a word was recalled after that time it was inserted, but no further insertions were made after the test of a series had been completed. An interval of 3 min. elapsed between the end of the test of one series and the beginning of the next series, during which the subject recorded the English word of any couplet in which an indirect association had occurred, and also his success in obtaining visual images if the series was a noun or a verb series.
As already indicated, four series—a noun, an object, a verb, and a movement series—given within a half hour, constituted a day's work throughout the year. Thus variations due to changes in the physiological condition of the subject had to affect all four types of series.
Two days later these series were tested for permanence, and in the same way as the tests for immediate recall, with this exception:
| Post-term interval in A13-16 | 8 secs. |
Thus 11 secs. were allowed for the deferred recall of each term in A13-16.
In the movement series of this set, to avoid hesitation and confusion, the operator demonstrated to the subject immediately before the series began, once for each word, how the movements were to be made.
The A set was given to three subjects. The results of each subject are arranged separately in the following table. In the tests the words were required in A1-4, in A5-16 the numbers. The figures show the number of terms correctly recalled out of seven couplets in A1-12 and out of five couplets in A13-16, exclusive of indirect association couplets. The figures in brackets indicate the number of correctly recalled couplets per series in which indirect associations occurred. The total number correctly recalled in any series is their sum. The figures in the per cent. row give the percentage of correctly recalled couplets left after discarding both from the number recalled and from the total number of couplets given those in which indirect associations occurred. This simply diminished the subject's number of chances. A discussion of the propriety of this elimination will be found later. In A1-12 the absent terms had to be recalled exactly in order, to be correct, but in A13-16, on account of the greater difficulty of the three-place numbers, any were considered correct when two of the three figures were recalled, or when all three figures were correct but two were reversed in position, e.g., 532 instead of 523. N means noun series, O object, V verb, and M movement series. Series A1, A5, A9, A13 are to be found in the first and third columns, A2, A6, A10, A14 in the second and fourth, A3, A7, A11, A15, in the fifth and seventh, and A4, A8, A12, A16 in the sixth and eighth columns.
