The object series were also changed to conform to the movement series.  Formerly the objects had been shown successively through the aperture and synchronously with their corresponding words; now they were on the table in front of the subject and all uncovered and covered at once as in the movement series.  The subjects therefore had a single mental image of these four objects also.

In both the object and the movement series the objects as before were small and fairly uniform in size and so selected as not to betray to the subject their presence beneath the cloth in the I. test.  In the II., III. and IV. tests there were no objects on the table.

The previous table shows the results of the C set.  The figures give the number of couplets correct out of four; the figures in brackets give the number of indirect associations; the total number recalled in any series is their sum.

In the following summary the recall of M and Mo after two days and of S, Hu, B and Ho after twenty-one hours are combined.
