can perhaps be explained in terms of cue-producing responses. Sleep-learning is verbal and should be considered as an important new aspect of the thought process. Dr. Hollander's description of subconscious activity comes closest to explaining the process by which we learn in our sleep. Ideas are suggested to the subconscious, which absorbs them and supplies them to the conscious when they are needed, by its own mysterious process of selection. Repetition renders many learned acts unconscious and these are always accessible to us —barring repressive disturbances. Updegraff attests that the subconscious can be put to use consciously and deliberately. Sleep-learners simply go one step further. Sleep-learners' experience in breaking habits indicates that Dunlap's time-effort-consuming approach to negative practice is unnecessary self-punishment. The power of the subconscious can apparently be harnessed through sleep-learning.
