The investigation of involuntary speech movements is a study which has many points of contact. At one extreme there is the attempt to disprove the theory of "imageless-thot" by demonstrating that movements of subvocal articulation are, under normal conditions, always present, and that one may therefore assume the presence of kinesthetic sensations, resulting from such movements. If the movements themselves are so much a part of the thot processes, it is probable that images of a knesthetic-verbal type should accompany them likewise. So, if no concrete visual, auditory, or motor imagery need be present in thinking, at least imagery of the throat musculature permits of no evasion.
