Comparative Effect of Various Articulatory Conditions on the Processes of Perception, Memorization, and Thought
From the psychophysiological point of view it is obvious that the method of speech interference (enunciation of extraneous word series or syllables during simultaneous auditory perception of speech) used in the preceding experiments was based on the effect on the nerve processes of negative induction which arose in the speech areas of the cerebral cortex as a result of an incoming flow of afferent kinesthetic and auditory impulses due to extraneous verbal stimuli. This technique made it possible to elucidate the role played not only by external (overt) but also by internal (concealed) articulation in the process of mental activity and, moreover, not only at the peripheral but also on the central (cerebral) level.
