The perception is a complex processing of the sensorial data at the aim of understanding their meaning. The tactile perception ensures the ability of discriminating between heavy and light, smooth and rough, damp and dry, and the ability of recognizing the shape and the size of the things through the tactile exploration. The kinesthetic perception is based on the information carried by the receptors, that are able to record the muscle contraction and the tendons tension. Among the Verbo-Tonal disciplines, the Body Rhythm promotes the maturation of the language by the education of the rhythmical movements and is especially based on the tactile-kinesthetic channel. The child is asked to play some body movements, which are called “the best” because their tension, duration, intensity and direction accord with the language sounds, that is to say with “micro-movements” of the phono-articulatory organs. The relationships between the tactile and the auditory senses and, consequently, the reason for the use of the vibro-tactile stimulation at the aim of promoting the auditory perception are based on the ontogenetic data, that is to say on the common derivation from ectoderm. In the watery environment the vibrations produced by every movements had been recorded by the tactile sense, which was faster than the molecular diffusion. In comparison with the chemical sense, the tactile sense was able to foresee in advance the coming nearer of dangers and to put in action defence behaviours. Following the movement of some species from the watery to the earthly environment, the sight and the hearing reached the priority among the senses in men. The Verbo-Tonal Method proposes some techniques to “control” the auditory output at the aim of making up for the ineffective processing, which is unable to discriminate in a proper way among the several auditory signals. The “control” is carried out on the physical parameters: frequency, intensity, time and rhythm. Coming from the knowledge that the sounds perception is the result of a discontinuous combination of frequencies, the natural device can be replaced by proper filters, which make more intelligible the verbal signal. The study of the visual perception is really useful to understand the complexity of the perceptive elaboration. As regards the visual perception, the perception of depth, the perceptive constancy, and the recognition of the things deserve a specific consideration. The fully developed perception gives the ability of recognizing a thing regardless of the point of observation, and so of the several images shaped on the retina. This phenomenon is basic for the organization of our knowledge and is based on the constancy of the perception, which relates to the shape, the size, the brightness, the colour and the placement in the space. In a few words, according to the Neisser’s cyclic theory the interpretation of the data coming from the environment starts from models of perception rose from concepts and expectations (up to down approach). Then the research of confirmations by perceptive clues is carried out (down to up checking): this check up could show the need of corrections and revisions, which lead to the elaboration of a new model. Within the Verbo-Tonal Method, the Phonetic Graphism proposes the graphic activity to obtain a visual-perceptive translation of the prosodic aspects of the language, which is based on the correspondence between linguistic and graphic rhythms. The Phonetic Graphism is also based on the correspondence between the graphic sign and the perceptive, emotional, kinesthetic and semantic components of the language, which develops better thanks to this pedagogic process. Finally, the perceptive activity is not self-sufficient, but it works oriented by the whole action, that is to say by the sensory-motor intelligence first and then by the representative intelligence. In more details, the operative systems, which are the concepts, are abstracted from the scheme of action, while the perceptions secure the contact between the actions/operations and the objects/events at each moment and in the point of application.
