**1. Introduction**

The proprioceptors are sensory receptors that refer to the qualities of movement in the postural dynamics and displacements of the body in space; sense that for a human being is determinant in the perception of himself in a here and now. We call this phenomenon proprioceptive perception, which modulates the emotional states of the individual given the circumstances of the present.

Proprioceptive perception is a complex phenomenon of dynamic character that results from the modulation of phenomena of different orders such as physiological, relational and interpretative. In this chapter we will address the questions of how, in the epigenesis of a human being, proprioceptive perception affects his capacity to become aware of his corporeal existence within his contextual situation with others

and with the environment in which they exist, moment by moment; and how the proprioceptive experience modulates -in a present- his emotional states in relation to the immediate interactive context maintaining physiological states of the organism congruent to the present circumstances, conserving in adaptation his life in the space in which it exists.

To answer these questions, we will first situate ourselves from a dynamic systemic perspective that reformulates the concept of effective behavior and cognition that derive from the classical vision of neuroscience and psychology based on the Cartesian reductionist functionalist paradigm. This last one understands cognitive phenomena from a representational perspective, where cognition is conceived as an information processing that results in a faithful representation of an external world that operates independently of the organism that perceives it. This has kept science in search of an understanding of the principles and laws of an objective external world, which explains why in the study of perception, there is a prevalence over the exteroceptive senses of an individual (vision, hearing, touch, smell and taste), ignoring the incidence in the sensory integration of the proprioceptive and interoceptive senses. In second place, we will approach how in the origin of the first living organisms are constituted the generative sensorimotor mechanisms of the movements of the effective behaviors that reveal the knowledge of the living beings, to know that it is source and origin of the way of knowing proper of the *Homo sapiens*: the reflection. Next, we will explain how the synchronization between attentional reflexive movements and corporal movements gives origin to the proprioceptive perception that makes possible the differentiation of the external and internal space of the individual. And following with the phenomena of the emotions, we will explain the characteristics of the ways of moving of a human being and how the proprioceptive perception influences the modulation of these in relation to the conservation of the well-being of the organism in its structural coupling with the environment. It explains the concept of emotional plasticity and the type of practices that restore it, showing evidence of its effectiveness.
