It leads to development of a subjective sense that refers to observing, knowing, introspecting, and self-respecting self through the subject’s own perspective or viewpoint through the eye of mind. The experience of self or sense of agency develops essentially through maturation of fundamental psychological functions of the individual, and in this essay, this author shall explore the steps of development of agency in a child, its importance, and the factors that might hinder its development (de Vignemont , F. and Fourneret, P., 2004). The human development is a complex process. The early years of a child’s development is characterised by rapid and astonishing growths of the physique and psyche. It apparently happens as a smooth, natural, and spontaneous process in front of millions of eager watchers in the families, but to the neurobiologists, behavioural scientists, psychologists, and psychotherapists, it has remained an enigma, and as a result, major advances in research have imparted to understanding of the conditions promoting a normal or abnormal development of such an agency. This understanding is important from the therapeutic point of view since this sense of agency determines whether a child will get off to a promising or devastating start in life that will have major implications in the future psychological health of the individual (Bertalanffy, L. V., 1968).
