I'm sure you meant to say "born [b]without traits of any kind". I feel that a significant part of personality must be genetically derived. That's only my opinion, based on the differences I've seen between twins.[/b]
Yes it was a tpyo 😀 ...
Birth to 2 years is classed as the sensorimotor period, which in essence means a pretty much egocentric thinking period. i.e. the world doesn't really exist apart from one's own experience of it. It's a time of development of object permanence; in other words developing the idea that objects do actually exist independently of one's own perceptual or sensory experiences, which I personally believe are very hereditory.
The broadest issue in forming a theory of development, and in some ways the most contentious, concerns the origins of the changes which occur over the span of life. In some ways, development represents a paradox: there is an obvious sense of change, while at the same time there seems to be a central thread of constancy. For example, parents of grown children often recall ways in
which an infant or child foreshadowed the adult, as they say.
Is this constancy real or imagined? And if real, what is it based on?
The traditional answer to the question of constancy has been to assert that the basic characteristics of a person are innate – that is, the constancy is due to the influence of heredity. In essence, this is the modern version of Plato’s nativist theory. The role of heredity is evident in the development of a foetus, whereby cells differentiate to form the various parts of the body. Even after birth, the regularity of growth strongly suggests the influence of genetic timetables, in my IMHO of course.
