[4] Thelen applied chaos theory to the research of how babies learn to walk and interact with the world around them.
[5] In Thelen's view behavior emerges as a pattern from all the streams that flow into the river of infant development.
[6] She suggested that an infant already has basic motor patterns at birth as demonstrated by stepping reflex and spontaneous kicking.
Thelen's contribution in this area involves the notion that the nature of physical development is not absolute but flexible.
[10] According to Thelen, development is self-reorganization (with the self pertaining to the system instead of the psychoanalytic self) that emerges due to the interaction of the system/organization/person with another or the environment.
[8] Edelman used the terms reentrant and degenerate in order to describe these complex neural connections.
Reentrant was defined as a complex interwoven system in which the output can feed back into the input.
As stated in the dynamical systems theory in order for movement to occur, the control parameter must be scaled up above the threshold.
These factors include transiet and tonic visual input and the infants memory of the toy location.
