She states there is no clear distinction between cause and effect in regard to intention and action. This is because different factors falsify this stance, i.e. the making use of history.
She uses the concept of the body-schema which is derived from neurophysiology. This concept holds within that there is a mental intention and bodily intention. The body is regarded as the subject of action, representation and reflection. But from the less causal view that it is the organ not the instrument. Things become more organic in reality.
Bodily intention is nothing more than oriented bodily expression! The body-schema is defined as a combined standard against which all subsequent changes of posture are measured, ... Before the changes of posture enter consciousness.
The body-schema does not equal body-image but rather contains it in part. This is within a context of regulation. The body-image is defined as a (sometimes conscious) system of perceptions, attitudes and beliefs which pertains the own body.
So the body-schema is more dynamical and executive. More focused towards the action than towards reason. In short it is more about performance than conception. It is selectively attuned to its environment as it organizes the incoming information from the stimuli in relation to pragmatic concerns. It can be linked to consciousness and it is important for the development of perceptual consciousness.
Since the body-image needs perceptual identification there could be a turn back from the body-schema. Which in turn has effect on intentional orientation of the body-schema. But there is no necessary function from the body-image to have a body-schema.
Although the distinction between action and perception seems to be a better one than the distinction between reason and action, there is no extensive literature about this. Often the link between behavior seems to be more strong than the one between perception, i.e. Titchener illusion.
There could be said that perception is a source of information but that action brings to another format within a process of integration. The most important brain-part is the frontal lobe. Otherwise there is developing an environmental dependency syndrome. In this, there is too much influence of the environment.
Perception can change during bodily intentions. This has been called intentional binding. Which becomes involuntary movement. So integration causes a reincarnation of a self while introspecting and the mind itself has manipulative effect.
