Pinning on new flanges:a proposed experiment

Exerps of the same paper :

Reflexes are fully automatic movements. This paper however focuses on
rapid intentionally changes. A distinction should be made between the
motor programs of reflexes and the motor programs influenced by
proprioceptive, senso-motori and kinaesthetic information. Think for
example about the reflex of you hand when you grab a hot object (=
withdrawal reflex). This is a completely automatic and non-intentional
act. Now imagine that your hand reaches for a glass of water with the
intention of drinking it. While you are talking to a friend, the hand,
without being conscious aware of it, shapes itself in a precise way
for picking up the glass. This is a movement which contains at least
some part of intentionality.

Proprioception: sense of position of the limbs and trunk (knowing
where your body is in space)
Kinesthesis: sense of movement in the limbs and trunk (the experience
of movement in your body through space)

What is interesting to know, is that visual information has been
demonstrated to affect performance negatively in movement situations
that require rapid responses. Jordan (1972) studied a group of elite
fencers and found that they actually responded much faster to an
opponent's advancing blade when deprived of any visual information. In
the absence of vision, the athletes were utilising the faster
somatosensory cues provided by cutaneous receptors and proprioceptors.
This means actually that the cutaneous receptors and proprioceptors
are faster than the visual receptors (Rose, 1995).Proprioceptive
information is very useful in the making of rapid bodily changes.
The body challenges its own destination: it postpones, changes and
alternates the movement(s) until the before and after movement
onset..Every movement decision can be replaced by another and again
another movement decision. This is a body in a continuous state of
alertness.
