Esse italiano é do caralho, seus posts são sensacionais. Pronto, agora que já puxei o saco posso copiar indiscriminadamente seu excelente post.

Birds build their nests instinctively and many animals “know” how to hunt or find food, but human beings have a very simple set of instincts, such as those for suction and for grabbing. Everything else comes from a process of learning, which is very much an embodied process.

In the evolutionary route, we first see the muscles appearing, and then motor functions, as consequences of living in a certain habitat, and later the associated neuro-physiological functions. The motor activity acts on the brain which in turn acts back on the body allowing a more perfected action.

As mãos entram em cena:

The hand especially, with its subtle movements, shaped our nervous systems more than any other motor activity of the body. The “technologies” of body movements and of manual labor shaped and developed our brains since primitive times. In mutual feedback, our brains shaped our tools in growing complexity until we arrived at contemporary tools which interact almost exclusively with our minds.

Whether we use IT which interact primarily with our minds or mechanical technologies mainly through our bodies, they affect our body/mind even in permanent ways.

Technology, even in our hi-tech era, is still something which keeps a connection, though faint, to our hand. The only body movements we do when we use hi-tech tools are by our hands and fingers, through the mouse, the keyboard or a touch screen.

The wider neural connections are between the hand and the brain. Handwriting itself, with its subtle and highly personalized movements, can even give a glimpse of our personality through graphology.

Ivo faz uma pergunta interessante:

What happens when we use technologies which interact almost exclusively with our minds with no or mininal involvement of the body, apart from the obvious cardio-vascular and obesity risks in sitting for a long time in front of a screen?

As a culture, we didn’t investigate what happens when we substitute all manual with mental labor, which tends to have direct contact between our minds and the instrument. For instance, if London’s taxi drivers develop a part of the brain according to their navigational efforts through London’s streets, what happens when we rely on GPS for our navigation? As a personal anecdote, one of my acquaintances drove his car from the south to the north of Italy. When I asked him which route he took and whether he passed one town I named or another, he answered that he didn’t notice because he just followed GPS indications. Is there a possibility the same brain areas atrophy which become developed in taxi drivers?
