New hand-eye relationship?

According to this article:

humans more thoroughly inspect objects when their hands are near the object rather than farther away from it. They posit that this processing exists because humans need to be able to analyze objects near their hands, to figure out how to handle them or to provide protection against them.

...

Not only do we see items differently when our hands are near them, we also process the meaning of language differently, Abrams said. Other experiments showed that when reading nonsensible sentences, subjects were less likely to realize that the sentences were illogical when their hands were near the display. This means that humans are less likely to recognize errors when we are holding the something we are reading.
