Humans are known for their exceptional sensitivity in their hands and fingers. There are only few animals that come close to our ability to manipulate objects.
Only octopuses, elephants and apes are in a similar league with regards to dexterity and finesse.
- cma 1y agoYou can be born without hands and have zero cognitive deficits. Sensory info and action-feedback from hands, vision, hearing, isn't key to intelligence, but if you are born without vision and hearing it can cause developmental issues, but even if you lose vision and hearing before 2 years you can develop normally, like Hellen Keller.
- dbspin 1y agoActually this is wrong. There's a connection between bodily sensation and emotion so profound that quadriplegics can develop flat affect which in turn leads to decision paralysis and cognitive deficit. Emotions are regulated somatically, and inform decision making and other aspects of motivation and reasoning.
