Talk:Psychological adaptation

From Wikipedia, the free encyclopedia

"The least controversial EPMs are those commonly known as instincts, including human capacities for digestion, interpreting stereoscopic vision, suckling a mother's breast, etc." ---I don't know that digestion is a psychological process or type of behavior. It is a physiological/biochemical process largely outside the bounds of cognitive action. I don't believe it belongs grouped with instincts.

I think this highlights the fuzziness of the boundary between what's considered "psychological" and "non-psychological" in human behavior... I'm not familiar with the details of CNS/PNS/hormonal aspects of control of digestion, but certainly there are neural structures that govern it, that evolved for that purpose, and that produce muscle behavior in response to the environment (presence of food). This isn't fundamentally different from other psychological adaptations, because they need not be consciously (another imprecise term) controlled or mediated through emotions or motivational states or anything else more typically "psychological."
