Why do we have brains? To survive (and perpetuate our genes). Not to be right, or make sense, or be logical. Which is the whole point behind evolutionary psychology, a very fun field. Anyway, 2 pieces today made me think of this.
One, Could our big brains come from Neanderthals?, saying that “Neanderthals may have given the modern humans who replaced them a priceless gift — a gene that helped them develop superior brains, U.S. researchers reported Tuesday. And the only way they could have provided that gift would have been by interbreeding, the team at the Howard Hughes Medical Institute and the University of Chicago said.”
Two, Cognitive Daily has a great post on how Motivation Affects Visual Perception, summarized with “These studies provide pretty strong evidence, then, that participants’ object perception was affected by their motivation to eat or drink something that tastes good, or at least by their motivation not eat or something that looked like it would taste really bad.”
