SSSM - Assumptions l 1) The Blank Slate n Most of us can see

SSSM - Assumptions l 1) The Blank Slate n Most of us can see this is silly, but, the SSSM seems to accept it l 2) Biology is Irrelevant n If experience is all that matters, biology really has no effect now does it l 3) There are only a few learning mechanisms

Why the SSSM is wrong… l Development NEEDS biology l So, when you hear

Why the SSSM is wrong… l Development NEEDS biology l So, when you hear say language, you learn language, as a kid. l No matter how many hockey stats I flash at you, you will not become a hockey stats expert by the age of 4. l Why?

Another example or two… l Why can’t my parents’ dog learn to speak English?

Tinbergen’s ‘Four Whys’ l Proximate vs. Ultimate explanations l Development l Physiology l Historical

Tinbergen’s ‘Four Whys’ l Proximate vs. Ultimate explanations l Development l Physiology l Historical l Selective l Psychology has concentrated on proximate, and that is fine, but it only tells half of the story

Human Nature l Margaret Mead l All culture, all social, no effect of biology l Had a big effect in anthropology and sociology not to mention us l Umm turns out it is wrong… l Universal people l Hard to change a hundred years worth of scholarly work though

Just because there is human nature…. . l It does not mean stuff is

Just because there is human nature…. . l It does not mean stuff is unchangeable l Variability due to environmental variability and variability in genes l And, of course the interaction thereof l Many examples, the book has a nice bit on violence l Killer sperm and cheating

Naturalistic Fallacy l Just because something has a genetic basis we do not make

Naturalistic Fallacy l Just because something has a genetic basis we do not make the judgment that it is right or wrong l Science is amoral l Society has determined that monogamy is cool, polygyny is not l We may be hooked up to be polygynous, but most of us are faithful

Conclusion l The EEA influences us l Generals always fight the last war l

Conclusion l The EEA influences us l Generals always fight the last war l Don’t forget about the levels l Just because something is biological does not make it right or wrong
