Can a realistically-parameterized model tell us why our brains are so big?

Posted 30 Aug 2018 / 0

Nature “Sizing up human brain evolution” Nature “Inference of ecological and social drivers of human brain-size evolution” This is an interesting study that I simultaneously think is really cool and has some major flaws. What’s cool about this study is that it trys to get at this question with a model that’s (reasonably) constrained by observed parameter Read More

Urban Wildlife Podcast on Hedgehogs, Raccoons, and Urbanite Biophilia

Posted 16 Jan 2017 / 0

My Spring semester is almost upon me, and that means a lot of mindless computer work getting my classes configured. I love these moments, because they give me the chance to catch up on my favorite podcasts. I hadn’t checked out the Urban Wildlife Podcast in too long, and was excited to find that Tony and Read More

FDA investigators raid American Society of Human Genetics offices in Carl Zimmer cloning case

Posted 01 Apr 2016 / 4

Investigators from the United States Food and Drug Administration raided the offices of the American Society of Human Genetics this week. The unusual raid was the culmination of what has been a three-year investigation of science journalist Carl Zimmer, who is now being accused of cloning himself in order to increase his writing output. “We Read More

What’s the evolved function of curiosity?

Posted 06 Nov 2015 / 0

Image courtesy of Jeffrey Pang via Wikimedia Commons Neuron “The Psychology and Neuroscience of Curiosity” (Kidd & Hayden 2015) This is a fantastic review of what is known about curiosity and what needs to be learned about curiosity in the near future. I was glad to see the “four questions” approach to curiosity here. Tinbergen’s questions Read More

Does Bayesian bias aid us in making adaptive distorted self-assessments?

Posted 16 Oct 2015 / 0

Proceedings of the National Academy of Sciences “Receipt of reward leads to altered estimation of effort” This is an interesting study because it suggests that we can make rational but distorted assessments of their own efforts based on what reward they bring. What’s interesting is that we tend to belittle our own efforts when they Read More

My testimonial for Gregory Tague’s “Evolution and Human Culture”

Posted 05 Oct 2015 / 1

Tague’s Evolution & Human Culture, forthcoming on Brill. Here’s my finished testimonial for this book: Between the age-old outposts maintained by Read More

So much for the big-brained city bird theory?

Posted 05 Aug 2015 / 0

BMC Ecology “Commonness and ecology, but not bigger brains, predict urban living in birds” What makes this study smart is that it compares the birds that live successfully in urban areas with the birds that actually have the potential to colonize cities. This makes for a much more meaningful comparison than simply comparing urban species Read More

Apparently I should stop holding my breath for the Google Translate “dolphin” module

The Chronicle of Higher Education “Dolphin Talk and Human Credulity” Great short here (and further evidence that TED Talks entice scientists to lose their heads and say unfounded things). Anyone who has carefully watched a child learn to talk comes to realize what a complex dance between cognition anatomical coordination is involved in language acquisition. It is Read More

0.5% to 3%: Do we now have a better sense of what makes people smart?

Posted 20 May 2014 / 0

The Economist “A potent source of genetic variation in cognitive ability has just been discovered” A new gene variant, KL-VS, appears to account for up to 3% of variation in IQ score; this would be a radical discovery given that past gene screens have only found variants accounting for as much as 0.5% variation in Read More

Do we need to delete to keep the web sustainable?

Posted 05 Feb 2014 / 2

WNYC New Tech City “The World Would be a Better Place if We [DELETED] More” The title of this piece is a bit misleading, because on the cognitive side it is really unclear to me that forcing ourselves to memorize things would make our lives better (those who know me know that I am “anti-memorization”, Read More
