Religious children are less altruistic… or maybe not…

Posted 16 Nov 2015 / 0

Image courtesy of Wikimedia Commons A recent study published in Current Biology claims to have demonstrated that children raised in religious households are less altruistic and more vindictive than their peers raised in non-religious households. Using two different tests — a Dictator Game conducted with stickers and a task that measured reactions to watching interpersonal Read More

Fascinating and clever study of how personal contact norms vary by relationship

Posted 10 Nov 2015 / 0

Image from PNAS Proceedings of the National Academy of Sciences “Topography of social touching depends on emotional bonds between humans” (Suvilehto et al. 2015) This is a really clever study in that it aggregates a lot of data that is collected rather efficiently from a lot of participants. This makes the results robust for this Read More

That beard and deep voice may be to put him in his place, not attract her

Posted 09 Nov 2015 / 0

There have been a lot of evolutionary psychology experiments that have tried to define both female and male attractiveness to the opposite sex, an indirect way to get at the nature of sexual selection in humans. A new study published in Behavioral Ecology reminds us that sexual selection is not the only process that has Read More

Are parasites really ecologically necessary?

Posted 20 Oct 2015 / 0

Frontiers in Ecology and the Environment “A world without parasites: exploring the hidden ecology of infections” I was really excited to read this article because this is an issue that I have thought a fair bit about. As you will know if you have read my posts before, I am not the biggest fan of Read More

Does the ability to accumulate wealth make us value the future more?

Posted 29 Sep 2015 / 0

PLoS ONE “Future Discounting in Congo Basin Hunter-Gatherers Declines with Socio-Economic Transitions” These findings are really fascinating, because they suggest that some degree of “building towards the future” is inspired by the ability to accumulate wealth. There’s a lot in these findings to explain why small-scale societies stay small and how larger-scale societies evolve from smaller-scale Read More

Urban Wildlife Podcast on Cats and Coyotes

Posted 20 Sep 2015 / 0

Urban Wildlife Podcast “Episode 4: Cats and Coyotes” What I really enjoyed about this particular episode of the Urban Wildlife Podcast was the interaction between topics covered. The effects of both cats and coyotes are still largely unknown, even as both animals are fairly common in urban areas. Domesticated cats are pretty easy to track Read More

Our paper on a super-rational solution to the tragedy of the commons published in Scientific Reports

Posted 14 Jan 2015 / 1

I am very pleased to announce that a paper that I worked on with collaborators Jun-Zhou He, Rui-Wu Wang, and Yao-Tang Li has been published in the open-access journal Scientific Reports. The paper, entitled “Asymmetric interaction paired with a super-rational strategy might resolve the tragedy of the commons without requiring recognition or negotiation“, considers how Read More

When Facebook performs a manipulative experiment on its users, the results are interesting, the methods disturbing

Posted 03 Aug 2014 / 0

Did you know that Facebook performs scientific research? If I told you that Facebook is constantly analyzing the activity of its users, that would probably not surprise you. But does Facebook go the next step by performing manipulative experiments on its users? A recent publication in the prestigious Proceedings of the National Academy of Sciences USA 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

Cognitive Ethology and Cat Companionship

Posted 17 Mar 2014 / 0

The Chronicle of Higher Education “Animal Magnetism” I still think that we would be appalled and offended if we could literally read the inner emotional dialogue of a cat, but I have to agree with the main contention of Barash and Lipton: that animals have feelings and connections with each other — and sometimes with Read More
