PLoS ONE “Probing the Strength of Infants’ Preference for Helpers over Hinderers: Two Replication Attempts of Hamlin and Wynn (2011)” Great example of how studies need to be replicated! I am wondering if funding agencies should reserve particular lines for replication studies. Does this kind of funding opportunity exist?

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

This is a fascinating talk by Jonathan Haidt, a psychologist situated within one of the most prestigious business schools in the world whose research focuses on morality and emotion. I can’t help but be impressed when someone addressing business concerns leads with biology, and Haidt does a good job of summarizing the “disruptive cooperation” (read: competitively-superior Read More

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

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

The New York Times “China to End One-Child Policy, Allowing Families Two Children” This was a long time coming (see Mara’s Hvistendahl‘s great 2010 piece in Science Magazine for perspective), but the Chinese Communist Party has finally decided to replace its “one child policy” with a “two child policy”. From an evolutionary perspective, there is Read More
