Over at Sciam’s Mind Matters blog, Greta and I have written a guest post about tone deafness and bad singing: Although there have been many studies of perceptual tone deafness, or amusia, few have compared people’s ability to hear differences between musical notes with their ability to produce good music.

Encephalon is up at Neurocritic

The biweekly neuroscience / psychology carnival Encephalon is now live over at the Neurocritic. There are tons of great posts but one of my favorites has to be this one: Would you vaccinate your kids against drugs?

We’ll be participating in a symposium on Sunday, talking about Cognitive Daily and ResearchBlogging.org, but until then, we’ll be attending other sessions and reporting intermittently here on CogDaily. We won’t be “liveblogging” every…

He promises to offer a new illusion every week, along with an explanation of the science behind it. Here’s a preview of this week’s illusion: For an explanation of how…

Thank you for “choosing” to read Encephalon #44 here at Cognitive Daily. Every two weeks, Encephalon “selects” the best psychology and neuroscience blog posts from around the blogosphere, giving readers the chance to “decide” which ones they’d like to investigate further. Unfortunately for all those involved, those “decisions” very likely weren’t carried out through the…
