Cognitive Daily Closes Shop after a Fantastic Five-Year Run
January 20, 2010
Five years ago today, we made the first post that would eventually make its way onto a blog called Cognitive Daily. We thought we were keeping notes for a book, but in reality we were helping build a network that represented a new way of sharing psychology with the world. Cognitive Daily wasn't the…
Both musicians and non-musicians can perceive bitonality
January 20, 2010
Take a listen to this brief audio clip of "Unforgettable." Aside from the fact that it's a computer-generated MIDI performance, do you hear anything unusual? If you're a non-musician like me, you might not have noticed anything. It sounds basically like the familiar song, even though the…
Synesthesia and the McGurk effect
January 14, 2010
We've discussed synesthesia many times before on Cognitive Daily -- it's the seemingly bizarre phenomenon when one stimulus (e.g. a sight or a sound) is experienced in multiple modalities (e.g. taste, vision, or colors). For example, a person might experience a particular smell whenever a given…
Does watching TV really kill you?
January 12, 2010
Today I had to put off my normal morning run in order to make time to be interviewed on a radio show at 7:30 a.m. As I waited on hold for the interview to start, I could hear the hosts joking back-and-forth about what the "latest TV controversy" is. "Is it the Jay Leno / Conan O'Brien news on NBC…

What happened with that Sumerian 'sivathere' figurine after Colbert's paper of 1936? Well, a lot.
I don't do requests on Tet Zoo, but when enough people ask me about the same thing it does get into my head. Ever since the early days of ver 1 people have been asking me about late-surviving sivatheres. What, they ask, is the deal with those various pieces of rock art and that Sumerian figurine - discovered in Iraq - that apparently depict Sivatherium? As most of you will know, Sivatherium was…
The Size of the Universe: A Hard Question
I get a certain question every so often, and it's one of the most difficult questions any cosmologist faces. Today, I try to tackle it. It goes something like this: If the Universe is 13.7 billion years old, and nothing can go faster than the speed of light, how is it that we see things that are 46.5 billion light years away? First off -- and I want to clarify this -- everything in this question…
How Hydrogen Teaches Us the Temperature of Dark Matter!
"Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe. I dispute that. I say there is more stupidity than hydrogen, and that is the basic building block of the universe." -Frank Zappa Oh yeah, Zappa? Well, let me show you what hydrogen can do! With just one proton and one electron, hydrogen is not only the simplest of all the atoms in the…
