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…

Pouches, pockets and sacs in the heads, necks and chests of mammals, part I: primates
I've mentioned laryngeal and tracheal anatomy a few times on Tet Zoo (see the links at the very bottom for more). Well, time to look at it again. It's (relatively) little known that a long list of mammal species possess an assortment of 'pouches', pocket-like structures and pneumatic sacs and spaces within their throats, skulls, chests, and sometimes on their palates. Some of these are air-…
The Glaciers Will Melt, The Sea Will Rise Up
Sea levels are going to rise The amount of carbon dioxide in the Earth’s atmosphere directly and indirectly determines the sea level. The more CO2 the higher the sea level. The details matter, the mechanism is complex, and as CO2 levels change, it takes an unknown amount of time for the sea level to catch up. The present day level of CO2 is just over 400ppm (parts per million). For thousands of…
