Cognitive Daily

Archives for November, 2007

Two weeks ago, we challenged our readers to see if they could discern the difference between MP3 recordings at different sampling data rates. Nearly 700 completed our study. So does a very high data rate result in a noticeable difference? Here our are basic results: Respondents rated two recordings, one by rock guitarist Carlos Santana,…

Thumbnail book review: Storm World

I’ve just finished reading fellow ScienceBlogger Chris Mooney‘s new book Storm World, and I highly recommend it — not only to people interested in hurricanes and global climate change, but also to fans of cognitive psychology. Why psychology? Because the book offers an excellent case study of how scientific research becomes part of the popular…

Do people ever tell you to “just smile, you’ll feel better”? If you’re like our daughter Nora, you hear it a lot, and you get annoyed every time you hear it. Telling a teenager to smile is probably one of the best ways to ensure she won’t smile for the next several hours. But the…

Suppose you’re playing a game where the goal is to accumulate as many points as possible. Now suppose your decisions — and only your decisions — control not only how many points you get, but also how many points the other player gets. Suppose further that at the end of the game, you’ll be able…

Casual Fridays: Are all MP3s equal?

Recently I saw a blog post suggesting that the methodology for many so-called studies on the phenomenon was flawed. If you’re going to test…

We didn’t get many suggestions, and commenter Keely had a guess as to why: Perhaps what would be more helpful is to post links to the articles YOU were thinking about, and we could sort of vote on…

Have you been following the progress over at BPR3? Here’s an update: With the release of the Research Blogging icon, dozens of blogs and hundreds of posts are already showing the world when they are discussing peer-reviewed research. But the next step will be far more dramatic: a site which consolidates all those posts in…
