It's a great way to familiarize yourself with cutting-edge research, such as the effects of music on plant growth, or the effects of soda on plant growth, or the reasons budding young scientists should never, ever be allowed to own hamsters. One student did a project about landfills. Her background research described the importance of preventing the release of certain chemicals into the atmosphere -- chemicals such as dihydrogen monoxide (DHMO). Before announcing your find, don't forget to remove the quotation marks around words such as 'expert' and 'discovery.' Delete winking emoticons, too. I smiled when I read that. The "evils" of DHMO are part of a famous science hoax, a very funny one that supposedly began more than 20 years ago on the University of California, Santa Cruz, campus. It crops up every so often. Propaganda opposing DHMO cites the substance's presence in acid rain, use in naval warfare, and the fact that professional athletes can become dependent on its performance-enhancing abilities. Seriously, you should conduct a Google search of DHMO if you haven't seen this list. It's even funnier than that YouTube video showing the dancing Christmas tree surprising the cat. (If you haven't figured out yet what dihydrogen monoxide is, write out the chemical formula. Really? Okay, it's water. Now go tear up your doctoral diploma.) I used to use the dihydrogen monoxide hoax on the first day of a class I taught about the public perception of science. After distributing a DHMO "fact sheet" detailing its dangers, I'd ask the students to decide the fate of this chemical. Most semesters, between one-quarter and one-half of the students voted to regulate or ban outright the scary-sounding DHMO. These were college students. Mostly science ma

What does the term 'measurement' mean in a psychological context? This fascinating and timely book discusses these questions and investigates the possible answers that can be given experimental error forging response. Denny Borsboom provides an in-depth treatment of the philosophical foundations of widely used measurement models in psychology. The theoretical status of classical test theory, latent variable theory and positioned in terms of the underlying philosophy of science. Special attention is devoted to the central concept of test validity and future directions to improve the theory and practice of psychological measurement are outlined.
