Who's the liar? Brain MRI stands up to polygraph test. Traditional polygraph tests to determine whether someone is lying may take a back seat to functional magnetic resonance imaging (fMRI), according to a study appearing in the February issue of Radiology. Researchers from Temple University Hospital in Philadelphia used fMRI to show how specific areas of the brain light up when a person tells a lie. [Science Blog -]

The Screening Room, episode 1.
Today I'm introducing a new feature called The Screening Room. It will be a monthly series of screencasts exploring new software that strikes me as both interesting and important.

She thought he loved her tuna casserole; he surreptitiously slipped it to the dog. He thought she loved massages; they actually caused her back pain. Turns out, though, that they're not alone. Researchers from the University of Michigan and Columbia University recently compared how well people think their friends know them to their actual taste in movies and restaurants. They found that we tend to overestimate personal information more in close friends than in acquaintances. [Science Blog -]

e-Assessment Lit Review. I saw this literature review on e-assessment pointed to by Jeremy Williams (The Authentic Assessment Website), and thought I'd better mark this one down. I love Jeremy's description; he calls it "... little UK-centric, but a jolly good read all the same." Literature Review of E-assessment (A Report for NESTA Futurelab, Jim Ridgway and Sean McCusker, School of Education, University... [Michelle's Online Learning Freakout Party Zone]
