Neuroscientists Can Predict Your Behavior Better Than You Can
A new study using magnetic resonance imaging (MRI) on 20 test subjects found that the researchers could determine certain future choices better than the subjects themselves.
The author of the study says that “There is a very long history within psychology of people not being very good judges of what they will actually do in a future situation.” While the study was limited to determining whether people would use sunscreen during a one-week period, hypothetically, advertisers will be able to create very accurate focus groups where participating individuals will show not what they think they will do, but what they actually will do.
Imagine advertisers knowing better than we do whether we will buy something. Do you buy things because of advertisements?
Chewing Ice May Mean You’re Anemic
Do you chew ice all the time? It may be a sign that you have iron deficiency anemia. Compulsive ice chewing, called pagophagia, may relieve mouth inflammation caused by iron deficiency. Studies have also found a relationship between craving ice and the weight loss surgery procedure Roux-en-Y that bypasses a part of the intestine where iron is most easily absorbed. In extreme cases, chewing too much ice may damage your teeth. Happily, if you’re an ice eater and aren’t getting enough iron there’s an easy fix: taking iron supplements.
Double Hand Transplant Doing Well
A 34-year-old Polish soldier who lost both hands in a training accident has undergone a successful 17 hour operation-- the first one of its kind in Poland-- to transplant both hands. The new hands are from a female donor.
Hand transplant surgery began in 1964, but was unsuccessful until an operation in France in 1998 on a convicted con-man. The first double hand transplant deemed a success was in 2004. Medical science continues to improve at a rapid pace and help an ever greater number of people lead happy, productive lives.
