Influence in Traditional Social Networks

While Facebook, MySpace and other social networking sites continue to receive a lot of attention, the real influence may lie within traditional social networks [washington post]:

When researchers analyzed the patterns of those who managed to quit smoking over the 32-year period, they found that the decision appeared to be highly influenced by whether someone close to them stopped. A person whose spouse quit was 67 percent more likely to kick the habit. If a friend gave it up, a person was 36 percent more likely to do so. If a sibling quit, the chances increased by 25 percent.

A co-worker had an influence — 34 percent — only if the smoker worked at a small firm. The effects were stronger among the more educated and among those who were casual or moderate smokers. Neighbors did not appear to influence each other, but friends did even if they lived far away.

“You appear to have to have a close relationship with the person for it to be influential,” Fowler said.

Using Brain Scans to Identify the Language of Thought

Dr. Mado Proverbio and researchers at the Milano-Bicocca University in Milan have found differences in EEG amplitude levels when processing language learned to proficiency before the age of five when compared to “second language” processing [msnbc]:

For more than a year, a team of scientists experimented on 15 interpreters, revealing what they say were surprising differences in brain activity when the subjects were shown words in their native language and in other languages they spoke…. Proverbio attributed the differences to the fact the brain absorbs the mother tongue at a time when it is also storing early visual, acoustic, emotional and other nonlinguistic knowledge. This means that the native language triggers a series of associations within the brain that show up as increased electrical activity.

“Our mother tongue is the language we use to think, dream and feel emotion,” Proverbio said.
