No Link Between Income And HappinessWhile most people think that having more income would make them happier, Princeton University scientists have found that the link is greatly exaggerated and mostly an illusion.
People surveyed about their own happiness and that of others with varying incomes tended to overstate the impact of income on well-being, as per a new study. Eventhough income is widely assumed to be a good measure of well-being, the scientists found that its role is........Go to the Psychology news blog (Added on 6/30/2006 12:07:51 AM)
With Cochlear Implants"Bye-bye, bye-bye," said one 3 and a half-year old child, born deaf but with a cochlear implant that partially restored hearing nine months earlier. That's the most complex speech the child uttered during a testing session that involved play with a toy train set.
In contrast, a child of the same age who had a cochlear implant 31 months earlier made more sophisticated statements: "OK, now the people goes to stand there with that noise and now........Go to the ENT news blog (Added on 6/29/2006 9:35:03 PM)
