Surging share of Americans consider themselves lower class

Chris Roquemore once thought of himself as working class. But it's hard to keep thinking that, he said, when you're not working.

The 28-year-old father said he sparred with his supervisors at a retail chain about taking time off after his mother died — and ended up unemployed. Since then, Roquemore has worked odd jobs and started studying nursing at Long Beach City College, trying to get "a career, not a job." All those changes, in turn, changed the way he thought of himself.

Roquemore is among the small but surging share of Americans who identify themselves as "lower class." Last year, a record 8.4% of Americans put themselves in that category — more than at any other time in the four decades that the question has been asked on the General Social Survey, a project of the independent research organization Norc at the University of Chicago.

The rising numbers surprised some researchers and activists even in light of the bruising economy. Read more >>

Brain Scans Show Who You're Thinking About

Scientists scanning the human brain can now tell whom a person is thinking of, the first time researchers have been able to identify what people are imagining from imaging technologies.

Work to visualize thought is starting to pile up successes. Recently, scientists have used brain scans to decode imagery directly from the brain, such as what number people have just seen and what memory a person is recalling.

They can now even reconstruct videos of what a person has watched based on their brain activity alone. Cornell University cognitive neuroscientist Nathan Spreng and his colleagues wanted to carry this research one step further by seeing if they could deduce the mental pictures of people that subjects conjure up in their heads.

“We are trying to understand the physical mechanisms that allow us to have an inner world, and a part of that is how we represent other people in our mind,” Spreng says. Read more >>
