KSU study finds getting answers right on practice tests improves memory
Akron Beacon Journal: Kent State University graduate student Kalif Vaughn conducted an interesting experiment to determine if getting answers right on practice tests would improve recall not only of the thing you’re trying to remember, but things that trigger that memory and things associated with what you’re trying to remember.

Income disparity causes unhappiness – study
Reuters: As the rich get richer and the poor fall further behind, levels of happiness and satisfaction drop, but only among people with modest and lower incomes, a new study shows. The finding holds true for about 60 percent of Americans, according to research that will be published in the journal Psychological Science. "Income disparity has grown a lot in the U.S., especially since the 1980s. With that, we've seen a marked drop in life satisfaction and happiness," said Shigehiro Oishi, a psychologist at the University of Virginia. Read more: Reuters

Exploring the Dynamic Interaction Between Genes, Environment and the Brain
A Symposium on Epigenetics at the 3rd Scientific Meeting of the ESN 8 September 2011 in Basel, Switzerland Cosponsored by the Association for Psychological Science and the Federation of the European Societies of Neuropsychology With modern advances in a number of scientific disciplines, we have moved from looking at genetic versus environmental factors to looking at the interplay between these factors in understanding individual differences in behavior. In the process of development, the expression of genes is shaped by environmental experience, producing stable changes in individual characteristics that can persist within and across generations.

Instead, the higher your score, the better you perform later. But some critics have said that the tests aren’t much use at the top end of the scale.

Imagining something with our mind’s eye is a task we engage in frequently, whether we’re daydreaming, conjuring up the face of a childhood friend, or trying to figure out exactly where we might have parked the car. But how can we tell whether our own mental images are accurate or vivid when we have no direct comparison? That is, how do we come to know and judge the contents of our own minds?
