Preschool Promises: Starting Early on a New Educational Agenda for the United States
Two children, both age 3, enroll in publicly funded preschool. But they may have vastly different experiences: One child may attend preschool for 8 hours a day and be taught by a teacher with a bachelor's degree while the other child may be in preschool for only a few hours a day, under the supervision of a teacher with a 2-year degree. Why is there so much variability and are these programs meeting their potential for adequately preparing youngsters for school? In a new report in Psychological Science in the Public Interest, a journal of the Association for Psychological Science, Robert C. Pianta (University of Virginia), W.

Too Many Sisters Affect Male Sexuality
Growing up with lots of sisters makes a man less sexy. For rats, anyway. A new study published in Psychological Science, a journal of the Association for Psychological Science, finds that the sex ratio of a male rat's family when he's growing up influences both his own sexual behavior and how female rats respond to him. David Crews, a psychobiologist at the University of Texas at Austin, is interested in how early life affects behavior later. This is an area that has received a lot of attention recently, such as research showing that the position of a fetus in the uterus matters.

Friends Share Personal Details to Strengthen Relationships in United States, but Not in Japan
In the United States, friends often share intimate details of their lives and problems. However, such self-disclosure is much less common in Japan. A new study by an American researcher living in Japan finds that this may be because of the different social systems in the two countries, and in particular the extent to which there are opportunities to make new friends. "At first, it seemed strange that in Japan, people didn't open up and share a lot about themselves with each other," says Joanna Schug of Hokkaido University.

When Nukes Become Sacred
Newsweek: As America and Europe wrestle with the threat posed by Iran’s nuclear program, some policymakers have warned that imposing crippling sanctions on the mullahs’ regime would backfire, in that sanctions would cause Iranians to rally around their government in a show of solidarity against outside meddling. That isn't the half of it. According to a new analysis, offering Iran carrots rather than sticks—fuller diplomatic engagement, for instance, or help developing civilian nuclear power—to cease uranium enrichment and other proliferation activities may also be doomed.

Young Children Are Especially Trusting of Things They’re Told
Little kids believe the darnedest things. For example, that a fat man in a red suit flies through the air on a sleigh pulled by reindeer. A new study on three-year-olds, published in Psychological Science, a journal of the Association for Psychological Science, finds that they aren't just generally trusting. They're particularly trusting of things people say to them. Previous research has found that three-year-olds are a credulous bunch; they believe most things they're told, and skepticism doesn't kick in until later. Vikram K. Jaswal, of the University of Virginia, wanted to look more closely at trust in three-year-olds.
