When My Eyes Serve My Stomach
Our senses aren’t just delivering a strict view of what’s going on in the world; they’re affected by what’s going on in our heads. A new study finds that hungry people see food-related words more clearly than people who’ve just eaten. The study, published in Psychological Science, a journal of the Association for Psychological Science, finds that this change in vision happens at the earliest, perceptual stages, before higher parts of the brain have a chance to change the messages coming from the eyes. Psychologists have known for decades that what’s going on inside our head affects our senses.

Who’s in the Know? To a Preschooler, the Person Doing the Pointing
If you want a preschooler to get the point, point. That’s a lesson that can be drawn from a new study in Psychological Science, a journal published by the Association for Psychological Science. As part of their investigation of how small children know what other people know, the authors, Carolyn Palmquist and Vikram K. Jaswal of the University of Virginia, found they were able to mislead preschoolers with the simple introduction of a pointing gesture. “Children were willing to attribute knowledge to a person solely based on the gesture they used to convey the information,” says Palmquist.

The Ever-Expanding Definition of “Diversity”
Diversity has become a goal for all sorts of institutions—but what it means may depend on who you ask. A new study published in Psychological Science, a journal of the Association for Psychological Science, finds that people’s ideologies help determine what they count as “diverse.” Miguel Unzueta, the study’s lead author, notes that “diversity” historically meant inclusiveness toward historically disadvantaged groups. Now, however, the term is commonly used to refer to people who are different in any way (even personality traits and food preferences)—and that, Dr. Unzueta argues, may be making the concept useless. Dr.

Stress Changes How People Make Decisions
Trying to make a big decision while you’re also preparing for a scary presentation? You might want to hold off on that. Feeling stressed changes how people weigh risk and reward. A new article published in Current Directions in Psychological Science, a journal of the Association for Psychological Science, reviews how, under stress, people pay more attention to the upside of a possible outcome. It’s a bit surprising that stress makes people focus on the way things could go right, says Mara Mather of the University of Southern California, who cowrote the new review paper with Nichole R. Lighthall. “This is sort of not what people would think right off the bat,” Mather says.

Preschools Get Disadvantaged Children Ready for the Rigors of Kindergarten
Preschools help children prepare for the rigors of grade school—especially children who come from a minority family, a poor family, or whose parents don’t provide high-quality interactions. The results of a new study of over 1,000 identical and fraternal twins, published in Psychological Science, a journal of the Association for Psychological Science, confirm that preschool programs are a good idea. Of course, many children from poor families excel in school. But it’s no secret that many do not. People used to think this had to do with the lower-quality schools in poor neighborhoods, but it has become clear that many poor children start first day of kindergarten playing catch-up.

Girls’ Verbal Skills Make Them Better At Arithmetic
While boys generally do better than girls in science and math, some studies have found that girls do better in arithmetic. A new study published in Psychological Science, a journal of the Association for Psychological Science, finds that the advantage comes from girls’ superior verbal skills. “People have always thought that males’ advantage is in math and spatial skills, and girls’ advantage is in language,” says Xinlin Zhou of Beijing Normal University, who cowrote the study with Wei Wei, Hao Lu, Hui Zhao, and Qi Dong of Beijing Normal University and Chuansheng Chen of the University of California-Irvine.
