Getting Kids to Eat More Vegetables
If you want a child to eat more vegetables, it might help to use plates illustrated with pictures of vegetables. Researchers tested 235 preschoolers in day care centers. At lunchtime, they gave half the children a segmented plate with pictures of fruits and vegetables in the compartments. They explained that the pictures indicated where the foods were to be placed. The other half used plain white plates. After three days, they switched plates — the first group got the plain plates, the second those with illustrations. The children served themselves from serving bowls and ate as much as they wanted.

You 2.0: Dream Jobs
Why do you work? Popular wisdom says your answer depends on what your job is. But psychologist Amy Wrzesniewski at Yale University finds it may have more to do with how we think about our work. Across a diverse array of jobs — from secretaries to custodians to computer programmers — Wrzesniewski finds people are about equally split in whether they say they have a "job," a "career," or a "calling." This week on Hidden Brain, Shankar Vedantam talks with Wrzesniewski about how we find meaning and purpose at work. This episode is part of our "You 2.0" summer series. Each story looks at how we can improve the decisions we make, from the mundane to the momentous.

Can the Psychological Technique of ‘Pre-Conformity’ Help Change Our Harmful Behaviors?
Psychologists have found a simple trick to reduce meat consumption in restaurants. Tell a customer that other people are increasingly choosing the menu's meatless options, and the customer becomes more likely to order a vegetarian meal. It's a simple but effective intervention that relies on peer pressure and social influence to convince people to rethink their longstanding habits, says Gregg Sparkman, a Ph.D. student in psychology at Stanford University who led the experiment. Essentially, Sparkman's findings show that you can change a person's behavior by highlighting other people's success in changing their behaviors.

There’s No Innocent Way to Ask Your Son or Daughter About Grandkids
This summer, my family has been spending a month at the beach. It’s been like a daydream come to life: bright days and languid evenings spent with family, including a sparkly 3-year-old and her serene new baby sister. My granddaughters. I started picturing—and pining for—this kind of family gathering, the three-generation kind that includes grandchildren, as my 60s loomed and my two daughters entered their 30s with no obvious plans for baby-making. I’d kept to a pretty brisk schedule when I became a mother; I had both of my girls before I turned 30.

You 2.0: When Did Marriage Become So Hard?
Marriage is hard. In fact, there's evidence it's getting even harder. Eli Finkel, a social psychologist at Northwestern University, argues that's because our expectations of marriage have increased dramatically in recent decades. "[A] marriage that would have been acceptable to us in the 1950s is a disappointment to us today because of those high expectations," he says. The flip side of that disappointment, of course, is a marriage that's pretty amazing.
