Preschoolers Can Reflect on What They Don’t Know
Contrary to previous assumptions, researchers find that preschoolers are able to gauge the strength of their memories and make decisions based on their self-assessments.

Eye Movements May Reveal Difference Between Love and Lust
Soul singer Betty Everett once proclaimed, “If you want to know if he loves you so, it’s in his kiss.” But a study by University of Chicago researchers suggests the difference between love and lust might be in the eyes after all. Specifically, where your date looks at you could indicate whether love or lust is in the cards. The new study found that eye patterns concentrate on a stranger’s face if the viewer sees that person as a potential partner in romantic love, but the viewer gazes more at the other person’s body if he or she is feeling sexual desire. That automatic judgment can occur in as little as half a second, producing different gaze patterns.

But the news isn’t all bad when it comes to cognitive aging, according to a set of three articles in the July 2014 issue of Perspectives in Psychological Science. Plumbing the depths of the available scientific literature, the authors of the three articles show how several factors -- including motivation and crystallized knowledge -- can play important roles in supporting and maintaining cognitive function in the decades past middle age.

New Research From Psychological Science
Read about the latest research published in Psychological Science: The Moral Ties That Bind . . . Even to Out-Groups: The Interactive Effect of Moral Identity and the Binding Moral Foundations Isaac H. Smith, Karl Aquino, Spassena Koleva, and Jesse Graham Moral foundations can bind a group together, but in doing so they can also promote out-group hostility. To examine whether the adoption of binding moral foundations unavoidably leads to out-group hostility, the authors asked participants to rate the extent to which they believed torture was a justifiable technique for interrogating suspected terrorists.
