Roots of altruism show in babies' helping hands
By Lauran Neergaard, The Associated Press
WASHINGTON — Oops, the scientist dropped his clothespin. Not to worry — a wobbly toddler raced to help, eagerly handing it back. The simple experiment shows the capacity for altruism emerges as early as 18 months of age.
Toddlers' endearing desire to help out actually signals fairly sophisticated brain development, and is a trait of interest to anthropologists trying to tease out the evolutionary roots of altruism and cooperation.
Psychology researcher Felix Warneken performed a series of ordinary tasks in front of toddlers, such as hanging towels with clothespins or stacking books. Sometimes he "struggled" with the tasks; sometimes he deliberately messed up.
Over and over, whether Warneken dropped clothespins or knocked over his books, each of 24 toddlers offered help within seconds — but only if he appeared to need it. Video shows how one overall-clad baby glanced between Warneken's face and the dropped clothespin before quickly crawling over, grabbing the object, pushing up to his feet and eagerly handing back the pin.
