Harry F. Harlow was a professor of psychology at the U niversity of W isconsin who, in the 1940s, established one of the w orld’s first laboratories for studying prim ate behavior. One day in 1949, Harlow and two colleagues gathered eight rhesus monkeys for a two-week experiment on learning. The researchers devised a sim ple mechanical puzzle like the one pictured on the next page. Solving it required three steps: pull out the vertical pin, undo the hook, and lift the hinged cover. Pretty easy for you and me, far more challenging for a thirteen-pound lab monkey.
