2 Quotes & Sayings By Skinner
In the mid-1800s, American psychologist John B. Watson was conducting experiments with a young rhesus monkey, and discovered that his charges were indifferent to rewards. In other words, the monkeys didn't care if they got a treat for doing what they thought would be fun. They were motivated by "instrumental" rewards—those that corresponded with a direct reward—but not by "intrinsic" rewards
This is a key distinction in psychology—an important insight for those who study motivation and the biological basis of behavior.
