WEBVTT 1 00:00:04.500 --> 00:00:08.200 We have all seen animals performing tricks. 2 00:00:08.200 --> 00:00:15.500 These animals are trained using operant conditioning as described by B. F. Skinner. 3 00:00:15.500 --> 00:00:22.800 But it is a long way from a rat pressing a bar, as Skinner and many others have done in the lab, 4 00:00:22.800 --> 00:00:27.500 to animals performing elaborate tricks outside of the lab. 5 00:00:27.500 --> 00:00:32.500 The difference is in the number of steps to condition the behavior 6 00:00:32.500 --> 00:00:39.000 and it relies on the process called shaping which we will explore in this activity.
