Behavior Theory In Practice, Part 4 (1965)

The film discusses the concept of operant conditioning, focusing on the establishment of behavior sequences or chains under multiple stimulus control. It differentiates between homogeneous chains, where responses have the same topography, and heterogeneous chains, which involve varied responses. The text illustrates these concepts through examples involving birds and dogs, detailing how successive responses are shaped and reinforced by discriminative stimuli (SDs). It emphasizes the importance of the order of responses and the role of conditioned reinforcers in maintaining behavior. The training of guide dogs is highlighted, showcasing the use of both reinforcement and punishment in teaching avoidance of obstacles. The overall message underscores the principles of behavior learned through operant conditioning, suggesting that it is more accurately described as trial and success learning.
