VI DU — CHU DE: Operant Conditioning (Dieu kien hoa hanh vi) "The textbook defines operant conditioning as a learning process where behaviour is shaped by its consequences — rewards or punishments. The professor's first example involves teaching a dog to sit. When the dog sits, it receives a treat — a positive reinforcement — which makes sitting more likely in the future. The second example involves reducing undesired behaviour. A child who receives a privilege removed after bad behaviour learns to associate that behaviour with a negative consequence, making it less likely to repeat. Both examples illustrate how consistent consequences shape behaviour over time."
