Final answer:
Operant conditioning involves trial-and-error learning, where organisms learn to associate a behavior and its consequences.
Step-by-step explanation:
Operant conditioning, associated with BF Skinner, involves trial-and-error learning. In operant conditioning, organisms learn to associate a behavior and its consequence. A pleasant consequence makes that behavior more likely to be repeated in the future. For example, a dolphin at the National Aquarium in Baltimore does a flip in the air when her trainer blows a whistle, and she gets a fish as a consequence.
