How to Train a Brain: Crash Course Psychology #11
CrashCourse・11 minutes read
Ivan Pavlov's experiments on associative learning in dogs and his work on classical conditioning influenced the behaviorist school of thought in psychology, showcasing how animals can adapt to their environments through learned behaviors. B.F. Skinner furthered this concept with operant conditioning, using reinforcement principles like positive and negative reinforcement to shape behaviors, leading to controversy for focusing on external influences over internal thoughts and feelings.
Insights
- Pavlov's experiments on associative learning through classical conditioning with dogs revolutionized the understanding of how animals adapt to their environments through learned behaviors.
- B.F. Skinner's development of operant conditioning, emphasizing reinforcement principles in shaping behaviors, showcased the significant impact of external influences on behavior, sparking controversy over the neglect of internal thoughts and feelings in behaviorism.

Recent questions
What is the significance of Ivan Pavlov's experiments in psychology?
Ivan Pavlov's experiments are highly significant in psychology as they contributed to the behaviorist school of thought. His research on associative learning, particularly through classical conditioning with dogs, laid the foundation for understanding how organisms acquire new behaviors through experience. Pavlov's work highlighted the importance of external stimuli in shaping behavior and demonstrated the principles of conditioning, which have had a lasting impact on the field of psychology.
How did B.F. Skinner contribute to the concept of operant conditioning?
B.F. Skinner furthered the concept of operant conditioning by associating behaviors with consequences. His research, particularly with the Skinner Box, showcased how reinforcement principles can shape and modify behaviors. Skinner's distinction between positive and negative reinforcement, as well as his exploration of various reinforcement schedules, provided valuable insights into how behaviors are learned and maintained over time.
What is the difference between negative reinforcement and punishment in behaviorism?
Negative reinforcement in behaviorism involves removing aversive stimuli to increase desired behaviors, while punishment aims to decrease unwanted behaviors by introducing aversive consequences. The key distinction lies in the approach taken to modify behavior – negative reinforcement focuses on reinforcing a response by removing something unpleasant, whereas punishment involves applying a consequence to decrease the likelihood of a behavior occurring again.
How do reinforcement schedules impact learned behaviors according to behaviorists?
Behaviorists emphasize that reinforcement schedules, such as continuous or intermittent reinforcement, play a crucial role in shaping the strength and longevity of learned behaviors. Continuous reinforcement involves reinforcing a behavior every time it occurs, while intermittent reinforcement schedules reinforce behaviors only occasionally. These schedules influence how quickly a behavior is learned, how resistant it is to extinction, and the overall stability of the behavior over time.
Why did behaviorists like Pavlov, Watson, and Skinner face controversy in psychology?
Behaviorists like Pavlov, Watson, and Skinner faced controversy in psychology for their focus on external influences over internal thoughts and feelings in shaping behavior. Critics argued that behaviorism neglected the role of cognitive processes and subjective experiences in understanding human behavior. Despite this controversy, behaviorism has made significant contributions to psychology, particularly in the areas of learning, conditioning, and behavior modification.
