Questions and Answers

What is operant conditioning and who is it named after?

Operant conditioning is a learning method that uses rewards and punishments to influence behavior, named after B.F. Skinner.

Give an example of operant conditioning in action.

An example is lab rats pressing a lever for food when the green light is on and avoiding it when the red light is on due to receiving a shock.

How does operant conditioning impact everyday behavior?

Operant conditioning influences behavior by reinforcing actions that yield positive outcomes and discouraging those with negative consequences.

Study Notes

Operant Conditioning

  • Operant conditioning is a learning method using rewards and punishments to modify behavior.
  • It associates a behavior with a consequence (positive or negative).
  • Lab experiments (e.g., rats pressing levers for food or avoiding shocks) demonstrate operant conditioning.
  • Operant conditioning impacts everyday learning, from classrooms to therapy sessions.

History of Operant Conditioning

  • B.F. Skinner described operant conditioning, also known as Skinnerian conditioning.
  • Skinner focused on observable external causes of behavior, rejecting internal thoughts/motivations.
  • Early behaviorism, influenced by John B. Watson, focused on classical conditioning.
  • Skinner's work was influenced by Edward Thorndike's "law of effect": desirable outcomes increase behavior; undesirable outcomes decrease it.
  • Operant behavior is an active action affecting the environment to create consequences.

How Operant Conditioning Works

  • Reinforcement strengthens behavior; punishment weakens it.
  • Positive reinforcement: Adding a desirable event to increase the behavior.
  • Negative reinforcement: Removing an undesirable event to increase behavior.
  • Positive punishment: Adding an undesirable event to decrease a behavior.
  • Negative punishment: Removing a desirable event to decrease a behavior.

Respondent vs. Operant Behaviors

  • Respondent behaviors are automatic/reflexive (e.g., pulling back from a hot stove).
  • Operant behaviors are under conscious control (e.g., studying to get a good grade).

Skinner's Methods

  • Skinner Box (operant conditioning chamber): housed small animals to study operant conditioning with levers for rewards.
  • Cumulative recorder: tracked responses visually.

Reinforcement Schedules

  • Continuous reinforcement: reinforcement every time; quick learning, fast extinction.
  • Partial reinforcement: reinforcement sometimes; slower learning, slower extinction.
    • Fixed-ratio: reinforcement after a set number of responses.
    • Fixed-interval: reinforcement after a set time interval.
    • Variable-ratio: reinforcement after a varying number of responses.
    • Variable-interval: reinforcement after a varying time interval.

Examples of Operant Conditioning

  • Children completing homework for rewards.
  • Employees receiving praise or promotions for finishing projects.
  • Receiving applause for a performance.
  • Training a dog to fetch.
  • Avoiding class disruption after a punishment
  • Removing privileges for misbehavior.

Takeaways

  • Operant conditioning persists as a behavior modification tool despite earlier behaviorism's decline.
  • It influences both everyday interactions and structured settings (e.g., education, training).
  • Reinforcement schedules and types of reinforcement need to be considered for the desired outcome.
