Operant Conditioning

  • Learning process where behavior is modified by its consequences.

    • Consequences being Reinforcement and Punishment

Reinforcement

  • Any consequence that strengthens or increases the likelihood of a behavior occurring again.


Punishment

  • Any consequence that decreases the likelihood of of that behavior occurring again.


Skinner made it a point to show that reinforcing the behavior you want will always be more successful than punishing bad behavior.

  • It generally takes more time and effort to to purposefully reinforce a behavior, but that is how good leaders lead well.


  • Key Steps

    • Shaping and Chaining

    • Reinforcement/Punishment

    • Schedules of Reinforcement


Law of Effect

  • Principle that behaviors followed by positive consequences are more likely to be repeated, and behaviors followed by negative consequences are less likely to be repeated.

    • If you are happy with an outcome, you are more likely to repeat the behavior.

Primary Reinforcer

  • A stimulus that naturally satisfies a basic biological need.

    • Food, water, sleep.

    • These things are inherently rewarding due to its ability to meet a survival need.

      • You do not need to be taught that these are rewarding.


Secondary Reinforcer

  • A stimulus that gains its reinforcing power by being associated with a primary reinforcer.

    • Becomes rewarding only after being paired with a primary reinforcer.

    • Giving a dog a treat(primary) and saying “good dog”(secondary).

      • The verbal affirmation is paired with a primary reinforcer.

    • Money is a secondary reinforcer, as it can be used to purchase primary reinforcers.

A reinforcement will ALWAYS strengthen a behavior.


Positive Reinforcement

  • Strengthens a behavior by ADDING something pleasant.


Negative Reinforcement

  • Strengthens a behavior by REMOVING something unpleasant.

Punishments will ALWAYS weaken a behavior.


Positive Punishments

  • Something unpleasant is ADDED to stop a behavior.


Negative Punishment

  • Something pleasant is REMOVED to stop a behavior.

When does reinforcement occur? How often should behavior be reinforced or punished?

  • The importance of schedules of reinforcement change the effectiveness of the reinforcement.


Continuous Reinforcement

  • Schedule where a reward is given every single time a desired behavior is exhibited.

    • Used to quickly teach new behavior


Partial Reinforcement

  • Schedule where a reward is given occasionally, not every single time.

    • Ratios or Intervals

Ratio Schedules

  • Schedules based on how many responses have occurred.


Fixed Ratio (FR)

  • Reward is given after a set number of times an action is performed.

    • The Pigeon receives a reward every 15 times they press the lever.

      • Other examples of this are sales commissions, video game rewards, etc.

    • High, steady rates of behavior change.

    • Pigeon moves faster the closer it gets to the number it needs for the reward.


Variable Ratio (VR)

  • Reward is given after a random number of times after a behavior is performed.

    • The Pigeon receives a reward after pressing the lever 5 times, then 9 times, then 3 times, etc.

      • Other examples of this are gambling (slot machines), lottery tickets, social media, etc.

    • Highest and steadiest rate of behavior change.

    • Pigeon presses the button quickly and constantly because they do not know when the reward will be arriving.

Interval Schedules

  • Schedules based on how much time has passed.


Fixed Interval (FI)

  • Reward is given after the same amount of time every time.

    • Pigeon is given food for the first lever press after 30 seconds have passed.

      • Other examples of this could be a weekly paycheck, dentist visits, etc.

    • Becomes predictable and creates a “scalloped” pattern of response.

      • Behavior increases the closer you get to the time of reinforcement.


Variable Interval (VI)

  • Reward is given at random amount of time

    • Pigeon is given food for the first lever press after 30 seconds, then 90 seconds, then 45 seconds, etc.

    • Creates a slow but steady rate of increase of behavior

    • Pigeon is given food first at two minutes, then at four, then at one, etc.


Successive Approximations

  • Reinforcing behaviors that gradually get closer to a desired target behavior.

    • Rewarding steps that progressively get closer to the final goal.


Shaping

  • Instead of waiting for the behavior to occur, ANY behavior leading to the targeted behavior is rewarded.


Chaining

  • Shaped behaviors are linked together in order to reach the targeted behavior

    • Teaching a child to walk happens in steps

      • First they crawl

      • Next, they stand

      • Finally, they walk.

Discrimination

  • The ability to distinguish between stimuli and respond  only to the discriminative stimulus.

    • A dog learning to sit when told to “sit” and not when told to “speak”.


Generalization

  • The tendency to respond in the same way to different but similar stimuli.

    • A learned response to one stimulus can also be triggered by slightly different stimuli.

    • In the Little Albert experiment, the child was conditioned to fear a rabbit, but that fear also appeared when he was shown other fluffy animals.

Instinctive Drift

  • The tendency for an animal that has been trained to perform a specific behavior to gradually revert back to its natural, instinctual behaviors.


Superstitious Behavior

  • A learned behavior that occurs when an action is accidentally reinforced, even if it has no causal relationship to the positive outcome.


Learned Helplessness

  • Psychological state where an individual believes they are powerless to change their situation. Even when opportunities arise, they will not be motivated to take action.

    • Comes from repeated exposure to uncontrollable negative events
