Punishment and Reinforcement

• Basic Concepts

  • Reinforcement: Increases the likelihood of a behavior.

  • Punishment: Decreases the likelihood of a behavior.

  • Example: Saying "good job" reinforces positive behavior, while criticism discourages it.

Behavioral Examples

• Delayed Gratification:

  • Concept of delayed discounting: weighing immediate versus future rewards.

  • E.g., choosing between $1 now or $2 next week.

  • This highlights willingness to forgo smaller rewards for potentially greater gains.

Behavioral Conditioning in Dogs

• **Learning Strategies:

  • Use of positive reinforcement for behaviors (e.g., teaching a dog to sit):

    • Reward incremental behaviors that lead to the desired outcome.

    • Recognize and reward any attempts that approximate the desired action.

• Successive Approximations:

  • Gradually expect closer approximations of the final behavior before reinforcing.

  • Involves patience and consistency, using timing and frequency of rewards effectively.

Principles of Reinforcement

• Timing:

  • Immediate rewards are more effective than delayed ones—reward after the behavior occurs, not later.

• Frequency of Reward:

  • The more often you reinforce a behavior, the stronger that behavior becomes and resistant to extinction.

Behavioral Expectations and Phenomena

• Near Miss Phenomenon:

  • Instances where individuals feel close to achieving a reward can lead to persistent behaviors (e.g., slot machines).

  • Examples include gamblers who continue playing despite losses due to perceived near wins.

Gambling Behavior

• Common Behaviors in Gamblers:

  • Individuals may have irrational methods for selecting lottery or gambling tickets, often believing in luck or patterns.

  • Significant frequencies of buying and scratching tickets demonstrate commitment despite odds.

Partial Reinforcement Schedules

• Types of Schedules:

  • Fixed Ratio:

    • Reinforcement provided after a set number of responses (e.g., reward after every 5 correct actions).

  • Variable Ratio:

    • Reinforcement after an unpredictable number of responses (common in gambling).

  • Fixed Interval:

    • Reinforcement after a set period (e.g., paychecks).

  • Variable Interval:

    • Reinforcement after varying intervals of time.

Final Notes

• Manipulating frequency and time can sustain high response rates in behavior learning.

• Understanding the nuances of reinforcement and behavior shaping can lead to better training and behavior modification.
