Psychology Chapter on Reinforcers

Reinforcers and Their Effectiveness

• Money, praise, and rewards serve as secondary reinforcers because they can be exchanged for primary reinforcers.
• Effectiveness of reinforcers influenced by five factors:
  • Immediacy: The sooner a reinforcer or punisher follows a response, the more effective it is.
  • Contingency: A consistent relationship between behavior and consequence enhances the effectiveness of reinforcement or punishment.
  • Magnitude: Larger or more intense reinforcers have a stronger effect on behavior.
  • Motivating Operations: Factors that change the potency of reinforcers and punishers, either establishing or abolishing their effectiveness.
  • Individual Differences: Responses to reinforcers vary among individuals, necessitating personalized behavior modification.

Reinforcement Schedules

• Continuous Reinforcement: Reinforcement occurs every time a desired behavior is exhibited, creating a clear and immediate feedback loop (e.g., receiving a cookie for every room cleaned).
• Partial/Intermittent Reinforcement: Reinforcement is provided only occasionally, making behaviors more resistant to extinction over time (e.g., earning a bonus after reaching a sales target).

Main Reinforcement Schedules

• Fixed Ratio (FR) Schedule: Reinforcement after a set number of responses (e.g., earning extra credit after answering twenty problems correctly).

Behavioral Definitions

• A behavioral definition offers a precise, measurable description of a target behavior (e.g., exercising defined as using a cardio machine for 20 minutes).
• Examples of behavioral definitions for various behaviors include:
  • Eating more fruits = consuming one piece of fruit.
  • Pleasure reading = reading five pages of a novel.
  • Using relaxation techniques = meditating for ten minutes.

Operational Definitions

• Behavioral definitions are similar to operational definitions in that both ensure clarity and consistency in measurement and observation in psychology.

Behavior Modification Plan

• Independent Variable (IV): The factor manipulated or changed.
• Dependent Variable (DV): The target behavior being measured.

Economics of Motivated Behavior

• Factors influencing motivated behavior include response costs, time, physical energy, psychological energy, and opportunity costs.

Importance of Grit

• Grit encompasses perseverance and commitment essential for achieving challenging goals, beyond just talent and opportunities.

Definition of Goals

• A goal represents a desired outcome, providing direction for how time and energy should be allocated.

Features of Goals

• Goals can vary in scope, complexity, and may require direct assessments and functional analysis to understand behaviors better.

Temptations

• Temptation comprises factors that may lead to undesired behaviors rather than desired behaviors, including people, objects, and situations.

Types of Temptations

• People: Friends may inadvertently encourage unwanted behaviors (e.g., unhealthy eating).
• Things: Objects in the environment can trigger unwanted behaviors (e.g., candy bars in the pantry).
• Situations: Certain activities can lead to problem behaviors (e.g., TV watching linked to snacking).
• Places: Specific environments, like restaurants or stadiums, may prompt unhealthy eating behaviors.

Strategies to Avoid Temptations

• Seeking support from friends, using self-instructions, recognizing and challenging justifications for giving in, and avoiding triggering situations are effective strategies.

Framework of Behavior: Stimulus-Response-Consequence (S-R-C)

• Behavior is understood through this framework:
  • Stimulus: Trigger that precedes behavior.
  • Response: The behavior itself.
  • Consequence: The outcome influencing the likelihood of behavior repetition, leading to operant conditioning.

Definition of Operant Conditioning

• Operant conditioning is the learning process where behavior likelihood is affected by the consequences that follow it.

Foundations of Operant Conditioning

• B.F. Skinner's work laid the foundation, focusing on how rewards and punishments shape behavior through experiments with animals.

Reinforcement vs. Punishment

• Reinforcement: Increases future behavior likelihood (positive adds a good consequence; negative removes a bad consequence).
• Punishment: Decreases future behavior likelihood (positive adds a bad consequence; negative removes a good consequence).

Definitions of Positive and Negative

• Positive: Refers to adding something (good or bad).
• Negative: Refers to taking away something (good or bad).

Contingencies of Behavior

• The four contingencies include:
  • Positive Reinforcement: Adding a favorable stimulus.
  • Negative Reinforcement: Removing an unfavorable stimulus.
  • Positive Punishment: Adding an unfavorable stimulus.
  • Negative Punishment: Removing a favorable stimulus.

Primary vs. Secondary Reinforcers

• Primary Reinforcers: Inherently satisfying and biologically needed (e.g., food).
• Secondary Reinforcers: Require learning and gain reinforcing properties through association with primary reinforcers.

Explore the critical aspects of reinforcement in behavior psychology. This quiz covers the factors that influence the effectiveness of reinforcers, including immediacy and contingency. Enhance your understanding of how different types of reinforcers can impact learning and behavior.
