1. What is learning? What are the 3 types of learning discussed in class? How does each explain learning–what are the processes of each type? Give examples of each learning type.

Learning is the process by which individuals acquire new knowledge, behaviors, skills, values, or preferences through experience, study, or teaching. The three types of learning typically discussed in psychology are:

• Classical Conditioning: Learning occurs through association, where an organism learns to associate a neutral stimulus with a stimulus that elicits an automatic response.

Example: Pavlov’s dogs learned to salivate when they heard a bell, after associating the bell with the presentation of food.

• Operant Conditioning: Learning occurs through consequences, where behaviors are influenced by reinforcements or punishments.

Example: A child gets a reward for doing homework, increasing the likelihood they will complete it in the future.

• Observational Learning (Social Learning): Learning occurs by observing and imitating others.

Example: A child learns how to tie their shoes by watching a parent do it.

2. What is classical conditioning? Who discovered it and how was it discovered? What are the key concepts of it? What are the procedures involved in it? Understand the differences between UCS, UCR, CS, & CR. Give examples.

Classical conditioning is a type of learning where a neutral stimulus becomes associated with a meaningful stimulus, eliciting a similar response.

• Discovery: Ivan Pavlov discovered classical conditioning in the early 1900s. His famous experiment involved dogs, where he paired the sound of a bell (neutral stimulus) with the presentation of food (unconditioned stimulus), eventually causing the dogs to salivate at the sound of the bell alone.

• Key Concepts:

• Unconditioned Stimulus (UCS): A stimulus that naturally triggers a response (e.g., food).

• Unconditioned Response (UCR): An automatic, natural response to the UCS (e.g., salivation).

• Conditioned Stimulus (CS): A previously neutral stimulus that, after association with the UCS, triggers a similar response (e.g., bell).

• Conditioned Response (CR): The learned response to the CS (e.g., salivation when hearing the bell).

• Example: In Pavlov’s experiment, the food was the UCS, salivation was the UCR, the bell was the CS, and salivation in response to the bell was the CR.

3. How is taste aversion different from higher order conditioning? And how are these two different from the basic classical conditioning? Give examples.

• Taste Aversion: A form of classical conditioning that occurs when an individual associates a particular taste with an unpleasant experience, leading to a strong aversion to that taste. It is unique because it can occur after just one pairing of the taste with the negative experience (e.g., illness).

• Example: If a person eats seafood and then gets food poisoning, they might develop a strong aversion to seafood, even if they enjoyed it previously.

• Higher-Order Conditioning: Occurs when a neutral stimulus is paired with an already established conditioned stimulus, leading the neutral stimulus to become a conditioned stimulus on its own.

• Example: If a dog has learned to salivate to the sound of a bell (CS), and then the bell is paired with a light, the dog may begin to salivate to the light alone, even though it never had a direct association with food.

4. What is the law of effect and who came up with it? How is the law of effect relating to operant conditioning?

• Law of Effect: Proposed by Edward Thorndike, this law states that behaviors followed by satisfying consequences are more likely to be repeated, while behaviors followed by unpleasant consequences are less likely to be repeated.

• Relation to Operant Conditioning: The law of effect laid the foundation for B.F. Skinner’s operant conditioning, which involves reinforcing or punishing behavior to increase or decrease the likelihood of its occurrence.

5. Compare and contrast the differences between classical conditioning and operant conditioning.

• Classical Conditioning: Involves associating two stimuli to elicit a response (e.g., Pavlov’s dogs).

• Operant Conditioning: Involves associating a behavior with a consequence (reinforcement or punishment) to increase or decrease the likelihood of that behavior (e.g., Skinner’s box).

6. Explain why these individuals are important figures in psychology: Ivan Pavlov, Robert Rescorla, Edward Thorndike, B.F. Skinner, John Watson, and Albert Bandura.

• Ivan Pavlov: Discovered classical conditioning through his work with dogs, showing how associations between stimuli could lead to learned responses.

• Robert Rescorla: Advanced classical conditioning by demonstrating that the strength of the association between the conditioned stimulus and the unconditioned stimulus depends on the predictability of the unconditioned stimulus.

• Edward Thorndike: Developed the law of effect, which influenced the development of operant conditioning.

• B.F. Skinner: Pioneered operant conditioning, showing how reinforcement and punishment can shape behavior.

• John Watson: Established the behaviorist perspective in psychology, demonstrating that emotions and behaviors can be conditioned.

• Albert Bandura: Known for his social learning theory, demonstrating the importance of observing and imitating others (e.g., Bobo doll study).

7. What is the difference between primary reinforcer and secondary reinforcer? What are some types of secondary reinforcers and how do they differ? Give examples.

• Primary Reinforcer: A stimulus that is naturally reinforcing because it satisfies biological needs (e.g., food, water).

• Secondary Reinforcer: A stimulus that gains reinforcing power through its association with a primary reinforcer (e.g., money, grades).

• Example of secondary reinforcer: A teacher praising a student with a gold star, which becomes reinforcing due to the student associating it with rewards.

8. How do the two types of desirable consequences (positive and negative) differ from each other? And the two types of undesirable consequences (positive and negative)? Provide examples of each.

• Positive Reinforcement: Adding a pleasant stimulus to increase behavior (e.g., giving a treat for doing homework).

• Negative Reinforcement: Removing an unpleasant stimulus to increase behavior (e.g., stopping nagging once a child finishes chores).

• Positive Punishment: Adding an unpleasant stimulus to decrease behavior (e.g., giving extra chores for misbehavior).

• Negative Punishment: Removing a pleasant stimulus to decrease behavior (e.g., taking away a child’s toy for hitting).

9. What are some differences between continuous reinforcement and partial reinforcement? What are the four types of partial schedules of reinforcement? What is the benefit to partial reinforcement? Provide examples of each.

• Continuous Reinforcement: Reinforcing a behavior every time it occurs (e.g., giving a dog a treat every time it sits).

• Partial Reinforcement: Reinforcing a behavior only some of the time.

• Four Types of Partial Reinforcement:

1. Fixed-Ratio: Reinforcement after a specific number of behaviors (e.g., giving a reward after every 5 tasks).

2. Variable-Ratio: Reinforcement after an unpredictable number of behaviors (e.g., gambling).

3. Fixed-Interval: Reinforcement after a fixed amount of time (e.g., weekly paycheck).

4. Variable-Interval: Reinforcement after an unpredictable amount of time (e.g., checking for a text message).

• Benefit: Partial reinforcement makes behavior more resistant to extinction.

10. What are some factors involved in social learning? Who is associated with the Bobo doll study? What are the findings of the study? Provide examples.

• Factors in Social Learning: Attention, retention, reproduction, and motivation.

• Bobo Doll Study: Conducted by Albert Bandura, it demonstrated that children could learn aggressive behaviors by observing adults. The study showed that children imitated aggressive actions when they saw an adult model doing the same.

11. What are mirror neurons? Why are they important? How do they help us understand social learning?

Mirror neurons are brain cells that fire both when an individual performs an action and when they observe someone else perform the same action. They are important for understanding empathy, imitation, and learning through observation, providing a biological basis for social learning.
