Study Notes
Learning
- Definition: Process of acquiring new information or behaviors through experience.
- Associative Learning: Our minds connect events that occur in sequence.
- Observational Learning: Learning by observing others.
Classical Conditioning
- A learning process that creates associations between two unrelated stimuli.
- Ivan Pavlov's Experiment:
- Unconditioned Stimulus (UCS): Triggers a reflexive response (e.g., food).
- Unconditioned Response (UCR): Natural reaction to a stimulus (e.g., salivation).
- Neutral Stimulus (NS): Does not initially elicit a response (e.g., bell).
- Conditioned Stimulus (CS): After repeated pairing with UCS, triggers a response (e.g., bell).
- Conditioned Response (CR): Learned response to a conditioned stimulus (e.g., salivation).
Classical Conditioning Processes
- Acquisition: When the CR is learned (CS presented).
- Extinction: Habituation to the CS.
- Spontaneous Recovery: Weak CR to CS after extinction.
- Generalization: Responding similarly to stimuli resembling the CS.
- Discrimination: Distinguishing between CS and similar stimuli that don't signal a UCS.
Pavlov's Legacy
- Classical conditioning adapts animals to their environment.
- Highlights objective study of learning.
Classical Conditioning in Everyday Life
- Medical treatments can trigger nausea and vomiting.
- Drug cravings are associated with drug-using contexts.
- Food cravings are influenced by classical conditioning.
Little Albert Experiment
- John Watson's Experiment (1920):
- Conditioned a baby to fear white rats by pairing them with a loud noise.
- NS: White rat
- UCS: Loud noise
- UCR: Fear/startle
- CS: White rat
- CR: Fear
- Ethical Concerns: The experiment raised ethical issues about using children as subjects in research.
Operant Conditioning
- Links voluntary behaviors with consequences to alter their frequency.
- Reinforcement: Increases the likelihood of a behavior.
- Punishment: Decreases the likelihood of a behavior.
Operant Conditioning Key Figures
- B.F. Skinner: Pioneer in operant conditioning research.
- Skinner Box: Controlled environment used to study animal behavior.
Types of Reinforcers
- Primary Reinforcers: Unlearned, satisfy biological needs.
- Secondary Reinforcers: Conditioned, gain power through association with primary reinforcers (e.g., money, tokens in Token Economy).
- Positive Reinforcers: Add a positive consequence to increase behavior.
- Negative Reinforcers: Remove something unpleasant to increase behavior.
Reinforcement Schedules
- Continuous Reinforcement: Reinforcer after every behavior, fastest learning, good for training.
- Partial Reinforcement: Reinforcer after a specific pattern, more resistant to extinction.
Partial Reinforcement Schedules
- Fixed Interval (FI): Reinforcer after a fixed time interval.
- Variable Interval (VI): Reinforcer after a random time interval.
- Fixed Ratio (FR): Reinforcer after a fixed number of responses.
- Variable Ratio (VR): Reinforcer after a random number of responses.
Punishment
- Positive Punishment: Add something unpleasant to decrease behavior.
- Negative Punishment: Remove something pleasant to decrease behavior.
Drawbacks of Physical Punishment
- Suppresses behavior, not forgotten.
- May reinforce punishing behavior by parents.
- Teaches discrimination, not general understanding.
- Teaches fear and generalization.
- May increase violence by modeling aggression.
Observational Learning
- Higher animals learn by watching and imitating others.
- Modeling: Learning specific behaviors by observing and imitating others.
Bobo Doll Experiment
- Bandura (1961): Children observed adult models interacting with a Bobo doll.
- Phase 1: Children watched either aggressive or non-aggressive models.
- Phase 2: Children were then allowed to play with the toys, including the Bobo doll.
- Results: Children who observed aggressive models were more likely to behave aggressively.
Key Findings and Applications
- Learning is a fundamental process: Animals learn through association and observation.
- Classical and operant conditioning are powerful learning tools: Used to teach, modify, and understand various behaviors.
- Observational learning has profound implications: Demonstrates how social interactions shape behavior in a variety of contexts.
