Study Notes
Classical Conditioning
- Ivan Pavlov, a Russian physiologist, founded classical conditioning while studying dogs' salivation related to digestion.
- He conditioned dogs to salivate to the sound of a bell, demonstrating involuntary responses to new stimuli.
John Watson and Little Albert
- John Watson conducted an experiment with an infant named Albert to explore fear conditioning in humans.
- Albert, initially unafraid of a white rat, was conditioned to fear it through loud noises, linking stimuli with emotional responses.
- The fear generalized to similar objects, leading to ethical concerns regarding the experiment's impact on the child.
Operant Conditioning
- Operant conditioning refers to learning through consequences of behavior, a concept established by B.F. Skinner.
- Example: Receiving a sticker as a reward for visiting the doctor exemplifies positive reinforcement in daily life.
B.F. Skinner's Experiments
- Associated with operant conditioning, Skinner's famous experiments include Skinner's Box and Project Pigeon.
- Skinner’s Box involved a rat learning to press a lever to receive food, reinforcing behavior through rewards.
- In Project Pigeon, pigeons were trained to guide missiles by pecking at targets for rewards, illustrating behavior modification.
Primary vs. Secondary Reinforcers
- Primary reinforcers are naturally rewarding (e.g., food, water, sleep) and necessary for survival.
- Secondary reinforcers derive value from their association with primary reinforcers (e.g., money can buy food).
Schedules of Reinforcement
- Fixed Ratio: A set number of responses required for reinforcement (e.g., three strikes in baseball).
- Variable Ratio: An unpredictable number of responses needed for reinforcement (e.g., gambling).
- Fixed Interval: Reinforcement delivered after a fixed time period (e.g., bi-weekly pay).
- Variable Interval: Reinforcement applied at unpredictable time intervals (e.g., surprise quizzes).
Albert Bandura and Observational Learning
- Albert Bandura demonstrated learning through observation with the Bobo doll experiment.
- Children who witnessed adults abusing a doll imitated the violence, while those who did not observe displayed no aggression.
- This experiment highlights the role of modeling in learning behaviors.
Pavlov's Classical Conditioning Experiment
- Neutral Stimulus (NS): The bell, initially eliciting no response.
- Unconditioned Stimulus (UCS): The meat, which naturally elicited salivation (Unconditioned Response).
- Conditioned Stimulus (CS): The bell became a conditioned stimulus after being paired with the meat.
- Conditioned Response (CR): Salivation in response to the bell alone after conditioning.
