Study Notes
Ivan Petrovich Pavlov
- Renowned for his research on conditioned reflexes and classical conditioning.
- Did not identify as a psychologist; focused on physiological processes.
Pavlov's Dogs - Investigation of Digestion
- Groundbreaking experiment demonstrating classical conditioning.
- Developed from research on dogs’ salivation in response to feeding.
Achievements
- Awarded the Nobel Prize in Physiology in 1904.
- Funded research by selling gastric juices from dogs.
Pavlov's Discovery
- Observed that food loss through a gastric fistula still triggered gastric fluid production.
- Showed that the stomach could respond without direct stimulation by food.
Key Terms in Classical Conditioning
- Unconditioned Stimulus (US): Naturally elicits an unconditioned response without prior learning (e.g., food).
- Unconditioned Response (UR): Reflexive reaction to the US (e.g., salivating).
- Conditioned Stimulus (CS): A previously neutral stimulus that elicits a response after learning occurs.
- Conditioned Response (CR): Response learned through association with the CS.
- Neutral Stimulus (NS): A stimulus that initially does not provoke any specific response.
Development of Conditioned Reflex
- Repeated pairing of CS and US leads to a direct relationship between CS and CR after learning.
Experimental Extinction
- Weakening of CR occurs when the CS is presented without the US over time.
Spontaneous Recovery
- The resurgence of a learned response occurs after a period of extinction.
Higher-Order Conditioning
- A strong CS can cause a neutral stimulus to become a second CS through association.
Reinforcers
- Primary Reinforcer: Naturally rewarding stimulus (e.g., food).
- Secondary Reinforcer: Becomes reinforcing after association with a primary reinforcer (e.g., praise).
Generalization and Discrimination
- Generalization: Similar stimuli can elicit the same CR as the CS.
- Discrimination: Ability to differentiate between the CS and non-significant stimuli.
Conditioning Techniques
- Optimal Interval Presentation: Present CS followed immediately by US for best results.
- Backward Conditioning: Present US before CS to demonstrate a relationship's informational context.
Cortical Mosaic
- Represents the brain's pattern of excitation and inhibition, influencing behavior at any moment.
Excitation and Inhibition
- Two primary forms of activity within the nervous system; stimuli can induce one or the other.
Major Theoretical Concepts
- Dynamic Stereotype: Automatic behaviors formed from repeated exposure to similar environments.
- Irradiation of Excitation: Activation in one brain area spreads to adjacent areas.
- Concentration: Localized excitation resulting in behavior, typically after extensive training.
Types of Conditioning Responses
- Excitatory Conditioning (CS+): Active response conditioning leading to avoidance behavior (e.g., food aversion).
- Conditioned Inhibition (CI): Results in a lack of response to a stimulus when inhibitory associations are formed.
Orienting Reflex
- Natural tendency to focus on and explore new or novel stimuli.
