Basic Learning Concepts and Classical Conditioning

2. Basic Learning Concepts and Classical Conditioning How Do We Learn?
19-1: WHAT IS LEARNING, AND WHAT ARE SOME BASIC FORMS OF LEARNING?
Learning: Process of acquiring through experience new and relatively enduring information or behaviors
One way we learn is by association.
Associative learning : Learning that certain events occur together. The events may be two stimuli (as in classical conditioning) or a response and its consequences (as in operant conditioning).

3. Basic Learning Concepts and Classical Conditioning How Do We Learn?
A stimulus is an event or situation that evokes a response.
The process of learning associations is conditioning, which takes two main forms:
In classical conditioning, we associate stimuli that we do not control, and we automatically respond (exhibiting respondent behaviors).
In operant conditioning, we associate a response (our behavior) and its consequence (producing operant behaviors).
Conditioning, this process of learning associations, is not the only form of learning: cognitive learning is another.
Cognitive learning: The acquisition of mental information, whether by observing events, by watching others, or through language.
Observational learning is one form of cognitive learning. It lets us learn from others’ experiences.

19-2: WHAT WAS BEHAVIORISM’S VIEW OF LEARNING?
Ivan Pavlov’s early twentieth-century experiments are psychology’s most famous research.
Classical conditioning: Type of learning in which one learns to link two or more stimuli and anticipate events.
Behaviorism
Psychology (1) should be an objective science that (2) studies behavior without reference to mental processes.
Most research psychologists today agree with (1) but not with (2).

5. Basic Learning Concepts and Classical Conditioning Classical Conditioning: Pavlov’s Experiments
19-3: WHO WAS PAVLOV, AND WHAT ARE THE BASIC COMPONENTS OF CLASSICAL CONDITIONING?
Pavlov
Studied the digestive system; first Russian Nobel Prize (1904 )
Demonstrated associative learning via salivary conditioning
PAVLOV’S DEVICE FOR RECORDING SALIVATION
A tube in the dog’s cheek collects saliva, which is measured in a cylinder outside the chamber.

6. Basic Learning Concepts and Classical Conditioning Classical Conditioning: Pavlov’s Experiments
Neutral stimulus (NS): In classical conditioning, a stimulus that elicits no response before conditioning
Unconditioned response (UR): In classical conditioning, an unlearned, naturally occurring response (such as salivation) to an unconditioned stimulus (US) (such as food in the mouth)
Unconditioned stimulus (US): In classical conditioning, a stimulus that unconditionally—naturally and automatically—triggers an unconditioned response (UR)

7. Basic Learning Concepts and Classical Conditioning Classical Conditioning: Pavlov’s Experiments
Conditioned response (CR): In classical conditioning, a learned response to a previously neutral (but now conditioned) stimulus (CS)
Conditioned stimulus (CS): In classical conditioning, an originally irrelevant stimulus, that, after association with an unconditioned stimulus (US), comes to trigger a conditioned response (CR)
For three decades, Pavlov’s research demonstrated associative learning, exploring five major conditioning processes (acquisition, extinction, spontaneous recovery, generalization, and discrimination)

19-4: IN CLASSICAL CONDITIONING, WHAT ARE THE PROCESSES OF ACQUISITION, EXTINCTION, SPONTANEOUS RECOVERY, GENERALIZATION, AND DISCRIMINATION?
Acquisition
Initial stage, when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response
Extinction
Diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (US) does not follow a conditioned stimulus (CS)
Spontaneous recovery
Reappearance, after a pause, of an extinguished conditioned response

9. Idealized Curve of Acquisition, Extinction, and Spontaneous Recovery
The rising curve shows the CR rapidly growing stronger as the NS becomes a CS due to repeated pairing with the US (acquisition). The CR then weakens rapidly as the CS is presented
alone (extinction). After a pause, the (weakened) CR reappears (spontaneous recovery).

10. Basic Learning Concepts and Classical Conditioning Classical Conditioning: Acquisition
Generalization
Tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses
Discrimination
Learned ability to distinguish between a conditioned stimulus (which predicts the US) and other irrelevant stimuli

11. Generalization
Pavlov demonstrated generalization by attaching miniature vibrators to various parts of a dog’s body.
After conditioning salivation to stimulation of the thigh, he stimulated other areas.
The closer a stimulated spot was to the dog’s thigh, the stronger the conditioned response. (From Pavlov, 1927.)

12. Basic Learning Concepts and Classical Conditioning Classical Conditioning: Pavlov’s Legacy
19-5: WHY DOES PAVLOV’S WORK REMAIN SO IMPORTANT?
Consensus among psychologists that classical conditioning is a basic form of learning.
Why should we care that dogs can be conditioned to the sound of a tone? Many other responses to many other stimuli can be classically conditioned in many other organisms.
Pavlov demonstrated how a learning process can be studied objectively.
Classical conditioning is a basic form of learning that applies to all species.

19-6: WHAT HAVE BEEN SOME APPLICATIONS OF PAVLOV’S WORK TO HUMAN HEALTH AND WELL-BEING? HOW DID WATSON APPLY PAVLOV’S PRINCIPLES TO LEARNED FEARS?
Pavlov’s principles are used to influence human health and well-being
Areas of consciousness, motivation, emotion, health, psychological disorders, therapy
Addicts counseled to avoid stimuli (for example, people and settings) that may trigger cravings
Pairing particular taste with drug that influences immune responses may eventually lead to immune response from taste alone

14. Basic Learning Concepts and Classical Conditioning Classical Conditioning: Applications of Classical Conditioning
Pavlov’s work also provided a basis for Watson’s ideas that human emotions and behaviors, though biologically influenced, are mainly a bundle of conditioned responses.
Watson applied classical conditioning principles in his studies of “Little Albert” to demonstrate how specific fears might be conditioned.
Watson boasted that he could take any healthy infant and train for any career specialization, regardless of any inborn traits, but later admitted to “going beyond his facts.”
