What is learning?
• A relatively permanent change in behavior or behavioral potential as a result of practice or experience

Pavlov’s Experiment
• Ivan Pavlov - Russian physiologist, late 1800’s
• Experiment with saliva and digestion of dogs
• Incidence of salivation hard to control - what was happening?
![Page 5: LEARNING LEARNING - KEY POINTS What is learning? How do we learn? –classical conditioning –operant conditioning –observational learning –insight learning](https://reader035.vdocuments.us/reader035/viewer/2022062716/56649e115503460f94afde62/html5/thumbnails/5.jpg)
Elements of Pavlov’s Experiment
• The reflexive, unlearned relationship existed between the food (UCS) and salivation (UCR)
• Dog associated other stimuli with food- sight of food, food dish, person feeding dog.
• Neutral stimulus became conditioned stimulus (CS)

Pavlov (cont.)
• After many pairings of the CS with the UCS, the reflexive response (UCR) occurred only in the presence of the CS
• When the UCR occurs only in the presence of the CS, it becomes a conditioned response (CR)
![Page 7: LEARNING LEARNING - KEY POINTS What is learning? How do we learn? –classical conditioning –operant conditioning –observational learning –insight learning](https://reader035.vdocuments.us/reader035/viewer/2022062716/56649e115503460f94afde62/html5/thumbnails/7.jpg)
Examples of UCS-UCR
• Loud sound (UCS) triggers startle response (UCR)
• Puff of air (UCS) triggers eye blink
• Presence of food (UCS) triggers salivation

Classical Conditioning
• Built on the relationship between and unconditioned stimulus and unconditioned response
• Classical conditioning occurs when an association is made between a previously neutral stimulus and unconditioned stimulus
![Page 9: LEARNING LEARNING - KEY POINTS What is learning? How do we learn? –classical conditioning –operant conditioning –observational learning –insight learning](https://reader035.vdocuments.us/reader035/viewer/2022062716/56649e115503460f94afde62/html5/thumbnails/9.jpg)
Important Terms
• Unconditioned stimulus - any stimulus that causes a reflex or emotional response without any learning or conditioning required
• Unconditioned response - the reflex response triggered by a stimulus w/o any learning required
![Page 10: LEARNING LEARNING - KEY POINTS What is learning? How do we learn? –classical conditioning –operant conditioning –observational learning –insight learning](https://reader035.vdocuments.us/reader035/viewer/2022062716/56649e115503460f94afde62/html5/thumbnails/10.jpg)
More Terms!
• Conditioned Stimulus (CS) - a previously neutral stimulus that, through conditioning now causes a classically conditioned response
• Conditioned Response (CR) - a learned response to a previously neutral stimulus that has been associated with the stimulus through repeated pairings

Classical Conditioning of Emotional Responses
• John Watson and Rosalie Raynor demonstrated how fear could be conditioned (1920)
• “Little Albert” - baby was taught to fear white rat• UCS (noise)- UCR (startle response)• UCS (noise) was paired with neutral stimulus (rat)• CR (startle response) occurred in the presence of
rat (CS)

Principles of Classical Conditioning
• Stimulus generalization - the occurrence of a learned response not only to the original stimuli, but also to other similar stimuli
• Stimulus discrimination - the occurrence of a learned response to a specific stimulus but not to other similar stimuli
![Page 13: LEARNING LEARNING - KEY POINTS What is learning? How do we learn? –classical conditioning –operant conditioning –observational learning –insight learning](https://reader035.vdocuments.us/reader035/viewer/2022062716/56649e115503460f94afde62/html5/thumbnails/13.jpg)
Principles (cont.)
• Extinction - a behavior is extinct when the response rate decreases or the person or animal no longer responds to the stimuli
• Spontaneous recovery - the reappearance of a previously extinguished behavior after a period of time w/o exposure to the CS

Real World Examples of Classical Conditioning
• Use of sex or other stimuli in advertising (Doritos commercial)
• CR is an emotional reaction to previously neutral stimuli (Dr. Burr and the sad story of Aramis cologne)
• Phobias• Medical Treatments• Prejudice

OPERANT CONDITIONING
• Learning is based on the consequences following behavior
• Association is made between a behavior and its consequences
• Behavior is strengthened if followed by a reinforcer and weakened if followed by a punisher
• Behavior is active and voluntary
![Page 16: LEARNING LEARNING - KEY POINTS What is learning? How do we learn? –classical conditioning –operant conditioning –observational learning –insight learning](https://reader035.vdocuments.us/reader035/viewer/2022062716/56649e115503460f94afde62/html5/thumbnails/16.jpg)
Major Behaviorists
• Thorndike: The Law of Effect: The frequency of the behavior is modified by its consequences
• B.F. Skinner: “to understand behavior, we must look at environmental stimuli and responses”.
![Page 17: LEARNING LEARNING - KEY POINTS What is learning? How do we learn? –classical conditioning –operant conditioning –observational learning –insight learning](https://reader035.vdocuments.us/reader035/viewer/2022062716/56649e115503460f94afde62/html5/thumbnails/17.jpg)
Reinforcement
• Any action or event that increases the probability that a response will be repeated
• Defined only by its effect on the behavior
• Possible reinforcers include money, food, attention, praise, stickers
![Page 18: LEARNING LEARNING - KEY POINTS What is learning? How do we learn? –classical conditioning –operant conditioning –observational learning –insight learning](https://reader035.vdocuments.us/reader035/viewer/2022062716/56649e115503460f94afde62/html5/thumbnails/18.jpg)
Punishment
• Any action or event that decreases the likelihood that a response will be repeated
• Like reinforcement, defined only by its measurable effect on the behavior
• Possible punishers include physical punishment, reprimands, loss of privilege
![Page 19: LEARNING LEARNING - KEY POINTS What is learning? How do we learn? –classical conditioning –operant conditioning –observational learning –insight learning](https://reader035.vdocuments.us/reader035/viewer/2022062716/56649e115503460f94afde62/html5/thumbnails/19.jpg)
Side Effects of Punishment
• Passive aggressiveness
• Increased aggression
• Avoidance behavior
• Modeling
• Only temporary suppression of behavior
• Learned helplessness

OPERANT CONDITIONING IN REAL LIFE
• Prejudice - can be learned through classical and operant conditioning (demeaning others can be reinforced by approval or attention), generalize one experience to a group of people
• Biofeedback - learn to control involuntary bodily processes with information about consequences
• Superstition - random behaviors are reinforced and thus strengthened

Cognitive and Social Learning
• Insight learning - Kohler and the chimps - the “AHA” experience.
• Latent learning - Tolman study of the rats in the maze: latent learning occurs in the absence of a reward and remains hidden until there is some incentive to demonstrate it

Observational Learning
• Albert Bandura and the BoBo doll study (1963)
• Four processes needed for observational learning to take place– Attention– Retention– Reproduction – Reinforcement
