1. What is Learning???- a relatively permanent change in behavior that results from experience.

2. Demonstration of Learning

3. Classical Conditioning
Neutral stimulus is paired with a stimulus that elicits a reflex (response) until the neutral response alone elicits a similar response.
UCS UCR
(meat powder) (salivation)
CS  CR
(buzzer) (salivation)

4. Words to Know
Generalization- in conditioned learning, when 2 or more stimuli are similar, the response to them is the same (i.e.- fire alarm and dismissal bell
Discrimination- in conditioned learning, the ability to recognize the differences between 2 similar stimuli
Extinction- the weakening of the process after the UCS has been removed
Spontaneous Recovery- the revival of an extinguished behavior after a period of nonresponding
Reflex- automatic reaction to a stimulus

5. Words to know (continued)
Acquisition- process through which a CS begins to produce a CR (i.e..- infant’s fear of doctors (needles).
Intensity-increase leads to a strengthening of a CR and speed (meat powder to meat)
Relevance- saccharin-flavored water
Biological Predisposition- snakes vs. stereos
Timing- longer the delay, weaker the CR; optimal- 1.5 seconds
exception- taste

6. Taste Aversion Studies
Sheep Study- lithium chloride
Rats and radiation- not time dependent
Ice cream Study- cancer patients

7. Conditioned Response and Drug Abuse
