Presentation Transcript

  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

  8. Pavlov
