1. Learning How does experience affect behaviors and/or attitudes?

2. By Association!!
Our minds naturally connect events that occur in sequence.

7. Classical Conditioning
Unconditioned Stimulus (US)
A stimulus (an event) that triggers an unconditioned (involuntary) response.
Examples: food, loud noises, painful stimuli, bursts of air

8. Classical Conditioning
Unconditioned response (UR)
An unlearned response to an unconditioned stimulus.
Examples: hunger -> food, jumping ->horror flick, blinking -> flying objects near eye

9. Classical Conditioning
Conditioned stimulus (CS)
A neutral stimulus (an event) that comes to evoke a learned response due to being presented shortly before the US.
Ex: Bell ringing in high school, Fridays!!, Cologne

10. Classical Conditioning
Conditioned response (CR)
A learned response to a classically conditioned stimulus (CS)
Ex: Salivation of Pavlov’s dog just to the bell, your mouth watering when you smell warm cookies, smiling when you hear a song that reminds you of someone (or frowning…depending)

11. CC Check
Every time someone flushes a toilet in the apartment building, the shower becomes very hot and causes the person to jump back. Over time, the person begins to jump back automatically after hearing the flush, before the water temperature changes.
What is the:
UCS
UCR
Neutral Stimulus/CS
CR?

12. Acquisition
The initial stage in classical conditioning. during which association between a neutral stimulus and a US takes place.
Neutral stimulus needs to come before the US for conditioning to occur (most cases).
The time between the two stimuli should be about half a second.
Psychology 7e in Modules

13. Acquisition The CS needs to come half a second before
the US to cause acquisition.

14. Extinction
When a US (food) does not follow a CS (tone) CR (salivation) starts to decrease and at some point goes extinct.
Psychology 7e in Modules

15. Reinstatement
After a rest period an extinguished CR (salivation) spontaneously recovers and if CS (tone) persists alone becomes extinct again.

16. Stimulus Generalization
Tendency to respond to stimuli similar to CS is called generalization.
“Little Albert”
Conditioned to fear a white lab rat
Fear generalized to anything white and furry

17. Stimulus Discrimination
Discrimination is the learned ability to distinguish between a CS and other stimuli that do not signal a US.
Psychology 7e in Modules

18. Applications of Classical Conditioning
Alcoholics can be conditioned (aversively) partly reversing their positive-associations with alcohol.
A drug (plus its taste) that affects the immune response, can lead the taste to invoke the immune response through classical conditioning.

19. Operant Conditioning
Tilikum Attacks!!

20. Operant & Classical Conditioning
Classical conditioning forms associations between stimuli (CS and US).
Operant conditioning on the other hand forms association between behaviors and resulting events.

21. Operant Conditioning Cats in puzzle boxes
Time to escape decreased with practice
Thorndike’s “Law of Effect”
Responses followed by positive outcomes are repeated, whereas those followed by negative outcomes are not

22. Shaping
Operant conditioning procedure in which reinforcers guide behavior closer towards target behavior through successive approximations.
Method used in training schools
Psychology 7e in Modules

23. Types of Reinforcers
Psychology 7e in Modules

24. Primary & Secondary Reinforcers
Primary Reinforcer: Innately reinforcing stimulus like food, drink, sex (depending).
Conditioned Reinforcer: Is a learned reinforcer. It gets its reinforcing power through its association with primary reinforcer. Ex. Money, praise, good grades, awards, gold stars

25. Immediate & Delayed Reinforcers
Immediate Reinforcer: A reinforcer that occurs closely to a behavior in time. Rat gets a food pellet for a bar press.
Delayed Reinforcer: A reinforcer that is delayed in time for a certain behavior. A paycheck that comes at the end of a week.
We may be more inclined to engage in small immediate reinforcers (watching TV) than large delayed reinforcers (Getting A in a course) which requires consistent study.

26. Reinforcement Schedules
Continuous Reinforcement: Reinforcing the desired response each time it occurs.
Partial Reinforcement: Reinforcing a response only part of the time. Though results in slower acquisition in the beginning, shows greater resistance to extinction later on.
Psychology 7e in Modules

27. Ratio Schedules
Fixed-ratio schedule: Reinforces a response only after a specified number of responses e.g., like piecework pay, “I’m going to count to three.”
Variable-ratio schedule: Reinforces a response after an unpredictable number of responses. Hard to extinguish because of unpredictability, e.g., behaviors like gambling, fishing.

28. Interval Schedules
Fixed-interval schedule: Reinforces a response only after a specified time has elapsed e.g., preparing for an exam only when the exam draws close, getting a raise every year and not in between.
Variable-interval schedule: Reinforces a response at unpredictable time intervals. produces slow steady responding, e.g., pop quiz, boss checking on you

29. Punishment
Psychology 7e in Modules

30. Motivation
Intrinsic Motivation: The desire to perform a behavior for its own sake.
Extrinsic Motivation: The desire to perform a behavior due to promised rewards or threats of punishments.
How “rewarding” is it for an orca to leap in the air for [already] dead fish from a bucket?
THIS is how orca’s feed:

31. Applications of Operant Conditioning
Skinner introduced the concept of teaching machines that would shape learning in small steps and provide reinforcements for correct rewards.

33. Applications of Operant Conditioning
Reinforcers affect productivity. Many companies now enable employees to share profits and participate in company ownership.

34. Operant Conditioning & Token Economy: “Warden, I’ve been good…my cigarettes please!”
Person exchanges a token of some sort, earned for exhibiting the desired behavior, for various privileges or treats.

36. Bandura's Experiments
Bandura's Bobo doll study (1961) indicated that individuals (children) learn through imitating others who receive rewards and punishments.

37. Negative Observational Learning
Bandura’s studies show that antisocial models (family, neighborhood or TV) may have antisocial effects.

38. Positive Observational Learning
Prosocial (positive, helpful) models may have prosocial effects.

41. Latent Learning
Such cognitive maps are based on latent learning, which becomes apparent only when an incentive is given (Tolman & Honzik, 1930).

42. Biological Predisposition
Biological constraints predispose organisms to learn associations that are naturally adaptive.
Breland and Breland (1961) showed that animals drift towards their biologically predisposed instinctive behaviors.

Skinner’s Legacy
Skinner argued that behaviors were shaped by external influences instead of inner thoughts and feelings. Critics argued that Skinner dehumanized people by neglecting their free will.

44. Motivation
Motivation is a need or desire that energizes behavior and directs it towards a goal.

45. Perspectives on Motivation
Four perspectives used to explain motivation include the following:
Instinct Theory (replaced by the evolutionary perspective)
Drive-Reduction Theory
Arousal Theory
Hierarchy of Motives

46. Instincts & Evolutionary Psychology
Instincts are complex behaviors that have fixed patterns throughout different species and are not learned (Tinbergen, 1951).

the bird builds only one kind of nest.

47. Drives and Incentives
When the instinct theory of motivation failed, it was replaced by the drive-reduction theory. A physiological need creates an aroused tension state (a drive) that motivates an organism to satisfy the need.

48. Incentive
Where our needs push, incentives (positive or negative stimuli) pull us in reducing our drives.
A food-deprived person who smells baking bread
(incentive) feels a strong hunger drive.

49. Optimum Arousal
Human motivation aims to seek optimum levels of arousal, not to eliminate it. Young monkeys and children are known to explore the environment in the absence of a need-based drive.

50. A Hierarchy of Motives
Abraham Maslow (1970) suggested that certain needs have priority over others. Physiological needs like breathing, thirst, and hunger come before psychological needs such as achievement, self-esteem, and the need for recognition.

52. Hunger When do we eat? When we are hungry. When are we hungry?
When there is no food in our stomach.
How do we know when our stomach is empty?
Our stomach growls. These are also called hunger pangs.

53. The Physiology of Hunger
Stomach contractions (pangs) send signals to the brain making us aware of our hunger.

54. Stomachs Removed
Tsang (1938) removed rat stomachs, connected the esophagus to the small intestines, and the rats still felt hungry (and ate food).

55. Body Chemistry & the Brain
Levels of glucose in the blood are monitored by receptors (neurons) in the stomach, liver, and intestines. They send signals to the hypothalamus in the brain.
Rat Hypothalamus

56. Hypothalamic Centers
The lateral hypothalamus (LH) brings on hunger (stimulation). Destroy the LH, and the animal has no interest in eating. The reduction of blood glucose stimulates orexin in the LH, which leads rats to eat ravenously.

57. Hypothalamic Centers
The ventromedial hypothalamus (VMH) depresses hunger (stimulation). Destroy the VMH, and the animal eats excessively.
Richard Howard

58. Hypothalamus & Hormones
The hypothalamus monitors a number of hormones that
are related to hunger.
Hormone
Tissue
Response
Orexin increase
Hypothalamus
Increases hunger
Ghrelin increase
Stomach
Insulin increase
Pancreas
Leptin increase
Fat cells
Decreases hunger
PPY increase
Digestive tract
