Q

Define:

classical conditioning

A

learning that takes place when two stimuli, one conditioned and one unconditioned, are presented together to induce the same response

For example, Pavlov rang a bell when he was going to feed his dogs. The dogs would naturally salivate when food was presented to them, but over time when Pavlov rang his bell his dogs would salivate even without the presence of food.

Q

What was the premise of Ivan Pavlov’s classical conditioning experiment?

A

Dogs salivate at the sight of food because they form associations with food and events preceding eating the food. Pavlov sounded a bell right before presenting food, so the dogs would ultimately salivate at the sound of the bell.

Q 
Define in terms of Pavlov's experiment:
neutral stimulus (NS)
A

stimulus that initially does not elicit a response until it becomes CS

Pavlov’s example:

The NS is the bell because it does not produce salivation until it is paired with the food.

Example:

praise after participating in class

34
Q

negative reinforcement

A

removing an unpleasant consequence

Example:

taking an advil to relieve a headache

2) escape behavior: takes away the aversive stimulus after it has already started

37
Q

Define in terms of classical conditioning:

punishment

A

unpleasant consequence that follows a voluntary behavior, decreasing the probability the behavior will be repeated; a.k.a. positive punishment

Example:

spanking a child for misbehaving

38
Q

Define in terms of classical conditioning:

omission training

A

removing a rewarding consequence following a voluntary behavior, decreasing the probability the behavior will be repeated

Example:

taking away a child’s toy after misbehaving

state of feeling powerless to change yourself or your situation because of a prior inability to avoid an aversive event

41
Q

What are the three types of reinforcers?

A

1) primary
2) secondary
3) generalized

42
Q

Define and give an example of:

primary reinforcers

A

something that is biologically, naturally important and therefore rewarding

gold stars, tokens, points, money

44
Q

Define and give an example of:

generalized reinforcers

A

secondary reinforcer that can be associated with several primary reinforcers

Example:

money can be used to buy food and also other enjoyable items.

45
Q

How does a token economy work?

A
  • operant conditioning system
  • secondary reinforcers are used to increase acceptable behaviors
  • tokens can be exchanged for privileges and prizes
  • used in mental hospitals and jails
46
Q

Define behavior modification in terms of operant conditioning.

A
  • small steps are rewarded until the intended goal is achieved
  • uses the behavioral approach to solve individual, institutional, and societal problems
47
Q

How is shaping used to teach a new behavior?

A

positively reinforcing closer and closer approximations of the desired behavior

Example:

In toilet training, rewards are given to the child at each step.

48
Q

Define chaining as it relates to operant conditioning.

A
  • initially positively reinforcing each behavior in a certain order
  • later on, rewards only given for completing the whole sequence
  • in order to establish a specific sequence of behaviors
49
Q

What is the purpose of reinforcement schedules?

A

to determine how and when reinforcers will be given to the learner

50
Q

What is a continuous reinforcement schedule?

A

provides reinforcement every time the behavior is exhibited by human or animal

51
Q

What is a partial reinforcement schedule?

A
  • reinforcing behavior only some of the time

- a.k.a. intermittent schedule

52
Q

What is a Partial Reinforcement Schedules schedule and what are the four types?

A

schedule based on the number of desired responses

fixed ratio
fixed interval
variable ratio
variable interval

53
Q

Define:

fixed ratio schedule

A

reinforcement comes after a specific number of behavior responses

Example:

Every three times you get a question right, you get a piece of candy.

54
Q

Define:

fixed interval schedule

A

reinforcement comes at a specific time

Example:

You know you have a quiz tomorrow, so you don’t study until the night before.

55
Q

Define:

variable ratio schedule

A

number of behavior responses needed for reinforcement changes

Example:

You sit at a slot machine pulling the lever hundreds of time because you don’t know how many pulls are needed before the jackpot.

56
Q

Define:

variable interval schedule

A

amount of time before reinforcement of behavior changes

Example:

You study every night in preparation for a pop quiz because you don’t know when it is coming.

57
Q

How is superstitious behavior formed?

A

When reinforcement occurs during an idiosyncratic behavior, the organism is likely to repeat that behavior, even though it doesn’t cause the reinforcement.

58
Q

What did John B. Watson and B.F. Skinner study?

A

studied only behaviors, disregarded thought processes because they were not observable

59
Q

What do cognitive theorists believe humans and other animals are capable of, beyond classical and operant conditioning?

A

forming expectations and being consciously motivated by rewards

60
Q

What is the contingency model?

A

Richard Rescorla’s theory that the key to classical conditioning is how well the CS predicts the appearance of the UCS

61
Q

What model did the contingency model counter?

A

Pavlov’s contiguity model that classical conditioning is based on the association in time of the CS prior to the UCS

62
Q

What is the blocking effect?

A

Leon Kamin’s concept that conditioning effect of neutral stimulus is blocked when already conditioned with UCS. In other words, once CS and UCS are paired, a second CS will not result in the same CR that the UCS received. The second CS is blocked because an association already exists between the first CS and the UCS.

63
Q

Name an example of delayed gratification.

A

saving money for college or a car, rather than spending it immediately

64
Q

Who was Edward Tolman?

A
  • confirmed the presence of latent learning

65
Q

Define:

latent learning

A

learning in the absence of rewards

66
Q

Define insight as it relates to learning.

A

sudden appearance of an answer or solution to a problem

69
Q

What are the four steps of observational learning, according to Albert Bandura?

70
Q

What were the results of the bobo dolls experiment?

A
  • when offered rewards to imitate violent behavior, did not always lead to response
  • demonstrated modeling: those who watched violent models imitated them
71
Q

What provides the biological basis for observational learning?

A

Mirror neurons are activated when you perform an action and when you observe someone else perform a similar action.

72
Q

Define:

conditioned taste aversion

A
  • intense dislike and avoidance of a food because of its association with an unpleasant or painful stimulus through backward conditioning
  • adaptive responses of organisms to foods that could sicken or kill them
  • a.k.a. Garcia effect
73
Q

Define preparedness as it relates to learning.

A

Through evolution, animals are biologically predisposed to easily learn behaviors related to their survival as a species.

74
Q

Who experimented on conditioned taste aversions and biological preparedness in rats?

A

John Garcia and Robert Koelling

75
Q

What is instinctive drift?

A

CR that drifts back toward the natural, instinctive behavior of the organism
