25
What is conditioned taste aversion?
(one trial) when getting sick paired with a food or drink leads to feeling nauseous in the presence of the same food/drink later
26
Who was John B. Watson?
a behaviorist that experimented with observable behavior and conditioned responses (with Little Albert)
27
What was the "Little Albert" experiment?
a rat was placed in front of Albert and originally he showed no fear towards the rat, but the scientists rang a loud bell when Albert was with the rat causing Albert to be startled and crying (they repeated this several times) and now Albert started crying every time he was presented with a rat (even if the bell wasn't rung)
28
What happened to Albert after the experiment?
he started to portray stimulus generalization and became fearful of rabbits, a dug, fur coats (things that looked similar to the white rat)
29
What is operant conditioning?
voluntary behavior comes to be controlled by consequences following its occurrence (using rewards and punishments to modify behavior)
30
What is the Law of Effect?
behaviors producing pleasant consequences are likely to be repeated in similar situations and behaviors producing negative consequences are less likely to be repeated
31
Who was Edward Thorndike and what did he do?
he was a psychologist that worked with cats and he constructed a puzzle box in which cats where put inside with a lock that could only be opened from the inside. he put a bowl of food outside the box and measured how long it took the cat (through trial and error) to get out of the box (when he did repeated trials he noticed that the cats became faster and faster at getting out)
32
What is trial and success learning?
learning from repeated trials and successes (rather than failures)
33
Who was BF Skinner?
psychologist that designed equipment and methods to control and measure behavior more effectively than ever before
34
What is an operant chamber?
enclosure that allows for an a precise recording of an animals responses to specific consequences that can be systematically manipulated
35
What is a discriminative stimulus?
signals when to emit a particular behavior in order to obtain a certain outcome or consequence
36
What are reinforcers?
consequences that make a behavior more likely to occur in a given situation (essentially motivation for behavior)
37
What is positive reinforcement?
the frequency, intensity, and/or duration of a behavior increases because its occurrence results in the presentation of a desirable consequence
38
What is a positive reinforcer?
any consequence that maintains or increases the behavior it follows
39
What is negative reinforcement?
strengthening of a response or behavior by stopping, removing, or avoiding a negative outcome or aversive stimulus
40
What are primary reinforces?
reinforces which are biologically based or necessary for survival (food, water, etc)
41
What are secondary reinforcers?
things that become reinforced through learning (and are associated with primary reinforcers)
42
What is an example of a secondary reinforcer
money, it has no value in itself but can be exchanged for things we desire such as food, clothes, etc
43
What is schedules of reinforcement?
the timing and/or frequency of reinforcer delivery following a behavior
44
What is continuous reinforcement?
each time a target behavior is performed, a reinforcing consequence is applied
45
What is an example of continuous reinforcement?
giving a dog a treat every time he/she gives out their paw
46
What is continuous reinforcement great for?
establishing a new behavior
47
What is partial or intermittent reinforcement?
a reinforcing consequence is not applied each time a target behavior is exuded
48
What is an example of partial reinforcement?
giving a dog a treat once in a while, when they give their paw
49
When is partial reinforcement most effective?
when a behavior has been established and so the behavior is less likely to disappear
50
What is a post-reinforcement pause?
the amount of time that passes after a behavior us reinforced and before the same behavior recurs
51
What is a fixed interval schedule?
schedule where a reinforcer is only available after a certain amount of time has passed
52
What is an example of a fixed interval schedule?
checking for the mail only after 5pm because there is no reinforcer (mail) before 5pm
53
What kind of graph does a fixed interval schedule make?
scalloped
54
What kind of extinction does interval schedules promote?
quick extinction when reinforcement is discontinued
55
What is a variable interval schedule?
a reinforcer is available after varying amounts of time (intervals) have passed, regardless of how often a behavior is performed
56
What is an example of a variable interval schedule?
pop quizzes, you never know when these happen so you are continuously studying, and those who pay attention and study are reinforced with an "A"
57
What is a fixed ratio schedule of reinforcement?
a behavior must be performed a certain (fixed) number of times before it is reinforced
58
What rate of behavior is exhibited by a fixed ratio schedule?
high and steady rate of behavior
59
What is an example of a fixed ratio schedule?
piece work, where a worker gets paid based on how many products produced. if the number is 25 products, then the workers will produce 25 products and take a short break
60
What is variable ratio schedule of reinforcement?
a reinforcement is only applied after a variable number of responses
61
What is an example of variable ratio schedule of reinforcement?
continually buying lottery tickets in hopes of winning (the more lotto tickets, the more of a chance to win)
62
What is positive punishment?
frequency, intensity, and/or duration of a behavior decreases because its occurrence results in the presentation of an undesirable consequence
63
What is negative punishment?
behavior decreases in frequency, intensity, and/or duration because its occurrence results in the removal of a desired stimulus
64
What is the premack principle?
performing a less preferred activity to gain access to a more preferred activity
65
What is shaping?
stepwise reinforcement of relevant behaviors as they sequentially approach and build toward a target behavior
66
What is instinctive drift?
tendency for animals to resist learning behaviors relatively far afield of their natural repertoire, favoring instead the performance of instinct related behaviors
67
What is observational learning?
when behavior is learned by observing others' behavior
68
What is vicarious reinforcement?
learning from others' actions and the reinforcement
69
What is latent learning?
passive cognitive learning that is hidden because consequences are not available to support the behavior
70
What is an example of latent learning?
we know how to rob a bank because of media, but we don't do it because there is no consequence supporting the behavior
71
What was the bobo doll experiment?
first to systematically study observational learning, preschoolers observed an adult being aggressive with the doll (kicking, punching) and the kids were then invited to play with the doll and they started doing the same things the adult had
72
What is contingency management?
a treatment plan that gives immediate rewards for desired changes in behavior
73
What is avoidance learning?
when an organism learns a response in order to avoid experiencing an unpleasant stimulus
74
What is the differential reinforcement of Incompatible behavior?
reinforcing a behavior that serves as an alternative to inappropriate behavior
75
What is the differential high rates of behavior?
reinforcement is provided to increase the rate of desired behavior
76
What is differential low rates of behavior?
reinforcement is decreased in response to a behavior in order to decrease the rate of an undesired behavior
77
Why is classical conditioning passive?
learner can't choose to engage or not engage in a new behavior because the association is made through natural response
78
Why is operant conditioning active?
requires learner to actively participate and perform some type of action in order to be rewarded or punished
79
What does operant learning require?
trial-by-trial learning
80
What are 4 things observational learning requires?
attention, retention, motivation, and behavior
