Q

What did John Garcia, a learning psychologist, find that some organisms were biologically prepared to do?

25
What is Thorndike's "law of effect"?
responses that lead to satisfying consequences are more likely to be repeated
26
According to Thorndike, over time and through experience, an organism makes a direct connection between what and what without any awareness that the connection exists?
the stimulus and response
27
What is the "Skinner box" (developed by B.F. Skinner)?
a chamber with a highly controlled environment, used to study operant conditioning with laboratory animals
28
If a hungry rat is taught to press a lever in the Skinner box, what will happen? (3)
1. at first, it accidentally presses the lever as it explores its environment--and it receives a food pellet 2. it will not learn the connection the first time 3. sooner/later it presses the lever again, and in time the frequency of the pressing response increases
29
What is "reinforcement"?
the process by which a stimulus increases the probability that a preceding behavior will be repeated
30
What is a "reinforcer"?
any stimulus that increases the probability that a preceding behavior will occur again
31
What is a "primary reinforcer"?
a stimulus that satisfies some biological need and works naturally, regardless of previous experience
32
What is an example of a primary reinforcer?
food for a hungry person
33
What is a "secondary reinforcer"?
a stimulus that becomes reinforcing because of its association with a primary reinforcer
34
What is an example of a secondary reinforcer?
money for food for a hungry person
35
What is a "positive reinforcer"?
a stimulus added to the environment that brings about an increase in a preceding response
36
What is a "negative reinforcer"?
an unpleasant stimulus whose removal leads to an increase in the probability that a preceding response will be repeated
37
What is "punishment"?
a stimulus that decreases the probability that a previous behavior will occur again
38
What are the two types of punishment and how are they different?
1. positive = adds something 2. negative = removes something
39
How does positive punishment work?
weakens a response through the application of an unpleasant stimulus
40
What is an example of positive punishment?
spanking
41
How does negative punishment work?
weakens a response through the removal of something unpleasant
42
What is an example of negative punishment?
no more video games
43
What are the pros of punishment? (2)
1. appropriate for dangerous behaviors 2. temporary suppression provides an opportunity to reinforce more desirable behaviors
44
What are the cons of punishment? (4)
1. frequently ineffective 2. punished behavior may be replaced by even less desirable behavior 3. physical punishment can cause harm (fear, lowered self-esteem, etc.) 4. does not relay information about alternative, more desired behavior
45
What is a schedule of reinforcement?
the pattern of frequency and timing of reinforcement following desired behavior
46
What is a continuous reinforcement schedule?
reinforcing of behavior every time it occurs
47
What is a partial (or intermittent) reinforcement schedule?
reinforcing of a behavior some but not all of the time
48
Which reinforcement schedule maintains performance longer before extinction occurs?
partial reinforcement schedule
49
What is a fixed-ratio schedule?
reinforcement is given only after a specific number of responses are made
50
What is a variable-ratio schedule?
reinforcement occurs after an average number of responses, but the reinforcement schedule is unpredictable
51
What is the crucial factor in both the fixed-ratio schedule and the variable-ratio schedule?
the number of responses
52
What is a fixed-interval schedule?
reinforcement is provided for a response only after a fixed time period has elapsed
53
What is a variable-interval schedule?
the time between reinforcements varies around some average rather than being fixed
54
What is the crucial factor in both the fixed-interval schedule and variable-interval schedule?
the amount of time that has elapsed since the reward
55
What is stimulus control training?
behavior reinforced in the presence of a specific stimulus, but not in its absence
56
What does a discriminative stimulus do?
signals the likelihood that reinforcement will follow a response
57
What is "shaping"?
the process of teaching a complex behavior by rewarding closer and closer approximations of the desired behavior
58
What are the steps to shaping? (3)
1. start by reinforcing any behavior similar to the behavior you want the person to learn 2. later, you reinforce only responses that are closer to the behavior you ultimately want to teach 3. finally, you reinforce only the desired response
59
What are 3 examples of biological constraints that are consistent with evolutionary explanations of behavior?
1. adaptive benefits promote survival 2. associations that animals learn most readily involve stimuli that are most relevant in the specific environment in which they live 3. we may be genetically predisposed to be fearful of certain stimuli
60
What is "behavior modification"?
a technique for promoting the frequency of desirable behaviors and decreasing the incidence of unwanted ones
61
What are the steps of behavior modification?
1. identify goals and target behaviors 2. design a data-recording system and record preliminary data 3. select a behavior-change strategy 4. implement the program 5. keep careful records after the program is implemented 6. evaluate and alter the ongoing program
62
What is the "cognitive learning theory"?
an approach to the study of learning that focuses on the thought processes that underlie learning
63
What does the cognitive learning theory suggest?
it is not enough to say that people respond because there is an assumed link between a stimulus and a response, instead, people develop an expectation that they will receive a reinforcer after making a response
64
What is "latent learning"?
learning in which a new behavior is not demonstrated until some incentive is provided for displaying it (occurs without reinforcement)
65
What is a "cognitive map"?
a mental representation of spatial locations and directions
66
What is observational learning?
learning by observing the behavior of another person, or model
67
What is the genetic basis of operational learning?
mirror neurons fire when one observes another person carrying out a behavior
68
What are examples of aspects of media violence that may contribute to real-life aggressive behavior?
1. lowering inhibitions against behaving aggressively 2. predisposing us to view even nonaggressive acts by others as aggressive 3. desensitization
