WHAT IS LEARNING?
Define learning (Objective 1)
1. The relatively permanent change in behavior or behavioral ability of an individual that occurs as a result of experience is called learning .
2. The fact that the individual's behavior is modified and continues to remain different is why we say learning is relatively permanent .
3. Learning results from behavioral experience in the environment. In order to learn, we need to perceive events in our environment, and to associate them with our behavior.
CLASSICAL CONDITIONING
Identify the Types of Stimuli and Responses Involved in Classical Conditioning (Objective 2)
4. Ivan Pavlov taught dogs to salivate at the sound of a bell which was initially followed by food. Pavlov called this form of learning classical conditioning.
5. In classical conditioning, any stimulus that provokes an automatic or reflexive reaction in an individual is an unconditioned stimulus, or US.
6. The particular response elicited by the unconditioned stimulus is the unconditioned response, or UR.
7. If the US is repeatedly presented following a neutral stimulus, the neutral stimulus alone will become sufficient to elicit the response and is now called the conditioned stimulus, or CS.
8. The learned response to the conditioned stimulus is the conditioned response, or CR.
Outline the Basic Principles of Classical Conditioning (Learning Objective 3)
9. In Pavlov's experiment, the bell is the CS, the meat is the US, the response to the meat is the UR, and the response to the bell after conditioning is the CR .
10. Watson and Rayner (1920) taught Little Albert to fear a white rat by pairing the rat with a loud, unpleasant noise. The loud noise in this study was the US , or unconditional stimulus.
11. It has been found that efficient acquisition of classical conditioning takes place when the CS precedes the US by a very brief time period, called the interstimulus interval.
12. The presentation of the CS precedes the onset of the US and the termination of the CS is delayed until the US is presented in delayed conditioning. This is the most effective type of conditioning procedure.
13. The CS is a discrete event that is presented and terminated before the US is presented in trace conditioning. This is very effective if the interstimulus interval is very brief.
14. The CS and the US are presented at exactly the same time in simultaneous conditioning.
15. The US is presented and terminated before the presentation of the CS in backwards conditioning. This is not effective.
16. When the conditioned stimulus is presented by itself, after a while the conditioned response declines until it is nonexistent, in a process called extinction .
17. If the subject is given a rest during extinction, the CR will occur again briefly due to spontaneous recovery.
18. Once a conditioned stimulus becomes effective, other similar stimuli also can elicit the conditioned response, a process called stimulus generalization .
19. The subject learns to respond only to a particular stimulus that is paired with the US in stimulus discrimination .
20. If a neutral stimulus is presented consistently before a CS, the neutral stimulus alone might come to elicit the CR, in a process called higher order conditioning.
Describe How Taste Aversions Might Be Acquired through Classical Conditioning (Learning Objective 4)
21. When an individual experiences stomach distress after having eaten something, conditioned taste aversion , or CTA, to the thing eaten is said to have occurred.
22. John Garcia gave rats sweetened water and then produced gastrointestinal distress by exposing them to radiation. A few days later, the rats refused to drink sweetened water. The X ray (US) that caused the stomach distress (UR) had been associated with the sweetened water (CS), so the water became associated with illness ( CR ).
23. Conditioned taste aversion, or bait shyness, is a unique form of classical conditioning because the interstimulus interval can be hours rather than seconds, and because CTA can occur in only one trial.
24. In a study of coyote predation control, the researchers took sheep meat (CS) and sprinkled it with a chemical (US) that would produce a stomachache (UR) when the coyotes ate the treated meat. After eating the treated meat, the coyotes avoided the live sheep.
OPERANT CONDITIONING
State Thorndike's Law of Effect (Learning Objective 5)
25. The cats in Thorndike's puzzle box used trial and error learning when they escaped. Thorndike called this form of learning instrumental conditioning.
26. Thorndike found that any response that produces satisfaction in a given situation becomes associated with that situation. When that situation occurs again, the response is more likely to be repeated. This is called Thorndike's law of effect .
Define Shaping and Describe an Example (Learning Objective 6)
27. The gradual process of reinforcing successive behavior approximations toward some goal is called shaping .
28. In each step of shaping, reinforcement is withheld until the subject emits a response just a little closer to the end goal desired.
Outline the Basic Principles of Operant Conditioning (Learning Objective 7)
29. Shaping is an effective method to acquire or learn a behavior through operant conditioning. But we also find through trial and error learning, what causes reinforcement to occur.
30. A chamber developed by B. F. Skinner which has a lever that when pressed, results in reinforcement for a subject, is called a Skinner box, and is used to study operant conditioning.
31. In operant conditioning, the withholding of reinforcement with the subsequent effect of the behavior decreasing in frequency is defined as extinction .
32. Just as in classical conditioning, if the subject is given a rest during extinction, he or she will respond with the conditioned response again briefly due to spontaneous recovery.
33. Responding to stimuli that are similar to ones that have led to reinforcement in the past is stimulus generalization .
34. When the subject is reinforced for responding to particular stimuli only, the process is called stimulusdiscrimination .
Define Reinforcement and Describe the Major Schedules of Reinforcement (Learning Objective 8)
35. Any event that increases the probability that the behavior that precedes it will be repeated is defined asreinforcement .
36. The principle that states that of any two responses, the one that is more likely to occur can be used to reinforce the response that is less likely to occur is called the Premack Principle.
37. In continuous reinforcement, or the procedure of reinforcing every correct response, the schedule leads to rapid acquisition and rapid extinction of a behavior.
38. In partial reinforcement schedules, the subject is reinforced after some responses but not after others. These schedules are based on the time interval between reinforced responses and the ratio of unreinforced to reinforced responses.
39. The fact that partial reinforcement produces a response that takes longer to extinguish than continuous reinforcement is called the partial reinforcement extinction (PRE).
40. The subject must make a certain number of responses before reinforcement is given in the fixed ratio schedule of reinforcement. An example is piecework.
41. In the variable ratio schedule of reinforcement, the number of responses required by a subject varies trial by trial, but is averaged overall. An example is gambling on a slot machine.
42. The subject receives reinforcement for the first response after a time interval in the fixed interval schedule of reinforcement. An example is a salary.
43. In the variable interval schedule of reinforcement, the subject is reinforced for the first response after a particular time interval, with the interval being different for each trial, but averaged overall. An example is an instructor giving unannounced quizzes.
Contrast and Give Examples of the Different Types of Reinforcement (Primary and Secondary Reinforcement, and Positive and Negative Reinforcement) (Learning Objective 9)
44. Reinforcement that is effective without having been associated with other reinforcers is primary reinforcement. An example might be food.
45.
Reinforcement that is effective only after it has been associated with a primary reinforcer is secondary reinforcement. An example might be money.
46. Reinforcement, which when presented strengthens the response it follows, is called positive reinforcement. An example might be candy or money.
47. Reinforcement, which when removed strengthens the response it follows, is called negative reinforcement. An example might be removing a stone from your shoe.
48. Positive reinforcement might be thought of as presenting something pleasant, whereas negative reinforcement is removing something unpleasant. The key point is that reinforcement increases behavior.
Describe the Procedures of Aversive Conditioning: Escape Conditioning and Avoidance Conditioning (Learning Objective 10)
49. A subject is presented with an aversive stimulus from which he or she must learn to escape in escape conditioning.
50. A subject learns to avoid an unpleasant stimulus by responding appropriately before it begins in avoidance conditioning.
Define Punishment and List the Variables that Contribute to its Effectiveness (Learning Objective 11)
51. punishment decreases the probability of the behavior preceding it being repeated.
52. Punishment can consist of presenting something unpleasant (positive punishment) or removing something pleasant (negative punishment). The key point is that punishment decreases behavior.
53. Reinforcement and punishment are defined by their consequences. If the behavior increases, it is reinforcement, and if the behavior decreases, it is punishment .
54. The application of operant conditioning techniques to change behavior, as used in child rearing, school systems, mental institutions, and animal training, is called behavior modification .
55. When individuals are given tokens when they perform a desired behavior, they are in a behavior modification program called a token economy .
56. The technique of presenting educational material in a series of small steps with student feedback and reinforcement is called programmed learning.
57. Classical and operant conditioning share many of the same basic principles, including acquisition, extinction, spontaneous recovery, and stimulus generalization.
58. One difference between operant and classical conditioning is that much of operant conditioning is based on voluntary behavior, whereas classical conditioning often involves involuntary reflexive behavior.
COGNITIVE LEARNING
Describe the Major Forms of Cognitive Learning (Latent Learning and Observational Learning) (Learning Objective 12)
59. Learning in which the person utilizes cognitive structures in memory to make decisions about behavior is called cognitive learning.
60. Learning that occurs when an individual acquires knowledge of something but does not show it until motivated to do so is called latent learning.
61. Tolman found that rats who were run through a maze for 10 days without receiving reinforcement and who finally received reinforcement on day 11, immediately did as well as rats who were always reinforced.
62. Tolman suggested that rats who were run in a maze developed a cognitive map or mental representation of the maze.
63. According to social learning theory, people learn by observing and imitating how other people behave.
64. Bandura stated that for observational learning to be effective, we must pay attention to the model, remember our observations when we are motivated to display the behavior, and receive reinforcement when we actually engage in the behavior.
BIOLOGICAL CONSTRAINTS ON LEARNING
Outline the biological constraints on learning (instinctive drift, imprinting, and the continuum of preparedness in learning). (Learning Objective 13)
65. There are biological constraints on what can be efficiently learned. The process in which learned behavior moves toward more innate patterns is called instinctive drift.
66. The tendency in just hatched birds to follow a moving object is called imprinting .
67. Seligman proposed that animals are prepared to associate certain stimuli and responses, but unprepared to learn other associations. This is called the continuum of preparedness .
68. In the continuum of preparedness, conditioned taste aversion, in which the association is formed after one trial, is an example of prepared learning.
69. In the continuum of preparedness, a person learning to spell a word after a number of trials, is an example of unprepared learning.
70. In the continuum of preparedness, trying unsuccessfully to teach a dog to yawn for food in numerous trials, is an example of contraprepared learning.
