Q

What is counterconditioning?

A

reversing a learned response

  • take CS, pair with new US, that produces opposite response (ex. exchange rat/loud noise with rat/ice cream)
  • US must outweigh CS (ex. love ice cream but only mildly afraid of rats)

Q

What is systematic desensitization?

A

type of counterconditioning

  1. replaces anxiety with relaxation
  2. starts with exposure to least scary version of feared thing
  3. instruct person to relax while exposed to stimulus
  4. gradually move to progressively stronger versions until full/normal exposure is reached

Q

What are conditioned cravings?

A
  1. environmental drug cues (CS): rooms, friends, drug apparatus
  2. cravings (CR)
  3. sight of drug cues: activation of reward centers in brain, in expectation that the drug high will follow

Treatment for drug addiction
1. exposure therapy: extinction of CR (cravings) to environmental cues (ex. friends without doing drugs) 2. counterconditioning: giving drug that when people drink alcohol it makes them feel sick
26
What is conditioned tolerance?
environmental stimuli associated with drug produce compensatory CR --> ex. heroin (US) leads to decreased heart rate needle/room (CS) leads to increased heart rate --> body is compensating to keep HR up and if person were to go into a different room they could die because HR drop could kill them
27
What are the implications of drug overdose?
?
28
Thorndike and The Law of Effect
Thorndike studied whether nonhuman animals showed signs of intelligence -"puzzlebox" with trapdoor that only opened to a certain action -used food-deprived cats and put food outside of box Law of Effect: any behavior that leads to a "satisfying state of affairs" is likely to occur again, any behavior that leads to an "annoying state of affairs" is less likely to happen again
29
Skinner and the Shaping of Behavior
Skinner Box: put rats in chamber and see how long it took them to push a lever with different rewards/punishments
30
What is shaping?
reinforcing behaviors that are increasingly similar to the desired behavior
31
What is Operant Conditioning?
association between a behavior and an outcome | -behavior is influenced by rewards/punishments
32
What is positive reinforcement?
PRESENTING a stimulus ater a behavior to INCREASE the probability that the behavior will be repeated "adding something"
33
What is negative reinforcement?
REMOVING a stimulus after a behavior to INCREASE the likelihood of the behavior occurring again (ex. buckle seatbelt to turn off alarm)
34
Extra Credit Question: what car does Professor Segert drive?
Honda Accord
35
What is positive punishment?
PRESENTING an unpleasant stimulus after a behavior to DECREASE the probability of the behavior reoccurring (ex. going off topic --> duct tape pulled off arm)
36
What is negative punishment?
REMOVING a pleasant stimulus after a behavior to DECREASE the probability of the behavior reoccurring (ex. sent to room and no TV)
37
What is observational learning?
the acquisition or modification of a behavior after exposure to at least one performance of the behavior --> learning by imitating others
38
Bandura and BoBo Doll
two groups of preschoolers shown video of adults interacting with BoBo doll (either aggressively or quietly) -children imitated the adults
39
What is modeling?
imitation of behavior
40
What is vicarious learning?
learning the consequences of an action by watching others being rewarded or punished for performing the action
41
Vicarious reinforcement vs. vicarious punishment
reinforcement: likelihood that observers behavior is increased if model's behavior is reinforced punishment: likelihood that observers behavior is decreased if model's behavior is punished - -> reinforcement is MORE effective, not equal
42
What is the relationship between media and violence?
desensitization to violence after exposure to violent video games
43
What is memory?
persistence of learning, who were are --> contributes to sense of self
44
Henry Molaison (HM)
- could not form memories - 1935: hit by car on bike --> epileptic seizures --> remove hippocampus to stop seizures - result: could only remember things 6-9 months before surgery, couldn't remember doc/nurses (no new memories) - could still do familiar tasks - short term memory intact, could carry on convo - could learn new motor tasks
45
Summary of HM
Hippocampus: crucial for long-term memory --> anterograde amnesia: unable to form new memories Medial Temporal Lobes: responsible for coordinating and strengthening the connections among neurons when something is learned, particularly important for the formation of new memories --> why HM had old memories but couldn't form new ones
46
Clive Wearing
- got encephalitis--> lost old memories/couldn't form new | - could only remember wife as if he hadn't seen her in years
47
Summary of Clive Wearing
-damage to frontal lobe and hippocampus/frontal lobe retrograde amnesia: lost memories from past anterograde amnesia: unable to form new memories --> could still play piano, sight-read music
48
Highly Superior Autobiographical Memory
able to remember everything about your life -no difference in standard lab tests, but exceptionally accurate memory for autobiographical memory brain diff: larger temporal lobe
49
Extra Credit: What game show was Professor Segert on?
Jeopardy
50
What is explicit memory?
conscious memories
51
What is declarative memory?
information retrieved from explicit memory, knowledge that can be declared
52
What is implicit memory?
unconscious memory | -w/o deliberate effort or awareness of remembering anything
53
What are the types of explicit memory?
1. episodic | 2. semantic
54
What is episodic memory?
memory for one's personal past experiences (ex. HM remembering hiking the Mohawk Trail)
55
What is semantic memory?
knowledge of facts about the world, independent of personal experience (ex. knowing London is the capital of England)
56
What are the types of implicit memories?
1. procedural 2. priming 3. conditioning
57
What is procedural memory?
involves motor skills, habits, and other behaviors employed to achieve goals (ex. coordinating muscles to ride a bike)
58
What is priming?
enhanced identification of objects/words as a result of recent exposure to the stimulus
59
What is conditioning?
automatic response to a neutral cue paired with a strong stimulus
60
What is prospective memory?
involves remembering to do something at a future time, can be triggered by a cue, takes up cognitive space
61
What are the anatomical structures involved with memory?
1. Hippocampus: necessary for creation of new episodic memories, spatial memory 2. Frontal Lobe: necessary for "working memory," holds info to be used for solving problems, understanding conversations, and following plans 3. Amygdala: necessary for implicit emotional memories 4. Cerebellum: necessary for procedural memories (classical conditioning)
62
Drug addiction cues
cues lead to activation in the prefrontal cortex and various regions of the limbic system (brain areas involved with reward)
63
What is a reinforcer?
a stimulus that follows a response and increases the likelihood that the response will be repeated
64
What are the schedules of reinforcement?
1. fixed ratio schedule 2. variable ratio 3. fixed interval 4. variable interval
65
What is a fixed ratio schedule?
reinforcement provided after a specific number of occurrences (ex. get a free coffee after buying 10)
66
What is a variable ratio?
reinforcement provided after a variable number of occurrences (ex. slot machine - keep playing because you don't know when you'll win) *greater response than fixed ratio
67
What is a fixed interval?
reinforcement after specific amount of time (ex. paid every 2 weeks)
68
What is a variable interval?
reinforcement provided at different times (ex. salesperson gets commission once buyer purchases product)
69
What is the partial-reinforcement extinction effect?
the greater persistence of behavior under partial reinforcement than under continuous reinforcement
70
What is behavior modification?
the use of operant conditioning techniques to eliminate unwanted behaviors and replace them with desirable ones
71
What is latent learning?
learning that takes place in the absence of reinforcement (ex. learn that turning wheel = car turning)
72
Mineka monkey studies
monkeys in labs didn't fear snakes, monkeys in wild did | -lab monkeys were shown wild monkey's response --> they developed a fear of snakes
73
Social Fear of Learning
developing fear based upon society | ex. afraid of specific neighborhood because there was a news video of a person being assaulted there
