Q

What is conditioned tolerance?

A

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

Q

Thorndike and The Law of Effect

A

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

Q

What is shaping?

A

reinforcing behaviors that are increasingly similar to the desired behavior

31
Q

What is Operant Conditioning?

A

association between a behavior and an outcome

-behavior is influenced by rewards/punishments

32
Q

What is positive reinforcement?

A

PRESENTING a stimulus ater a behavior to INCREASE the probability that the behavior will be repeated
“adding something”

33
Q

What is negative reinforcement?

A

REMOVING a stimulus after a behavior to INCREASE the likelihood of the behavior occurring again (ex. buckle seatbelt to turn off alarm)

34
Q

Extra Credit Question: what car does Professor Segert drive?

A

Honda Accord

35
Q

What is positive punishment?

A

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
Q

What is negative punishment?

A

REMOVING a pleasant stimulus after a behavior to DECREASE the probability of the behavior reoccurring (ex. sent to room and no TV)

37
Q

What is observational learning?

A

the acquisition or modification of a behavior after exposure to at least one performance of the behavior
–> learning by imitating others

38
Q

Bandura and BoBo Doll

A

two groups of preschoolers shown video of adults interacting with BoBo doll (either aggressively or quietly)
-children imitated the adults

39
Q

What is modeling?

A

imitation of behavior

40
Q

What is vicarious learning?

A

learning the consequences of an action by watching others being rewarded or punished for performing the action

41
Q

Vicarious reinforcement vs. vicarious punishment

A

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
Q

What is the relationship between media and violence?

A

desensitization to violence after exposure to violent video games

43
Q

What is memory?

A

persistence of learning, who were are –> contributes to sense of self

44
Q

Henry Molaison (HM)

A
  • 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
Q

Summary of HM

A

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
Q

Clive Wearing

A
  • got encephalitis–> lost old memories/couldn’t form new

- could only remember wife as if he hadn’t seen her in years

47
Q

Summary of Clive Wearing

A

-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
Q

Highly Superior Autobiographical Memory

A

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
Q

Extra Credit: What game show was Professor Segert on?

A

Jeopardy

50
Q

What is explicit memory?

A

conscious memories

51
Q

What is declarative memory?

A

information retrieved from explicit memory, knowledge that can be declared

52
Q

What is implicit memory?

A

unconscious memory

-w/o deliberate effort or awareness of remembering anything

53
Q

What are the types of explicit memory?

A
  1. episodic

2. semantic

54
Q

What is episodic memory?

A

memory for one’s personal past experiences (ex. HM remembering hiking the Mohawk Trail)

55
Q

What is semantic memory?

A

knowledge of facts about the world, independent of personal experience (ex. knowing London is the capital of England)

56
Q

What are the types of implicit memories?

A
  1. procedural
  2. priming
  3. conditioning
57
Q

What is procedural memory?

A

involves motor skills, habits, and other behaviors employed to achieve goals (ex. coordinating muscles to ride a bike)

58
Q

What is priming?

A

enhanced identification of objects/words as a result of recent exposure to the stimulus

59
Q

What is conditioning?

A

automatic response to a neutral cue paired with a strong stimulus

60
Q

What is prospective memory?

A

involves remembering to do something at a future time, can be triggered by a cue, takes up cognitive space

61
Q

What are the anatomical structures involved with memory?

A
  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
Q

Drug addiction cues

A

cues lead to activation in the prefrontal cortex and various regions of the limbic system (brain areas involved with reward)

63
Q

What is a reinforcer?

A

a stimulus that follows a response and increases the likelihood that the response will be repeated

64
Q

What are the schedules of reinforcement?

A
  1. fixed ratio schedule
  2. variable ratio
  3. fixed interval
  4. variable interval
65
Q

What is a fixed ratio schedule?

A

reinforcement provided after a specific number of occurrences (ex. get a free coffee after buying 10)

66
Q

What is a variable ratio?

A

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

the use of operant conditioning techniques to eliminate unwanted behaviors and replace them with desirable ones

71
Q

What is latent learning?

A

learning that takes place in the absence of reinforcement (ex. learn that turning wheel = car turning)

72
Q

Mineka monkey studies

A

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
