Cards

Term
Capsaicin
Definition
the way it stops pain is by stopping the pain receptors from firing
Term
Under normal circumstances, to experience pain we need
Definition
1) Pain receptors to fire
2) Perception of pain in the brain
Term
Soldiers vs. Patients studies
Definition
§ Soldiers wounded in combat in vietnam; 25% requested pain killers
§ 80% of civilians who had surgery requested pain killers
§ Soldiers less likely to ask for pain killers
□ Possibly because military soldiers are usually tough
□ Turns out that people started thinking that the pain was different; perception of the wound
□ Soldiers who may have seen wound as a good thing may have perceived pain less because they had a better mentality
Term
Sensory adaptation
Definition
nerves get used to certain stimulus and stop firing
Term
Endorphins
Definition
chemical produced in the brain that's really similar to opiate drugs
- They discovered the receptors in the brain before they discovered the endorphins
□ Mostly produced during highly emotional periods, and physical exertion
Term
Why do people have different reactions to pain?

Coghill et al 2003
Definition
□ Heated small area of skin to 120o -- enough so they don't feel pain
□ Also measured brain activation in the thalamus
® Why did they measure activation in the thalamus?
◊ The thalamus is a lower level brain structure and all the senses are coming through the thalamus. If we want to know how much pain info is going to the brain is the thalamus b/c that’s where info passes before going to higher level brain
□ Divided people in the high perception groups and the low perception groups
® When we look at the two do we see any differences in the amount of information that goes to the brain? NO. They both receive the same info at the lower level; info received at the receptors is the same; getting same info to the brain
□ Means that differences in pain perception has to be taking place in the higher levels of the brain
□ Conjecture: now they're trying to explain what has happened
® Past experiences coping with pain -- people with past could cope well with pain
◊ People who coped less well with pain went less well -- perceive more pain because they're going to be more anxious because of those past experiences
Term
Edwards et. Al (2009)
Definition

  • Explain what are some things that people might do
  • Catastrophizing - cognitive processes like rumination (dwell on it and think about it  a lot)
  • Pessimism - perceptions of helplessness and magnification of pain symptoms
    • The bigger mess they make of it, the more pain
  • fMRI - combo of petscan and MRI -- info about activity
    • We find that people who catastrophize have higher levels of activity in the amygdala (lower level brain center involved with emotion -- particularly fear and aggressive emotions)
  • Feelings of helplessness correlate with levels of inflammation -- in people with rheumatoid arthritis 

Term
How can we reduce pain?
Definition

- Distraction: reduce pain perception by 30%-40% - Reappraisal - Making positive statements -- this pain really isn't that bad -

 

Religious coping

Term
§ "everything psychological is simultaneously biological"
Definition
Term
□ Stevension and Repacholi (2003)
Definition
BODY ODOR!
- Children's responses to male body odor
- When smelling Butanol and Caramel, subjects did as expected
- Analyzed data by age (child or teen) and gender (male and female)
- Only female adolescents disliked the male body odor consistently
- Correlation between being able to name the smell and hedonic rating --now we find that those who can identify the smell dislike it
Term
SCN
Definition
- biological clock
- 25 hour clock
- light resets our clocks
- easier to travel from east to west
Term
Why Monday Mornings are so hard!
Definition

- You stay up late Friday night, Saturday night and your biological clock changes

- We try to go to bed on at a sensible hour on Sunday night but we cant because our SCN is saying that it's time to be awake 

Term
Circadian Rhythm
Definition

 biological cycles that occur on a daily circle 

Term
Body temperature 
Definition

  • Your body doesn’t stay the same temperature all day
  • There's a pattern
  • During a normal day when your body temp is at its peak, that’s when you're most productive
  • Causes brain to tell whether you're sleepy or awake
  • When you pull an all-nighter you get this dip in body temperature but it rises again so you feel more awake then you did a few hours ago; you get a second wind
  • Its counterintuitive because there's a large sleep debt 
  •  

Term
Sleep Deprivation
Definition

  • we become irritable 
  • memory issues, concentration difficulties, lower motivation 

Term
Strobe light Study
Definition

  • sleep deprived college students had eyes taped open and were instrucyted to push a button every time they saw a flash
  • sometimes they didn't push the button when it flashed
  • they experienced micro sleeps -- brief periods of sleep that intrude into wakefulness 

Term
Mitler et al. (1997)
Definition

Long Haul Truckers

 

 

  • They have truckers on brain monitoring equipment (EEG)
  • Also collecting data from trucks
  • AVERAGE SLEEP was 4.78 hours per day
  • 7% of the time, the truck was moving and truckers were asleep
  • Emphasizes that we're going to sleep whether we want to or not  and our brain will choose to sleep 

 

Term
REM
Definition

Rapid Eye Movement 

 


  • when we have the most vivid like dream 
  • voluntary muscles are paralyzed 
  • everyone dreams!
  • Necessary for memory retention 

 

Term
What do people dream about?
Definition
they dream about what they're thinking about during the day 
Term
nonREM Sleep 
Definition

 

  • The higher the number, the deeper the sleep
  • Theres always brain activity; its not like hibernation
  • Stage 1: probably could wake you up just by saying your name
  • Stage 4: We could do a lot of things and don't wake you up
  • When we sleep we're cut off from the outside world (sensory things)
  •  

 

Term

Is the REM sleep all that important since Stage 4 is the most important?

Definition

  • Yes; the brain keeps special track of REM sleep and it's possible to take a nap and go right to REM sleep and not go through all the stages
  • Even if you just deprive people of REM, they will still act like they did not get a good night's sleep 

Term

Peak alertness comes a different time and it is age related 

Definition

 

  • Owls - experience a peak body temperature at 8 PM
  • Larks - peak body temperature at 8 AM
    • American culture values Larks
    • "early bird gets the worm"
  • these are physiological differences 
  •

  • People can have some awareness of dreaming and have some control 

Term

What do dreams mean?

 

(2 views)

Definition

 

  • Activation synthesis view
    • dreams have no meaning; it's all randomness; you get random signals from lower brain centers
    • Dreams are the brain's attempt to make sense of activity

 

  • Freud's view 
    • believes dreams are symbolic
    • usually has to do with sex

 

Term

Dreaming:

 

Domhoff's view 

Definition

  • Also interested in physiology of dreaming 
  • What's going on that makes dreaming dreamlike?
  • Speculates that content may be meaningful
  • Outlined ways to study content in a scientific way
  • Found things like: children are more likely than adults to dream about animals

Term

Alcohol:

 

Ridderinkholf et al (2002)

 

Definition
  • How well do we notice our mistakes when we're under the influence of alcohol?
  • Social Drinkers  -- ruling out people that have alcohol problems
  • Simple video game - practiced it until they were perfect at it 
  • Randomly assigned to 3 conditions
    • Placebo --sparkling grape juice
    • Alcohol with BAC .04 moderate
    • BAC .10 -- high alcohol consumption group
  • Performed computer game again under these conditions
  • Participants in both alcohol groups failed to notice mistakes
  • They were looking for activity in the anterior cingulate cortex (area of the brain that is active when we know we've made a mistake) -- "opps response"
  • Even when you're perfectly legal its hared to know if you made a mistake
  •  
Term
Alcohol Myopia
Definition

Focus on present

 

reduced ability to see negative consequences

Term
Joson et al (2000)
Definition
  • no alcohol - ice water
  • Placebo - drank tonic water but there was vodka on the glass rim so that people would get a taste of alcohol; 60% thought they consumed at least one drink
  • Low alcohol - BAC brought to .025% -- 94% thought they had at least 1 drink
  • Moderate alcohol - BAC .065% -- 100% thought they consumed at least 1 drink
  • Asked questions like should the man try to have sex with the woman even if it means using force     

Results: 

  • In non receptive condition -- alcohol made no difference 
  • Moderate and low alcohol conditions now significant difference compared to no alcohol 
  • To be fair, we're asking people if they agree with rape

Reed et al (1996)
Definition

  • People randomly assigned to be hypnotized or pretend that they're hypnotized
  • They were asked to listen to a pair of tones and tell which one is louder
  • They were told that in between the tones that they were going to dip deeper into hypnosis and that they may not even hear the second tone
    • If they're following the tones, they should  say that the first tone should be louder
    • Those pretending to be hypnotized followed the instructions and reported first tone as louder
    • The really hypnotized reported accurately
    • People who are hypnotized and aren't respond differently

Term
Positive reinforcement 
Definition

providing a desired stimulus following the target behavior

 

rate of target behavior increases 

Term
Negative Reinforcement 
Definition

increasing behaviors by stopping or reducing negative stimuli, such as a shock.  A negative reinforcer is any stimulus that when removed after a response, strengthens the response 

 

ex) aspirin relieves headache therefore these provide negative reinforcement and increase the likelihood that you will repeat these behaviors

Term
shaping

positive reinforcement 

 

teaching a behavior by positively reinforcing successive approximations of that behavior

 

ex) dog training and child rearing 

 

 

 

Term
Wolf et al (1964)
Definition

classical conditioning

 

    • Boy with autism needed eye surgery and needed glasses for his eyes to heal properly

    • When boy wears glasses, they use clicker and boy is happy 

Term

  • Reinforcement must be contingent upon performance

Definition
Term
Positive punishment 
Definition
presenting an aversive stimulus following the target behavior which then reduces the rate of the target behavior
Term
negative punishment 
Definition

removing a desired stimulus following the target behavior; makes the target behavior less frequent 

 

ex) Time out 

Term
Lang and Melamed (1969)
Definition

  • Little boy who is throwing up his food and can't keep anything down and has had surgery to keep it down
  • Things tape to his face send electric shock when he starts gagging (positive punishment)

Term
intermittent reinforcement 
Definition

 reinforcing a response only part of the time; results in slower acquisition of a response but much greater resistance to extinction than does continuous reinforcement

 

ex) NYC traffic lights 

Term

Tolman and Hozrik (1930)

Definition

one has to be reinforced to learn 

 

Rats in a maze ran 10 times without any reinforcement 

 

the 11th time, there was reinforcement in the end

12th time, rats ran the maze quickly 

Term
Observational learning 
Definition
learning by observing others 
Term
Albert Bandura
Definition

observational learning theory

 


said we can learn from watching others 

Term
Molitor and Hirsh (1994) 
Definition

observationaly learning theory 


experiment to see if we can change people's short term tolerance for aggression in the lab

 

  • Randomly assigned kids to 2 groups 
  • one -- trace and field events // two -- assigned to moderate violence conditions
  • kids who watched violent scene took twice as longer to get the experimenters -- represents tolerance for aggression 



Term
Vicarious reinforcement
Definition

observational learning 

 

ability to imagine the effects of a reinforcer -- makes the target behavior more likely to happen 

 

ex) man buying wife flowers -- associates flowers with hugs, kisses 

Term
vicarious punishment 
Definition

observational learning 

 

ability to imagine effects of a punisher - makes target behavior less likely

Term
Ebbinghaus
Definition

memory in the purest form 

 

 

  • used nonsense syllables, consonant vowel consonant (HEB)
  • Ebbinghouse found that it was hard for him to recall the words, but when he went to go back and study it, he found it easier to pick up again 

 

Term
Serial Learning 
Definition
requires free recall in order 
Term
saving score 
Definition

difference between the time requres to learn and relearn material 

 

shows that Ebbinghaus had a memory for it even though he couldn't access it; there was something still there in his brain 

Term
recognition 
Definition
can you tell us if you've seen it before??
Term
Curve of Forgetting 
Definition

course of forgetting is initially rapid and levels off with time 

Term

model of memory

 

 

Definition

Atkinson-Shiffrin

Definition

15 seconds unless we rehearse it 

 

7 plus or minus 2

Term
Chunks
Definition

memory

 

meaningful cohesive units of information 

 

ex) acronyms

Term
encoding
Definition

maintenance vs elaborative

 

  • maintenance -- reading over book, reading over notes; repetition 
  • elaborative -- more effortful; relating it to otehr things 

Term
Spacing effect
Definition
spreading out the studying improves recall
Term
Bjork et al (2008)
Definition

tried doing a study where cramming works best 

 

they had students study a concept learning, learning to identify work by little known artists 

 

spacing beat cramming!!

Term
long term memory is organized like.. 
Definition

a semantic network 

 

  • semantic network -- connections of related ideas 
    • capacity is unlimited 
    • the more ideas you know, the more ideas you have to connect to 
  • ex) kids being red to before they go to school have more developed semantic network they can connect new information to 

Term
priming 
Definition
activating elements of a semantic network 
Term
Anderson (study)
Definition

priming :: observation learning theory approach

 

  • people randomly assigned to play video games 
  • one -- violent condition \\ two -- non violent (tetris)
  • asked to fill in word M U _ _ E R
  • one -- MURDER \\ two -- MUDDER
  • those in nonviolent condition were less likely to create aggressive words
  • video games activating aggressive side of our semantic network 

Term
context effects (of recall)
Definition
ex) you're prone to recall more when you are in the same context at test time as when you learn it 
Term
state dependent memory
Definition

you're goign to recall information best when we are in the same mental state (mood) at encoding and retrieval 

 

ex) if you can't stand the class, you'll do better coming in and taking the test angry 

Term
mood congruent memory
Definition

we tend to store and recall information that is consistent with our current mood 

 

ex) those suffering from depression will store many memories that are negative -- why people who are depressed are continually depressed 

Term
Loftus (1974)
Definition

reliability of memories

 

  • showed popel movie of a car accident and asked questions 
  • HOw fast were the cars going when they ______ each other?
    • smashed, collided, bumped, hit, contacted
  • one word made a significant estimate about speed 
  • shows that it's easy to manipulate memory 

2 weeks later followup:

  • Broken glass? -- one word significance still had an effect on the person's memory 2 weeks later 

Term
Well et al (2003)
Definition

interested in people's memory for a crime scene 

  • had people watch a video of a crime and determine the perpetrator who was not present 
  • dependent variable -- confidence in selection 
  • Disconfirming feedback had no effect -- didnt matter if it came right away or late, they didn't change their confidence 
  • confirming feedback increased people confidence
  • timing of feedback had no effect 
when we give people confirming feedback we can make them more confident in their answer even 48 hours later

Term

Term
implicit
Definition

nondeclarative memory

 

unconscious capacity

 

skills taht you could not explicitly explain

sometimes the problem is that things never get encoded in the first place 
Term
interference
