I hope we get number one:)
WOWWWWWWWWWWWWW I HATE 4!! I WANT 2 BACK!
caro if you chck yur board you ill see more people put bets on 2
Do you mean most people thought 2 would be dropped?
yesss. :]
wait is two dropped?
Yes.
yesssss. :]
thank you thank you Mr. Caro. :]
SWEEEEEET That means i only have to study one topic really hard(dreams). Thank you CARO woooooot wooooot.
#4 is really hard,so now i'm freaking out.
I can't remember anything i've been studying!
20 gold stars for taking off question number two!
But I'll give you 20 more gold stars if you tell me if it's 1 or 4!
And if you buy now--you'll get a fabulous wrist watch with built in solar shower and Freudian quote of the day!
Thank you Caro! :]
I had a hard time understanding number two...
and Alex...you need a "But wait! There's more! Call within the next hour and you'll recieve a free educational video done by Zimbardo himself!"
BAH!
question 4 still plagues me.
well i guess it's great not having to study 2...
thanks FXC
Hang in there peoples!
QUESTION 2 WAS AN AMAZING QUESTION!
i'm so freaked out now
I'm just thankful you took off one of the questions.
Me too! Thanks for doing that, Caro!
I was just looking through my binder and realized I left out the first page of my dream analysis...the part where I summarize my day and the dream.
!!!!
should I just email you the summaries so you are not confused?
Alana,
Sure.
Just study hard and write down what you know. Both 1 and 4 are really good questions. 1 is extensive and 4 shows creativity. Don't get your panties in too much of a bunch.
Mr. C- I don't understand how the video you posted corresponds to the essay. Which question would that help us most on?
Haha.
Rachael!!!!
Yes, sir.
Is there a problem?
Haha. ;)
Caro,
In response to Essay #1, on the last sentence of our intro, do we come out and just say "i plan to answer this question by...", or do we list the possible ways to answer this question such as " (the question) can be answered by the Roediger and Mcdermott study?
Hey Amalan!
Never use "I".
Simply explain what you will be covering in the essay -- how you will respond to the question.
oops, brain slip!
thanks Mr Caro!
what would be the best assumption to use in question 1?
Anonymous-That the mind is an information processor. You can find that in your notes from class we took before break.
Righto! Thanks Rachael!
Anonymous-
Here's what I have on it:
Simply, behavior acquisition and change. This is the study of how people acquire, store, transform and use information. Mental processes can be studied and research can be triangulated.
That should be enough. Study on!
Caro,
The Domhoff passage has SO much information and I'm having a hard time narrowing down key points for my essay/notes on him. Can you help me? What should I focus my notes on... specifically?
Mr. Caro what are limitations to the Neural Network Model?
domhoff takes forever!!
Caro
In the Question 4 Video, you say that our notes state that dream experience changes with age--isnt that also what Domhoff says? Can we just use that?
One second....
Here is a summary of Domhoff's view of dreams:
• The Neurocognitive Theory
o Treats dreams as a kind of thinking that occurs under special conditions
o Conditions:
• Persisting activity of much of the cortex
• Great reduction of sensory stimulation, including reduced activity in the primary sensory areas of the brain
• Loss of voluntary self-control of thinking
o Thus the brain is active enough to engage in imagination, but not overridden by intentional control or sensory information
o Research:
• Griffith et al. 1958 – Japanese and U.S. students experience similar dreams
• Most common emotion in dreams is apprehension or fear
• Misfortune rather than fortune
• Dreamer is usually the victim
• 11-13 year olds have more happy dreams that people of any other age
• Frequently people dream of their concerns and very rarely of nonconcerns
o The ability to dream requires cognitive maturity
• Infants have a great deal of REM sleep but seldom can report what would be considered a dream
o No way to judge accuracy of dream content
• Example: do we dream in color?
o People who suffer eye damage after age 5 to 7 continue to have visual dreams
o People born blind have no visual imagery in their dreams; instead, they dream of sounds, touch, smells, and taste
o People who become blind because of damage to visual cortex lose visual dreaming as well as visual imagery
Bio of Memory:
The Biology of Memory
• Formation of memory involves chemical and structural changes at the level of the neuron
• Increase of the decrease in the readiness to release neurotransmitter
• Long-term Potent ional: A long-lasting increase in the strength of synaptic responsiveness, thought to be a biological mechanism of LTM
• An increase in the release of the neurotransmitter glutamate from transmitting neurons
• Chemical reactions in the glutamate receptors of receiving neurons which make these neurons more receptive to the next signal
• Dendrites grow and branch out and certain synapses increase in number
• Neural change in the brain that underlie LTM all take time to develop -- (maybe why memory is vulnerable to disruption)
• True memories trigger activity in the left-hemisphere areas involved in processing sound and speech
• False memories are stored in the frontal lobe
• Hippocampus: the gateway to memory -- declarative memory ultimately is stored in the cerebral cortex but the hippocampus is an early processing place for memories
• Procedural memories: memories for skills and habits, activity are localized in the cerebellum (ex. Thompson's rabbit)
• Different pieces of information are probably processed separately and stored at different locations distributed across wide areas of the brain with all the sites participating in the representation of the concept
• The hippocampus may bind together diverse aspects of memory at the time it is formed, so even though these aspects are stored in different sites, the memory can be retrieved as one coherent entity
• Hormones released during stress and emotional arousal enhance memory
• High levels of epinephrine (released during emotionally arousing experience) may actually make the memory too memorable
• Glucose may enhance memory either directly or by altering the effects of the neurotransmitters
Neural Networks: the mind based on the brain
• Information/knowledge is represented as connections among thousands of interacting processing units, distributed in neural networks all operating in parallel.
• Unlike the multi-store model which offers a serial model
• Connections/Associations: neurological connection
• Cognitive Units/Nodes: take on some level of activation – sets of these correspond to contents of consciousness
• Activation is enough, the mind is conscious of the activation
• Most active nodes are what the mind is attending to at that moment
• Low activation are unconscious or subconscious activations – motor actions
• LTM: The strength of connections constitute LTM of associations among nodes of information
• Learning: the strengthening of connections/associations among nodes
• Hebb’s Rule (1949): connection between two nodes is strengthened if they are simultaneously activated – this association is enhanced with attention
• Forgetting: the weakending and/or the destruction of connections across neural networks or nodes
• Can happen due to:
• Injury
• Psychoactive drugs
• Lack of activation
• Stress
• Explains the neurological workings of the Semantic Network Model
• Physical evidence: brain scans, electrode activation of the brain, studies such as:
• Lynch, rat brain tissue subjected to activation showed the formation of new neural connections
• Thompson, rabbit’s loss of brain tissue also removed the learned response
• Praag, exercise caused neural growth in the hippocampus and improved memory performance in rats
oh joy!!!!
YES!
Thanks for putting Domhoff up Mr. Caro!
Caro you are amazing! But you could have just told me to look at my notes that we took from the posted lecture notes. I'm sorry you did all that work... :/ but thank you! :)
Thank you, Mr. Caro!
how does Domhoff go agaisnt what Cartwright says?! I'm looking through things and can't find it anywhere
Well aahhrrrr (English accent) what can be satisfactory is to explain the
Domhoff offers are far more expansive theory of dreams, one that is not
rooted in any single function such as problem solving. His theory is on
that is maturational, cross-cultural, and biological. What's more, he
argues that dreams are much like thinking. Finally, he offers brain-based
evidence in that there is localization of function with respect to aspects
of dreams such as vision. If you are born blind, you lack visual dreams.
Tallyho!
Xavier
So essentially, evidence for the neural network model can be that the weakening/destruction of connections can be caused by things like stress and is shown when the person forgets a memory?
I want to make sure I'm on the right track here...
Yes! Try to find examples in your notes. One place is the article on Stressed Out Memories!
Great job Brittany!
So when you say,
"Tallyho!
Xavier"
it's the baby speaking right?
Caro!
you haven't emailed me back or replied to my comment. :[
well I will just ask you again,
What is a limitation the the Neural Network Model?
Sorry about that! Xavier took over the computer there. I don't say things like Tallyho. Xavier thinks he lives in England or something.
Yvonne! You need to read the article and notes. You just have to think about it.
One idea is that the NNM is manageable when explaining some mental processes. But when it comes to something like consciousness, it is still wanting in that it is so complex it loses its parsimonious nature.
Keep in mind, it is NOT necessary for you to evaluate the NNM. You can simply explain it. Apply it. Connect it to other things.
You are the most helpful teacher ever!! Seriously...I would be lost without the blogging brilliance.
Was stressed out memories an older assignment? I can't seem to find it
Alana,
I believe it's on page 243
okie dokie thanks...
can't think right now...
three other test scheduled tomorrow.
>.<
Xavier uses too many line breaks!
Maybe it's an English thing?
Alana stressed out memories is on page 243 of the reader.
Thank you Amalan!!
Nevermind someone already said that.
Stressed Out Memories was from just prior to the break. See page 243 in the Reader.
I'm gonna go ahead and say 243.
Remember my cognitive psychologists, you all NEED REM and Stage 4 sleep to do well on the essay tomorrow. So off to bed for all within the hour!
I really hope we get 4.
I really get the dream stuff, because its so interesting to me.
The memory stuff im not so hot in.
Hahahaha caro i just got off work, i need to study!
Oh yeah, i didnt do the dream extra cred assignment, but I did wright down a really weird dream if you care to hear about it sometime.
yeah lol i did too i was gonna tell you caro but i forgot lol and uhm i think that i hate question 4
I would love to hear it!
on the blog? ha mines so weird but it correlate to one of the brain thoerys lol
It might be best to share the dreams in person. You never know!
Hahaha im not going to share it on the blog.
Wayyyy to personal to talk about it over the blog, let alone interent, for everyone to see.
internet*
yeah same ha maybe ill tell it to you on email or something. but yeah i am gonna die on number 4. please dont pick it.
Yes i want number 4! haha i dunno what to do for 1 :p
mathias, check yo phone
i failed this too
