there goes 6 or 7 marks making my A+ impossible =='

Q13 C or D is incorrect. Its just D
If you have a pacemaker you can't undergo an MRI Scan due to the magnetic shit
-
according to you i got about 3 or 4 wrong is taht good or bad???
-
but u also cant undergo a fmri if u have a pacemaker can u ?
-
Q13 C or D is incorrect. Its just D
If you have a pacemaker you can't undergo an MRI Scan due to the magnetic shit
My guess it that they'll have to accept both due to the wording of the question. But I don't know.
Refer to discussion regarding this here: http://vcenotes.com/forum/index.php/topic,14345.msg155620.html#msg155620
-
Whoops I meant B or D, not C or D
-
crap. i missed the bit about function.
-
but u also cant undergo a fmri if u have a pacemaker can u ?
Yeah. That's why there were no correct answers. So my guess is that they'll have to accept both PET and fMRI, because they specified that it had to be the 'function' of the brain.
but u also cant undergo a fmri if u have a pacemaker can u ?
yeah i think your right. I said 'A' because you dont always need an injection for CT and if you do its only die.
Yeah, but the question specified he needs information about 'brain function'. CT only shows anatomy.
-
there goes 6 or 7 marks making my A+ impossible =='
Don't worry yet! These are only suggested according to me. There may be a couple of correct responses to some questions (usually happens every year). Also double check over the exam and let me know if you disagree with any of the suggested answers.
-
For question 39 could it possibly be D because there is some very small muscle movement during REM sleep?
-
does sleep talking occur in both rem and nrem? i always thought it only happend in stage 3/4 nrem.
-
question 43 is C not D.
Sleep talking can only occur during stages 3 and 4 of NREM and never occurs in REM sleep
-
For question 39 could it possibly be D because there is some very small muscle movement during REM sleep?
yeah, what about the movement of muscles around the eyes that an EOG measures?
-
Question 13 should be A.
CT uses X-rays.
It can't be PET because of injections, it can't be MRI due to MAGNETIC Resonance Imaging, and it can't be fMRI for the same reason, as well as the fact that injections are used in fMRI too.
Question 17 should be D. The patient MUST be conscious for it to be effective, so therefore mild electrical corrent is MOST correct.
Apart from that it is all good.
The only mark I dropped was on the camouflage question, I misread it and chose A instead of C.
Sigh.
-
i lost 7 marks i think. 1 or two on massivly stupid things now that i read the question.
Hopefully i picked my game up in short answer but tbh i dont think i did :S
-
question 43 is C not D.
Sleep talking can only occur during stages 3 and 4 of NREM and never occurs in REM sleep
Sleep Talking does occer in REM

Incorrect to be honest.
CT does not show function and the question asks for function not structure. fMRI does not use magnets, it just detects the oxyegen level in the blood flowing around the brain. So as stated before the correct asnwer is D
for question 17. you need to read it.
its talking about ESB
D states: electroencephalograph (EEG not ESB) gives a electic current and therefore that asnwer is incorrect do u not agree>
-
question 43 is C not D.

No, sleep talking occurs during NREM and REM sleep.

It can't be PET because of injections, it can't be MRI due to MAGNETIC Resonance Imaging, and it can't be fMRI for the same reason, as well as the fact that injections are used in fMRI too.

Unfortunately it's not D. It says "electroencephalograph" in front of it.
Question 17
Which o f the following is the most correct statement about electrical stimulation o f the surface o f the brain?
A. It is a non-invasive method.
B. The patient may be conscious.
C. The electrical current cannot be precisely delivered.
D. The electroencephalograph delivers a mild electrical current.
-
question 17 was B. (not D)
Question asks:
which of the following is the most correct satement about the electrical stimulation of the surface of the brain?
A) it is non invasive
B) The patient may be conscious
C) The electrical current cannot be precisely delivered
D) The electroencephalograph delivers a mild electrical current. -- *NOTE electroencephalogram
-
Also, patients don't always need to be conscious during ESB
for e.g. when the primary motor cortex is stimulated, an individual's leg may twitch. They do not need to be awake for this to be observed.
Although yes, generally they are conscious.
-
25 is C as that is the best possible answer.
13 is A- can't be c or d due to pacemaker. cant be b due to injection of radioactive glucose solution. so A is the best possible answer.
otherwise all the other answers are good!
-
JessieO could question 39 be D?
Because there can be some very slight muscle movement during REM sleep
-
JessieO could question 39 be D?
Because there can be some very slight muscle movement during REM sleep
That is correct. It cannot be A because NEVER any movement is incorrcect.
The EMG shows LITTLE activity not completely no activity. You are correct!
-
Ohh I'm so mad i completely misread question 39 hahaha.
Looks like I did ok.. Mainly dropped marks in research methods!
Grrrrrrrr
-
i agree that 39 could be D
muscles undergo partial paralysis during REM sleep, therefore less muscular movemennt
-
JessieO could question 39 be D?
Because there can be some very slight muscle movement during REM sleep
Yeah, you're right.
-
25 is C as that is the best possible answer.
13 is A- can't be c or d due to pacemaker. cant be b due to injection of radioactive glucose solution. so A is the best possible answer.
otherwise all the other answers are good!
But a CT scan doesn't show function so how can it be a?
And with q 25, it is about size constancy so the viewers perception would not change. so it would be a.
-
Question 17 should be D. The patient MUST be conscious for it to be effective, so therefore mild electrical corrent is MOST correct.
No alternative D stated the EEG delivers a mild electrical current.
Thats incorrect... it did not say ESB!!!
so the answer has to be B!
[/quote]
-
LOL at some of you do you read the above posts?
@ jsher. 25 is not C. The perception does not change due to the perceptual constancy of shape and/or size. It is A
Also as stated before, CT DOES NOT give details about Function which the question is asking so it is fMRI which does not use magnets like MRI.
-
Question 42
sleep apnea is defined as
C) temporary cessation of breathing for 2 to 20 seconds
D) temporary cessation of breathing for 20 seconds to 2 minutes
What did everyone else put???
-
its D
-
25 is C as that is the best possible answer.
13 is A- can't be c or d due to pacemaker. cant be b due to injection of radioactive glucose solution. so A is the best possible answer.
otherwise all the other answers are good!

[/quote
An elderly women with a pacemaker, needs to have a brain scan to investigate a possible brain abnormality- that is what a CT can show. It can't be c or d due to pacemaker and cant be b as PET involves injection of radioactive glucose solution
-

Question 41
Mel is sufering from hypersomnia
He is likely to;
A) fall asleep immediately upon going to bed
D) experience sudden NREM sleep episodes during wakeful periods of the day.
I put (D) ??????

Although that is true, the question says: "wants to investigate the <b>function</b> of Zoe's brain" CT scans do not show function, only structure.
I suppose we won't know the correct answer until the results come!
-
No, all of them are incorrect in some way.
fMRI uses magnets. That's what the M stands for. An fMRI uses the same base technology as an MRI. An fMRI takes a lot of MRI, but it still uses the same magnetic principle.
This is on a fMRI safety warning.
"Safety is a very important issue in all experiments involving MRI. Potential subjects must ensure that they are able to enter the MRI environment. Due to the nature of the MRI scanner, there is an extremely strong magnetic field surrounding the MRI scanner (at least 1.5 teslas, possibly stronger). Potential subjects must be thoroughly examined for any ferromagnetic objects (e.g. watches, glasses, hair pins, pacemakers, bone plates and screws, etc.) before entering the scanning environment."
So technically they are all wrong and the question should be omitted.

Correct answer is A. Hypersomnia is excessive sleepiness. D is an unrealistic answer and A makes more sense- that a person who is really sleepy would fall asleep quickly.

Read the question carefully:
Zoe, an elderly woman with a pacemaker needs to have a brain scan to investigate a possible brain abnormality. If her neurosurgeon wants to investigate the funtion of Zoe's brain, but avoid using invasive injections, which would be the best technique:
CANNOT be MRI or fMRI due to pacemaker.
CANNOT be PET as it involves the injection of a radioactive glucose solution into the bloodstream.
brain scan to investigate a possible brain abnormality- CT provides information on the size and location of brain abnormalities- CT is the best possible answer- not the best question but my teacher is an examiner and she has told me its not being taken off the exam. the thing with some multiple choice questions is to select the BEST POSSIBLE ANSWER- might not be 100% correct- but it is more correct than the other three alternatives
-
In the last SA question (14C)
It asked what two main pieces of info must be given to participants in order for them to decide whether or not to consent to being in the study?
--- I wrote that they must be informed of the processes of the experiment and the aim of the experiment.
I also wrote they must be told that they hav the right to withdraw at any time.
i was in a hurry and im not sure if these are correct or not?????

uhoh - i had everything you put.
i was unsure because it seems ever "never" or "always" option is wrong.
i went with PET for Q13, although hopefully they take that Q out.

Well the definition for informed consent is: Participants must sign a form to show they understand the nature or the research, the risks and the requirements.
So as long as you put it nature of the research and risks and requirements you will be fine as that is two different piece of information. explaining never hurts though.
-
so have we established answer to Q39?
A or D
-
so have we established answer to Q39?
A or D
It's D as A isn't entirely correct. Never any movement of the muscles in too extreme.
Their is little activity of the muscles. It is not like you are 100% paralyzed. Muscles are atonic ... but there still is a bit of movement. I verified this with my teacher!
-
Couldn't 18 also be A) Justice? Several of the
patients cannot speak English. Dr Hart translates the consent document into the patients' first langua;ge and
ensures that it is fully explained to the patients before asking them if they wish to participate.
Since he is ensuring no one is being discriminated against and are allowed to partake in the experiment?

Please note the question said FUNCTION.
But how would your teacher know? What tripe. She wouldn't know until the VCAA meeting next week. But, no it won't be taken off the exam, but they may have to accept 2 answers.
-
possible for short answer sggested responses???
:D
-
i think there are many questions we will never be certain about untill we get our results unfortunately.
-
according to your answers i got:
17/18 for Brain and Nervous System (if Q13 is ambiguous will they give us all the mark?- none of the answers are right)
13/13 for Visual Perception
10/13 for States of Consciousness (assuming Q39 is D lol)
i hate SOC. lol go die.
so thats like 40/44 - worse than my practice exams. thats poo. i hope i aced the SA. lol
Aimee
-
UGHH I wanna redo my exam thier were a few questions where I had the right answer but doubted myself and over complicated things!! Im just praying I didint change them and ended with the right answer.
4 MCQ wrong so far and I know for SA I stuffed up quite a bit.
Hoping for an A on this exam.
-
i want atleast a B+ n this so hopefully i didnt drop too many marks in SA

CT can not examine function at all (on its own anyway). To be honest, I suspect they are going to have to give multiple correct answers or just get rid of the question altogether.
-
the definitive answer to question 13 is PET scan because the radioactive substance can be ALSO be taken ORALLY, and it's original purpose was looking at brain abnormalities.
too bad i only realized this after the exam..

BRAIN AND NERVOUS SYSTEM
Question 1: Broca's area, left frontal lobe
Question 2
a- Cannot name the object as seen in the left hemisphere- corpus callosum is severed so cannot be sent over to the right hemispshere for recognition
b- Can point with their right hand
c- cannot name the object
d- can point with their left hand (as right hemisphere controls left side of the body)
Question 3
- Self inflicted pain during control questions can artificially elevate ones baseline level
-A guilty person will show similar physiological arousal when relevant questions are asked in comparison to control questions due to them self inflicting pain which increases physiological arousal.
- A guilty person could be considered innocent as they show similar physiological arousal to relevant and control questions.
Question 4
A- Sympathetic
B- Increased heart rate, increased blood pressure
C- More blood flow to arms and legs which prepares Alyse to either escape (flight) or confront (fight) the threat.
Question 5
A
- CT uses X-rays to take pictures of your brain from different angles
- Series of X-rays are then used to make a cross section (slice) of the brain
B- CT scan repeats are limited due to the X-rays. MRI scan repeats are ok.
C- Difficulty with complex mental functions. e.g. planning, analysing, reasoning
Question 6
A- David could feel depressed.
B- The sympathetic nervous system inhibits digestion as it directs its resources to the more important task of fighting and adapting to the stressor.
VISUAL PERCEPTION
Question 7
a- draw the second balloon closer to the horizon
b- Closer trees have more perceptible detail and the more distant trees have decreasing perceptible detail
Question 8
Size constancy is the tendency to perceive an object as maintaining its size despite any changes that occur to the size of the image cast on the retina.
When we are crossing a road, we perceive the cars in the distance as maintaining their size- remaining constant size and do not see them as just small objects and start walking.
Question 9
a- Perceptual set is the readiness to perceive a stimulus in a particular way which leads you to focus on some aspects while ignoring others (selection).
b i- Context
b ii- If you see a man running on the street with a gun you feel scared. But if you see a security guard with a gun outside of a bar, you feel safe and secure.
Question 10
a- Occurs when the actual perception is in conflict with the 'objective' reality.
b- The line with the feather tails is seen as longer than the line with the conventional arrowheads.
Perceptual compromise- overall lengths of the figures are unequal and distance between the tips is unequal.
Question 11
A- Selection of participants wasn't random- not every member of the population had an equal chance of being chosen to take part in the study. Not representative of the population.
B- Not done randomly. Participants did not have an equal chance of being placed into the experimental and control groups.
STATES OF CONSCIOUSNESS
Question 12
Cognitive change: Jim's thought processes may be disorganised and less logical.
Perceptual change: Jim's sensory thresholds including pain may either be heightened or lowered.
Question 13
A i- Detects, amplifies and records electrical activity in the muscles near the eye.
A ii- Detects, amplifies and records electrical activity in the brain.
B- Little or no electrical activity (Non Rapid Eye Movement Sleep)
C- Sleep spindles- brainwaves of high bursts of frequency
- K Complexes-brainwaves of high bursts of amplitude
D- The time spent in REM increases as the night goes on.
- Nightmares occur during REM sleep so are most likely to occur towards the morning as that is when we spend more time in REM Sleep than at the beginning of the night.
Question 14
A- Participants involved in both the experimental and control conditions.
Experimental- meditate before bed
Control- no meditation before bed
B- Eliminates the effects of individual differences. In an independent groups design, participant characteristics may cause bias between groups.
Question 14
C- Be informed of the nature of the research.
- The risks and the requirements.
-
Question 41
Mel is suffering from hypersomnia.
He is likely to
A. fall asleep immediately upon going to bed.
B. have difficulty falling asleep upon going to bed.
C. experience sudden REM sleep episodes during wakeful periods of the day.
D. experience sudden NREM sleep episodes during wakeful periods of the day
To the above, the correct answer is A, the poster above me thought that it was B but that is actually insomnia not hyperinsomnia
-
Q 35 is definitely not B; it is C....i asked my teacher that ....the more different the tasks are the more easy it is to carry out. Difficult and simple are opposites; hence easier to carry out.
everything else is correct. does everyone agree?
-

Actually, automatic processes states that two easy/familiar tasks can be undertaken simultaneously. Therefore B must be correct as they are both relatively easy tasks.
-

No less errors would be made with medium and simple tasks. Difficult tasks require selective attention... so if you add in another task even if it is simple your attention becomes divided... its like driving on the road for an l-plater (difficult task)... they cant talk on their mobile phone at the same time even though that is a simple task.

Ye spot on
-
If you guys read the Grivas textbook.. It says that the radioactive glucose can be injected and then in brackets they put (or taken orally) So I'm guessing its PET, because it shows function and not necessarily requiring an injection.

Na PET involves the injection of a radioactive glucose solution into the bloodstream
-
Read the Grivas textbook again page 115
-
Ah well, we'll have to wait and see what VCAA accept.
-
Also Jessie for the selection MC, could it be D?
-
what OMG!!!!!!!! r they the right answer for sure!!!!!!!!!!
-
Read the Grivas textbook again page 115
the question says Zoe, an elderly woman with a pacemaker needs to have a brain scan to investigate a possible brain abnormality- this is something that a CT can pick up.
My teacher told me that it's rate that the glucose is inserted orally and 99% of the time, it involves an invasive injection.
-
what OMG!!!!!!!! r they the right answer for sure!!!!!!!!!!
I'm not 100% about the size constancy one but otherwise yes- gone over them all with my teacher.

Not all brain abnormalities are problems with brain structure however.

But then it says function later on in the question lol

your teacher is wrong the answer is PET
-
i have to agree with the grivas text book. it must be PET its a typical vcaa tricky question to screw people over. i think i killed the patient with the use of fMRI haha.
-
I'm actually pretty sure it was PET now since it cannot be A,C or D (for Q13) and it is true that it can be taken orally, which usually is the case for the elderly or children as it is more dangerous to them; this sucks because i lost a mark for it.
-
The more I look at Question 13, the more wrong it seems
"Zoe, an elderly woman with a pacemaker (eliminate MRI/fMRI), needs to have a brain scan to investigate a possible brain
abnormality (eliminate PET - see below).
If her neurosurgeon wants to investigate the function (eliminate CT/ MRI) of Zoe' s brain, but avoid invasive injections (most likely eliminate PET), which of the following would be the best technique for the neurosurgeon to use?"
Well Nelson says:
"PET cannot detect information about brain tissue, abnormalities or damage".
so meh, all the possible answers are shit and the question is just plain contradictory in some form

im not going to say much coz im pretty brain dead from this week, but ill add something funny..
Question 25 -
If you move an object closer to the viewer
A. it has little or no effect on the viewer's perception of the object's size.
B. it causes the viewer to perceive the object as getting bigger.
C. it changes the viewer's perception ofthe object's shape.
D. it decreases the size of the retinal image of the object.
Do u know how i figured the answer to this question? lmao.
i held up a highlighter infront of my face and pulled it in, therefore, was able to determine the answer B.
i think someone said answer was C - the shape doesnt actually change. its size does, 'apparantly.'

LMAOOOOOOO
-
the answer is actually A you greek
-
Yeah, and also both Nelson and Heinemann doesn't mention anything about injections been taken orally for the PET, so i doubt they would base their answer on a fact only stated by grivas.

So you perceived the highlighter as changing in size and getting overwhelmingly large during the exam, rather than just perceiving it as getting closer? Ok...

anyone that has used the grivas text book, look at page 187 "selection" paragraph 2.. it starts with ""the most basic form.". if you read this paragraph it indicates that for the multi-choice question 22, the answer should be D, as photoreceptors selects what wavelengths to respond to.

That's more of the "transduction" process than "selection". By the time selection has occurred, it has gone through the optic nerve to the brain already, so there's no photoreceptors involved.

that is reception.
anything to do with coding and features (feature detectors) is selection so best answer was A

Question 35 MUST be C; can someone please investigate this?

I'd imagine with option C, there would be a higher cognitive load than option B

Hey Jess,
Could the answer to Q32 be C? I'm very sure....

question 31 was B wasn't it?

The sleep wake cycle refers to NREM/REM cycle. During stage 1 NREM, you are aware of "objects and events in the external world" but at stage 3-4 NREM and definitely at REM sleep, you aren't aware of "objects and events in the external world". So C is not the answer
-
question 31 was B wasn't it?
No, it's probably A
Because the object within the triangle are distinct from each other, it isn't going to be grouped to form a triangle in the mind of a person
-
To be honest I really think VCAA screwed themselved with question 13. They want to avoid an injection while not being able to possibly undergo MRI or fMRI treatment cos of the pacemaker. Can't be CAT since it's not function....So? That answer could be B,C, or D...But since the question specifically mentioned the injection shit I reckon it'll be C or D as well.
Also with question 18 are you sure it's D, respect for persons? I thought it would be justice since it states that participants should not be treated unfairly or be discriminated against (and NOT translating it would therefore violate the principal). Ah well, maybe I'm wrong but I was swaying either side of A or D.
-
question 31 was B wasn't it?
But the objects aren't similar to each other, they possess no similar characteristics to be grouped on that basis

Yeah, hmm. The definition of 'justice' in Grivas is:
"Ensuring the benefits and burdens are evenly distributed across the target population, as well as for individual participants"
Whereas respect for persons is: "Respect for persons is demonstrated when the researcher properly regards the welfare, rights, beliefs, perceptions, customs and cultural heritage of all individuals involved in research."
based on that I think it's D. Ensuring appropriate informed consent takes place and respecting the background of the participants.

Question 16: Which of the following statements about case studies is the most correct?
A. Case studies can provide ideas for further research.
D. Results from a case study are able to be generalised in most situations.
I put D ???

It's not D, because case studies cannot be usually generalised to others.

Also can someone verify, how number 22. works
Question 22
The process of selection in the visual perception system involves
A. coding particular features of a visual stimulus.
C. selecting data in the visual field for focusing on the retina.
I first put A myself, then when I re-read it after doing my short answer. I changed it
I thought .. Coding is putting meaning to...?.. Even though it says features..
While C is correct as it is focusing on particular data ?

In the selection stage, feature detects (specialised neruons) detect certain elements of a stimulus such as line, colour, movement, ect. They do this by coding particular features of a visual stimulus. Hence it being A.

i dont like the word coding, it means to give meaning to..
i wish i went with instinct first, cause with this question and 16. i had the correct answer, but when i went back over it, i changed it, as I'm silly :(

Remember, whilst Phineas Gage may have had a pole stuck through his brain, it doesn't mean that if I got a pole stuck through my head, my personality would completely change.
Another way of thinking about this is consider me having a cold. After eating my faeces, I start feeling better. Therefore faeces can be used to treat colds.
Obviously, that's absurd. Just because I seemed to get better after being administered faeces, doesn't mean other would.

That is a very, very bizarre analogy...But we don't need to know any of this anymore because unit 3 IS OVER

the answer for 13 is B because PET scan patients can take the radiactivce substances orally in a capsule therefore avoiding invasive injections

Read the Grivas textbook again page 115
the question says Zoe, an elderly woman with a pacemaker needs to have a brain scan to investigate a possible brain abnormality- this is something that a CT can pick up.
My teacher told me that it's rate that the glucose is inserted orally and 99% of the time, it involves an invasive injection.
besides u need an injection to do CT scans

The CT scans require a noninvasive injection though-- just a contrast solution. But it only shows structure so it can't be CT.

for question 10, wouldnt it be D? because an increase in blood pressure is bad, not good. and during shock your bodys ability to cope falls below normal?

i got a few wrong.. like 4. if i do good in short answers and all my sacs are A+ .... can i still have a chance of getting A?
thanks guys.

thanks guys.
Yes of course! We don't know how many marks you can afford to lose in the exam for this year for an A+, but some years you have been able to lose 8-11 marks and still get an A+.
My opinion is that this exam was more difficult than 2008, so I think the requirement for an A+ will be lower than last year's. But that's just a prediction, i could be completely wrong.
-
for question 10, wouldnt it be D? because an increase in blood pressure is bad, not good. and during shock your bodys ability to cope falls below normal?
*BOO*
When someone surprises you like that, your blood pressure goes up because of the cortisol release right?
An increase of blood pressure isn't necessarily a bad thing, unless it is long term (so say getting to late-resistance, exhaustion stage). Whereas this is different. At shock your body initially isn't able to cope but there is a rapid build up of the mechanisms to be able to fight this virus. High blood pressure and High body temperature are known to be some of these mechanisms.
-
so the answer is D then???
-
Nit it's C
During shock, those mechanisms I described earlier aren't activated. It is only when at counter-shock where the blood pressure and body temperature increase.
-
so the answer is D then???
No, the body initially responds by dropping blood pressure in the 'shock' phase of alarm reaction. Then the body goes into 'counter shock', activates the sympathetic nervous system and causes an increase in blood pressure and body temperature

Just thought I would add about Question 13.
In the book that my school uses, there is absolutely no mention of the Radioactive Glucose being administered orally, only mentions injection.
Surely VCAA will just ignore this question.
I put D my reasoning behind it is quite weird :)
I noticed the questioned mentioned the fact that she has a pacemaker.
BUT, in the last part of the question all it mentions is without "invasive injections", so yeah.
-
i just put PET because thres absolutely no chance that the patient can have an MRI/fMRI, which is preferable over the doctor's preferences
-
Meh, if they don't give both PET and fMRI I'm going to complain to VCAA.
I've discussed this with a radiologist (brother's friend) and his opinion was that radioactive glucose cannot be swallowed by individuals undergoing a BRAIN positron emission tomography. He said this is only used for stomach/digestive system PETs. He did some research for me and said it can technically be inhaled, but the PET centre at the Austin indicate they only use injections. This information is not freely available on the net, nor is it in any VCE text books.
He also said there is a possibility that patients who have had their pacemakers inserted after the year 2000 could technically undergo an MRI/ fMRI.
They're going to have to accept both.

as orally digesting the glucose is only done for stomach scans (not brain) and an fMRI or MRI will rip out a pacemaker. no possible answer.
unless CT might be the one accepted as it shows a bit of functional information

Mm, it's definately not a good question as for brain scanning, all four options are not realistic for someone with a pacemaker, wanting functional information while avoiding an injection. PET digestion is not used for brain scanning as far as I know as it would take ages to reach the brain.

in the short answer question for the one with Sperry's research, I thought that the person will be able to NAME the image when flashed onto LEFT hemisphere as it is responsible for BOTH verbalising and RECOGNISING (both hemispheres recognise---don't they?)

What do you mean by "not mentioning people could point at it"? As in, you just mentioned "right hand" and "left hand"?
Hmm, I don't think it would be acceptable to put them in as separate answers - however you could say "participant rights, including voluntary participation and confidentiality" in one. If that's what you mean.
-
hey i was just wondering if i get 74/90 is that an A or a B+

hey i was just wondering if i get 74/90 is that an A or a B+
Hmm, you could potentially scrape in with an A, depending on the mark boundaries for this exam.
In 2007, it was an A. In 2008, it was a B+.
I'm just wondering what you specifically wrote for the first question though?
-
i said they could draw it with there left and right hand i did not read the word POINT during the exam
for that last question i just wrote it like that "voluntary participation "and confidenaly and explained them "am i wrong?? :(

Aww ok. Yeah, unfortunately for the first one it didn't really relate back to the question so I don't think they'll award a mark. Don't dwell on it too much though =)
In the last question, did you include confidentiality and withdrawal as one response? Or did you put them as separate ones? If that makes sense...

hey i was just wondering for the short ans Q6 a "What is one emotional response that David could be experiencing as a result of this intense stress" is a correct answer depression??? and for b) David is now suffering from indigestion.
In terms ofthe autonomic nervous system, explain why David's digestive system has been affected by the
intense stress. is is correct if i said that because the body is using its resorces to fight the stressor his digestion is supressed and that stimulation of the digestion is due to the PNS
thankyou
-
i seperated it i did not put it as one.. am i wrong again:(

Yes, depression is fine to put down.
Your answer to the indigestion question also seems ok, did you specify that the sympathetic nervous system causes digestion to be suppressed?

hey i was just wondering for Q4 in the short answer Explain how these physiological responses aid survival in a life-threatening situation. i said this is an adaptive respose to enhanse the persons chance to survive then went on to write about that pupils dilate to allow more light so that the brain can process more info and heart rate increase so that blood can be transported to the muscles most active...Please tell me i right:))

Another thing to think about in regards to the 'pacemaker' multi-choice question....
Zoe, an elderly woman with a pacemaker, needs to have a brain scan to investigate a possible brain abnormality. If her neurosurgeon wants to investigate the function of Zoe's brain, but avoid invasive injections, which of the following would be the best technique for the neurosurgeon to use?
A. CT scan
B. PETscan
C. MRI scan
D. fMRI scan
CT could POSSIBLY be a correct answer since it has the ability to investigate possible brain abnormalities (as the question states, which should be read carefully) and that the word 'function' in the question could possibly be used as a distractor....just an idea for you all to think about. All I'm saying is that CT does detect possible brain abnormalities and all that she needs to find out is whether or not she has a structural abnormality (and CT can do that).

Nah, the word 'function' implies a functional imaging scan would need to be utilised. CT scan and MRI scan does not show 'brain functioning' unless paired with PET or fMRI. I'm not sure, but let's stop speculating, because tomorrow they are holding the VCAA assessor's meeting for Psych and this will be discussed. So we'll know soon enough.

:O how do we know what the meeting for psych is going to be about? O:

Your teachers will be able to tell you whether or not they're accepting the PET and fMRI as an answer
If anyone's heard any news regarding this, please update

I've just had confirmation that VCAA will be accepting any answer for question 13, as none of the options were correct.

For the extraneous variable question, am I wrong if I said that the severity of insomnia was an extraneous variable and related it to the experiment? Cause what I read now it seems like they want a general extranoues variable like age, gender and unrelated to the experiment.

For that question, you need to name a extraneous variable wrt the Independent Measures Design extraneous variables that the Repeated Measures Design is meant to eliminate. I'm not sure where severity of insomnia fits into that really, since that extraneous variable would be there regardless of which Design you choose (you'd have to use stratified sampling to get rid of that variable).
-
Isn't it a participant related extraneous variable that independent groups will not eliminate? But like severity of insomnia could be controlled by having all participants be in both control and experimental? I don't know, but I'm thinking they might have wanted an extraneous variable in general, not like related to the insomnia experiment. :S

Generally speaking, the examiners would be looking for an example specific to the question at hand. And upon reflection, yeah you're right about the extravenous variable things (shows how much you can forget in 2 years :P)
Fundamentally, if you can justify why insomnia is a possible extraneous variable that Repeated Measures Design can eliminate, then you should be in the clear.

hey! just a query!.
this question :
Question 39
Recordings from an electromyograph (EMG) can distinguish between rapid eye movement (REM) sleep and
non-rapid eye movement (NREM) sleep because there is
A. never any movement of the muscles in REM sleep, unlike NREM.
B. never any movement of the muscles in NREM sleep compared to REM.
C. an increase in movement of the muscles in REM sleep compared to NREM.
D. an increase in movement of the muscles in NREM sleep compared to REM.
I said D. but The suggested answers said A. Just wondering what you all said.
I think A isn't correct because the word 'never' any moment of the muscles in REM sleep,unlike NREM sleep i think the use of never is way too strong, as psych is an inexact science and too definite? like i no the bodys muscles are paralyzed but never??
i dont know.
what you's think?
-
i thought there was facial twitching to some extent during REM sleep...

current answer is D.
It is wrong to say there is bodily movement in REM. There isn't a lot but theres a small amount.
-
I've just had confirmation that VCAA will be accepting any answer for question 13, as none of the options were correct.
Just curious, how do you come by this information? Do you know a psych assessor or...?
Either way, good news!
-
Nuh, Question 43 is D. Sleeptalking can occur in REM sleep.
-
question 43 is C not D.
Sleep talking can only occur during stages 3 and 4 of NREM and never occurs in REM sleep
I hope this is like replying -
um.
Sleep talking can occur in REM and ALL stages of NREM sleep.
It is sleep WALKING that can only occur in stage 3 and 4 sleep.
Thanks :)

this just goes to show how much of a joke VCAA is
how could they possibly let questions into exams which simply have no right answers...?!!??!?!?
really makes you start to doubt the system
-
I wonder how that question escaped all the setting panel members? :O?
-

It's true. They have had a long time to go over this exam and surely they would've spotted such an obvious error. They obviously were slack and rushed through it.
-
really makes you think...
like when theres 2 answers on MC
-
I don't understand everyone's problem. It was a great question, PET was the right answer. It actually required you to think.
You had to do function (fMRI or PET) and then you had to choose whether you would kill her with the fMRI or annoy her with the PET scan. Anyone who got that wrong is a nonce.
Now everyone who didn't bring their brain to school that day gets a free mark for it.

Grrr.
Firstly, individuals with pacemakers CAN get MRIs - there are ways around it (I know someone who was able to get an MRI with a pacemaker.)
Secondly, even if it was a 'make a logical conclusion' question (which it definitely wasn't intended to be), not enough information is provided to make a 'logical' conclusion anyway. What if she had anaphylaxis to the radioactive glucose? The specialist has clearly specified he would like to avoid an invasive injection - the invasive injection could possibly be more dangerous than an MRI (if she had a pacemaker inserted after the year 2000.)
The question was misprinted. They have discussed this at length at the VCAA's examiners meeting, and have determined that there are no correct responses to that question.
-

You have to assume they can't as that is what the coursework says.
Secondly, even if it was a 'make a logical conclusion' question (which it definitely wasn't intended to be), not enough information is provided to make a 'logical' conclusion anyway.
How do you know it wasn't a logical conclusion question? Enough information is definitely provided. You look at the information there is and come up with a conclusion. I did, and my answer was right (checked with my teacher who is also a VCAA examiner).
What if she had anaphylaxis to the radioactive glucose?
Then they would have said that.
The specialist has clearly specified he would like to avoid an invasive injection
And if they intended you to think that she had something wrong with her that wasn't mentioned in the coursework... well that would be ridiculous. They would include that information. The problem is that you're not looking at the question properly. In psychology you analyse all the information and go off what you have. The pacemaker was clearly mentioned and "anaphylaxis" was not.
They have discussed this at length at the VCAA's examiners meeting, and have determined that there are no correct responses to that question.
They took the question out but how do you know how that they decided there were no correct answers? I personally think it's because everyone was having a whinge.
Well I say if everyone else gets a free mark for whinging I should be able to get one too. It's only fair.
-
Hunter, your arrogance is astounding.
"I personally think it's because everyone was having a whinge."
This is not the official reason given by VCAA, which was that no answer is correct. You claim to know more than the VCAA chief examiner in Psychology?
I'm also going to have to warn you for your anti-social, and condescending behaviour towards others. We do not tolerate this on VN. If you wish to be a part of this community, then you are to act like a functioning, civil member of it.
FYI, people have whinged about questions before in greater numbers and these complaints have fallen on deaf ears. VCAA will only change an answer/accept more than one answer if it can see that it has made an error, as with this question.
-
I don't see how my "behaviour" was anti social and/or condescending. I merely argued my point. It seems you on the other hand are allowed to directly insult people ("your arrogance is astounding").
Even though my speculation is wrong I believe my point still stands and I don't see anything wrong with arguing it.
-
How is "everyone who didn't bring their brain to school that day gets a free mark for it" not condescending? What about "Anyone who got that wrong is a nonce."?
Those are both extremely condescending and arrogant.
As for the last sentence in your post, why would you argue something that you know to be wrong? That is just arguing for the sake of arguing. Highly anti-social behaviour.

It can be interpreted as condescending but in truth I don't feel superior to those who got it wrong and that's not what I meant. What it was me frustratingly saying that people didn't think about the question properly.
I'm saying my speculation was wrong, but the main point (about the question itself) still stands in my opinion and I don't see what's wrong with arguing it.
-
I edited my post to include another one of your insults that you cannot weasel out of.
No, but after you admitted fault, you said "my point still stands". No, it doesn't.

quick question:
The mc question:
In visual perception, what is the first process:
a) reception
b) selection
c) transmission
d) organisation
Was the correct answer b)Selection? Because from my understanding RECEPTION is the first process of "visual Sensation". and SELECTION is first in "visual perception"
is that wrong?

Your post is almost identical to one in the 'THE EXAM' topic, which people have responded to.
The mc question:

a) reception
b) selection
c) transmission
d) ??
Was the correct answer b)Selection? Because from my understanding reception is the first process of visual Sensation.
I'd like somebody to clarify this :S

correct answer is reception. visual sensation and perception are seen as one process.

BRAIN AND NERVOUS SYSTEM
Question 1: Broca's area, left frontal lobe
Question 2
a- Cannot name the object as seen in the left hemisphere- corpus callosum is severed so cannot be sent over to the right hemispshere for recognition
b- Can point with their right hand
c- cannot name the object
d- can point with their left hand (as right hemisphere controls left side of the body)
Question 3
- Self inflicted pain during control questions can artificially elevate ones baseline level
-A guilty person will show similar physiological arousal when relevant questions are asked in comparison to control questions due to them self inflicting pain which increases physiological arousal.
- A guilty person could be considered innocent as they show similar physiological arousal to relevant and control questions.
Question 4
A- Sympathetic
B- Increased heart rate, increased blood pressure
C- More blood flow to arms and legs which prepares Alyse to either escape (flight) or confront (fight) the threat.
Question 5
A
- CT uses X-rays to take pictures of your brain from different angles
- Series of X-rays are then used to make a cross section (slice) of the brain
B- CT scan repeats are limited due to the X-rays. MRI scan repeats are ok.
C- Difficulty with complex mental functions. e.g. planning, analysing, reasoning
Question 6
A- David could feel depressed.
B- The sympathetic nervous system inhibits digestion as it directs its resources to the more important task of fighting and adapting to the stressor.
VISUAL PERCEPTION
Question 7
a- draw the second balloon closer to the horizon
b- Closer trees have more perceptible detail and the more distant trees have decreasing perceptible detail
Question 8
Size constancy is the tendency to perceive an object as maintaining its size despite any changes that occur to the size of the image cast on the retina.
When we are crossing a road, we perceive the cars in the distance as maintaining their size- remaining constant size and do not see them as just small objects and start walking.
Question 9
a- Perceptual set is the readiness to perceive a stimulus in a particular way which leads you to focus on some aspects while ignoring others (selection).
b i- Context
b ii- If you see a man running on the street with a gun you feel scared. But if you see a security guard with a gun outside of a bar, you feel safe and secure.
Question 10
a- Occurs when the actual perception is in conflict with the 'objective' reality.
b- The line with the feather tails is seen as longer than the line with the conventional arrowheads.
Perceptual compromise- overall lengths of the figures are unequal and distance between the tips is unequal.
Question 11
A- Selection of participants wasn't random- not every member of the population had an equal chance of being chosen to take part in the study. Not representative of the population.
B- Not done randomly. Participants did not have an equal chance of being placed into the experimental and control groups.
STATES OF CONSCIOUSNESS
Question 12
Cognitive change: Jim's thought processes may be disorganised and less logical.
Perceptual change: Jim's sensory thresholds including pain may either be heightened or lowered.
Question 13
A i- Detects, amplifies and records electrical activity in the muscles near the eye.
A ii- Detects, amplifies and records electrical activity in the brain.
B- Little or no electrical activity (Non Rapid Eye Movement Sleep)
C- Sleep spindles- brainwaves of high bursts of frequency
- K Complexes-brainwaves of high bursts of amplitude
D- The time spent in REM increases as the night goes on.
- Nightmares occur during REM sleep so are most likely to occur towards the morning as that is when we spend more time in REM Sleep than at the beginning of the night.
Question 14
A- Participants involved in both the experimental and control conditions.
Experimental- meditate before bed
Control- no meditation before bed
B- Eliminates the effects of individual differences. In an independent groups design, participant characteristics may cause bias between groups.
Question 14
C- Be informed of the nature of the research.
- The risks and the requirements.
Do you think there's any chance of an A+ with those answers?
I think I got 43/44 for the multiple choice.
