Hi everyone,
Given that the psych exam is less than two weeks away I thought I would create a thread to deal with specific questions or issues that arise during your final days of study. I am sure that myself and Eriny will endeavour to respond to any questions you have as quickly as we can.
Good luck and don't hesitate to post your thoughts and questions :)
-
ohh good idea
i got one:
from the TSSM 2007 exam:
Question 15
Neurons that pass information from the peripheral nervous system to the central nervous system are called:
A. Sensory neurons
B. Afferent neurons
C. Reflex neurons
D. Motor neurons
I chose answer B, however the answers to the exam said answer A was correct. I thought sensory neurons and afferent neurons were one and the same? (i chose answer B though cos it was most correct :-\)
-
Yeah it's a stupid question. Both A & B are correct, they're the same thing.
Sensory neurons=Afferent neurons
Motor neurons=Efferent neurons
Afferent/efferent neurons are probably regarded as outdated terminology, they prefer you to use the terms sensory and motor neurons.
-
There was a great mnemonic to do with that: SAME (sensory afferent, motor efferent).

Funny, i actually learnt that technique at a TSSM lecture.

i also learnt that at the free VIC uni lecture :)

It would be sensory as the PNS only sends sensory info to the CNS, as it cannont sent Motor info, however, it can only RECEIVE motor info from the CNS. (hope that makes sense.
Basically, sensory is going to the brain and motor is coming from the brain to a specific body part.Therefore A is the only correct response.
-
i remember sensory and motor neurons by:
efferent (effort)=motor because it requirea effort..hehe
afferent = sensory cos it's the other one lol.
pretty shit but i understand
-

I was about to post that myself! It's a very, very useful acronym.
-
do we need to know anything about white matter and grey matter
and nylon sheaths or something like that
and axons?
i hope not cause its not on the study design and if it is i know nothing about them!
-
psychlaw,
No, you don't technically need to know about white and grey matter- they were part of the study design years ago.
And no, you don't need to know about the anatomy of a neuron (myelin sheath/axon).
-
is that assumed knowledge from unit 2? my school made us look at a chapter from the unit 1/2 book about the axons, dendrites and somas for holiday homework
-
No it's not assumed knowledge. You not required to even complete unit 1 or 2 before tackling unit 3/4.
-
lol i realised that, as i didn't do 1/2 last year - i've just seen questions on practice exams about 'grey matter', so i thought we might have to know it
-
If you know why it's grey (i.e. the presence of many call bodies), then that would be ample knowledge.
-
thanks eriny (:

Guess the answer to this-
VCAA 2006
Q6-M/C
Tony is looking straight ahead at a projector screen. His right eye is covered with a blindfold. An image of a penguin is projected onto the middle of the screen.
The information would be registered in ___________ hemisphere(s).
A. The right
B. The left
C. Both the left and the right
D. Neither the left nor right
the answer is actually C - I know this may look like a simple question but the whole thing about left controls right and right controls left confused me. Although it could just be me, im not the brightest in the bunch :D
-
it's C, i think it's because although the information is flashed towards only one eye, regardless of whether the image is received by the left or right side of the retina, both hemispheres process the information
it would only be received by one hemisphere if the person had gone split brain surgery...i think
-
Nah, I think it is because of the visual fields. The left visual field goes to the right eye, and the right visual field goes to the left eye.
However the visual fields overlap... so the left eye would receive information from both the left AND right visual field, therefore information goes to both hemispheres.
If it asked "If an image is flashed to his left visual field, which hemisphere of the brain would this be processed in?" then the answer would be the right hemisphere.
There is a difference between the visual fields and the eyes... so just be careful on this one.
-
umm i thought what moshi said was to be correct. that if something gets flashed to one visual field, its processed in both hemispheres, unless they have a split brain. my teacher clearly stated this.
hope she was right
-
have a look at this website...
http://www.e-advisor.us/visual_fields.php
it explains visual fields. Eriny posted this is the psych resources section.
Hope it clears it up for you. I thought what I said was right, but if your teacher has said differently then maybe not.
-

It's a little confusing at times but you're essentially correct.
The important things to remember about the neural pathway of visual information is the following:
*Visual information from the "outer" half of each retina does not cross over between hemispheres.
*Information from the left visual field falls on the right side of each retina and ends up in the primary visual cortex in the right hemisphere.
*Information from the right visual field falls on the left side of each retina and is processed by the left hemisphere.

Ah good. I got a bit confused with that all at the time. But I think I get it now :)

well close enough...

Hmm while I'm here, something I have really struggled with is providing a concise explanation for WHY the Muller Lyer Illusion occurs, in terms of the apparent distance hypothesis, or the perceptual compromise theory. Any tips?
-
lol, its something that seems so simple yet its confusing. Once you have done about 5 practise exams or more you begin to notice a pattern.
Anyway back to the question, if it had said where it is FIRST detected as i have seen in a practise exam before than it would be 'A' right?
Also if it asks where it is PROCESSED that would be 'A' as well right?.
Its just those tssm, neap and mav companies confuse the hell out of you at times. Before looking at other non-vcaa exams i would have said 'C' without hesitation. I guess its all about reading the question properly. :uglystupid2:
-
Because it goes to both hemispheres, then it would be processed in both.
Im not sure about where it is FIRST detected, but I'm pretty sure it would be both, as the paths to the brain are the same from both visual fields. I dont think they would ask where it is first detected in a question like that.
I think that would be the questions that mean they respond to the word quicker when it is sent to the left hemisphere, and pictures when they are sent to the right hemisphere?

Yes, there was a question on a VCAA exam a few years ago about response time when words are presented to the left hemisphere (right visual field) as opposed to the words being presented to the right hemisphere (left visual field). That is, the response would be elicited faster when the words are presented to the left hemisphere (right visual field).
Make sure you are very clear on the neural pathway of information- they will undoubtedly test it because students always stuff it up!
-
Just for the record- there was a question on the neural pathway of visual info on last year's exam- almost 50% of students chose the incorrect alternative. This significantly increases the likelihood of a similar question on this year's exam. The question read:
Visual information received by the right eye is processed in the:
a) parietal lobe of the left hemisphere only
b) occipital lobe of the left hemisphere only
c) parietal lobe of the right and left hemispheres
d) occipital lobe of right and left hemispheres
The answer is D.
The examiner's report stated;
Images falling Images falling on the left side of each retina are processed in the left occipital lobe and images falling on the right side of each retina are processed in the right occipital lobe. Almost half of the students chose the incorrect alternative B.
This question was similar to Question 6 on the 2006 paper, which was also poorly answered.
Hence, it will be tested again.
-
Yeah, it was reading the examiners report that made me go back and revise that!
It's a bit confusing to get your head around it at first, especially as it's not really explained in the text book...

Question:
What is the colour of the cerebral cortex in a clear, intact brain

Question:
What is the colour of the cerebral cortex in a clear, intact brain
lol grey?
not 100% sure, as i dont really think its knowledge to be tested on :P
-
grey would seem to be the answer (its what I put)
but for some reason its put as pink in the answer sheet...
exam mistake?
-
I did that exam aswell and saud grey. Dont know why it is pink:S
-
if you're asked to give an example of a gestalt principle, could you draw one and explain it, or does the answer have to be a worded description only?
-

is that in the stav 2008 trial exam?
-
if you're asked to give an example of a gestalt principle, could you draw one and explain it, or does the answer have to be a worded description only?
On the 2006 exam report it said that the best answers describing the gestalt principle of similarity used picturs to describe what they were saying and you could also use examples for cntext e.g.
A
12 13 14
C
-

No, drawing is fine, especially if you were asked to give an example of a Gestalt principle. Doing a drawing in addition to your written response is also fine for any question on the exam.
-
could someone PLEASE write/define the Ames Room illusion and the Muller Lyer illusion and relate it to the apparent distance hypothesis (Richard Gregory)????
I know all the information but when i write it, it doesnt seem clear, and for someone reading it im sure it sounds even worse!
-
It is pretty hard to explain both the illusions succinctly and relatively simply, but here are the definitions I would use to describe them in terms of Gregory's appararent distance hypothesis.
MULLER LYER
Remember these two points:
a) Both lines cast identical sized retinal images (or in other words, both lines are equal in size)
b) the lower line (feather tails) is misperceived to be more distant and the more
distant object (feather tails), casting the same sized image, is misperceived to be longer than the arrow heads.
-
THE AMES ROOM
With the Ames Room remember the following;
a) the perceived rectangular shape of the room is consistent with the retinal image, but not consistent with the room's real shape.
b) The back corners of the room actually produce equal sized retinal images because the vertical length of the further left corner is double the length of the nearer right corner. Therefore the visual angle (or slope, can't remember) is the same for both corners from the observer's view.
c) Because the viewer does not have the depth cues to discern the real difference between the two corners, the equal sized retinal images of the corners are interpreted as equal in size, producing an illusion of a rectangular room.

awesome, thanks! this was the answer i was hoping for, will make things a lot easier.
-
thanks nick, but i have an idea of that, i just dont get how the theory is applied to the ames room. As the shorter line is proposed to be an outer corner of a room (arrow head line) how does it apply to Ames?
The reason i dont get it is because there are no outward corners (if viewing the Ames room through a monocular peephole) and all the corners of the room would therefore be the feathertail line?

My teacher also told me that people had drawn the Ames Room on previous exams! I think it would be more to help them with the response though and not part of their answer.
-
The apparent distance hypothesis can have a variety of implications and both the illusions don't possess an identical relationship with the apparent distance theory. Similarly to the Muller Lyer illusion, the Ames Room is dependant on the fact that due to its design, both corners cast exactly the same retinal image (this fits with the apparent distance theory). Because we don't have the depth cues to discern the actual distance of the corners, we perceive the room as being rectangular (this can be explained in terms of the apparent distance theory, in that both corners cast the same retinal image). Does that make sense?
-
I liked this question so i thought id post it:
Most of the photoreceptors that are responsible for colour vision respond best to:
A. Electro-magnetic radiatoion of approimately 360 nanometers wavelength
B. Electro-magnetic radiatoion of approimately 500 nanometers wavelength
C. Electro-magnetic radiatoion of approimately 560 nanometers wavelength
D. Electro-magnetic radiatoion of approimately 720 nanometers wavelength

i think that you might be getting confused between the apparent distance theory and the carpented world theory
the carpented world theory only applies to the muller lyer illusion, in which the feather tail and arrow head ends are viewed as corners of a room (outer corner - further away, against a corner which is perceived as closer to the viewer)

It's a pretty obscure question, you wouldn't be required to know the visible spectrum of light in that much detail.

Well they are all colours and cones respond to all colours lol so i would have no idea? I would say A (if it was on the exam)

correct! :smitten:
The exam review sais 'both medium-wavelength cones and long wavelength cones respond to wavelengths of around 560Nm. -so the majority of cones respond best to these wavelengths.'
moshi it's from a 'trial for teachers' exam that my teacher gave me. unfortunatly i dont have a scanner and have written all over it otherwise i would have put it up....
-
Could I have a copy anyway? LOL
When you get around to scanning it of course..whenever is good.
edit: I skipped over the bit where you said you don't have a scanner haha
-
560 nm green, the middle colour of the rainbow
it makes sense :P
-
True, but cones are known to respond best to the middle-->long wavelengths of light.
-

yeah sorry about that. That was probably the hardest/most obscure question in the exam (obviously i got it totally wrong lol). The only other multi i got wrong was relativly simple but i will post that anyway (it's filled on my pc under -stupid mistakes)
James is taking his first driving lesson in a manual car, which of the following is NOT likely to be true
A. James finds it difficult to judge the passage of time
B. James finds it difficult to hold a sensible conversation with the instructor
C. At the end of the lesson, James finds it difficult to remember features of the of the buildings they have passed
D. At the end of the lesson, James can recall all the features of the route they have taken
enjoy!
-
A
-
i'm guessing... C
EDIT: whoops, i didn't read the question properly - the not makes a huge difference, doesn't it :S (A, because he's not in an ASC and can still judge time)
-
A
A and C are both incorrect.
The correct answer is D.
-
really?
is there an explanation as to why it's D in the solutions booklet?
-
Yeah, I thought it was fairly dodgy given that the alternative suggested that he could remember ALL features of the route.
In the exam, always be wary of alternatives which suggest terms such as "all", "always" etc.
-
really?
is there an explanation as to why it's D in the solutions booklet?
There's a great deal of common sense involved with the question. Given that he is undertaking his first manual driving lesson, what are the chances of him remembering ALL feaures of the route taken? Absolutely none.
-
oh NOT likely to be true
wow that question is so obvious
LESSON LEARNT: ALWAYS READ THE QUESTION CAREFULLY
-
really?
is there an explanation as to why it's D in the solutions booklet?
nothing of any substance. 'obviously this is a complex task-a controlled process requiring selective attention and therefore he is unlikely to have noticed anything except the focus of his attention'

I would say D as it is illustrating selective attention and controlled processing. He is focusing on driving, which is a controlled process, and in focusing on driving he would not remember the route as he is focusing on driving which required high levels of attention and awareness so therefore he cannt pay attention to other stimuli e.g. the route they took?

i disagree. it does not specify the length of the journey so you cant really use that generalisation, although compairing to a,b and c it is 'the best answer' but not necessarily correct in it's entirety.
I would take the philospohy of daniel99's answer...

im having trouble understanding this association area thing.
i know that for vce psych we dont need to know all of the areas but what are we required to know?
-
im having trouble understanding this association area thing.
i know that for vce psych we dont need to know all of the areas but what are we required to know?
I had trouble with this but it just basic stuff after you know it:
Frontal lobe;
-Higher mentalfunctioning such as planning organising etc
-personality
Temporal lobe;
-facial and object recognition
Occipital;
-Sight, reading and so on
Parietal;
-Spatial ability and so on
-
is that all we need to know?
i thought the association areas were things such as the pvc and the pac or am i wrong?
-
Whats the PVC and the PAC?
Association contain neurons that are neither motor or sensory in function. I doubt that we need to know much on it..
-
primary visual cortex
primary auditory cortex.
-
NO NO NO....They are the Cotrex's within the lobes. Each lobe contains a sensory or motor cortex.
The association area's are everything other than motor or sensory neurons, basically, the rest of the brain (other than the primary cortex's).
The association areas integrate the information of all lobes of the brain..I can send you some notes regardhing them if you like?
-
im so stuck on visual perception. i dont understand it one bit. i just did 25 mutliple choice questions on it and got 7 right. from brain and nervous system i got them all right :) lol.
does anyone have easy to understand notes on visual perception? its just not sinking in:(
ive got Erinys notes and there great but i dont know what happens when it comes to questions.
so any extra info would be greatly appreciated
thank you

Hey guys,
can some one please explain the visible light spectrum thing and what i must know about this. The teacher skipped this and never ended up teaching us about this fully. All i do know that kind of relates to this is that colours remain just as bright in darkened conditions. So yeah, some basic explanations would be helpful. :)

All i do know that kind of relates to this is that colours remain just as bright in darkened conditions. So yeah, some basic explanations would be helpful. :)
what you need to know (basically):
-range of the visible light spectrum and their corresponding wavelengths (~380nm - ~760nm)
-380nm corresponds to light of VIOLET colour; 760nm corresponds to light of RED colour (think of ROYGBIV --> colours of rainbow)
-cones respond best to red/yellow light; rods respond best to blue/violet light.
thats about it :)

what ar eyou having trouble with?

i have a question:
when the question asks "with reference to ________ explain blah blah blah", do you specifically have to state what they want you to reference?
for example, if the question was "with reference to the apparant distance theory, explain how the muller lyer illusion works", do you specifically have to say "apparant distance theory" or is it assumed?
-
It would be advisable to state the term "apparent distance theory". A definition in this case could be appropriate.
For example you would say, "according to the apparent distance theory..."

okay thats very helpful but can you explain what the core meaining that i am meant to grasp from the spectrum thing. As in how is it relating to the topic or what VCAA wants us to understand about this? lol, i have never really heard about this sepctrum thing until about 3 days ago. :o
-
can u abbreviate terms like CT FMRI EEG etc or do you have to write it fully?

Yeah that's fine to do that.

if a question asks you 'what is consciousness?', do you have to mention the word internal?
this is my definition: consciousness is the awareness of objects and events in the external world and of our own existence and mental processes at any given moment
one of the teachers at my school said that it's important to mention internal, but i'm not sure how picky the examiners are going to be if i don't, as i've already mentioned 'mental processes' anyway
-
I think that you have mentioned internal as 'mental processes' so thats fine.
My definition is consciousness is the awareness of internal and external stimuli at any given moment including thoughts, feelings, sensations and memories.
But your def. covers everything so you should get full marks if it happens to come up!

well, in a nutshell, just know that electromagnetic energy lies on a continuum, from extremely extremely small wavelengths (gamma rays and stuff) to really really massive wavelengths (think football fields long). we can only see a TINY proportion of this continuum, and it is referred to as the VISIBLE SPECTRUM (~380 - ~760nm wavelength). if we could see the whole spectrum of electromagnetic energy, we would see radio waves flying about, x-rays etc etc.
honestly, i doubt you need to know so much about all this. just know the points i mentioned before and it should be sufficient knowledge.

-range of the visible light spectrum and their corresponding wavelengths (~380nm - ~760nm)
-380nm corresponds to light of VIOLET colour; 760nm corresponds to light of RED colour (think of ROYGBIV --> colours of rainbow)
-cones respond best to red/yellow light; rods respond best to blue/violet light.
thats about it :)
okay thats very helpful but can you explain what the core meaining that i am meant to grasp from the spectrum thing. As in how is it relating to the topic or what VCAA wants us to understand about this? lol, i have never really heard about this sepctrum thing until about 3 days ago. :o
well, in a nutshell, just know that electromagnetic energy lies on a continuum, from extremely extremely small wavelengths (gamma rays and stuff) to really really massive wavelengths (think football fields long). we can only see a TINY proportion of this continuum, and it is referred to as the VISIBLE SPECTRUM (~380 - ~760nm wavelength). if we could see the whole spectrum of electromagnetic energy, we would see radio waves flying about, x-rays etc etc.
honestly, i doubt you need to know so much about all this. just know the points i mentioned before and it should be sufficient knowledge.
cheers ;) that helps alot, i just got a little shoked when i heard it being mentioned in a lecture and thinking to myself i have never learnt about this. lol again thanks :)
-
Do we need to know what primary/secondary depth cues are? I stumbled on the term in a non-vcaa practise exam and I've never heard of the terms before. ???
-
Primary(internal):
Accommodation, monocular.
Convergence, binocular.
Retinal disparity, binocular.
Monocular pictorial cues;
linear perspective
height in the visual field
interposition/overlap
relative size
texture gradient
These are very important for AOS 2 and im 100% sure that they will come up on the exam!!!
-
Depth cues (classified as either monocular or bionocular) will definitely be tested, but you are not required to know them in terms of whether they are primary or secondary- this is terminology from the old study design.
-
Ah thank you for clearing it up. :) I know the depth ques but I wasn't sure which ones went under which term.
-
But its always good to know what they are under e.g. If you got a question what is the primary monocular depth cue?
Know the pictorial depth cues well as they always come up in the exam.
-
But its always good to know what they are under e.g. If you got a question what is the primary monocular depth cue?

It's very unlikely that they'd use the terms "primary" or "secondary" but it's possible I suppose. Technically they're not allowed to though.

What are some advantages and disadvantages of:
(a) Random Sampling

What exactly do we need to know about the Central Nervous System?
-
What exactly do we need to know about the Central Nervous System?
Just know that the CNS consists of the brain and spinal cord, coordinating and controlling the major functions of the body. Receives sensory information from the body (via sensory neurons) and transmits information via motor neurons to the PNS which in turn, activates muscles.
It'd also be helpful to know that the spinal cord connects the brain to all areas of the body.
The term "CNS" also indirectly relates to knowing all about the brain and all of the lobes/functions (although it's not under the "CNS" dot point)

(c) Independent Groups
(d) Matched Participants
(e) Repeated Measures
(f) CT Scan
(g) PET Scan
(h) ESB
(i) EEG
(a) Random Sampling
Advantage; quick
Disadvantage; may not be representative
(b) Stratified Sampling
Advantage; representative
Disadvantage; takes longer to create
(c) Independent Groups
Advantage; eliminates order effects
Disadvantage; requires the most participants
(d) Matched Participants
Advantage; eliminates extraneous variables
Disadvantage; time consuming
(e) Repeated Measures
Advantage; less participants needed
Disadvantage; order effects can occur
(f) CT Scan
Advantage; shows structural abnormalitites, such as strokes, tumours etc
Disadvantage; Does not show the functions of the brain
(g) PET Scan
Advantage; Shows the function of the brain whilst involved in a particular activity
Disadvantage; harmful as it involves radioactive isotope
(h) ESB
Advantage; can determine what tissue is dead or alive (whilst operating) and can determine what part of the cortex is responsible for the action that it inhibits or activates.
Disadvantage; invasive as it requires the removal of the skull
(i) EEG
Advantage; can be used on children, non-invasive, shows brain activity whilst involved in a particular task, e.g. sleeping, awake and so on.
Disadvantage; most primitve technique, does not show structure of the brain or function, to an extent.
-
the radioactive form of glucose injected isn't really harmful, i think it's better to say that it's mildly invasive
-
it can be harmful so exposure must be limited as it involves radioactive glucose though cant it?
-
yes exposure must be limited, so that's another disadvantage because of the gaps between scans, thus rapid changes are harder to pick up
my teacher said that it's more correct to say that it's mildly invasive due to the injection, that's all.
i guess your answer's fine, it's just that you wrote it's 'harmful', not that it 'can be harmful' if exposed for too long, because it'd be unethical to use the PET scan if it was flat out harmful if you were injected with the radioactive substance
-
It's not necessarily 'harmful' always as such, but the use of radioactive materials must be limited as it has the potential to affect an individual’s health after exposure.
If you are not sure, use the following for a disadvantage instead:
-Extremely expensive procedure
-Requires highly trained staff
-Each individual PET scan takes around 40 seconds, so you can't take them in rapid sucession and view subtle changes.
-The image is not structurally clear.
-
can someone provide clear definitions of both placebo effect and experimenter effect?
i dont know if mine are 100% correct...
:smitten:
-
(h) ESB
Advantage; can determine what tissue is dead or alive (whilst operating) and can determine what part of the cortex is responsible for the action that it inhibits or activates.
Disadvantage; invasive as it requires the removal of the skull
Another disadvantage of ESB:
-It is difficult to generalise any data collected from ESB to the population as ESB it is not performed on 'healthy' brains, and has only ever been performed on individuals with brain abnormalities (eg. epilepsy and brain tumours.)
Also, fMRI
Advantages:
+Provides detailed images of the functioning brain
+Takes pictures in rapid succession
Disadvantages:
-Very expensive to run
-
Placebo effect- occurs when a participant's response (dependant variable) is influenced by their expectancy of how they should behave and not as a result of the independant variable (the procedure which has been administered by the researcher).
Experimenter effect- occurs when the expectations or treatment of the data by the experimenter may affect the dependant variable. This can result in biased experimental results.

i've got a question: is there a difference between selective and focused attention?
at the lecture that i went to, the lecturer said that there was no difference (she's a vcaa examiner), but on the insight 2006 exam that i just did, one of the multiple choice solutions says:
'divided, focused', whilst the other alternative that i've narrowed it down to is 'divided, selective'
and it's definitely out of those alternatives
-
As far as I am aware, there is no difference. "Focused selective attention" involves attending to some stimuli while ignoring other stimuli whereas "divided attention" refers to the ability of a person to distribute attention and complete two or more tasks at the same time.
What was the insight question?
-
Focused and selective are the same on the continuum of consciousness that i have.
-
The term "focused" is simply just a word that is used to describe selective attention.
-
just basic english eh?
i'm a bit bored lol so here's a multi for you guys to enjoy-its not very hard lol
In regards to the relationship between arousal and performance
A. It can best be described by a U curve
B. The optimum level of arousal of a simple task is low
C. The optimum level of a complex task is high
D. It can best be described by an inverted U curve
-
arrrrrrrr D?
-
Yeah it's D. It can be described using the Yerkes-Dodson law, which is illustrated by an inverted U shaped curve.
-
the question was:
peter was a great tennis fan. when watching a game on television he was talking on the phone to his friend but stopped talking when the game reached a crucial stage. in terms of states of consciousness, initially peter was demonstrating _____________ attention but then switched to _____________ attention.
a. divided; focused
b. divided; selective
c. selective; external
d. selective; divided
-
thanks nick for the clear definitions :)
^to the above:
the answer is A. they were probably trying to trick you with "selectIVE attention" vs "selectED attention" (comparable to visual CONSTANCIES vs visual CONSISTENCIES where ive seen pop up on a couple exams :))
-

Question 44
The sleep condition which is characterised by excessive sleepiness is called:
A. Insomnia
B. Hypersomnia
C. Somnambulism
D. Meditation
Question 44
Answer: A
Explanation:
The sleep condition which is characterised by excessive sleepiness is called insomnia.
-------------------------------------------------------------------------------------------------------------------------------------------
i guess the first may be a typo but what about the second?
-
First is definitely a typo! I came across that as well.
However with the second one, insomnia is characterised by excessive sleepiness, due to the difficulty getting to sleep, staying asleep, or waking up early, hence being excessively tired.
TSSM exams aren't fantastic, I have found many mistakes in them, so I wouldn't worry too much.
-
for the second question, i think it'd only be hypersomnia if it were characterised by excessive sleepness and also feelings of extreme lethargy whilst awake
-
i still believe that teh question answer to 44 is B- it has to be :P
anyway.. in a slightly unrelated topic is it just me or are the non VCAA exams harder, i mean i score better on past VCAA exams then i do on other ones. Lol, i think its a ploy to attract more business from nervous vce students. Its all a conspiracy ::)
-
lol well it depends on which non-vcaa exams you're talking about (:
tssm exams, yes
-
TSSM are very easy. STAV ones can be pretty ambiguous.
Its just so you are prepared for the VCAA ones I guess.
When you have done harder ones, you feel more confident when you get into the actual exam.
-
The answer to 44 is a typo. The answer is B- hypersomnia. I hate TSSM, they produce stupidly easy exams.
-
Have a go at this question people- very relevant, given that it is similar to a question that has appeared on VCAA exams previously.
Psychologists who conduct brain research run the risk of breaching ethical principles relating to participants rights because:
a) radioactive substances are sometimes injected into subjects; for example, during positron emission tomography
b) they are part of a research team, but are not medically qualified to administer tests such as magnetic resonance imaging
c) the risk of exposure to radiation through tests such as computerised tomography outweighs possible research advancements
d) a brain damaged patient does not have the intellectual capacity to provide informed consent to participate in a study
-
Definately not C because CT scans don't have radiation (they have an iodine substance injected)
.....
Probably not B because to my knowledge, the only brain imaging technique which requires professionals is PET (radiologists)..... But I could be wrong
.....
Probably not D because not ALL brain damaged patients would lack the "intellectual capacity to provide informed consent"
So I'm going with A
-
is it just me or are the non VCAA exams harder, i mean i score better on past VCAA exams then i do on other ones.
Yep, VCAA is easier than Neap and STAV, I'd say (haven't done any TSSMs). Yay, I guess...it's mainly because VCAA exams are (obviously) the most relevant, and don't usually have stupid questions. I think it was in a STAV that there was a 3-mark question asking why the Gestalt principles are called 'grouping principles'. Honestly...
Definately not C because CT scans don't have radiation (they have an iodine substance injected)
CT scans use X-rays taken and various angles, and thus do involve radiation...? To my knowledge, they don't involve injecting anything :S
I did this exam question yesterday, and I also concluded it was A, because I don't believe that the radiation of CT scans outweighs the benefits (a few X-rays never hurt anyone, did they?)
-
The correct answer is D. It would definitely be considered a breach of ethical principles if you were to ask a brain damaged patient to offer informed consent.
There was a similar question on last year's exam which concluded that in the case of a brain damaged patient, a psychologist must seek guidance from an ethics committee in such instances.

A CT does involve injecting a substance into the body so that the image is contrasted better against the brain and therefore the picture is better/ clearer. However, the substance is not radioactive, but they are still exposed to X-rays to produce the image.
-
ummm a bit of a stupid question considering how close the exam is but here it goes. :idiot2:
can some body please confirm for me what brainwaves occur in what stages, as in -awake, drowsiness, stage 1, stage 2, stage 3 and stage 4. Also usually stage 3 and 4 are grouped together in books, so then what makes them so different that they need their own stage?
Also is it that each stage lasts 90 mins or each cycle?
The thing is each text i look at is a little different and some combine different waves from different stages. Im just loosing my mind : :laugh:
-
awake: beta waves
relaxed (eg meditative state but still awake): alpha waves
stage 1: theta waves replace alpha waves
stage 2: theta waves + sleep spindles and possible k-complexes
stage 3: theta waves with 20-50% delta waves
stage 4: >50% delta waves.
REM sleep: beta-like waves.
each cycle lasts 90 minutes (that is, stage 1 through to stage 4 + REM sleep = ~90min)
-

"CT scans don't have radiation (THEY HAVE AN IODINE SUBJECT INJECTED"
-
i lost a mark on a practice exam that i did in class for not specifying that theta waves define stage 1 sleep, i only said that theta waves and alpha waves were both apparent in stage 1 sleep :( , so remember, it's not enough to just list the types of brain waves!
-
awake: beta waves
relaxed (eg meditative state but still awake): alpha waves
stage 1: theta waves replace alpha waves
stage 2: theta waves + sleep spindles and possible k-complexes

-
can someone give a concise explanation, that would satisfy a 3 mark question on the exam, as to why the ames room illusion occurs?
im finding it hard to keep the explanation short and succinct...
me 2....probably the only thing im struggling with:(
-
the ames room is constructed in the shape of a trapezoid. the ceiling slopes upward (right to left), so that the ceiling height is taller on the left side of the room; the left corner is double the distance away from the viewer than the right corner is, however, due to the elimination of binocular depth cues due to the monocular peephole, the back wall appears to be parallel to the front wall, as shape constancy overrules size constancy - the viewer more readily perceives people as differing in size than rooms that are not rectangular/square in shape.
(i doubt that'll fit the space allocated though)
i'm having more trouble explaining the muller lyer illusion succinctly, lol
-
can someone give a concise explanation, that would satisfy a 3 mark question on the exam, as to why the ames room illusion occurs?
im finding it hard to keep the explanation short and succinct...
This is something written by the chief assessor that would achieve three marks.
1. The room is perceived as a normal shaped room (rectangular) but is really a trapezoid. One back corner is twice as far from the viewer than the other
2. A person crossing the room changes distance from the viewer, so the size of the retinal image changes
3. The viewer perceives the person to have changed size, not distance.
You might find that useful, but personally, I prefer my own notes...
-
here's a multiple choice question that i was also rather confused with:
merle has excellent perceptual skills. she can recognise patterns, face and melodies and is very skillful at putting together jigsaw puzzles. she is also superior at understanding language and can differentiate between jokes, irony and sarcasm. which part of the brain is responsible for merle being able to perform all tasks?
a. occipital lobe
b. right hemisphere
c. frontal lobe
d. left hemisphere
-
Its B right hemisphere..as all those listed above are specialised functions of the right hemishpere.
-
lol i guess it was fairly obvious to you - what tripped me up was the 'understanding language' part, as i thought it was a left hemispheric function, and so i couldn't decide whether it was B or D =="
-
Yeh thats what i didnt get, maybe recognition of language?
-
just wondering becaue i've read different info from different sources, but what is the sleep cycle exactly?
i was told that you go from stage 1 NREM down to stage 4 NREM and then back up to stage 3, 2 NREM and straight to REM. so you only go through stage 1 NREM once throughout the whole night and then REM sleep replaces it every time after that. the text book diagram looks like that's what it's trying to imply, but other sources have stated that stage 1 NREM occurs every time before REM sleep?
can anyone clarify this for me =]
oh, and good luck with the exam on thursday~
MODERATOR ACTION: This post (which originally appeared in the exam discussion section on the forum) has been merged with this topic.
-
stage 1 NREM only occurs once throughout the night - after the first sleep cycle, it goes straight from stage 2 NREM to REM sleep
good luck to you too on thursday (:

Could anyone please explain; weber's law? or something like that..
-
Webers law is to do with the differential threshold....
I'll start by explaning the differential threshold. It refers to refers to the minimum amount of change in the intensity of a stimulus for that change to be detected, 50% of the time in ideal conditions
Webers law states the the intensity of a stimulus must either increase or decrease atleast 1/60th of its original stiumlus, in order for the change to be noticed in the stimulus
-
Could anyone please explain; weber's law? or something like that..
i think what webers law is primarily saying is that a change of 1/60 can mean the difference of being able to see the object or stimulus that 50% of the time. And i think its 1/10 for hearing. The whole concept is about the 'just noticeable difference'. Although not that sure if my answer is 100% :)

hey guys does anyone have predictions as to what diagrams we may be given to label.
im guessing either a brain diagram, an eye diagram, a retina diagram or a gas diagram. Am i missing anything else we could be possibly given? Although the brain has been done in 06 i think. ??? i hope we are not asked any in depth eye diagrams to label. :D

The GAS was in 04 and was answered really badly.

The brain won't happen again- it was in '06 and it was ridiculously easy! I would highly doubt that they would give you an eye diagram- you're not really supposed to know the eye in that much depth anymore.

whats an example of context affecting perceptual set (not bruner and mintern) a made up example
-
I used the Bruner/Minturn example on last year's exam and I got full marks. I'd stick with that one. It's the best. Or you could use this one from the assessment report..
In Loftus and Mackworth’s experiment with a picture of the giant squid outside the barn in a farmyard scene, the unexpectedness of the squid in that environment (context) meant that subjects focussed their attention on the squid and did not notice other details.

This was in the 05 STAV, i dont agree with the answer
------------------------------------------------------------------------------------------------------------------------------------------
Question 1
A patient who had undergone a split-brain operation is presented with a picture of a
yacht to his left visual field and a picture of a train to his right visual field, and is
asked to verbally report on what he sees.
i. What is he likely to report concerning his visual experience?
_____________________________________________________________________

Question 1
i. One mark
Patient will report seeing the train; he will not report seeing the yacht.
ii Two marks Give one mark for each of the following:
• The image of the train ends up in the left hemisphere. This hemisphere has the language centres and he is able to give the object a name − a train.
• The image of the yacht ends up in the right hemisphere. The visual cortex can process the image correctly but because the corpus callosum is cut, the patient cannot assess language to give it a name.
------------------------------------------------------------------------------------------------------------------------------------------
i mean if its cut how is the image of a train going to be reported verbally- the train was on the right and the brain is split; hence it is unable to verbally reported which is a left hemisphere function.
Am i wrong or is it STAV?? ???
-
STAV is correct. The train is presented to his right VISUAL field, not his right hemisphere.
When the train is presented to his right visual field, the image will fall on the left side of each retina and the image will be processed by the left hemisphere. Hence, he is able to name it because the image has been sent to the left hemisphere (the language hemisphere).
-
so do MRI scans utilise magnetic fields and radio waves to produce an image of the brain, or do they only use magnetic fields? i've got contradicting information from different sources :S
-
Magnetic resonance imaging is a technique that uses magnetic fields and radio waves to cause atoms in the neurons of the brain to vibrate. The vibrations are detected by a large magnet in the chamber that encloses the person undergoing the procedure.
-
STAV is correct. The train is presented to his right VISUAL field, not his right hemisphere.
When the train is presented to his right visual field, the image will fall on the left side of each retina and the image will be processed by the left hemisphere. Hence, he is able to name it because the image has been sent to the left hemisphere (the language hemisphere).
yeah but its the whole spit brain thing i dont get? If the brain is split how does the info travel?
-
In a split brain patient, the two hemispheres are unable to communicate with each other- they can still receive information. They simply act independently of one another. That is, if the right hemisphere is presented with visual information, the person cannot name the item because the right hemisphere can't communicate to the left hemisphere what it has seen. Does that make more sense in simple terms now?

Can u get a statement of marks for the mid year results? Or do you have to wait until the end of the year? I thought u could get them in mid year, but teachers seems to think that u can only get them at the end of the year?
-
You can definitely get them for mid year exams. I received mine about a week after mid year results came out.
-
Do we need to know about dark adaption!!?!??
-
You're not expected to, no. It was mainly a focus of the previous study design.
-
phew...
-
when/under what circumstances is deception allowed to be used in research?
-
Deception may only be used in psychological research where the study cannot continue without the use of it. However if deception is used, experimenters must debrief participants about all deception used and they MUST ensure that the participant suffers no harm due to the use of deception/
-
when/under what circumstances is deception allowed to be used in research?
when its approved by an ethics committee.
hey, vcaa accepted the answer on the exam last time! :P
anyways, go watch House. learn psych from that haha

I tried to blackmail the administrative she-ghoul that lurks in the VCE center to phone me on Sunday night and give me my results... it's just so distracting! we're not given the letters till afterschool and we've got a chem sac that day... argh that letter is all i can think about!
