Suggested solutions - multiple choice

[Glockmeister]

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

and everyone breathes a sigh of relief.

yay

[claireburum]

ps do you know what else they discussed in the meeting??

[bloodboy]

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).

[bloodboy]

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 )

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?

[d0minicz]

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.

Just curious, how do you come by this information? Do you know a psych assessor or...?
Either way, good news!

[ammuzusak]

Nuh, Question 43 is D. Sleeptalking can occur in REM sleep.

[Tashfairy]

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

[Greggler]

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

[bloodboy]

I wonder how that question escaped all the setting panel members? :O?
