GOOD LUCK remembering to spell or remember the word for the different ways to measure consciousness.

Just as well the abbreviations are accepted - EEG, EOG and EMG are so much easier to write!

Yeah I've worked out what they mean as abbreviations but I don't know what the full words are so I could be in a bit of strife for that.

EEG - detect, amplify and record the electrical activity of brain
EMG - detect, amplify and record the electrical activity of the muscles
EOG - detect, amplify and record the electrical activity of the muscles that control eye movement.

I think that is right for them??

I've also memorised the type of brain waves (alpha, beta, theta, delta) but I'm having trouble remembering what frequency and such they are! Any tips ?

Yes, those definitions are fine

Try this: Bat Droppings - Beta Alpha Theta Delta
These are in descending order of frequency and ascending order of amplitude
If you know this, then you will be able to compare them easily if required

Hope that helps!

You're amazing! I actually remember 'BATD' coming up in class today and I wrote it down but wasn't aware as to what it was for. Have any more tricks or acronyms up your sleeve for the first AOS ? Let me have a go ..

EEG ->EEG is a devised used to DARE (acronym for previously mentioned answer) activity in the form of brain waves.

BRAIN WAVES!
Beta -> High frequency with low amplitude.
Alpha ->  Relatively high frequency with low amplitude (taller than beta though)
Theta -> Medium frequency with a mixed amplitude.
Delta -> Low frequency with a tall amplitude.

After reading my book after attempting to do that, do you need to write words like 'a steady pattern of low frequency' for Delta and such, or is what I've written good enough (or too basic).

Thanks!

Haha, glad to help!

What you have written is great, but it would be even better if you compared each brain wave to another. For example, alpha brain waves are a slightly lower frequency than beta, with a slightly higher amplitude than beta. This way you demonstrate that you understand not one, but two forms of brain waves!

For the five methods (that I have) of studying consciousness, do you need really long blocks of information like (A) or would a more simplistic approach (B) suffice when describing what they are or having to know what they are.

(A) EEG is a device used to detect, amplify and record the electrical activity in the form of brain waves. Electrodes are attached to the surface of the scalp that detect the electrical activity of the neurons in the cerebral cortex. The EEG amplifies and translates the relatively weak electrical activity into a visual pattern of brain waves which are displayed as a electroencephalogram.

(B) EEG is a device used to detect, amplify and record the electrical activity in the form of brain waves.

Thanks

Almost always would be the second option, unless the question was worth three marks or something on just EEGs, which I find improbable.

Do we need to know about demand characteristics and artificiality? I don't think it's in the study design anymore but could someone please confirm? And is operationalising IV and DV still in the year 12 course?

What are you up to??

[ealam2]

HawthornM8, we're just finishing off research methods and about to start the brain next week.

you definitely still need to be able to operationalise the IV and DV. that's come up in extended response. you won't lose marks for operationalising them if the question doesn't specifically tell you to, so if you choose to always operationalise them you'll be fine. but it's personal choice tbh

i don't think you need to know demand characteristics and artificiality as confounding variables (not 100% sure though), but you'll need to know artificiality as a weakness of sleep labs at least.

Okay. I don't mind operationalising the IV and DV. Okay: need to know artificiality.

Thank you very much!

WTF. We are on sleep. I just had a sleep measurement chapter test (not a SAC) and absolutely failed it to the max. However it was an easy test, I just don't know atm what the 4 brain waves in EEG are for, and the types of sleep and stages etc.

Are you like a 1/2'er? LOL

How long did you guys spend talking about research methods. We only spent a period.....

[Vermilliona]

We're being taught by someone who hasn't taught psych at all (even 1/2) in over 10 years. Still got another week of research methods, woop woop
