If N1 is primarily alpha waves, as we transitioned into N1, wouldn't the emerging patterns be alpha waves? You're approaching the question as if you were in the middle of N1, "what are the next waves to emerge?", however, I think the word 'emerging' implies that we're beginning N1. What do you think? I see your issue, though, it's a poorly worded question.

[Vermilliona]

Well it's not as if you go from being completely alert (beta waves) straight to Stage 1, isn't there the awake and drowsy stage in between, where alpha waves begin to emerge? Because on another question, Susie something or other was 'awake and drowsy in class' (classic), and they asked what her brainwaves are, with the answer being alpha. So, the way I see it, alpha 'emerged' in the awake and drowsy stage, in Stage 1 they're already an established fact, it's theta waves that make the difference. I'm irrationally angry about this :/

[brenden]

Yeah look I agree with you, true alpha waves would definitely emerge in a hypnagogic state . Tbh, don't expect much of the old exams. Pre-2011 they're significantly easier (in a stupid way) and  not written as well imo.

Hey guys I was just wondering, it says that my next psych sac is a visual presentation sac, what does this mean?

Is this for unit 1?

[Michael Scofield]

Is this for unit 1?

Nope, 3

[brenden]

Is this for unit 1?

You do a presentation showing a folio, an A3/A2 poster or something, a power point etc etc.

Just a question:

During a game of squash, Andrew is hit in the left eye with a squash ball. His doctors says his sight will not be affected but he will have to keep the eye bandaged for a few weeks. With his left eye covered, information from Andrew's right eye will be processed in the:

A: Occipital lobe of the left hemisphere
B: Occipital lobe in both the right and left hemispheres
C:Temporal lobe of both the left and right hemispheres
D: Temporal lobe of the right hemisphere

Thanks

I'm pretty sure it's A, as information from the left visual field is processed in the right eye and vice versa.

[Paulrus]

actually, that's a pretty tricky question, but the answer is B. each eye is split into the left and right visual fields - the visual information from the right visual field goes to the left hemisphere, and the information from the left visual field goes to the right hemisphere. so if his left eye is covered, his right eye still registers information from the left and right visual fields, which means it'd be processed in both hemispheres, specifically in the occipital lobes. so B is the right answer

Yeah I thought it was B as well.

Left half of each eye (which receives info from the right half of the visual field) send info to the primary visual cortex in left occipital lobe and vice versa

Hey does anybody know why electrodes are usually placed under the chin when using the EMG?
 
Also regarding the GSR i dont understand this: when we experience heightened emotions we decrease the resistance and increase the electrical current of the skin.
What does it mean by the resistance?

The chin experiences like the most muscle tension during non-REM sleep for memory. Don't need to know this though, well not really.

You don't need to know that. All you have to know is that the GSR measures the electrical conductivity of the skin. The more you sweat, the more electrical conductivity that will be measured, thus giving a higher GSR reading.

oh ok, cool thankyou!

Just something I wanna clear up that I've been meaning to since forever but have only thought to post here now before a SAC:

When they tell you to state the IV, do you write mentioning both the experimental and control condition state of the IV or just the experimental condition?

That probable doesn't make much sense, so example time. Say the experiment is studying the effects of sleep deprivation on memory. Would the IV be "sleep deprivation/being sleep deprived" or "whether participants are sleep deprived or not".

Or are both acceptable? Thanks!
