<p>Q: What is the definition of circadian rhythm?</p>
<p>Another Q: Is sleep a state of consciousness? If yes, explain why.</p>
<p>^a small addition to llpitch's correct answer
EEG = records electrical activity in brain
CAT = X-rays. structure
PET = activity in brain
MRI = Magnetic resonance image. Like the CAT scan, but with better image
fMRI = the best. Can get both activity and structure at the same time</p>
<p>natural sleep cycles, I think. If allowed to sleep uninhibited the average human will have a 25-hour sleeping/waking cycle.</p>
<p>Circadian Rhythm- Isn't that the brain function that controls amount of sleep?</p>
<p>@llpitch
circadian rhythm = our biorhythm. determines when we sleep, eat, etc. Also determines if we're an owl or a morning person</p>

<p>Correct!</p>

<p>Q: Define abstract learning</p>
<p>Has anyone taken the Barrons 2008 practice tests?</p>
<p>Sleep is a state of consciousness, not sure how to explain why.</p>
<p>sleep is an unconscious state, isnt it? Though of course, REM sleep is also called paradoxical sleep since we are quasi-awake, since are brain waves are very similar to that when we are fully awake</p>
<p>@videogames -> I took the 1st barron's test... I got 63/80 right. Bombed pretty bad since I took it with no review</p>
<p>Q: Define abstract learning</p>
<p>Abstract learning is understanding complex concepts such as a tree instead of learning to press a lever to get food. Can someone provide a better definition? Barrons kinda sucks for this one.</p>
<p>Has anyone taken the Barrons 2008 practice tests?</p>
<p>I'm taking all 3 on Monday night.</p>
<p>Another Q: Is sleep a state of consciousness? If yes, explain why.</p>
<p>A (From Barrons pg. 75): Sleep is a state of consciousness because while we are asleep, we are less aware of ourselves and our environment than we are when we are awake. This is why drug-induced states and hypnosis are also considered states of consciousness.</p>
<p>I've taken the first one.</p>
<p>How'd you do?</p>
<p>Wait, 63/80 Kowloon?</p>
<p>There are 100 questions lol.</p>
<p>^Oops, I meant 63/100. pretty bad. it should be better after all this review at CC</p>
<p>Anyways, next Q
Rods and cones. Compare them. Where are they abundant? their functions?</p>
<p>Q: Differentiate between parasomnias and dysomnias and give examples of each</p>
<p>im taking a barrons practice test tomorrow..ill let you know how i do =]</p>
<p>whoa...never even heard (^) of those...</p>
<p>There are 100 questions though...</p>
<p>I got 71.25 after the penalty on Friday...however, I absolutely bombed the essay section (I grade myself pretty strictly though), I only got 3 points on each essay. So I ended up getting like one point under a 5. x_X</p>
<p>Do you think the general score range for a 5 will be 100-150, or will it be more generous?</p>
<p>Oh yeah, I've never even heard of dysomnia, so I'm interested in the answer to that quesiton.</p>
