<p>^the general range tends to be from 93-150... but yeah, a 100 is pretty much a sure '5'</p>
<p>^the mcq score is really good. On my first practice one I received a 60/100, no essays. Hoping for a 71-75 on real thing...</p>
<p>Rods and Cones are photoreceptors located on the retina in the eye.
Rods: For dim lighting, concentrated on sides of retina.
Cones: For colors, sharp vision, concentrated in center of retina, especially in the fovea.</p>
<p>Does everyone want me to post the answers to the parasomnias/dysomnias question I asked?</p>
<p>q: what is a p value and a z score?</p>
<p>So what kind of scores can we be looking at on the MC/essays in order to get a 4 or 5? My goal is a 4 or a 5 and knowing what I should shoot for would be really helpful =] Like how many correct on the MC coupled with what essay score = a 4 or 5?</p>
<p>Q: Differentiate between parasomnias and dysomnias and give examples of each</p>
<p>I've never heard of those either, please define for us =]</p>
<p>P value and Z score deal with statistics right?</p>
<p>Parasomnias involve abnormal disturbances during sleep: nightmares, night terrors, sleepwalking.</p>
<p>Dysomnias are problems with the amount, quality, or timing of sleep: insomnia, sleep apnea, narcolepsy.</p>
<p>P value and Z score deal with statistics right?</p>
<p>Yeah, a z score measures how far a piece of data is away from the mean. It's a measure of variability. </p>
<p>A p value is what comes out of an inferential stats test. The smaller the p value, the more significant the results. Usually a p value lower than .05 is considered statistically signifcant. For example, a p value of .05 means that a 5% chance exists of getting the results by chance alone.</p>
<p>I took AP Stats this year (and destroyed the AP exam =D), and it gets a lot more detailed, but for Psych you only need to know the basics like what I said above.</p>
<p>Q: Define insomnia, sleep apnea, somnambulsim, night terrors, and narcolepsy. Which would you LEAST like to have, and why?</p>
<p>@llpitch
insomnia = can't sleep
sleep apnea = ?
somnambulism = sleep walk
night terror = similar to nightmares, but you are consciously awake
narcolepsy = breathing irregularities while sleeping. circadian rhythm gets messed up, since your sleep cycle is wacko</p>
<p>Q: Differentiate between operant and classical conditioning</p>
<p>Operant conditioning is a kind of learning based on the association of consequences with your behavior. Classical conditioning is based on the association of stimuli.</p>
<p>Insomnia: problems with going to/staying asleep.
Sleep apnea: stop breathing during sleep, wake up temporarily.
Somnambulism: Er..
Night terrors: waking up, having irrational fear of something.
Narcolepsy: unexpectedly falling asleep during normal activity. Least likely to have, because it's....really rare?</p>
<p>Sleep apnea causes a person to stop breathing for short periods of time during the night. The person wakes up a little bit and gasps for air, and then contiues to sleep. Most people don't know they have apnea and in serious cases, it can be fatal.</p>
<p>Sleep apnea would be the disorder you would least like to have because it can sometimes be fatal.</p>
<p>Q: Explain taste aversion, in terms of operant conditioning and classical conditioning.</p>
<p>NVM, totally read your question wrong. Sorry.</p>
<p>I meant which would you not want to have, not which one is the least likely in humans.</p>
<p>What are the developmental stages of Erik Erikson? Do we need to know this for the exam?</p>
<p>Taste aversion occurs when a food causes one to become sick, usually with nausea. You are likely to avoid that food from them on.</p>
<p>Don't kow how to explain Using operant and Classical though</p>
<p>Yes, you do have to know the stages of Erik erikson. I don't know them 100% so I don't wanna give you wrong info here.</p>
<p>They are listed a few page or two back, I think.</p>
