theta waves = medium freq , medium amplitude

thats what the textbook says but my lecturer notes say otherwise

[dior1]

from my understanding, theta waves = medium frequency, mixure of high and low amplitude.

[madi1234]

or just compare it to delta waves, saying compared to delta waves its higher in frequency and lower in amplitude....


(in my text book it says; theta is frequency is med-low, and amplitude is high-med)

would somebody be able to help me out with these short answer qs..

* What are two benefits of the automatic functioning of the ANS?
* Define bottom up processing as it occurs in visual perception.
* Outline the problems associated with using the repeated measures design.
* What is one main limitation of using straified sampling?

Also, when presented a question about the peephole and how it allows the illusion to work, does it want us to mention how it only allows us to use binocular cues.

(i shall add more q's if i get stuck )

[mypurpleundercracka]

*The peephole eliminates the application of the strongest binocular depth cues to judge distance and space, by applying monocular cues the room is maintained as if it were rectangular (that is the left corner being the same distance from the right) rather than its realistic trapezoidal shape

*"Order effects" may occur, that is prior knowledge/exposure to the task influences participants performance and thus the reliability of the results, boredom and fatigue may also play apart

*self regulatory and not interdependent on the CNS, person does not have to concentrate their mental effort and energy on maintaining voluntary functioning of the visceral muscles, person may be in coma yet their heart-rate and breathing will still continue


*With stratified sampling, it may be difficult and time consuming to determine, calculate and establish the necessary subgroups or proportions

ANS also increases survivial rates (fight-flight)

does anyone reckon they'll ask us a question to draw a graph on the sleeping stages or draw particular brain waves

they haven't done that before from my understanding so i assume its quite possible

[dior1]

can someody please tell me what REM rebound is? this just came up on a prac exam and it's the first time ive seen it =S

[mypurpleundercracka]

can someody please tell me what REM rebound is? this just came up on a prac exam and it's the first time ive seen it =S

excessive amounts of rem sleep occurring after a person has been deprived of REM sleep

[Poppy M]

I think that for sure they'll ask us to draw something... apparently they said at the examiners lectures that it hasn't been done and it is "quite possible" they'll include it at some point...
Drawing things is always so risky and ambiguous...

Can anyone explain the ames room in tums of apparent distance theory?
Its not clicking in my brain!!
Thanks

Lucas is dressed as a pirate and is wearing an eye patch over his left eye. Visual information that enters his right eye will be processed in his ________ lobes.
A. right occipital
B. right parietal
C. left parietal and right occipital ---> is that a typo???
D. left occipital

In the early 19th century, researchers discovered the functioning of the human brain primarily through ;
A. humans volunteering to undergo an operation
B. autopsies
C. surgical procedures carried out on animals
D. none of the above

these are from Lisachem 09 btw
thanks

[mypurpleundercracka]

The answers are

C

and

B

how they came to those conclusions i dont know, how can they discover brain function through autopsies if the person is dead like wtf

[d0minicz]

yeah man i dont get that either

hey should the first question have C as both occipitals?

[d0minicz]

dont tell me it has something to do with the dorsal stream -_-"

[mypurpleundercracka]

i know initially that info from the right eye is processed in the left occipital lobe, i don't understand how it can be C, visual info doesn't go to the parietal lobe
