Its B right hemisphere..as all those listed above are specialised functions of the right hemishpere.

[moshi]

lol i guess it was fairly obvious to you - what tripped me up was the 'understanding language' part, as i thought it was a left hemispheric function, and so i couldn't decide whether it was B or D =="

[daniel99]

Yeh thats what i didnt get, maybe recognition of language?

[extra-UNcool]

just wondering becaue i've read different info from different sources, but what is the sleep cycle exactly?

i was told that you go from stage 1 NREM down to stage 4 NREM and then back up to stage 3, 2 NREM and straight to REM. so you only go through stage 1 NREM once throughout the whole night and then REM sleep replaces it every time after that. the text book diagram looks like that's what it's trying to imply, but other sources have stated that stage 1 NREM occurs every time before REM sleep?

can anyone clarify this for me =]

oh, and good luck with the exam on thursday~

stage 1 NREM only occurs once throughout the night - after the first sleep cycle, it goes straight from stage 2 NREM to REM sleep

Could anyone please explain; weber's law? or something like that..

[psychlaw]

Webers law is to do with the differential threshold....

I'll start by explaning the differential threshold. It refers to refers to the minimum amount of change in the intensity of a stimulus for that change to be detected, 50% of the time in ideal conditions

Webers law states the the intensity of a stimulus must either increase or decrease atleast 1/60th of its original stiumlus, in order for the change to be noticed in the stimulus

i think what webers law is primarily saying is that a change of 1/60 can mean the difference of being able to see the object or stimulus that 50% of the time. And i think its 1/10 for hearing. The whole concept is about the 'just noticeable difference'. Although not that sure if my answer is 100%

hey guys does anyone have predictions as to what diagrams we may be given to label.

im guessing either a brain diagram, an eye diagram, a retina diagram or a gas diagram. Am i missing anything else we could be possibly given? Although the brain has been done in 06 i think. i hope we are not asked any in depth eye diagrams to label.

[daniel99]

The GAS was in 04 and was answered really badly.

The brain won't happen again- it was in '06 and it was ridiculously easy! I would highly doubt that they would give you an eye diagram- you're not really supposed to know the eye in that much depth anymore.

I'm doing this trial exam at the moment, it's published by Lisachem materials. anyone know of it ?

it's quite hard in my opinion.. would be great practice.

Yeah I did them last year. They offer a good gauge for performance.
