[Visionz]

visionz have you written down your answers so we can compare?

for 42- I got A
because both the control (placebo) and experimental group (received herb) received different versions of the 2nd test
so the effect on the DV would maybe not have been because of the IV
it was biased
what do you think ? :S

Isn't that what I put down? A?

[psych93]

Haha oops ! Sorry about that !
You're quite right
must've been a lapse in my visual perception ...

[Glockmeister]

Would it be Past Experience or Context that is doing you in?

- I can't believe the amount of nerdy jokes I'm doing here guys.

Anyway, Short Answer question should be done by tomorrow - too tired to do them now, I had my own Psych exam to do.

[psych93]

Possibly past experience with finding discrepancies in my answers compared to yours
and short answers would be fantastic !

Question 1

I thought it was the frontal lobe on the basis of the "reasoning, planning" which I believe is a frontal lobe function.

Question 7

This is a case study. One of the limitations is that you can't generalise to a wider population because you can't follow an experimental protocol hence you can not make a cause and effect relationship.

D. it is too easy to generalise the results of this type of research.

it is "HARD" not easy to generalise...i think you misread the answers there mate..

 and cerebral cortex is also responsible for planning and reasoning...amongst many other higher mental functions...the frontal lobe is part of the cerebral cortex so whatever the frontal lobe does we can say the cerebral lobe does too.... but what gave the answer away was the 70% of neurons bit....thats why it's called the Grey area... (cell bodies)

i got 1 wrong i think...T.T

the one about what happens when your coprus callosum is cut... i choose you would have difficulty in dressing up

[Glockmeister]

Exactly, hence why I didn't choose answer D.

I don't see why D isn't the most correct answer for question 10. Split brain operations mean the right and left hemispheres can no longer communicate with each other, and so actions which require both "halves" of the body, such as dressing up will be impaired. The answer states that co-ordination of actions will be difficult, and then gives an example, which is the dressing up bit. Imo this should be the most correct answer.

it does say "CO"-ordination....

but raising you right hand and left hand to lift your pants dont need any communications with each other

[cheese360]

Yeah, but it's just an example. The key word in the answer is co-ordination.

do we know the answer? or is everyone just speculating?

[cheese360]

I guess I can ask my teacher in class tomorrow.

Thank you. Someone who finally agrees with me. Hopefully we're right.

I don't think anyone has said that you're wrong. I put that aswell but after looking it up on wikipedia (not in the textbook at all) it says memory is lower but coordination is the same.

It's a weird question that I don't think is part of the study design.
