Q 35 is definitely not B; it is C....i asked my teacher that ....the more different the tasks are the more easy it is to carry out. Difficult and simple are opposites; hence easier to carry out.
everything else is correct. does everyone agree?

Actually, automatic processes states that two easy/familiar tasks can be undertaken simultaneously. Therefore B must be correct as they are both relatively easy tasks.

No less errors would be made with medium and simple tasks. Difficult tasks require selective attention... so if you add in another task even if it is simple your attention becomes divided... its like driving on the road for an l-plater (difficult task)... they cant talk on their mobile phone at the same time even though that is a simple task.

Ye spot on

If you guys read the Grivas textbook.. It says that the radioactive glucose can be injected and then in brackets they put (or taken orally) So I'm guessing its PET, because it shows function and not necessarily requiring an injection.

Na PET involves the injection of a radioactive glucose solution into the bloodstream

Read the Grivas textbook again page 115

the question says Zoe, an elderly woman with a pacemaker needs to have a brain scan to investigate a possible brain abnormality- this is something that a CT can pick up.
My teacher told me that it's rate that the glucose is inserted orally and 99% of the time, it involves an invasive injection.

I'm not 100% about the size constancy one but otherwise yes- gone over them all with my teacher.

Not all brain abnormalities are problems with brain structure however.

But then it says function later on in the question lol

[jessek]

your teacher is wrong the answer is PET

i have to agree with the grivas text book. it must be PET its a typical vcaa tricky question to screw people over. i think i killed the patient with the use of fMRI haha.
