True

[iNerd]

The cerebral cortex is convoluted to:
a) allow for greater volume and thus the number of brain cells to be contained
b) allows for greater blood flow to the cortex and therefore more oxygen can be available
c) allows for greater blood flow to the cortex and therefore more blood-sugars can be available
d) all of the above

Would D be correct?
-----------------------------------------------------------------------------------------------------------------

Visual images in the right visual field:
a) are detected by photoreceptors on the right side of each eye's retina.
b) are detected by photoreceptors on both sides of each eye's retina.
c) are processed in the right occipital lobe
d) are processed in the left occiptial lobe.

I'd say both A and D?

Q1 D is correct I'm pretty sure.

Q2... umm how could A be correct :S If it said the LEFT side of each eye's retina then A + D would be correct.

Oh wow I'm such an idiot. I thought right hemisphere instead of right visual field :/

I blame SAC pressure

Hey guys!

Just a quick question -

How does the serial position effect support the multi-store model of memory?

[dooodyo]

Hey guys,

What is an example of how emotional state affects perceptual set?
Any help would be much appreciated.

[Glockmeister]

Did you need to come up with something, or are you meant to find it in the article? Cause I can't find it in the article.

You're supposed to use the article/research to work it out. It's really hard!

Right.

In terms of the hypothesis, you would be able to pick a direction that want, although there is mention of past information, so make it based on the knowledge that you are given about perfect pitch etc. You need to make sure it has the standard structure of hypothesis: that is the experimental, control group and direction.

IV - Think about that the researcher is doing

DV - Think about what is the output of the experiment that the researcher has done.

Ethical Considerations - You can go with the stock standard informed consent/withdrawal rights/confidential ethical problems. I don't see any special ethical considerations needed. Make sure you explain the ethical consideration with respect to the study itself. Don't go for a generic response (most people starting out tend to do this).

Further Research - be creative. What other techniques that you have learnt could be applied to investigate that sort of problem.

Hey guys!

Just a quick question -

How does the serial position effect support the multi-store model of memory?

Clue: Think about the Primacy and Recency effect. Why does the Primacy Effect occur (i.e. why do people, when presented with 12  in a list, tend to remember the first few more than the middle few) and why does the Recency effect occur. Link this to the multi-store model of memory, particularly the memory stores.

Faces are probably the best example of this. When you are sad, you might interpret other people faces differently compared to when they  are happy.

DO DIFFERENT NEURONS SEND OUT DIFFERENT NEUROTRANSMITTERS?

FOR INSTANCE DOES THE MOTOR NEURON AND THE SENSORY NEURON RELEASE SEROTONIN/ACETYLCHOLINE... ETC?

[Russ]

Less caps. Different neurons use different neurotransmitters, yes, and it can differ between sensory and motor neurons. It's not a one size (neurotransmitter) fits all approach

[Glockmeister]

Oh definitely - and there can be differences within motor neurons or sensory neurons. It really depends on various factors like the location of the neuron (e.g. motor neurons that synapse [connect to] muscles tend to have acetylcholine neurotransmitters, whereas motor neurons found in the spine tend to have glutamate neurotransmitter), as well as the purpose of the neuron. There are some ubiquitous ones though. Glutamate for example, is pretty much found anywhere, because it's presence in the Citric Acid Cycle makes it critical for the metabolism of glucose and amino acids (you don't need to know that last sentence for VCE Psychology [although you probably do you're doing VCE Biology though])

[iNerd]

Label each of the statements as either free/serial/cued recall, recognition or relearning.

Playing HangMan. (free for the first letter correct and cued from then on? :S)

Remembering the directions to a friend's house. (cued if you pass landmarks? free if you're just reciting it?)

[Glockmeister]

Playing Hangman - I would say cued recall. It's been ages since I've played hangman, but iirc, when I used to play,  I would guess the first letter. There wouldn't really be a role for memory for that.

Remembering the directions to a friend's house - I'd say the answer is free recall. The question hasn't said anything about you actually going to your friend's house, in which case, yes you would have cues. An example of make sure you answer the damn question.

[Darren]

Can someone please outline the weaknesses of (and strengths if possible..)
a) retrieval failure theory
b) interference theory
c) motivated forgetting
