I advise you to read very carefully.

If you still don't see your error then post again.

Ah right, a friend just explained to me about the half of each eye and so on... we have not been taught that .... at all... so yea i thought wrongly... sorry...

and Thanks sSnaKe!

@pilky01, Thanks for explaining it.

Question from LisaChem 2009:

Encoding is the control process that:
A - Maintains information in working memory
B - Maintains information in sensory memory
C - Transfers information from sensory to working memory
D - Transfers information from working to LTM

The answers is D, but couldn't it have been both C and D? ..
thanks.

Pretty sure sensory to working only involves attending to it, so it would would be D as it actually encodes the information from STM to LTM

It could be C as well, however to get sensory memory into working memory, you're just paying a bit of attention to it (not really a control process) but to encode info from working memory to LTM, you're actually actively encoding it and putting more focus into it (through means such as elaborative rehearsal) so maybe that's why it was D??

Is "Chunking" the grouping of smaller bits of information into a single larger chunk? or grouping bits into smaller chunks? Grivas' book says it's "smaller bits into a larger single unit or chunk" but the definitions are varied amongst the exam solutions :/

Thankss

[Darren]

No. Chunking is grouping smaller bits of information into a larger, single unit which represents many pieces of info to increase the capacity of STM.

Can anyone please explain the progression of alzheimers? What type of memories are affected first and last?

Can anyone please explain the progression of alzheimers? What type of memories are affected first and last?

Usually in Alzheimer's disease, first recent memories are affected (like what you ate in the morning), then episodic memories, then semantic, and last is procedural. A lot of people pass off "forgetting what someone told you yesterday" as a normal sign of ageing, but it could actually be an early sign of Alzheimers

Recent memories are episodic memories. Be very careful in how you word that on an exam.

Yo!
Are we going to be required to be able to fully label a diagram of a neuron (dendrites/myelin sheath/axon terminal etc..) on our upcoming exam?

After being stumped on a practice exam I tried to touch up on my knowledge and was wondering what everyone else has heard regarding it.

Cheers

It's pretty simple to know the basic diagram, im sure you could spend a minute learning it heh (dendrites=branches, mylen sheath=covering of axon, axon terminal=endings of branches, etc...)

Would a change in self-control for an altered state be a physiological characteristic? (like for example, being influenced to suggestion by others)

No. Psychological.

No. Psychological.

What about 'changes in self control' in the physical aspect? like not being able to control and coordinate movements properly??

[Zafaraaaa]

When we talk about the processes of movement, sensation and stuff; what -exactly- should we mention? And when talking about sensations, do we need to also always talk about the work of the thalamus in relaying sensations to the cerebral cortex??? :/

Is this a sufficient answer to show what happens when we want to kick a ball? :/
The brain sends out motor messages (in the form of efferent neurons) which are carried down the spinal cord and to your PNS (i.e. somatic nervous system). When the motor message reaches your foot, a neurotransmitter is released, causing the muscle to contract, therefore producing the appropriate movement to kick the ball.

Thanks
