rehearsal is the most the most sensity measure of retention? what does this mean?

[Camo]

Are both the Thamalus and the Reticular Activating System involve in controlling sleep and wakefulness ? and does both control what information needs most attention ?

The RAS is a network of neurons extending in many directions to different parts of the brain and the spinal cord. The RAS functions are alertness, arousal and selective attention. The thalamus is a small strucutre on the top of the brain stem that filters and relays incoming sensory information other than smell to relevant cortical areas. The thalamus plays a role in filtering sensory information for attention, regulates arousal through a connection with the RAS.

So the Thamalus closes pathways while we sleep to prevent sensory information hitting the brain and both play roles in attention with the Thamalus filtering sensory information and the RAS regulating arousal, alertness and selective attention.

I'm guessing you meant rehearsal is the most sensitive measure of retention? Sensitivity refers to the amount of effort needed to access a memory, with the most sensitive information being the most easily detected. With rehearsal there are two kinds, elaborative and maintainence. I kind of need more information to answer, sorry.

For the eye question, B is correct isnt it?
information on the left visual field gets sent to the right half of each eye which then goes to the right occipital lobe, it think.

sensitivity of retention involves; how accurately a method is able to illustrate information has actually been stored in long term memory.
Recall is the least sensitive method; (free;cued;serial) basically retrieval without/or with the presence of very little cues
Recognition is more sensitive than recall; (identifying previously learnt stimuli among other stimuli)
Relearning is the most sensitive as it is assumed that if learning is quicker the second time around, some information has been 'saved' from the first learning experience; as calculated statistically with the savings score.
that's why it's the most sensitive; we can figuratively give a number to how much information has been saved in LTM.
Savings score = original time taken to learn - second time taken to learn / original time taken to learn X 100.

It should be A. B is wrong. The right half of each eye will cross over to the left occipital lobe, while the left half of each eye cross over to the right occipital lobe.

The type of memory most likely to remain reliable in a healthy but very elderly person is _________.

I thought it was procedural, but the solutions paper stated that it was "semantic". Can someone explain why? =/

At the Access Education lecture we were told that memory declines with by epsiodic then semantic then procedural, so I'm not sure.

Hey guys, you know for NWC and ASC... how you have the differences, i.e. content limtations, time orientations, perception, levels of awareness, emotional awareness etc...

Which ones are PSYCHOLOGICAL FACTORS and which ones are PHYSIOLOGICAL FACTORS?
We got an extended response question that asked us to clearly explain the differences in NWC and ASC in terms of these factors.

Help ?

[Russ]

Simplistically, if it involves a physical element, it's physiological (increased breathing etc.). If not, psychological.

[Zafaraaaa]

Content limtations, time orientation, perceptual awareness, emotional awareness- generally psychological factors
Increased GSR, Heart rate, breathing - physiological factors

Thank youu

Hold up. I just spent 20 minutes revising Sperry and Gazzaniga's research into split-brain procedures and from what I understand 'B' is the correct anwser. Why?

The left visual field is received by the right half of each eye. In turn this is processed in the RIGHT occipital lobe. We already know via hemispheric specialisation that the RIGHT hemisphere deals with sensory processing and motor control from/for the LEFT side of the body and vice versa.

At least I believe that's what the textbook is telling me. Anyone else?

[REBORN]

Indeed.

Right hemisphere = Left vis field = Right half of each eye

[monkeywantsabanana]

Hey guys (ssNake in particular)

I asked you a question the other day about the processing I'll ask it again.

INSIGHT 2009:
An image that is in the right visual field will be processed in:
A) the left occipital lobe
B) the right occipital lobe
C) both occipital lobes
D) the right occipital lobe first then the left occipital lobe

I reckon it's D. The answers reckon it's A and you explained to me that D is wrong :-S


I assume this is the same question...

VCAA 2007:
Visual information received by the right eye is processed in the

A. parietal lobe of the left hemisphere only.
B. occipital lobe of the left hemisphere only.
C. parietal lobe of right and left hemispheres.
D. occipital lobe of right and left hemispheres.

The answer is D so it's BOTH not just one hemisphere...

Can anyone please give me a plausible explanation?
