Last Minute Questions

General adaptation syndrome (GAS) is a three-stage physiological stress response that occurs regardless of the stressor that is encountered.
Is this an acceptable definition?

For one mark, I would say yes For more than one mark, you probably have to include what the stages are and describe them. If it is for three ore four marks, probably give an example.

hey do you guys know which neuroimaging technologies are used to show changes in the brain related to learning and why? I can't seem to get my head around this!

Functional Magnetic Resonance Imaging (FMRI)
Single Photon Emission Computed Tomography (SPECT)
Positron Emission Tomography (PET)
These allow the changes in the brain to be observed that occur when and after learning takes place, which can be achieved by monitoring blood flow during learning. They also enable researchers to see the exact areas of the brain involved in learning.

ahhhh thankyou so much! greatly appreciated!!

Except I just realised it's "Single Photon Emission Computed Tomography", my bad...

sample vcaa exam q19 SA:
Dr Smith wanted to investigate the brain structures that change during the process of learning. To do this, she
recruited 15 of her daughter’s friends. Each participant attended two trials at the neuroimaging clinic at the
university at which Dr Smith worked.
Trial 1. The participants read words written in an unfamiliar language. They then read the same words which
had been mirror-reversed while scans of their brains were taken.
In this trial, the participants read the mirror-reversed words slowly and made numerous errors.
The scan indicated that the right parietal cortex was active as the participants were using spatial cognition to
mentally reverse the letters.
After the scanning, the participants practised the skill of reading mirror-reversed words for one week. A week
after the first trial, there was a second trial.
Trial 2. The same participants read a list of mirror-reversed English words.
In the second trial, the participants read the mirror-reversed words more quickly and accurately than in the first
trial.
Scans from the second trial revealed that the right parietal cortex was no longer used in the reading of the words.
Instead, there was activity in the left temporal cortex, the area of the brain which is responsible for interpretation
of language and reading
Question 19
What conclusion could be drawn about the differences in the scans between Trial 1 and Trial 2?
i need help with this question, what would the answer be? D:

What is the exact role of NMDA and glutamate in learning? I have a general idea but my textbook gives the definition rather clumsily.

[smcb]

Aren't the stages of Developmental plasticity

Proliferation
Migration
Circuit formation

?

[krith]

Glutamate stimulates the growth of dendritic spines and makes the postsynaptic neuron more receptive to future bursts of glutamate resulting in long lasting structural changes and is essentially is the main excitatory neurotransmitter in the brain (counterbalances GABA)
NMDA is a glutamate receptor which produces long-lasting changes to the synapse (LTP). Without NMDA, any message with glutamate cannot be received by the postsynaptic neuron

Hopefully this is right

Not 100% on this, but I've written that no conclusion can be made as there was no control condition in either trial to compare the differences in the scans

I forgot about NMDA. Hope it doesn't appear tomorrow...

omg i feel like theres so much i dont know D:
Question 36
Addictive disorder: gambling
a. Name and describe an evidence-based treatment often used by psychologists in the treatment of gambling.
do any of you guys know what 'evidence-based treatments' mean? i was thinking maybe dopamine antagonists or cbt but idk D:
