Psych U4 Q's Thread!

[hotdog169]

what are the biological contributing factors that could contribute to a specific phobia referring to GABA and stress responces?

[mount franklin]

i wanted to know the same thing, good question hotdog169, wat are the biological contributing factors?

[Camo]

what threat information does the movie jaw transmit?

That water is dangerous, and sharks are present at beachs I would assume.

Someone's GABA system may be problematic, and may cause increased levels of anxiety.
Stress responses are fight-flight.

Can someone explain the function of re-appraisal under the model of stress/coping?

[REBORN]

A re-evaluation of a stressor in relation to coping resources.

Thus it occurs when there has been a [change] in the situation.

Eg: if you lose your job and then win 200 000 on Deal or No Deal....lack of money is no longer going to be a stressor.

Lol ^
Can anyone please accurately explain the mechanism of the GROWTH of more synapses? I understand Long-term potentiation (strengthening) but not exactly how MORE synapses are formed... I understand glutamate is involved but not exactly anything about the dendrites etc

[Russ]

The answer to that is biology not psychology (although it's a subset anyway) so this may not be relevant or necessary for you to know (it's also based on my understanding and since I never liked neuro much, it may not be accurate)

You're right about glutamate. Glutamate binds its receptor, which is known as NMDAR, and is the trigger for new synapse formation. There are a bunch of changes within the cell in response to this trigger. You're also right about dendrites being involved. In response to the glutamate trigger, they will rearrange their cytoskeleton to form new synapses with other neuron axons. This basically involves a restructuring to form new projections, neurotransmitter storage etc. that can form a new synapse.

Since glutamate is the key neurotransmitter between neurons, the more you use particular neural pathways, the more synapse formation you get.

NMDA for Psych=P ..is the R like a variant group?

[Russ]

R is the standard lazy way to write receptor

[buzzwith]

Results cannot be generalised if the sampling procedure eg convenience sampling is used, even though the results are statistically sgnificant.
Right?

[Russ]

No, it's not properly representative (that said the conclusions you draw from it will usually hold for the larger population)

[REBORN]

In other words - yes you're right; you cannot generalise with convenience sampling.

Does anyone know the weighting of the schizophrenia questions? Will it be a few marks like the practice exam on the VCAA website?
