Makes sense but is the stimulation of the neural pathway responsible for fear due to them constantly thinking about it or actual exposure to the stimulus. Because wouldn't exposure to the stimulus help them to overcome it through desensitization?


Bascially, LTP is a PERPETUATING risk factor for a phobia, meaning that it maintains the onset of the specific phobia. It neurologically strengthens the associatoin between a phobic stimulus and a fear or anxiety response through its activity at the syapse. The more times a phobic stimulus is encountered, the more the fear response will be strengthened through long term potentiaion.

This usually results when a person encounters the specific situation in which they have a phobia, and it is not likely that they will overcome the phobia by themselves. For example a person who is scared of flying in planes will still most likely be scared whenever they take a flight, regardless if they have flown a lot in the past. The association is so strong between their phobia of planes and experieicing anxiety that synaptic transmission responsible for these neural pathway will be very efficient.

I hope this helped a little. It is a difficult concept to grasp initially.

if we're asked about why a child recovers from brain damage faster than an adult do we talk about developmental and adaptive plasticity as in past years? or just that children have higher levels of neural plasticity and this reduces throughout the lifespan??

As far as I'm aware, this is not a part of the current study design, and is therefore not examinable. However, to answer your question I'm pretty sure you would emphasise the role of adaptive plasticity in a child.

does synaptic pruning occur during LTD or is that only in developmental plasticity? what changes occur to the synapse during LTD?

I've just re-checked the study design and both ADAPTIVE and DEVELOPMENTAL plasiticty are not listed in either Unit 3 or 4. I've listed the dot-points below from this area.

Neural basis of learning and memory
• neural plasticity and changes to connections between neurons (including long-term potentiation and long-term
depression) as the fundamental mechanisms of memory formation that leads to learning
• the role of neurotransmitters and neurohormones in the neural basis of memory and learning (including the role of
glutamate in synaptic plasticity and the role of adrenaline in the consolidation of emotionally arousing experiences).

Hey guys,

What are some examples of speed and accuracy's task that measure an individuals state of consciousness apart from driving simulators.

Thanks!

For LTD just think the opposite of LTP. The neural connections weaken due to:
-less neurotransmitters being released
-less receptors
-less uptake channels
-pruning

i think i was told to assume that if a q says 'reinforcement' to assume it means positive reinforcement and 'punishment' as positive punishment. SO if we are asked the difference between 'reinforcement and negative punishment' for example, do we describe the difference between positive reinforcement and negative punishment, or the difference between positive/negative reinforcement and negative punishment?

do we need to know how to manage stress in terms of biopsychosocial framework (besides from exercise and maybe social support)?

I don't believe you do need to know it under a biospsychosocial framework because the different coping strategies (context-specific effectiveness, coping flexibility, exercise and approach and avoidance coping strategies)are not definite under a certain category.

question from 2016 exam:
Zahra is a first-time mother. When her baby boy was eight weeks old, Zahra’s mother, who lives overseas,
came to stay for six weeks to help care for her new grandson and to help Zahra adjust to her new role as
a parent. Zahra also started attending a group for new parents, run by a maternal and child health nurse
through her local council, where she meets once a week with a group of five other first-time parents.
Explain how one source of social support identified in the scenario could help alleviate Zahra’s stress
response associated with caring for a newborn.


I identified a source of social support - attending group for new parents and said that this would allow her to learn new info about caring for her baby and that it was an approach coping strategy. In the answer for a mark you had to say how this causes stress to reduce through changing appraisals of coping
I did not explicitly say that she would change her appraisal of coping but is saying that she used an approach coping strategy to deal with the stress sufficient for the marks?

thanks

I think that you wouldn't get full marks, because you didn't explain how it would alleviate her stress, and that's what the question is asking for

What is a good definition for the evolutionary theory of sleep?

And what are 2 (good, easy to understand) pieces of evidence?

Thanks!
