Quick question,

If the exam asks us to identify the response that is activated by the sympathetic NS, do we say ' fight=flight' of 'fight-flight-freeze' ?



You would say fight-flight-freeze as that is what it's called in the study design:
if you are wondering this because of the 'freeze' response not being activated the parasympathetic nervous system (not the sympathetic ns), you would still add it in as the fight and flight are more dominant in the name"fight-flight-freeze" and it therefore all comes under the sympathetic ns (if that makes sense)

I'm sorry that wasn't the best explanation, let me know if you want me to explain it better!

I'm still a bit confused because isn't the Freeze response governed by the parasympathetic NS?

Like if the scenario said the response is activated by the sympathetic NS, wouldn't you say just the fight-flight response [since the freeze response is by the parasympathetic?]

Say fight-flight-freeze, the sympathetic NS is also involved in the freeze response

Yep^
The freeze response kinda involves both- I'm assuming they'll stay away from any questions about this because its very unclear and everyone has different opinions

Hi guys,
For conscious and unconscious responses (i.e. spinal reflex), what nervous systems are used?

I know that for conscious responses, the somatic NS detects the sensory, send it to the brain (via spinal cord) where it is processed and the motor message is initiated to enact voluntary skeletal muscle movement via the somatic nervous system.
I also know that we have responses such as pupil dilation is all controlled by the autonomic NS. However, I'm a bit confused on what nervous systems are used for a spinal reflex, e.g. flinching from a hot pan

Thanks

This is also controlled by the somatic NS. Although the spinal reflex is involuntary, it still occurs through the somatic NS, because it involves the use of the skeletal muscles of the body.

We can eliminate the autonomic NS being an option, as this regulates the functioning of visceral muscles (non-skeletal), organs and glands, and it does not control skeletal muscles such as arm muscles (this is the somatic NS's role).

It also does involve the CNS due to it being a SPINAL reflex (as the spinal cord is in the CNS).

Hope this is a thorough enough explanation!

Hey guys, I know what the reconstructive nature of memory is, but am just wondering if anyone can give me a good way of expressing it if a question asked for it,

A memory is never consolidated and transferred into LTM in it's exact form, it is instead encoded so that it can neurologically placed into LTM. As a result the contents of a memory is combined with other stored memories to form what is believed to be a more accurate or coherent memory. What other information it is stored with is based on an individuals personal beliefs, personalties, experiences etc. When the memory is retrieved, it may be retrieved with other pieces of information that didn't actually happen, but have now been incorporated into the memory. 

In the same way, by retrieving a memory each time, new pieces of information can be added to a memory that did not actually happen (like what happens with leading questions)

Basically if it comes up in a question I think it's important to mention the fact that memories are encoded and not stored in their exact replica form, so they are combined with other pieces of information to make a more coherent and accurate memory, which can therefore distort the memory

AND

by retrieving the memory, it is subject to further reconstruction as new pieces of information may be added to the memory.

Okay these 2 questions have been buzzing in my mind and I need them answered:

Do benzodiazepines INCREASE or IMITATE GAB function???

What branch of the autonomic NS governs the Freeze response?

Benzodiazepines mimic the role of GABA (they are GABA agonists), and make the GABA receptors on the post synaptic neuron more responsive to GABA, in order to calm anxiety.

What branch of the autonomic NS governs the Freeze response?

The parasympathetic nervous system dominates over the sympathetic nervous system (heart rate decreases and blood pressure drops)

Some questions:

1. Do we have know what the decisional balance is in the transtheoretical model of change?

2. What are the advantages and limitations of video monitoring and also sleep diaries in sleep labs?

3. What's a good example of a speed and accuracy cognition test to measure consciousness?

4. Can someone please just sum up reliability and validity- I cannot seem to understand it (also, how can I tell if an experiment is both reliable and valid?)

2. What are the advantages and limitations of video monitoring and also sleep diaries in sleep
Video Monitoring
Advantage
-People can sleep in their natural environment
Disadvantage
-Interpretation can be subjective and don't tell us what internally is happening to the person

Sleep Dairies
Advantage
-Tell us the internal components such as the thoughts of the participants

Disadvantage
-The description may not be accurate and truthful
-Key information may be left out
-Can the description be interpreted?

Jack of all trades, master of none.
Hence why i'm in all these different threads and boards.

Thanks!!
What would an advantage of video monitoring be if it was used in a sleep lab?

3. I'm not sure if this is what you're looking for, but you could measure response time to obstacles in a driving simulator (it's really specific but we did a prac on this at school so thats why I remember it). The speed aspect of it would be how quickly you react to the obstacle, and the accuracy would be if you react to the obstacle at all
4. reliability refers to whether the results of an experiment are dependable and can be repeated if the experiment was done again. Validity is if the procedure for the experiment measures what it is supposed to measure

For example, if you wanted to see if body temp dropped before you fell asleep but your thermometer wasn't working properly and you got an inaccurate reading, then your results wouldn't be valid, because your results don't actually indicate the real temperature. However, if you still got the same results every time you measured the temperature, your results would be reliable

Might be good to know if you are asked a question on the stages in the transtheoretical model, maybe? The decisional balance is just where individuals in the contemplation stage weigh up the pros and cons in changing their behaviour, and think about the possibility of changing their behaviour.
