Challenging Psych Questions

As the subject suggests, this is a thread for psych questions that are challenging (/ most of the state got wrong). Don't worry if you get these wrong - have a go and see if they can help you learn and refine your responses! :)

Please put your answers in spoilers so that others can also have a go without being influenced by your response :) 
Good luck & here's the first set:
Set 1
1. Alex swims competitively. The area of the brain that would store Alex's memory of how to swim would be:
a) Hippocampus
b) Amygdala
c) Cerebellum
d) Cerebral Cortex

2. Sally was sitting around a campfire when a spider crawled onto her foot. She swiftly wacked it away and felt her heart rate increase. Later, she was rearranging wood in the fire and involuntarily jerked her arm away. She then saw that she has a blister forming on her hand.

a) What division of the nervous system was responsible for her wacking the spider away, and what type of response did she display? (2 marks)

b) Explain Sally's response when she jerked her arm away from the fire. ( 3 marks)


3. Describe what an antagonist is ( 2 marks)     [ this wasn't  directly a question BUT VCAA assumed people knew this and very few people did]


4. This is a pretty big question, and when I did this exam I considered it one of the hardest questions in there - but it doesn't require any year 12 specific knowledge! I'm going to link you the exam and please go to question 5 c iii    ( most of the state didn't get full marks for c i either and you should be able to do that one too )

Haven't done psych before, so I am only very vauge for these questions, however I do think I know Question 1, so I will answer that:
question 1
a) hippocampus
Its a pretty sad effort, but oh well ;D

feedback on answer
The hippocampus is involved in consolidation (making the memory) of explicit memories (eg, facts you know, memories of events) and doesn't really act as a storage site.

Since 4 c iii is based on scientific reasoning rather than any particular psych knowledge you could have shot at that one, if you're interested :)

haven't learnt the areas of the brain, only the lobes and cortices so will skip q1
2a) somatic nervous system, sympathetic response
b) Sensory neurons in Sally's arm detected and responded to potentially damaging heat from the fire, then relayed the information to interneurons within the spinal cord, which then sent it to motor neurons that initiated a motor response to withdraw the arm.
3) haven't learnt yet, but is it something that hinders a postsynaptic neuron from firing?
4i) matched participants design, minimises participant variables (i was only taught human research methods so idk if the terms apply to animals)
iii) The P+S group performed worst out of all four groups, as displayed by a lower mood and more maze trials.The P-S, C+S, C-S groups, however, all performed similarly, indicating that the intake of caffeine, or the placebo, may mitigate the effect of stress on mood and memory. Dr Cunha was thus able to conclude that there exists a casual link between caffeine consumption and stress prevention.
idk what else to write

I'm just beginning 1/2 psych, so I'll have a crack at 5 c iii. No idea if I've done this right!
5 c iii.
The comparison of the results of the P+S and P-S show that stress affects the memory and ability of the mice to learn the maze. The comparison of the results of the C+S and C-S groups show that the effect of stress on memory is minimal as the results of each test are similar. The differing results of P+S and C+S shows that the effect of stress on mood and memory is affected by caffeine. As the results of both of the C groups were alike to the results of the P-S group, caffeine consumption appears to prevent the effect of stress on mood and memory as the caffeine inhibits adenosine (not too sure about that) thus avoiding the impairment of memory function.

Edit - now that I've done a bit more psych:
Questions 1 & 2
1. cerebellum
2a. The Autonomic Nervous System (Sympathetic Nervous System), but the Somatic Nervous System would actually carry out the action, Fight-Flight-Freeze Response
2b. Sally's response was a reflex arc, an involuntary action. The sensory receptors would detect the sensation of the fire and a message is sent to the spinal cord via interneurons to pull her hand away from the fire. The interneurons in the spinal cord send a message to motor neurons that control the arm to move the muscle so that she is able to jerk her hand away.

Thanks for doing this, miniturtle! :)

1) The cerebellum? Out of all these parts only learnt about the cerebellum and cerebral cortex, but remembered the cerebellum is associated with balance and fine motor movements, while the cerebral cortex also contains the motor cortex that is responsible for voluntary movements so I'm not sure

1. Not sure, haven't learned this yet

2. a) - The peripheral nervous system, more specifically, the somatic nervous system
- She displayed a motor response
b) In this scenario, Sally has displayed a spinal reflex. The sensory receptors on Sally's hand first detected the heat from the fire and sent this sensory information via sensory neorons, to the spinal cord (CNS). Here, inter neurons processed and relayed back motor information via motor neurons to the muscles in Sally's arm, causing the muscles to contract and jerk away from the fire.

3. haven't learnt

4. (5ci) - Matched participants design, an advantage of using this design is that it controls for and minimises the effect of participant differences on the experiment.

5ciii - Wow this is a very hard question. Not sure if this is a specific topic but i had a go anyway,
- Due to the fact that there were four groups of mice, Dr Cunha was more able to draw a conclusion on the effects caffeine has on preventing the effects of chronic stress. As shown by the research, mice that consumed a placebo and placed under stress drank less of the sweetened water (Indicating lower levels of mood), and took more trials to learn the maze (indicating lower memory performance) compared to the mice that were not placed under chronic stress. The however unlike the placebo groups, the mice that consumed caffeine performed similarly on the maze task and consumed a similar level of sweetened water, indicating that the effects of chronic stress may be prevented if caffeine is consumed. Dr Unhandy intensified these results and was able to compare how the four groups performed to determine...
I don't really know where i was going and how to answer this one

1. Haven't learnt it yet
2a) The Somatic Nervous System of the PNS is responsible for allowing Sally to wack the spider away. She displayed a physiological response as her Sympathetic Nervous System activated which enabled her heart rate to increase.
2b) Sally's response when she jerked her arm away from the fire is an example of a spinal reflex. Her sensory neurons detects the sensation of the heat, relaying afferent impulses towards her spinal cord. The interneurons within the spinal cord help connect and send a motor message which allows her to jerk her arm away without any involvement of the brain.
3) An antagonist is a substance that decreases the receptiveness of dendritic receptors to a particular neurotransmitter making it less likely to fire
I'll do question 4 later, I'm in class ;(

hey everyone, I've provided some feedback for all of the questions below. Overall you've done very well, especially considering that most of the state got these questions wrong when they were in their exams :)

Thank you to everyone who has contributed their thoughts thus far :)
general feedback
1. Cerebellum (it's a procedural memory)
2. Yep, the action itself was enabled by the somatic NS. There's a lot of different correct answers for the type of response - based on what VCAA has awarded as correct for a similar question any of the following would be accepted: voluntary response, conscious response, controlled response
3. An antagonist is basically the opposite of an agonist (if you do not understand both agonists and antagonists after covering benzodiazapines being GABA agonists (in the mental health topic) make sure you cover it on your own). An agonist mimics the action of another substance (eg when benzodiazapines binds to a receptor a similar response is initiated as if GABA had bound to the receptor); when an antagonist binds to a receptor it won't initiate the response and can block the receptor.
5ci. It is indeed matched participants and minimises participant variables is a correct answer. Note that you can use this terminology with animals (doesn't have to be humans).
5ciii.
"Due to the fact that there were four groups of mice, Dr Cunha was more able to draw a conclusion on the effects caffeine has on preventing the effects of chronic stress." -> this sentence implies that you can always draw conclusions if there are multiple groups, so I would not use it.

" As shown by the research, mice that consumed a placebo and placed under stress drank less of the sweetened water (Indicating lower levels of mood), and took more trials to learn the maze (indicating lower memory performance) compared to the mice that were not placed under chronic stress. The however unlike the placebo groups, the mice that consumed caffeine performed similarly on the maze task and consumed a similar level of sweetened water, indicating that the effects of chronic stress may be prevented if caffeine is consumed. "  Nothing you have said is wrong and the  ( ) are a nice touch, you've also accurately compared the results to draw a conclusion (effects of chronic stress may...). The problem is that this is not what the question is asking for. The question wants you to explain why the 4 groups were necessary to draw a conclusion and how this was done. Definitely an unusual question and your answer would be great for a more "normal" question.


"The comparison of the results of the P+S and P-S show that stress affects the memory and ability of the mice to learn the maze. The comparison of the results of the C+S and C-S groups show that the effect of stress on memory is minimal when caffeine is present as the results of each test are similar. The differing results of P+S and C+S shows that the effect of stress on mood and memory is affected by caffeine. " This is a good approach but it wouldn't get full marks. Comparison of the placebo groups and the caffeine groups is the way to go, but you there's more you should include. The P+S & P-S results do show that, and they also answer  "what does normal maze learning look like? what does normal sweetened water drinking look like?"). In general, if you are explaining the purpose of a control group consider that it provides a baseline.

"As the results of both of the C groups were alike to the results of the P-S group, caffeine consumption appears to prevent the effect of stress on mood and memory as the caffeine inhibits adenosine (not too sure about that) thus avoiding the impairment of memory function. "   We know this is a guess, and it's not in the study design to know the relationship between adenosine and caffeine - so don't state this as though it's not a guess. Rather than "as" consider "which suggests that" or similar wording.
