When might a median be a more valid statistic than a mean? - are both equally impacted by outliers?
-
Question 38, on psyched 2018 states; ‘Tyson has started drinking alcohol heavily to deal with the stress he is under’ and then asks what 4P factor his heavy drinking relates to – I assumed it was ‘precipitating’ as that would correlate directly to substance use however the answer guide says ‘perpetuating’ – is this because his drinking is a result of precipitating risk being stress – or as such are the factors in the table non binary? ‘Excessive alcohol consumption is an avoidance coping strategy that is likely to inhibit his recovery from the stressors that he is facing’

• Can implicit memories be stored in the cerebral cortex? – specifically the primary motor cortex? Or is it more correct to say that they are all consolidated and stored in the cerebellum? Are there exceptions to this?
-
What is the difference between content limitations as a psychological measure of consciousness in comparison to day dreaming? – is daydreaming a result of poor content limitations?
-
When might a median be a more valid statistic than a mean? - are both equally impacted by outliers?
Median is better to use when there is a limited amount of data, or when there are many outliers, whereas mean is better to use when scores in a set of data cluster closely around a central score and when there are no outliers.
Both are not equally impacted by outliers.
Most of the time, go for the mean. It is tested the most in psych and median is rarely used. Same with mode, being rarely used.

Alcohol use seems to be perpetuating in this circumstance as it is occurring after his stress. If it was occurring before, it may be considered as precipitating his stress. Similar to poor sleep, substance use can be precipitating or perpetuating based on the scenario.
• Can implicit memories be stored in the cerebral cortex? – specifically the primary motor cortex? Or is it more correct to say that they are all consolidated and stored in the cerebellum? Are there exceptions to this?
Implicit memories are not stored ANYWHERE in the cerebral cortex according to VCE psychology. Implicit procedural memories are stored in the neural pathways between the cerebellum and basal ganglia. For VCAA, just saying they are stored in the cerebellum should be enough. Classically conditioned motor reflexes are also stored here. Classical conditioning involving the conditioning of fear (i.e. Little Albert) is stored in the amygdala. The amygdala is responsible for the consolidation and storage of implicit emotional classically conditioned memories.
What is the difference between content limitations as a psychological measure of consciousness in comparison to day dreaming? – is daydreaming a result of poor content limitations?
Reduced content limitations are a characteristic of daydreaming, an ASC.
it shall be in my best interests that I avoid this thread forever or at least until examiners report comes out

How did everyone go?
I thought I was lowkey difficulty in terms of what the question really wanted from you. I was walking home and just thinking of all the possibilities of what I could have written but didn't. ):

Yeah. I noticed a few questions that seemed a bit ambiguous in terms of what I should write in my response too.
Try to to dwell on what you could have wrote though. It's done now and good job!

Hardest psych exam this study design by far. So many multi’s were scuffed. Anyone get n extra copy of the exam by any chance?

Thanks, (: good job too

What topics were tested mostly? Pretty good range?

Your teacher will probably have a copy so you can ask them. However sharing the exam on atar notes is a copyright infringement and is not allowed. As such the exam can't be posted here if anyone does have a copy.
No, ): idk but maybe you can access it online now because it's finished?
It will take many months until it gets published unfortunately
-

The ten mark question was mainly on Atkinson's model for memory, there was one whole question for learning,
Little stuff on Parkinson's and consciousness from what I can remember. A little bit on stress too
-

- median is the most suitable when the data set is skewed (+ve or -ve). Conversely, mean is valid when the data is approximately symmetrical.
- median is not very affected by the presence of outlier(s), while mean is very much affected.
Good Luck

Is it just me or did anyone else find MC questions bit more difficult than usual?
Usually, I can finish MC in 10 -15 min but today it nearly took me 30 mins.
How did u guys go with the 10 marker? I personally found the theory side of it alright, but linking back to the scenario was sorta difficult for me.

MC was 100% harder than previous years, they took my 15 mins longer than it usually does. I dropped 7 marks in multi’s this year , but to be fair everyone would’ve found it hard so it’s okay

Yeah same, the mcs took a while :/ I forgot to insert Loftus into the ten mark question which made me very sad. But yeah. Good job (:

Is informed consent required for both the 16 yr old participant and their parent or just the parent??
I did both, because surely they still need to consent as well, even if they are u18

It’s both

Why tf was video monitoring better than and emg for the 8 yr old sleepwalker. Also why was observational study better than experiment for astronauts
-

I mean like, EMG records the electrical activities of the muscles, whereas video monitoring records external physiological movements, and because the mother 'suspected' her son was sleepwalking than video monitoring would be a more practical approach.
also
I wrote about how when you use an EMG you have to place 'pads' on a person, this could prevent Jack from actually walking. And I also talked about artificiality, and how video monitoring limits reduces an artificial enviroment.
idk if that's correct.
-
It’s both
i always thought that you get informed consent from the parent/guardian but you explain the procedures to the 16 year old.

Wow that's a really good interpretation. I said how it will allow the dr to observe the sleepwalking actual happen in a natural environment.

This I had to think really hard because it wasn't something I knew well. I just wrote how it will allow the experimenters to observe and record natural astronaut behaviour. (: the whole exam was difficult lol
-

Yeah the actual signing would be from parent/guardian but you’d still have to explain the nature risk and rights to the adolescent and the parent/Guardia
-

I said that since he was sleep walking, a EMG would resemble electrical muscle movement similar to normal waking consciousness. Therefore, to distinguish, video monitoring in which you can see the behaviour for what it is would be better.
For the observational study, it is better than an experiment because you need to observe natural behaviour. Also, you cannot replicate space in a contrived environment.
-
Video monitoring will actually confirm that the sleepwalker was in fact sleep walking via visual recordings. Whereas, the EMG may be unclear as it may display high electrical activity that could indicate that the individual could be sleep walking; however, they may have instead just awoken and so voluntary got up and went to the fridge e.g. which would display high electrical activity.

Anyone think will Psych get scaled up this year i hope so or stays the same
-
Does anyone remember what they wrote for the classical conditioning/operant conditioning question on the dogs?
-
what did yall write for the question where it's like, ' why did the trainer use a negative stimulus in the first stage? '
Anyone think will Psych get scaled up this year i hope so or stays the same
I hope so too, but idk . . . seems unlikely
-

i went on the lines of 1. Through the eyes of operant conditioning e.g. i think i said something like it acts as a punisher which will decrease the liklihood of the dog approaching the snake 2. Through the eyes of classical conditioning e.g. i think i said something like it will cause the dog to associate snakes with pain from the shock and so will avoid them

whew
that's similar to what I wrote, I talked about aspects of how the reaction is precipitated through cc and perpetuated via positive reinforcement (operant conditioning)
thnx

Oh wow. Damn I honestly didn't even think about it that way, but that makes sense 100%. I think I just wrote something completely random. Was that question out of 2 or 4 marks do you remember? It seemed really ambiguous to me, especially since we had never covered what a 'negative stimulus' was in class before.
-
Also how much did you guys link the ER back to the scenario? In all honesty I was so nervous that I worked with one piece of information being the student hearing 'your locker number is 36' for the entire question without linking anything else in. Will it be penalised a lot?
-
For the negative stimulus question, I didn’t explicitly state operant and classical conditioning but I did those two concepts, I said
1) they’ll associate the negative stimulus ( shock ) with snakes and learn to avoid snakes ( conditioned stimulus )
2) they’ll be negatively reinforced to avoid the negative stimulus through avoidance behaviour as the aversive stimulus is being taken away to reinforce the avoidance behaviour ( I wasn’t sure if I should use punishment )
For the ten marker, I tried to talk about the scenario in my responses but I used generic ones like the teacher’ voice saying hello or what the teacher was wearing or the school classroom setting, etc

I did something similar :( but instead i talked about the student listening to the teacher in class and how it progresses through their memory..
Then i heard people discussed loftus' research and I then realised how screwed I was haha..
-
I rushed it so forgot to use examples from the situation for heaps, so my response was really generic :( (wont get above 7 i think then), but i talked about role of adrenaline in emotionally arousing experiences (and so the amygdala/hippocampus/episodic memory etc.), LTP, context dependent cues (ran out of time to do state), elaborative rehearsal (not sure about this) and memory reconstruction in general as well as Loftus' proposal of memory reconstruction.

Any chance anyone has the multiple choice solutions??? I just wanna see how bad I did because so far it’s not looking good :(
-

History would suggest probably not, but who knows? If you can avoid it, it's probably not worth thinking about too much. :)
-

This year I haven't looked at the exam and thus been unable to share suggested solutions. It's very common in and after exams to second guess yourself. Since you can't do anything about it now anyway, I suggest you focus on avoidance coping strategies like focusing on any other exams and trying not to dwell on it
Good luck to everyone

Yo this is kinda off topic but if you did Psyc last year but you are completing VCE and receiving your ATAR this year, is your psyc score from last year scaled based on last years scaling or this years scaling ... it's last years right?
I know some people that have been going around saying that us psyc accelerators last year might be lucky cos our scores might get scaled up because of how tough this years exam was - lmfao i hope this is true but i dont think so

You are scaled the same as the cohort you complete the subject in - not based on the year you graduate

Thanks for clarifying :D
Wouldn't have thought it would make any sense the other way

Will you have the chance to see the exam and make solutions eventually? Or do you know if anyone else will?
Thanks
