Exam Thoughts & Review

[Hylton]

It was D

It was fixed interval/variable-interval

but wtf was q4 and q5 about developmental and adaptive plasticity? (diminishes with age, increases, constant?) wtf?

I dont understand why you and most other people say the answer is variable interval. I agree it could be, but couldnt it also be variable ratio? The question asked for a method in which the kid would keep his room the tidiest, and variable ratio is meant to be the most effective schedule of reinforcement so it is it right or wrong?

Btw did ppl put benzodiazepine for the GABA q and then give an example. such as valium.

said benzodiazepine can be given didn't say which

Yeah that question was strange, I put down both the definition/role of GABA, and how lower GABA could be treated by using benzodiazepines [although probably with wrong spelling!] which would stimulate the activity of the GABA, but didn't give an example for fear of making more spelling mistakes

For that first multi-choice,
hippocampus is involved with consolidating (forming) declarative memories.
Knitting,  riding a bike and throwing a ball are all procedural memories, therefore not declarative and so arent affected (thank you unit 3!) so surely its the other one, remembering names

for the snake multi-choice,
wasnt systematic densensitisation/graduated exposure since there was no build up in successive approximations of the snake.
it was just BANG, straight into being at the enclosure. so flooding?

i thought the worst multichoice was the one about the latent learning of rats (Tolman study). the second question on that, i think it was #10 (not sure), 'This study was dependent on:
a) the rats had 'insight'
b) the rats were reinforced
c) the rats were not reinforced
d) the rats became familiar with the maze of the first few trials

i said C since if they were reinforced then the rats wouldnt have shown their learning in all trials, and therefore they wouldnt have shown latent learning in that 12th trial. but the question didnt actually specify which rats it was talking about, or which trial either.
very average question..

i was really happy with it overall, much better extended response than unit 3 for me!

What was the question again? D: (On the exam)

[REBORN]

No, it was actually learning them as I have a spare copy of the exam with me right now which I got from the supervisor. Now if I can work out how to upload the entire thing once I've scanned it we can all go crazy over the exam.

Will be much appreciated

[watto_22]

and then for that other one,
critical period = experience dependant
sensitive period = experience expectant

so for the person learning english, that was an experience dependant behaviour, then learning Italian was experience expectant
i think..

[REBORN]

opposite.

Italian = dependent.

Thus D.

No, learning English was experience-expectant. Learning Italians was experience-dependant, so the answer was D.

I wrote in variable ratio for the most effective, too Hehe

How would variable ratio work in that situation though? I mean yeah you are right, but it just doesn't make sense in this case.

@watto_22, I put D down for #10, although it could work for C too I guess. The definition of latent learning is that it is a form of learning that involves no direct reinforcement, and remains hidden or unexpressed until it is needed. C meets the first part, D meets the second part. Well...

[REBORN]

It said week. This is interval

[LukeMcA]

I said variable ratio would be the most effective, because John wouldn't be able to predict the time of his reinforcement, thus more inclined to keep his room tidy.

I said ratio though, because I said Fixed Ratio for the first part. The only reason I said 'Fixed ratio' was because it stated he would be reinforced providing he cleaned his room at the end of the week (and he may not always do it). If it was fixed interval, he would receive reinforcement regardless if he cleaned his room (e.g. Reinforcement at the end of every week).

[LukeMcA]

I'm so over VCAA's ambiguous questions. Both responses should be rewarded with marks.

[REBORN]

No. Fixed interval works on the basis provided the correct response is made.
