Explanation on a couple of prac exam questions

[matt123]

it's easiest to say that variable-ratio is as you can use the gambling example. i'm pretty sure that it's variable-interval as well, but my example of "fishing" doesn't really justify it being resistant to extinction

I think that the "gambling scenario" ( and this is just my personal thought) .. is both variable AND fixed interval.
... machines these days work on both time periods and number periods.

that's just what my teacher and I believe ... dont quote me on it.

But i would say ( since ive seen it in the book + on most exam papers) .... the most resistant to extinction is variable INTERVAL ..

Can anyone give a possible answer for VCAA short answer 2009 Q16? I can never get these

Answers just say 'In this question students needed to name one uncontrolled variable and then explain how this variable affected results.'

yep, an confounding variable could be the experimenter effect/bias: which occurs when the concious or unconscious expectations of the experimenter influence the behavioural responses of the participants (e.g. the experimenter treats the ppts who watch the literacy program every day, better than the ppts in the other group)

on the mc i am actually doing better than expected but it was weird. there was rm questions in the memory or learning section and a couple of questions asked for what sounded like a detailed response and only was worth 2 marks with 2 lines. I reckon TSSM are the best tbh

i just do as many mc as i know and write them in immediatly when reading time finishes. gives you an advantage by giving you more time to do SA

[sillysmile]

I usually concentrate on reading the short answer questions.

Honestly.
READ short answer questions ... and formulate answers to them.
then when time starts
do multi choices first
