^^^


from my understanding

a conclusion is a two step procedure involving the acceptance or rejection of a hypothesis (which requires careful consideration of any extraneous variables). If no confounding variables exist than the results also if statistically significant can be applied to a wider population (generalization)

I might just add to that:-

In order to make a conclusion, you have to ensure the inferential statistics showed the results were significant, and you must take into consideration confounding variables. If you have any confounding variables - you can't conclude anything about whether the results are supported or not, as it impossible to know whether the effects of the DV were due to the IV or another factor. Similarly, if your results aren't statistically significant, no conclusions can be made.

When making a generalisation, you should take into account whether the sample is representative of the target population (look at whether random or convenience sampling has been used, whether only females or only males were used, etc.)

um yeah... lol it was about human development and "contact comfort" and he also isolated the monkeys looking at depression and loneliness...some fcked up stuff... and he saw that it always clung to cloth wired mother.. and when they were isolated they were all psychotic and stuff... real cruel stuff that wouldn't be approved by an ethics commitee nowadays..

Nope, it's a different Harry Harlow experiment with rhesus monkeys to what 3/4 VCE Psychology looks at.
In VCE they look at an experiment on learning set (or 'learning how to learn') - which is a transfer in the skills obtained from one learning scenario to another, similar learning scenario to ultimately improve or hinder the learning ability. There's not a huge amount of information out there about it.

The one you're talking about I'm pretty sure is part of the unit 1 psychology course though. And yes, it was terribly cruel :(

acquisition, shaping, extinction, spontaneous recovery, stimulus generlisation and distinction? of course!!! don't leave anything out of the course. i've seen questions on these before, including comparing the two, know them very well and how they differ from classical conditioning.

What do you mean you haven't seen a operant conditioning question yet?

Remember, no question (that's worth a high amount of marks) is ever going to ask you directly, what is operant conditioning? Or what is the processes of operant conditioning? More than likely, you'll get questions that may give a scenario, or how would you apply operant conditioning, and you will have to be familiar with the terminology to be able to answer the question effectively.

i think this may have been raised before, but can someone clearly identify and explain which schedules of reinforcement are the fastest to acquire and the slowest to extinguish?

i found out through the vcaa papers that
'continuous reinforcement, or fixed ratio (if continuous isn't there) are the quickest to acquire.
and the most resistant to extinction is variable ratio

in 2007 paper:
Marnie a nurse, gives Jimmy (8 yr old boy) an injection which is very painful. Now he screams when he is approached by a nurse.
I said:
UCS - Injection
UCR - Pain from injection

But, suggested answers are
UCS - Pain from needle
UCR - Fear of pain

In the scenario it does not say he is afraid of the pain, it just said it was painful, wouldn't the stimulus then be the needle which causes the pain???


edit; also, isn't informed consent only signed by parents if under 16? this is what my teacher told me, but in the VCAA paper it says under 18.


thanks.

Informed consent (for the purposes of research) is signed by parents for under 18s. It's different from medical or clinical situations, which is slightly more complex.

As for the question on the 2007 paper, I assume that you're meant to interpret the screaming as a fear response, hence the CR is the fear of getting an injection. Thus the assumption being is that the UCR would also be a fear response from getting injections.

Oh i see thanks, i'll put down under 18 in my notes than..Hmm, i think i get it. So basically i have to relate the CR to the UCR even though it doesn't really say what the UCR is, i just have to assume? Hopefully they won't give such a question, as i've never gotten any of the other scenarios like this wrong. ><

I don't think pain on its own can be a UCR. Don't worry though, I got this wrong as well. It's a very confusing one.

Is insightful learning grasping the rule required the solve the problem and knowing that you can solve the problem with that rule before you've actually applied it? Have I missed anything out?

Insightful learning isn't on the study design anymore - they shouldn't really be able to examine it.

And no - I think you just described learning set. Insight learning is when a species 'all of a sudden' realises how to solve a problem (like an epiphany). It's described as being an 'AHA!' moment. I wouldn't worry about it too much, though.
