IS THIS RIGHT? I THINK ITS WRONG?

[sillysmile]

how do you spell psychology again??
and doesn't the CR trigger the NS?
I'm so confused!!!

CS triggers the CR, after the NS has had several pairings with the UCS to become the CS... If that makes sense..

I don't know if you're being sarcastic or not haha :S

i think he was being facetious shilayli....

Hahaha I thought so. But I just thought I'd be on the safe side and still explain it.

Question 35
In Skinner’s original experiments, behaviour that had been conditioned by which type of schedule was found
to be the most difÞ cult to extinguish?
A. variable schedule
B. fixed schedule
C. continuous reinforcement schedule
D. punishment schedule

so this was vcaa 2005, I think if they were to ask an extinction question again, it would be similar.

yeah I was just being silly :O)

May i just point out.

The Iartv/cse 2008 psych exam has MANY wrong answers for the SA questions regarding research methods.

1. Random sample wasn't used .. random ALLOCATION was used.
2. q15 .. correct me if i am wrong .. but with no provided P value , it is impossible to "support a hypothesis" with just the "number of errors mean"
3. YOU CANNOT make conclusions . the results are not inferential , they are descriptive.

dodgy exam paper.
Id stay away from it.

Many 3rd party papers are very very bad, unreliable, except for neap

Agreed.
I doubt ( although vcaa are bitches) they would make us differentiate between variable ratio/interval.

I've mentioned this somewhere before, but I agree with spreadbury. There's no reinforcer in CC, and stimulus occurs before a response in OC.
And you can't interchange reinforcer with stimulus, they're two completely different things.

Matt, the table you refer to :

I got that info from gravias.
Its a table with operant and classical conditioning

its got

1. nature of response
2. timing of response
etc etc

I have it here in front of me now, and it says "In OC, the presentation of the reinforcer depends on the response occurring first", which, yes is what you and shilayli06 are saying. However, it continues to say "The response occurs in the presence of a stimulus"
So no, you cannot interchange stimulus and response.

Furthermore, I have asked my teacher and he said the response always occurs after the stimulus.

[sillysmile]

 
the antecedent is a stimulus,
but so is reinforcement/punishment
and in a way they both influence the response ,

but the stimulus that is being referred to is the reinforcement/punishment

[sillysmile]

for the purpose of unit 4 psych anyway.

[Spreadbury]

for whom it may concern; my psych teachers except reply:

The term antecedents in operant conditioning means "the events that precede or come before it" (page 467).
Skinner believed that all behaviour can be explained be the relationships between the behaviour, what occured before the behaviour (antecedents), and the consequences of the behaviour.

IN regards to the stimulus question, there are a few things that you can say to illustrate that you are correct.
firstly in both classical conditioning and operant condition there can be stimulus discrimiation. For example (as given by the text book), "a pigeon was trained to peck as a switch mounted on the wall of a Skinner Box. The switch was lit be a green light. When the pigon was presented with lights of varing colours, it generalised the original stimulus (pecking the switch lit by a green light), and pecks at the other coloured switches as well." (pg 483).
secondly both CL and OP have stimulus dicrimintation (pg 484).
So there must be a stimulus that elicits the reposnse (the lever, stimululates the leaver pushing) otherwise how can there be stimulus generaliasation or discrimination.

The definition in the book is correct.

I don't mind

Each to their own. My teacher taught me something different and I'm confident in her knowledge so that's what I'm going with.

Just out of curiosity, how would all of you answer the following questions if they came up:

1) In operant conditioning the stimulus/reinforcer comes ___________ the response, while in classical conditioning the stimulus comes __________ the response.

A) Before; before
B) Before; after
C) After; before
D) After; after

2) In operant conditioning the stimulus comes ___________ the response, while in classical conditioning the stimulus comes __________ the response.

A) Before; before
B) Before; after
C) After; before
D) After; after
