Psych U4 Q's Thread!

It's C

this may sound like a stupid question but is cbt a form of psychotherapy? or is psychodynamic psychotherapy the only type of psychotherapy? =)

Well, the term psychotherapy is a broad term I think, so I'd say so. Here is what Wikipedia says: "Cognitive behavioral therapy (CBT) is a psychotherapeutic approach: a talking therapy. "

So yes, the cognitive component of CBT can be considered a psychotherapy I think

okay thanks. Mistakes in textbooks are really not helpful
:l

thanks. how do we operationalize an iv? someone suggested that if we had an extended response with research methods we should state an iv and dv and then operationalized iv's and dv's.

Does anyone know the schedules of reinforcement in order from most resistant to extinction to the least resistant? I've seen so many prac Qs on this but it isn't explicitly stated in the grivas textbook.
Would it be
1. variable interval (most)
2. variable ratio
3. fixed interval
4. fixed ratio ? (least)

pas0005, you just give as much detail about exactly how it will be manipulated/measured , for example instead of saying "exercise will make one fitter" you say what theyll be doing for exercise, for how long, and how their fitness will be assessed... just heaps of detail.

Isn't variable ratio the most?

that's why i'm asking, we were never told the order of least to most resistant and I don't know how to deduce what it would be for sure what would you say they are?

[pas0005]

oh, now i get it. thanks. can you draw conclusions or state the hypothesis was supported if the sample was a convenience sample?

hmm im not sure about your question

[harlequinphoenix]

yes i think so, as long as the results are valid/significant or whatever, but I think that means no generalisations can be made. I need to read up on all that haha.

We weren't taught them either, but from exams:

Variable ratio maintains a maximal rate of responding and hence most resistant to extinction
Continuous leads to fastest acquisition
Continuous is most easily extinguished
A fixed ratio schedule promotes the quickest response rate
Variable interval results in slowest acquisition of the behaviour.

NEAP NEAP NEAP !

I have a few MC questions from NEAP can someone please help me clarify

Which of the following describes the use of Benzodiazepine in treating phobic anxiety disorders?
A. It has an agonistic effect, thus stimulating activity at the site of the post synaptic neuron
B. It has an antagonistic effect, thus stimulating activity at the site of the post synaptic neuron.
C. It has an agonistic effect, thus inhibiting activity at the site of the post synaptic neuron.
D. It has an antagonistic effect, thus inhibiting activity at the site of the post synaptic neuron.

I think It's C, they reckon it's A.

Grivas pg 639:
"Benzodiazepines are GABA agonists"
"benzodiazepines have inhibitory effects on the post synaptic neurones throughout the brain"


In terms of acquisition and maintenance of a phobia,
A. it can be maintained through operant conditioning, but cannot be acquired through operant conditioning
B. it can be acquired through operant conditioning, but cannot be maintained through operant conditioning
C. phobias cannot be acquired or maintained through operant conditioning
D. they can both be acquired and maintained through both classical and operant conditioning

They reckon it's D. I know that a phobia can be acquired through operant and classical conditioning and maintained through operant conditioning but does anyone know if it can be maintained by classical conditioning?

Many thanks.

C, no answer for that MCQ

Many thanks.

benzos imitate and stimulate the activity of GABA at post-synaptic neurons, but as you said this has the effect of INHIBITING the actual action of the neuron. tiny bit ambiguous that question.
well the book doesn't say CC maintains phobias but i guess if you always saw spiders around and kept experiencing the reflexive, involuntary response of fear repeatedly the association would only strengthen and would be resistant to extinction. But yeah, explaining how CC maintains a phobia would be clutching at straws a bit as it's not really in the grivas textbook. :l

monkey - Do you have access to the short answers for the grivas book?
