A Thread For Questions

[Glockmeister]

from IARTV 2008

Q40) Jodie was grounded for being rude to her parents. This could be considered response cost because

A. Jodie was in her room and could no longer hear her parents nagging
B. Jodie was being prevented from going out with her friends.
C. Jodie was being physically punished for her rudeness.
D. Jodie experienced positive reinforcement.

Correct answer is B

Q41) In the scenario above, which one of the following, if any, represents negative reinforcement?

A. Jodie was in her room and could no longer hear her parents nagging
B. Jodie was being prevented from going out with her friends.
C. Jodie was being physically punished for her rudeness.
D. None of the above represents negative reinforment.

Correct answer is A and I chose D but i don't understand how A represents NR..

could someone kindly explain please? ty

This might be a little too late but...

40) Response Cost is sorta like a negative punishment, punishment from removing a positive stimulus, in this example , going out with friends. Don't worry too much about this, since I don't think response cost terminology is actually in the study design.

41) Negative Reinforcement is the removal of a stimulus to increase the probability of a behaviour happening. In this case, her parents nagging could be considered the negative stimulus, upon removal, it would increase the probability of a behaviour happening...

(it's not a well written question, I agree)

Good luck for tomorrow.

It's not too late =) Thanks for that Glockmeister, I think I get it now.

hahaha. as if your doing work for it now! i'm taking it easy this morning.

gooodluck all

This thread still works right? =)

I read that the frontal lobe is 'the end point of all sensory information and involved in logical thinking', and then for the left hemisphere 'involved in logical reasoning'. Does this mean logical thinking/reasoning is involved in the Left hemisphere and the Frontal lobe?

yes, i would think so, as the frontal lobe is responsible for all higher mental function and thinking including personality, so it would make sense that it would be responsible for logic, where it is predominately a left-frontal lobe function.

The way the VCE study design may teach it, may seem to imply that...

But in reality, it's a little more complex than that. Again, don't take the lateralisation of brain function (aside from isolated cases, e.g language and LH controls right hand of body and vice versa) as an absolute. You can not cut off the right frontal lobe and expect to still be able to logically think.

thanks for the help guys, one more question that's been bugging me.

The primary auditory cortex processes verbal info in the left hemisphere and non-verbal in the right hemisphere. Does this mean it's not contralateral?
As in sounds heard from the left ear are not processed in the right hemisphere and vice versa, it depends on whether it's verbal or not instead

Sac's on Friday, so want to weed out the uncertainties =)

I don't believe this is actually the case. When they talk about the non-verbal information, there's no sound and so, the PAC isn't truly involved (unless I'm misunderstanding you). Instead, it relies more on the visual pathways.

i still dont completely understand the association areas.. so exactly how many association areas are there? or are association areas every other part of the brain not including  sensory and motor areas (visual, auditory, etc..)
and afferent neurons send information to the central n.s while efferent neurons recieve information from the central n.s
could i correctly refer to brocas area as being responsible for the production of clear fluent speech, or is articulate speech a better description?
and if i was asked what the primary somatosensory cortex was resposible for, could a correct answer be; the primary somatosensory cortex is responsible for recieving bodily sensory information?
or should i include more detail..
thanks in advance

theres lots of association cortices... this is from a notebook from last yr..

premotor association cortex, pariteal association cortex, temporal association cortex, prefrontal association cortex...and apparently thye carry out higher level processing or functions (eg. personality traits, language, memory, consciousness)

and yep ur right about the afferent and efferents neurons

somatosensory cortex receives somatic inputs from the body in an ordered way... and also there are different 'sizes' of neurons devoted to more important functions in the body ie. body parts that are functionally more important occupy mmore of the cortical map area.

if a  question asks for two relatively non-invasive technique that shows function of an intact brain
would PET and fMRI be considered alright?

[TrueLight]

aren't those the only two that show function?

pet and fmri show function of an intact brain, but pet is considered to be a mildly invasive technique.. i think an EEG(electroencephalograph) would be a better answer than a pet scan (pet scans involve an injection of radioactive glucose)

Agree with that.
