Can't remember which one it was but help will be appreciated
Research into the effects of ageing on memory has shown
A processing speed in STM is reduced due to increased efficiency of the nervous system.
B processing speed in LTM is reduced due to reduced efficiency of the nervous system.
C there is no difference in processing speed for different types of task.
D complex tasks such as manipulating various types of information is often more difficult
for elderly people.
Which schedule of reinforcement results in the slowest extinction of a learned behaviour?
A fixed ratio
B variable ratio
C variable interval
D fixed interval
Thanks
hey man
these actually seem to be difficult questions.
for the first one
i would lean towards answer D.
since , complex tasks using the brain would possibly be less efficent as with ageing , as the central nervous system slows down.
however im not 100% sure
would actually be good to get some other peoples imput.
question 2.
Im pretty sure its variable interval.
for e.g fishing
when you go fishing. ... your gonna keep fishing all day .. even though you know that it might not happen.
the response is quite resistant to extinction.
some 1 please correct me if im wrong on anything.
cheers.
i checked they are from tssm 2008. i got D for the first one but it is B. For the seccond one I got B but its C. Although for Q2 it was 50/50 to which way I would go
ok , well i was wrong with q1.
but was right with 2.
ok lemme try explain my theory on the answers a little more .
question1.
the slowing of the nervous system means that tasks cannot be performed as well.
however , usually memory loss in older people is the memory loss in episodic memories.
episodic memories are apart of long term memory.
the retrieval process is slowed down .. due to the declining nervous system
HOWEVER
i still would like some 1 to tell me why the answer cannot be D.... it seems logical to me?
as for question2.
its in the gravias textbook page 470
there is a graph which shows rates of learning and in turn , extinction rate.
the various interval is the slowest .. but it has the HIGHEST resistance to extinction
