Hi
avigutman - the screenshot below shows the sequence of events. I have marked it with
[1] through
[6]. Hypothesis : Amongst blind people, (4) is recieving information about
(1) NOT THROUGH
(3) Test - i was hoping for a test to check between the relationship between
(1) and
(3) or maybe
(1) and
(4) {
[1] and
[3] is the best IMO}
Those would be better experiments (do you concur ?)
So a test like :
Quote:
Test Group : blind people (With successful sleep wake cycles)
Goal of test : test the relationship between [1] and [3] amongst the target group
Experiment - checking if their visual cortex's respond to changes in light and darkness.
To me, this seems to go against the premise: "people who are
totally blind due to lesions in the visual cortex of the brain." I take that to mean that their visual cortex is unable to detect (1). Do you have a different understanding,

OR

Test Group : blind people (With successful sleep wake cycles)
Goal of test : test the relationship between [1] and [4] amongst the target group
Experiment - checking if their pineal gland responds to changes in light and darkness.
Sure, this would be great, but I suspect that the only way to check this (I'm not a scientist) is to check the melatonin levels (in other words, maybe we can only check (4) by evaluating (5).

Option (B) seems to be checking the relationship between (1) and (5), within the test group
But doing this, you leave big gaps
Just because (1) and (5) are seen among blind people,
- can i really say (3) does not play a part in sending information to (4) ? [which is the hypothesis]
Maybe, within the test group, [3] is getting information about [1] through the another organ (Say through touch or feel - it gets cooler when the lights dim, hence you can feel the change in lights)
Once [3] gets information about [1], then [3] is then sending the info to [4], amongst blind people
Again, my understanding is that [3] is completely disabled.

- can i really say (4) must be causing (5) -- I cant. Maybe among the blind, (4) does not cause (5) at all.
Many gaps if you ask me, testing the relation between [1] and [5]
So you're saying that even if we have the information that answer choice (B) offers us, we still wouldn't be able to PROVE the hypothesis. Okay, sure. But that wasn't the question. The question was: which of the five answer choices would be most useful for purposes of evaluating the argument.
