An experiment was done in which human subjects recognize

Post Mon Nov 21, 2011 9:18 pm
An experiment was done in which human subjects recognize a pattern within a matrix of abstract designs and
then select another design that completes that pattern. The results of the experiment were surprising. The
lowest expenditure of energy in neurons in the brain was found in those subjects who performed most
successfully in the experiments.
Which of the following hypotheses best accounts for the findings of the experiment?
(A) The neurons of the brain react less when a subject is trying to recognize patterns than when the subject is
doing other kinds of reasoning.
(B) Those who performed best in the experiment experienced more satisfaction when working with abstract
patterns than did those who performed less well.
(C) People who are better at abstract pattern recognition have more energy-efficient neural connections.
(D) The energy expenditure of the subjects’ brains increases when a design that completes the initially
recognized pattern is determined.
(E) The task of completing a given design is more capably performed by athletes, whose energy expenditure
is lower when they are at rest.

OA C

Can anyone please explain what are we supposed to understand by energy-efficient neural connections ??? and how does that make C the hypothesis that we are looking for ?? How does C relate to such surprising findings ??

Thanks

the argument saying that the experiment ask applicants to recognize a matrix pattern of abstract design and they noticed that the more successful ppl are in recognizing the pattern, the less energy the brain consumed.. for finding a hypothesis for this we need to have all these wording in our hypothesis....
we have 'more successful to recognize the abstract design matrix pattern and also lees energy consumption'.. then it is reasonable to have energy efficiency and better pattern recognition in our hypothesis... choice C is correct answer choice

hope it helps

Some background knowledge about the neural connections (Totally out of interest). Neural connections keep changing through out the life. More we understand stuffs, less becomes the reaction time when we see the same thing next time. Thus, the connections break when we discard a knowledge and new connections are formed when we accept a knowledge.(Goes through out our life cycle)- I saw an episode on this somewhere.

On to question.
The argument says that The results of the experiment were surprising , because the expectation was that more successful a subject was in recognizing another design that completes that previous pattern, more energy would it take for the brain. However, as the People who are better at abstract pattern recognition have more energy-efficient neural connections, the brain is trained to recognize those patterns in most effective way, consuming less energy.
