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 than is that of the general population.
Situation- Human subjects are asked to recognize a pattern and perform the task to complete the pattern.
But the
results were surprising.Why ? Because the ones who succeeded in doing the task of pattern recognition and completion had the lowest energy expenditure of neurons in brain.
Evaluation-We have to account for the surprising results of the experiment.
We have to provide a reason for the finding.Hence, we have to provide a strengthener option and also resolve the surprising finding.
We have to find the WHY?
POE-
(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.
This option applies to both performed well as well to those who did not perform well.(B) Those who performed best in the experiment experienced more satisfaction when working with abstract patterns than did those who performed less well.
Satisfaction? what? What has satisfaction got to do with the finding?We have nothing that would confirm that more satisfaction results in less energy consumption.(C) People who are better at abstract pattern recognition have more energy-efficient neural connections.
This information accounts for the finding.It gives additional information that the ones who do well on pattern recognition are blessed with efficient neural coonections.Efficient neural connections help save energy!
(D) The energy expenditure of the subjects brains increases when a design that completes the initially recognized pattern is determined.
We are interested in overall energy consumption.Also if this option were true than it would mean that the ones who are successful may have used more energy than the ones who could not recognize and complete the pattern.(E) The task of completing a given design is more capably performed by athletes, whose energy expenditure is lower when they are at rest than is that of the general population.
The issue at hand is why the energy used by the successful ones is less than the energy used by the ones not successful.The athletes may have efficient neural networks BUT we want to know WHY do they have efficient networks.Hope the above helps.
