Errors in the performance of repetitive or “boring” tasks—often attributed to a momentary lapse in concentration—can be serious in such activities as flying a passenger aircraft. Is there any method that would provide warning of such lapses—for example by monitoring brain activity? Researchers scanned the brains of volunteers performing a repetitive task. When the tasks were being performed correctly, the volunteers' brains showed activity in cognitive-processing regions. However, these regions became less active several seconds before some errors were made, and another brain region, region X, became active. The researchers concluded that the monitoring of region X could provide warning of an impending error.
Which of the following, if true, most supports the researchers' conclusion?
  • a)
    The cognitive effort required in performing a repetitive task diminishes significantly with increases in the number of repetitions of the task performance.
  • b)
    Once a mistake was made and detected, brain activity in regions associated with cognitive effort sometimes increased.
  • c)
    Other research found that whenever significant activity occurs in region X, it is generally with repetitive tasks, soon before an error occurs.
  • d)
    The diminution of brain activity in cognitive processing regions and the increase of activity in region X began at least 5 seconds before the errors occurred.
  • e)
    Reduced activity in brain regions associated with cognitive effort was accompanied by increased activity in regions that become active during sleep.
Correct answer is option 'C'. Can you explain this answer?
Most Upvoted Answer
Errors in the performance of repetitive or “boring” tasks&...
Let's analyze each answer choice and see which one aligns best with the researchers' conclusion.
(A) The cognitive effort required in performing a repetitive task diminishes significantly with increases in the number of repetitions of the task performance.
  • This statement is about the diminishing cognitive effort with increased repetitions of the task. It does not directly support the researchers' conclusion about monitoring brain activity to provide warning of lapses in concentration. Therefore, (A) is not the correct answer.
(B) Once a mistake was made and detected, brain activity in regions associated with cognitive effort sometimes increased.
  • This statement provides information about brain activity after a mistake is made and detected. It does not directly support the researchers' conclusion about monitoring brain activity to provide a warning before the error occurs. Thus, (B) is not the correct answer.
(C) Other research found that whenever significant activity occurs in region X, it is generally with repetitive tasks, soon before an error occurs.
  • This statement directly supports the researchers' conclusion by stating that significant activity in region X occurs specifically with repetitive tasks and shortly before an error occurs. This information aligns with the researchers' findings and strengthens their conclusion. Therefore, (C) is the correct answer.
(D) The diminution of brain activity in cognitive processing regions and the increase of activity in region X began at least 5 seconds before the errors occurred.
  • This statement provides a specific time frame (at least 5 seconds) when the changes in brain activity occur before errors. It supports the researchers' conclusion by emphasizing that these changes in brain activity precede errors. However, it does not provide additional information to support the idea of monitoring region X specifically. Therefore, (D) is not the correct answer.
(E) Reduced activity in brain regions associated with cognitive effort was accompanied by increased activity in regions that become active during sleep.
  • This statement introduces a different aspect related to brain activity during sleep. Although it provides interesting information about the brain, it does not directly support the researchers' conclusion regarding monitoring brain activity to provide warning of lapses in concentration during repetitive tasks. Hence, (E) is not the correct answer.
In summary, (C) is the correct answer because it directly supports the researchers' conclusion by stating that significant activity in region X is associated with repetitive tasks and occurs shortly before an error.
