Many researchers believe that intelligence is related to neural efficiency. Which of the following does NOT provide support for this suggestion?
A)There are modest relations between speed of neural response and intelligence test scores.
B)High scorers on intelligence tests use less glucose when solving problems.
C)Brain plasticity may be related to crystallized intelligence.
D)Intelligence is related to speed of processing.
E)Glucose consumption increases in people who score high on intelligence tests.

Question

Quizplus · Accepted Answer

The statement that glucose consumption increases in people who score high on intelligence tests contradicts the idea of neural efficiency, which suggests that more intelligent individuals use their brain resources more efficiently, typically indicated by less, not more, energy consumption (e.g., glucose) during problem-solving.
