Question

Although it is a complicated relationship, brain volume (or "size," as measured by MRI) does correlate with intelligence (as measured by performance on intellectual tasks). What is the typical range of those correlations?

Answer 1

.30 to .40

Step-by-step explanation:

In simple words, The average brain size of healthy people is weakly associated with intellect, with a correlation rating of 0.3 to 0.4 out of a possible 1.0. In other terms, brain volume stands about 9 to 16 per cent for human intelligence variation altogether.

The capacity of people to consider innovative concepts, respond to changing situations, benefit from experience, thought abstractly, prepare and purpose vary. Via a variety of loosely linked principles such as cognitive ability and fluid or otherwise crystalline intelligence psychologists have attempted to explore these variations in intellectual capacity.
