Question

Quizplus · Accepted Answer

The tendency for separate abilities to correlate within individuals supports Spearman's theory of a general intelligence factor. This means that people who perform well in one area, such as verbal reasoning, are likely to also perform well in other areas such as spatial reasoning or mathematics. This suggests that there is a common factor tying together various abilities, which is consistent with Spearman's idea of general intelligence, or "g." The other options do not provide direct evidence for Spearman's theory of general intelligence.
