What aspect of intelligence is highlighted in Spearman's "g" factor?

Spearman's "g" factor emphasizes general cognitive ability, which refers to the overall mental capacity that influences performance across a variety of tasks and domains. This concept posits that individuals possess a single underlying intelligence that can affect their skills and abilities in multiple areas, such as reasoning, problem-solving, and learning.

The "g" factor arises from Spearman's observations that people's performance on different cognitive tasks is often positively correlated, meaning that those who excel in one cognitive area tend to perform well in others. This idea suggests that there is a common factor contributing to overall cognitive performance, contrasting with theories that might focus on specific skills or different types of intelligence.

In summary, considering Spearman’s framework, "g" provides a unifying perspective on intelligence, highlighting the role of general cognitive ability in various intellectual endeavors.
