Spearman's concept of g refers to a general intelligence factor that underlies all cognitive abilities. Therefore, individuals who are good at one cognitive task are likely to be good at others. This helps to explain why people who are good at math (a cognitive task) are also likely to be good at reading (another cognitive task).
