The book traces the origins of the idea of individual differences in general mental ability to 19th century researchers Herbert Spencer and Francis Galton. Charles Spearman is credited for inventing factor analysis in the early 20th century, which enabled statistical testing of the hypothesis that general mental ability is required in all mental efforts.
Spearman's two-factor theory proposes that intelligence has two components: general intelligence ("g") and specific ability ("s"). [7] To explain the differences in performance on different tasks, Spearman hypothesized that the "s" component was specific to a certain aspect of intelligence.
The subsequent formulation was that the magnitude of the black-white difference on tests of cognitive ability is entirely or mainly a function of the extent to which a test measures general mental ability, or g. [2] Spearman's hypothesis has been criticized on methodological and empirical grounds. It has also been used to support scientific racism.
The challenge point framework, created by Mark A. Guadagnoli and Timothy D. Lee (2004), provides a theoretical basis to conceptualize the effects of various practice conditions in motor learning. This framework relates practice variables to the skill level of the individual, task difficulty, and information theory concepts.
[1] [2] It was influenced by the theory of g factor. [1] [2] Vernon puts emphasis on the g factor in all the mental abilities. He extracted the g factor from an ability test, then found that those remaining content [clarification needed] could be divided into two separate parts. He named those two orthogonal group factors as verbal-educational ...
Human Cognitive Abilities is divided into three parts: an introductory background section, a section discussing the different domains of cognitive ability, and a section discussing more general issues related to the study of such abilities, such as the three-stratum theory. [2]

An experiment of the quadriceps femoris found that motor units are in fact recruited in an orderly manner according to the size principle. [12] The study looked at average motor unit size and firing rate in relationships with force productions of the quadriceps femoris by using a clinical electromyograph (EMG). [12]
