Intelligence has been a controversial topic in the history of psychology and there still continues to be disagreement in the components that are responsible for the make-up of it (Cherry, 2018).  There are several theories of intelligence.  Major theories include the following:

General Intelligence (Charles Spearman) used factor analysis to examine mental aptitude.

Primary Mental Abilities (Louis Thurstone) focused on seven mental abilities.

Verbal comprehension
Reasoning
Perceptual speed
Numerical ability
Associative memory
Spatial visualization

Multiple Intelligences (Howard Gardner) instead of IQ test scores, (8) types of intelligences based on skills and abilities.

Visual-spatial intelligence
Verbal-linguistic intelligence
Bodily-kinesthetic intelligence
Logical-mathematical intelligence
Interpersonal intelligence
Musical intelligence
Intrapersonal intelligence
Naturalistic intelligence

Triarchic Theory of Intelligence (Robert Sternberg) Referred to “successful intelligence,” which involves three different factors.

Analytical/Componential intelligence: Your problem-solving abilities.
Creative/Experiential intelligence: Your capacity to deal with new situations using past experiences and current skills.
Practical/Contextual intelligence: Your ability to adapt to a changing environment.
