Your general intelligence (called ‘g‘ or the ‘g Factor’) has been defined by 52 experts in the field as:

…a very general mental capability that, among other things, involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly and learn from experience.

An excellent collection of definitions of general intelligence and IQ is found in the paper A Collection Of Definitions Of Intelligence.

The IQ scholar Kevin McGrew has argued that intelligence has three basic dimensions – knowledge base, thinking skills & cognitive efficiency – made up of 5 broad abilities or factors. Click for the definitions of the different factors of IQ below.

knowledge base 

Gc: Crystallized intelligence – (Comprehension-knowledge) general knowledge, verbal ability.

thinking skills 

Gf: Fluid intelligence– reasoning and novel problem solving ability.

Gv: Visual intelligence – the ability to manipulate mental visual images to solve problems.

.

cognitive efficiency 

Gs: Processing speed – the speed / efficiency at which basic cognitive processes are executed.

Gwm: Working memory capacity – a short-term, constantly updated memory store for ‘online’ information processing – your ‘mental workspace’.
