Gq - Quantitative intelligence Definition

Definition of Quantitative Intelligence (Gq)

Quantitative intelligence is made up of other factors – particularly crystallized intelligence (Gc), fluid intelligence (Gf ) and short term / working memory (Gsm) as shown in the figure above. It is not understood as an independenent factor of general intelligence in itself. It has been defined as follows:

The breadth and depth of a person’s quantitative or numerical knowledge. Gq is largely acquired through the investment of other abilities primarily during formal educational experiences. Gq represents an individual’s store of acquired mathematical knowledge.
