PFIT Theory

Stands for Parieto-Frontal Integration Theory, which suggests that intelligence involves the integration of information between parietal and frontal brain regions.

Parietal Lobe

The area in each cerebral hemisphere that lies between the frontal and occipital lobes; includes tissue crucial for receiving information from the skin senses.

Frontal Lobe

The part of the brain located at the front of each cerebral hemisphere, responsible for voluntary movement, expressive language, and managing higher level executive functions.

Temporal Lobe

The areas in each cerebral hemisphere lying below the temples; includes tissue crucial for hearing and many aspects of language use.
