Fluid ability refers to one of two (2) higher Order factors of intelligence conceived by Cattell. Fluid ability refers to a person's genetically based intellectual capacity.

Fluid ability

Fluid functions refer to functions which believed to be culture -free and independent of learning. Problem solving and abstract reasoning are considered Fluid functions.

Fluid intelligence is defined as novel reasoning and the efficiency of solving new problems or responding to abstract ideas. It is defined also as the ability to perceive relationships and solve relational problems of the type that are not taught and are relatively free of cultural influences. Moreover, Fluid intelligence refer to abilities that make a person a flexible and adaptive thinker, that allow him/her to draw inferences, and that allow him/her to understand the relations among concepts independent of acquired knowledge and experience.

Fluorescent in situ hybridization (FISH) refers to a laboratory technique in which a DNA probe is labelled with a fluorescent dye to detect chromosomal abnormalities.

Flynn effect refers to the systematic increase or a rapid rise in IQ scores (about 3 points per decade) observed over the 20th century in several Western countries.

fMRI (Functional Magnetic Resonance Imaging) is a neuroimaging technique that is used to measure brain activity.

- fMRI (Functional magnetic resonance imaging) : fMRI or Functional magnetic resonance imaging is the modified version of MRI that measures energies released by hemoglobin molecules in an MRI scan and then determines the brain areas receiving the greatest supply of blood and oxygen; an imaging technique that uses MRI equipment to examine blood flow in a noninvasive, nonradioactive manner. fMRI, moreover, is a method of studying brain activity by using magnetic fields to track blood flow in the brain; non-invasive method of discovering which areas of the brain are active as a subject performs a task by measuring blood flow as an indicator of neuronal activity.
