Final answer:
Fluid Reasoning Index (FRI) is a measure of an individual's ability to solve problems, reason abstractly, and think flexibly.
Step-by-step explanation:
Fluid Reasoning Index (FRI) is a measure of an individual's ability to solve problems, reason abstractly, and think flexibly. It is one of the primary capacities assessed in cognitive assessments, such as IQ tests or neuropsychological evaluations.
Fluid reasoning involves using logic and analytical reasoning to solve problems that do not rely on prior knowledge or experience. It is considered a fundamental component of intelligence and is closely related to problem-solving and critical thinking skills.
An example of a task that assesses fluid reasoning is the Raven's Progressive Matrices, where individuals must identify the missing pattern or sequence in a series of abstract designs. The FRI score provides information about an individual's cognitive abilities and can be used to diagnose learning disabilities, intellectual disabilities, or giftedness.
