Fluid intelligence

Fluid intelligence tends to peak early in life, whereas crystallized intelligence grows through adulthood, and into old age. Discover more key differences.

Fluid Intelligence refers to your ability to reason and solve new problems. This type of intelligence tends to be readily applicable to many types of problems. On the other hand, crystallized intelligence represents your ability to solve problems based on your knowledge and skills.

Explore the distinctions between fluid intelligence’s adaptability and crystallized intelligence’s knowledge-based application.

Fluid intelligence is the ability to solve unfamiliar problems using logical reasoning. It requires the effortful control of attention to understand what the problem is and to work toward a logical…

The relationship of human brain structure to cognitive function is complex, and how this relationship differs between childhood and adulthood is poorly understood. One strong hypothesis suggests the cognitive function of Fluid Intelligence (Gf) is dependent on prefrontal cortex and parietal cortex. In this work, we developed a novel graph convolutional neural networks (gCNNs) for the analysis of localized anatomic shape and prediction of Gf. Morphologic information of the cortical ribbons…

Fluid vs. crystallized intelligence

In her new book, cognitive neuroscientist Tali Sharot gets to grips with what our brains reveal about how we are influenced by others

Fluid intelligence refers to the ability to reason and solve novel problems, independent of any knowledge from the past. It involves the capacity to identify patterns, solve puzzles, and use abstract reasoning. On the other hand, crystallized intelligence refers to the ability to use knowledge, facts, and experience that one has accumulated over time. It includes vocabulary, general world knowledge, and the application of learned information.

Fluid Reasoning (Gf): The deliberate but flexible control of attention to solve novel “on the spot” problems that cannot be performed by relying exclusively on previously learned habits, schemas, and scripts. Fluid reasoning is a multi-dimensional construct but its parts are unified in their purpose: solving unfamiliar problems. Fluid reasoning is most evident in abstract reasoning that depends less on prior learning. However, it is also present in day-to-day problem solving. Fluid reasoning…
