Fluid intelligence is the ability to think flexibly and to understand abstract relations. People with high fluid intelligence (hi-fluIQ) perform better in analogical reasoning tasks than people with average fluid intelligence (ave-fluIQ).
Fluid intelligence has been defined as the ability to think logically and solve problems in novel situations, independent of acquired knowledge [1].
Examples of the use of fluid intelligence include solving puzzles, constructing strategies to deal with new problems, seeing patterns in statistical data, and engaging in speculative philosophical reasoning (Unsworth, Fukuda, Awh & Vogel, 2014).
The IQ is commonly divided into two factors: fluid and crystallized intelligence. Fluid intelligence refers to the capacity to solve and think logically about novel problems.
Studies have demonstrated that the training effect of working memory can be far transferred to fluid intelligence and other cognitive abilities (Jaeggi et al., 2011). Zhao et al. (2011) reported that the fluid intelligence of children was significantly improved after they had received working memory training.
Fluid intelligence (Gf) is defined as reasoning ability, and the ability to generate, transform, and manipulate different types of novel information in real time.
General fluid intelligence, the important component of human cognitive ability, has been reported under genetic control. Moreover, the correlation between general fluid intelligence and cortical structural measures has been identified.
For example, raw speed in processing information appears to peak around age 18 or 19, then immediately starts to decline.
Fluid intelligence is the ability to reason quickly and to think abstractly.
Fluid intelligence refers to ones ability to reason and solve new problems without relying on prior knowledge. Fluid intelligence is important for a range of cognitive tasks, and it is regarded as one of the most crucial aspects of learning.
Background: Fluid intelligence declines with advancing age, starting in early adulthood. Within-subject declines in fluid intelligence are highly correlated with contemporaneous declines in the ability to live and function independently.
The fluid intelligence test is a non-verbal test with questions on Raven's progressive matrices & spatial reasoning to identify candidates who can think abstractly & solve problems independent of previously acquired knowledge.
Fluid intelligence tends to decrease with age while crystallized intelligence tends to increase with age.
Fluid intelligence is thought to be a key feature involved in "active thinking" -- a set of complex mental processes such as those involved in abstraction, judgment, attention, strategy generation and inhibition.
On average, fluid abilities decline throughout adulthood, whereas crystallized abilities show gains into old age.
Crystallized and fluid intelligence are the two paramount secondary mental abilities that are often mentioned in the literature.
Cattell and Horn thought that both types of intelligence increased throughout childhood and adolescence. However, while crystallized intelligence would continue to make gains through adulthood, fluid intelligence would peak in the early 20s and then start to decline between ages 30 and 40.
What age is your mind the sharpest? The human brain attains peak processing power and memory around age 18. After studying how intelligence changes over time, scientists found that participants in their late teens had the highest performance.
Fluid intelligence is trainable to a significant and meaningful degree. Jaeggi et al.'s article (10) is important to the field of intelligence because it shows that training can improve fluid intelligence, can do so across intelligence levels, and can do so in a theory-based way.
Fluid intelligence allows flexible recruitment of the parieto-frontal network in analogical reasoning. Fluid intelligence is the ability to think flexibly and to understand abstract relations.
Fluid intelligence is the ability to solve newly encountered problems based on logic and reason. It is the opposite of crystallized intelligence which involves stored intelligence based on experience and wisdom.
A person with high fluid intelligence can navigate through new situations, solve problems, and deduce patterns. Can fluid intelligence be increased with practice? According to one study, it's entirely possible.
The most accepted evidence suggests that age-related atrophic changes take place prominently in frontal brain structures which undermine the functioning of executive abilities, thereby, resulting in gradual decline of fluid intelligence [11].
That said, science has indicated that learning is most effective between 10 am to 2 pm and from 4 pm to 10 pm, when the brain is in an acquisition mode. On the other hand, the least effective learning time is between 4 am and 7 am.
Examples of fluid reasoning include: Playing a new game or solving a new puzzle, like Kanoodle or a Rubik's cube. Seeing patterns in statistical data. Getting lost in an unfamiliar place and having to find your way around.
