There are many definitions of intelligence, and all of them have something in common – the ability to use logic and abstraction, to understand the world around us, to develop self-awareness, to reason, to plan, to be creative, and to solve problems. These are just some of the many abilities we are capable of, and each has its place in the spectrum of human abilities.
Multiple intelligences theory
The Multiple Intelligences theory posits that there are multiple modalities of human intelligence. These modalities include language, mathematics, science, and other skills. The theory also suggests that intelligence is separated into various general abilities. This division is crucial in understanding why certain people excel at specific tasks and others do not.
Teachers must understand each student’s distinct intelligence to teach students more effectively. This theory aligns with science and offers a way to identify and differentiate instruction. Children as young as four exhibit different strengths and weaknesses within different types of intelligence. This helps teachers differentiate instruction and help students learn more complex concepts.
Fluid intelligence
Fluid intelligence is the type of human intelligence that is based on fluidity. It is a general intelligence that differs from crystallized intelligence. Its origins can be traced back to the work of Raymond Cattell in 1963. He developed a psychometrically-based theory that divided general intelligence into two types, gf and GC.
Our processing speed influences fluid intelligence. As our processing speed increases, we can better recall information from our long-term memory. This improves working memory and the skills that use it. Research shows that the improvement of working memory is good support for the development of fluid intelligence. Gemm Learning is one such method that uses brain-based software to help individuals improve their working memory. It has been proven to increase IQ scores.
Crystallized intelligence
In 1963, Raymond Cattell introduced the concepts of fluid and crystallized intelligence. This psychometrically based theory subdivided general intelligence into two levels: gf and GC. The underlying principles of both types of intelligence are similar and differ only slightly. However, their main differences lie in how they measure intelligence.
Essentially, crystallized intelligence is a sum of knowledge acquired through learning. This can be either formal (such as reading or studying) or informal (like taking on new tasks). It is important to note that a person’s crystallized intelligence will diminish if he doesn’t engage in enough new learning. Trying new things is the best way to sharpen our crystallized intelligence.
IQ tests
IQ tests are widely used to determine a person’s intellectual potential and whether they are likely to be successful in school or the workplace. This test focuses on an individual’s reasoning and critical thinking abilities. It can also identify a person’s learning needs.
An IQ test measures a person’s cognitive ability and is divided into three domains: verbal, nonverbal, and social. Historically, IQ tests were based on a formula. For example, if a 10-year-old scored the same as a 13-year-old, they would have an IQ of 130 (100 + 13/10). Now, IQ is calculated in a mathematically transformed ranking system. The scores are also often referred to as “deviation IQ” or “ratio IQ.”
g-factor
The g-factor is a psychometric construct that measures cognitive abilities. It is used to determine human intelligence. The test is not entirely reliable, but it can provide a good idea of an individual’s intelligence level. Many tests measure the g-factor, including the SAT and the ACT.
In the past, psychologists have been trying to quantify intelligence and determine what factors influence it. They have developed tests and conducted research in schools, militaries, and corporations to try and separate individual differences in intelligence. Eventually, they came up with the concept of the “g-factor.”
