So, at what age does intelligence peak? It’s later than you might think. How Does Intelligence Change With Age?īoth crystallized and fluid intelligence change throughout life. This shows how crystallized and fluid intelligence are interwoven. You must have some advertising knowledge to develop the campaign. However, you use previously-acquired facts to do so. In this scenario, you are solving a new problem using fluid intelligence. Your boss wants you to come up with a new advertising campaign for a client. For example, let’s imagine that you work in a large advertising firm. That being said, you do need crystallized intelligence to operate your fluid knowledge. Without it, you wouldn’t be able to solve problems that you’ve never encountered before. However, fluid intelligence is just as important in everyday life. When figuring out how much something costs after a discount, you need crystallized intelligence to recall basic math facts. Assembling a piece of furniture using a diagramīoth types of intelligence are equally essential.Navigating a complicated subway system in the city that you have not been before.Here are a few examples of fluid intelligence: Abstract thinking and problem-solving ability play a big Relationships and patterns that are involved in novel problems and arrive at a Fluid knowledge also includes the ability to identify Fluid intelligence is independent ofĪcquired knowledge.

Crystallized intelligence is reflected in your vocabulary, general knowledge, and memory. It relies on previously-acquired knowledge. What Is Crystallized Intelligence?Ĭrystallized intelligence is the ability to use information and skills that one has gained through experience or learning. This theory proposes that a person’s intelligence consists of different abilities that work together to form overall intelligence. Cattell came up with these concepts.Ĭattell, together with his student John Horn, developed the Cattell-Horn theory of fluid and crystallized intelligence. There are two main types of intelligence: crystallized and fluid. What comes to mind when you think of intelligence? Is it the accumulation of facts? Or, the ability to solve complex puzzles? Intelligence is more complicated than that.

The same type of correlation was calculated within the two different groups, and the results showed correlation of -.338 for the group without hearing loss and one of -.303 for the group with hearing loss.

The overall correlation between speech-in-noise recognition and fluid intelligence was -.317, which shows that a better (lower) score on the speech-in-noise test is correlated to a better score in the Raven’s test. Around half of the participants (n = 199) had documented hearing loss and were hearing aid users, while the rest were participants with normal hearing. The speech-in-noise test consisted of matrix sentences with 4-talker babble as noise and fluid intelligence was represented by the score on a Raven’s Progressive Matrices test. Data from a sample of 394 participants from the n200 database (Rönnberg et al., 2016) was used to calculate the correlation between their performance on a speech-in-noise test and their score on a test measuring fluid intelligence. The link between speech-in-noise recognition and cognition has been researched extensively over the years, and the purpose of this thesis was to add to this field. 2020 (English) Independent thesis Basic level (degree of Bachelor), 12 credits / 18 HE credits Student thesis Abstract
