Crystallized intellect grows stronger as we mature and gain new information and wisdom. As one might assume, this sort of intellect grows with age. 2. The more you study and experience, the more your crystallized intellect grows.
Completing tasks requiring language mechanics (such as vocabulary growth) and broad knowledge requires crystallized intellect. Crystallized intellect grows gradually and steadily throughout adulthood, until it begins to drop at the age of 60. (Cavanaugh & Blanchard-Fields, 2006).
The growing brain is also responsible for our increasing mental capacity during midlife. A study conducted at Harvard University found that the volume of the hippocampus, a part of the brain important for memory formation and storage, increases from 25 years old to 55 years old before starting to shrink.
In conclusion, intelligence remains constant or increases with age.
4: Crystallized intellect tends to peak later in life, around the age of 60 or 70. It's based on your experience and what you know. So the more knowledge you acquire through learning new things and communicating ideas, the higher your crystallized intellect will be.
5: Fluid intellect stays constant throughout your life. It's based on your ability to think quickly on your feet, solve problems, come up with innovative ideas, etc. So if you improve your fluid intellect by reading books on psychology, thinking critically, using logic, etc., then it will keep rising even after you reach old age.
6: Sensory intellect starts low at birth and then gradually improves until about age 10 when it reaches its peak. It's based on your sense of hearing, sight, smell, taste, and touch. So the better your sensory intellect is at a young age, the more likely you are to become an expert player of music, game, or sports before you grow up.
7: Intuition rises from childhood to adulthood. Most people believe their intuition gets better as they get older, but scientific studies have not confirmed this. However, there are two types of intuitions - logical and emotional.
While crystallized intelligence would continue to improve throughout adulthood, fluid intelligence would peak in the early 20s and begin to diminish between the ages of 30 and 40. Since then, this has been the dominant intelligence hypothesis. However, some recent studies have suggested that fluid intelligence may actually increase after 60 years of age.
The most widely accepted explanation for this decline is the resource depletion model. This model states that because fluid intelligence requires active processing, it is vulnerable to the effects of aging brain cells known as neurons. The more neurons there are in a given area of the brain, the higher their cognitive function is likely to be. Neurons are lost to disease and aging through death or degeneration. They can be regenerated though, which allows for some recovery of function after severe damage.
According to this model, the greater the number of neurons that exist in the brain at any one time, the better their functionality will be on average. Because fluid intelligence requires the use of many different areas of the brain, its capacity is limited by the number of neurons that can be used at once.
Throughout maturity, crystallized intellect grows. Many components of fluid intelligence peak in adolescence and begin to deteriorate gradually around the age of 30 or 40. There is evidence that new learning can revitalize certain aspects of fluid intelligence, but this effect appears limited to simple tasks, such as answering multiple-choice questions or matching symbols with their definitions. Older adults who continue to work with information technology tend to improve their visual perception and memory processing speed.
The majority of research on cognitive aging has focused on the effects of age on specific cognitive abilities. However, it is well known that people become impaired at different tasks depending on their own traits and circumstances. For this reason, it is important to examine not just how many things older adults can't do, but also how well they perform on various tasks. The results of such studies can help us understand what factors influence cognitive ability and allow us to identify potential remedies for impaired function.
It is widely accepted that there is a positive correlation between education level and cognitive ability. People who have been to school tend to do better on neuropsychological tests than those who have not. This may be because more educated individuals have better nutrition and health habits, which are both necessary for healthy brain function. They may also have access to better jobs and social opportunities that provide stimulation to the mind and body.
