Do you get less intelligent as you age?

The findings revealed that processing speed and short-term memory for family pictures and stories peak and begin to decline around high school graduation; some visual-spatial and abstract reasoning abilities plateau in early adulthood and begin to decline in the 30s; and other cognitive functions, such as IQ and working memory, plateau in early adulthood and begin to decline in the 30s. These results suggest that the most important factor for predicting how an individual will perform on standardized tests is not their age but rather their current level of education and training.

Do cognitive abilities change during adulthood?

Adulthood Cognitive Development Cognition evolves over time, peaking at the age of 35 and gradually falling in later adulthood. The rate of decline varies for different cognitive functions, with some abilities showing minimal loss and others showing significant loss.

Cognitive abilities continue to develop well into old age, but they are not immutable; rather, they are malleable and can be improved through learning new skills and strategies. Older adults may even show improvements in certain areas of cognition such as problem-solving ability or memory function compared to younger adults.

The most famous example of this is that of Benjamin Franklin, who at the age of 84 was able to publish a pamphlet describing the benefits of air travel when everyone else believed it was impossible. Other examples include other famous people who showed improvement in specific tasks such as Alice Walker's writing skill after she started writing more than before, and Mark Twain's ability to write longer and more complex sentences at 77 than he could at 37.

However, not all older adults experience improvement on cognitive tests. Some studies have shown that many individuals suffer from mild cognitive impairment (MCI), a condition that increases your risk of developing Alzheimer's disease and other types of dementia.

Does practical intelligence decline?

Practical intelligence tends to peak around the middle of life and subsequently diminish, closely mirroring changes in the underlying cognitive capacities connected with specific everyday difficulties. Practical intelligence declines more rapidly than general intelligence.

Research studies have shown that people's IQ scores decrease by an average of about five points per decade after age 30. This is because certain parts of brain that are important for reasoning and problem solving start to shrink during this period of our lives. However there are individual differences in how fast each person's brains begin to shrink, so someone who starts to lose IQ years before others their same age might be able to compensate by developing other skills or learning new ways of thinking about problems.

Intelligence is a fairly stable trait, which means that people who are very intelligent tend to stay that way over time. This isn't always the case; some people lose interest in ideas that were interesting to them as children but not as adults, while others acquire new interests that weren't evident earlier in life.

In addition, there are times when people may need to use their intelligence in order to survive. For example, if you're injured and can't think for yourself, you will need somebody who can help you solve problems and get through difficult situations.

Do old people lose intelligence?

The researchers publish in the Cell Press journal Current Biology on August 4 that age-related decreases in intelligence are closely connected to losses in a fairly simple task of visual perception speed. "As this fundamental skill deteriorates with age, so does intellect."

They looked at the vision abilities of more than 795 adults aged 20 to 102. The participants took tests of their visual perception and memory skills every four years as part to a national health survey. They also answered questions about their current intellectual ability (which the scientists call "general cognitive capacity") and how it changed over time.

They found that general cognitive capacity declines at a constant rate of one point per year, regardless of whether you're young or old. This means that if you start off at 21 with 100 points, you'll have 101 points after one year, 102 points after two years, and so on.

But what happens to your IQ score? It depends on how long you live. If you make it to 90, you can be sure that your IQ will have dropped by about three points. But if you reach 105, the study shows that it's only lost about two points.

So yes, old people do lose intelligence - especially those who live long enough to become very old. The more years you live, the less likely you are to suffer a serious mental impairment.
