A large body of research has found that the neurotransmitter dopamine affects our ability to recall specific past events, so called “episodic memory.” In people, for example, researchers have found that having a greater density of dopamine receptors in the hippocampus results in better episodic memory.
Exceptional memory is the ability to have accurate and detailed recall in a variety of ways, including hyperthymesia, eidetic memory, synesthesia, and emotional memory. Exceptional memory is also prevalent in those with savant syndrome and mnemonists.
Rapidity, length of time, accuracy of recall or recognition and serviceableness are the signs of good memory. Have the intention to learn. Interest and close attention are essential for effective learning and memorization.
Genetics influence educational attainment, emotional memory, and memory performance. People with certain genetic types are more likely to have better memory and may exhibit characteristics such as rapid recall of events, be better at remembering names, and more adept at learning new skills/language.
Is good memory an indicator of intelligence? Essentially, yes, but not in the way you may think. Short-term memory storage is linked to greater signs of intelligence as measured in IQ tests. But having perfect recall isn't necessarily correlated with high intelligence.
People with high intelligence are likely to have this ability. The ability to store more items in short-term memory indicates a higher IQ, psychological research reveals. While there may be no limit to long-term memory, short-term memory is much smaller.
Our ability to remember new information peaks in our 20s, and then starts to decline noticeably from our 50s or 60s. Because the hippocampus is one brain region that continues producing new neurons into adulthood, it plays an important role in memory and learning.
New research indicates that being forgetful doesn't mean you're losing your marbles, in fact, it could mean that you are exceptionally intelligent. People with the best memories in the long term usually forget details once they are no longer needed.
Because the olfactory bulb and cortex are so close physically to the hippocampus and amygdala (huge factors in memory retention), smell is considered the strongest and quickest memory inducer.
To conclude, it seems that the reason why we remember some things more than others is due to the number of activated neurons associated with what we're trying to remember.
People with good memory, on the other hand, are referred to as eidetic. Eidetic memory or photographic memory would be the correct term.
Difficulties talking or talking late. Having problems remembering things. Inability to connect actions with consequences. Difficulty with problem-solving or logical thinking.
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.
Two-year-olds have twice as many synapses as adults. Because these connections between brain cells are where learning occurs, twice as many synapses enable the brain to learn faster than at any other time of life.
Having a high IQ with a lower working memory means that that child needs to learn the strategies that go with supporting the lower working memory. Now, the trick here is if his IQ is in the 90th percentile or above and his working memory is in the 75th percentile, his working memory is still way above average.
Scientists have said that people who forget small details like birthdays, names, or where you kept your car keys may bear signs of higher intelligence. Memory lapses are normal and there is no need to worry about forgetting things, say researchers.
Ability to learn new topics quickly. Ability to process new and complex information rapidly. Desire to explore specific topics in great depth. Insatiable curiosity, often demonstrated by many questions.
Research shows that the signs of intelligence are usually good memory and thinking ability, good attitude and hard-working nature, general and tacit knowledge, language proficiency and reasoning, decision-making, trust, creativity, achievements, good intuition, and problem-solving.
Hyperthymesia, also known as hyperthymestic syndrome or highly superior autobiographical memory (HSAM), is a condition that leads people to be able to remember an abnormally large number of their life experiences in vivid detail.
