For the first time, an IQ of 81 is a performance that reaches <15% of the population.
An IQ of 81 is just below the average standard deviation (sd).
The average IQ is between 85-115.In addition, one is considered to be above average intelligent (sd 1), including as below average intelligent (sd -1). 2/3 of the population are between 85-115 and 1/3 is either <85 or >115. An IQ of 70 is as rare as an IQ of 130.
Someone with an IQ of 70 performs better than 2.3% of the population, which means that 97.7% of the population performs better or equal.
The pace of learning is delayed and certain skills are lacking.
Someone with an IQ of 130 performs better than 97.7% of the population, which means 2.3% of the population performs better or equal.The pace of learning is increased and certain skills are more pronounced.
Two important building blocks of the intelligence quotient are:
- logical mind
- working memory
What is logic?
Logic helps us to link different information.By linking information, we can draw conclusions.
As an example: I know you have big feet and I have two different sized shoes in my hand because I know that you have big feet I will logically take the bigger shoe.
That was a logical conclusion.
What is working memory?
It is a certain area of the brain (the prefrontal cortex) that is responsible for allowing us to briefly remember something and manipulate information.
Without working memory, we could not calculate, read, write or think logically.
Without working memory, we would not be able to access our skills and perceive and process our environment.
Through working memory, we perceive information and process it.
By processing the information, we understand the information.
An IQ test asks for things that work on working memory.The faster the working memory processes things, the higher the IQ.
In a nutshell: The faster the working memory processes information, the faster one understands the processed information and the higher the IQ.
In everyday life, the person with the IQ of 81 will take longer to perceive and process the information than the average.
In everyday life, the person with the IQ of 130 will perceive and process the information faster than the average.
