In the past 10 years, if you are an inquisitive adult, we would have guess that you would have probably had your fair share of IQ tests. Be it physical test papers or the online questionnaires, we’ve all played our part. But how many adults have actually participated in a cognitive assessment before? How far are we in terms of our cognitive functions?


So, what exactly does IQ means?

Well in the more common content, we would simply refer to it as ‘Intelligence Test’.

Here’s the definition from HowStuffWorks:

The term IQ, or Intelligence Quotient, generally describes a score on a test that rates the subject’s cognitive ability as compared to the general population. IQ tests use a standardized scale with 100 as the median score.

It is important to note that IQ is only ONE of MANY ways to determine intelligence. There are many other tests such as Stanford-Binet Intelligence Scale or even SATs which is commonly used for college admission,

In fact, IQ is typically static with minimal changes even though it can be influenced by a wide range of factors such as family environment, parenting style and even work environment. The reason why there are minimal changes is because individuals are settled into their current environment and maintain a status quo (Schenk, 2009).

 


Then we come to cognitive functions. What exactly does it refer to?

Definition of ‘Cognitive Functions’ by Mosby’s Medical Dictionary (2009) & McGraw-Hill Concise Dictionary of Modern Medicine (2002):

An intellectual process by which one becomes aware of, perceives, or comprehends ideas. It involves all aspects of perception, thinking, reasoning, and remembering.
Any mental process that involves symbolic operations. Example: perception, memory, creation of imagery, and thinking. Cognitive functions encompasses awareness and capacity for judgment.

 

Edwards (2014) has mentioned that cognitive functions differ from IQ in the sense that certain brain exercises and cognitive skills activities, can help to train and develop our cognitive functions. This means that it can be improved over time!


When conducting these tests, there would also be different areas tested. Please see table for a better overview:

IQ Test

Cognitive Functions

Spatial Ability- Perceive and orientate spaceMotor Skills
Mathematical AbilityAttention
Memory & RecallPerception
Language AbilityExecutive Functions- Working Memory- Reasoning- Task Flexibility– Problem Solving– Planning– Execution

 

Sometimes being book smart or grades smart does not necessarily determine how successful you would be.

Needless to say, every person would likely want to be in tip top condition and performing optimally when they go around their daily routines. Value and appreciate what you have, work on areas that you can improve in, and keep a positive outlook on things.

These tests are only the basics which allows individuals some insight to their current performance and not definitive of an individual’s capability in the long run!
