The limited amount of load we can take on our working memory, which functions like computer RAM, is called the cognitive load. 
Miller's Law states that we need to limit our cognitive loads and hold on to approximately seven number of objects at a given time.

Our Working Memory

To increase our learning performance, we need to balance our cognitive load. It helps to understand what the three types of cognitive loads are:
<ol>
<li>Intrinsic cognitive Load: The inner load we feel when we are calculating something complex. This is a fixed load on the brain.</li>
<li>Extraneous cognitive load: Presenting information or a task in a certain way, like visually or verbally, making it easier to understand.</li>
<li>Germane cognitive load: It is the flow-chart constructions of the brain, which help in long-term learning. The mind makes information easier to grasp by creating maps and inner processes, helping us understand better.</li>
</ol>

Balancing Our Mental Effort

<ol>
<li>Grouping or chunking of various pieces of information into different sections, making them easier to retrieve and remember.</li>
<li>Making mind maps or process maps, and also thinking in maps making constructive associations and flow-charts.</li>
<li>Clearing your mind by taking your thoughts out of it and projecting it where they are better visualized. This is also known as brain-dumping, and writing is a good way to understand context, build associations and improve memory.</li>
<li>Collaborating with others using brainstorming sessions, Idea-meets, or creating a learning plan together as a team, confluence style.</li>
</ol>

Tools To Manage The Cognitive Load

There’s only so much we can hold into our working memory—the system our brain uses to temporarily hold information while we manipulate it. The amount of working memory we use at any given moment is called the cognitive load. While both are theoretical concepts used in psychology and neuroscience, they have profound implications when it comes to thinking, learning, problem-solving, and decision-making.Most people think we need to reduce our cognitive load as much as possible. But things are a bit more subtle than that. Certain types of cognitive loads can’t be altered, others are detrimental, and yet others are actually productive. Better thinking requires finding the delicate balance between all the different types of cognitive loads so you can make the most of your working memory.<h2>The magical number seven</h2>The classic paper The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information is one of the most cited ones in psychology.
