Cognitive load is the effort used by the working memory to process information. The working memory capacity is limited: If it is overloaded with information, you will fail to understand.
There are three types of cognitive load:

Chunking is the secret behind mastering any subject. Chunking draws on your long-term memory resources. The more knowledge you have stored, the less information you need to process with your working memory, and the easier it will be to understand and remember your study material.
To master any subject:
Working memory temporarily stores the information you are working on. But it is not just a simple storage. The working memory enables you to create new thoughts, change them, combine them, search them, or any other function that helps you navigate your life.
By enabling these functions, working memory upholds your thinking, planning, learning, and decision-making.
Anxiety is a major cause of cognitive load. Instead of your working memory focusing on the task at hand, your short-term memory is filled with irrelevant information. i.e. maths is hard; I hate math; I want to give up.
The visuospatial sketchpad is essential for understanding mathematical, science, technology and engineering subjects.
You can improve your visuospatial working memory. There are two broad strategies for approaching visuospatial problems.
You can use your visuospatial sketchpad to help your phonological loop and vice versa.
If you practice this skill, you can improve it. To set out how to improve your working memory, it is useful to know how you can measure it.
There is a difference between short-term memory capacity and working memory capacity.
The working memory model of Alan Baddeley divides the working memory into four components:
A phonological loop is a kind of short-term memory storage that stores sound. A conversation, listening to music, and understanding a lecture depends on your phonological loop.
As you read, your phonological loop uses sub vocalisation (your internal voice) to translate visual information (what you read) into auditory information, which is then processed to extract meaning. If your internal voice is disrupted, you will find it hard to maintain information in your phonological loop, and your comprehension will suffer.
The idea behind chunking is to group underlying items by some sort of meaning or structure. For example, RTCTAIILFSO is easier remembered when it is regrouped to FRAC-TO-LIS-TIC.
To learn, you must first understand. To understand,
If any of these processes fail, you'll get confused.
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.
Adults and babies alike dream for around two hours per night—even those of us who claim not to.
Researchers have found that people usually have several dreams each night, each one typically lasting for between five to 20 minutes.
