cognitive load

Cognitive load is the concept of the amount of mental effort a person must remember and think about to complete a task. Cognitive overload means there is too much to remember and think about. Cognitive load is a theory initially applied to education by educational psychologist John Sweller as one of the ways to help learners efficiently remember what they have learned.

There aren't many things I can briefly remember. - human memory

To act, you must think, and to think, you must remember information. Human memory is divided into short-term memory and long-term memory. Short-term memory is the collection of only the information you need right now, and long-term memory is the collection of information that will be used for a long time in the future. Short-term working memory is important in experience design. Working memory is a system that remembers information for a short period of time to perform a complex task, because it is important to make the product act in a short moment, usually less than 1-2 seconds on a digital device. In this brief moment, the amount a user can remember is limited. That's why there is a need to increase the load of information needed to complete a task and reduce the load of unnecessary information. Reference - Miller's Law

What I have to do is difficult. – Intrinsic cognitive load

Intrinsic cognitive load is the load on the difficulty of the task itself being solved. “Please enter your itinerary.” and “Reserve a private pension that can be used on June 8, 2021, has two bathrooms, five rooms, and grills meat outside.” It is the difference between the same task. When designing a user experience, we think about how to make a task feel easier to drive action.

Reducing Intrinsic Cognitive Load

• Divide by what you can afford
• Show step by step from simple to complex
• Linking new information to prior knowledge
• Presenting what to learn in advance
• Categorize by grouping several
• Put only one message on one screen
• Use close-to-summary titles

I'm getting in the way of doing this. – Extrinsic cognitive load

It is literally the cognitive load caused by external factors. It's about unnecessary cognitive effort in how information is organized or conveyed to accomplish a task. This is one of the issues we often encounter when creating products with product makers. Extrinsic cognitive load increases when you have information that is not essential to solving the task at hand.

Reducing Extrinsic Cognitive Load

• don't overstimulate
• Don't show too many options at once
• Avoid showing too much content at once
• Express the same function in a unified way
• Bring out the features you need for your core flow in an easy-to-find way
• Eliminate the +a flow, which is not related to the core flow, but is a little helpful
• Don't ask for multitasking
• Avoid conceptual overlap between images and text

Oh, you can do it like this. – Innate cognitive load

Unlike the previous two cognitive loads, innate cognitive load is a positive load. It is the cognitive load that occurs when a person understands the context of information, reconstructs it, and connects it to previously known information so that it can be remembered for a long time. This cognitive load is important because the ultimate goal of learning is to acquire new knowledge and retain it for a long time.

Increasing the Innate Cognitive Load

• Use the same experience as in the OS (iOS, Android)
• Providing patterns of other services that are frequently used in daily life
• Linking or substituting experiences in real life
• Comparing information to something similar in structure but easy to memorize
• Use icons or wording that are used elsewhere
