Miller`s Law Examplesngocthanh
These examples show how segmentation can be used to visually organize content for ease of understanding. It helps those who consume the content to understand the underlying relationships and hierarchy of information. What segmentation does not do is set a certain limit on the number of items that can be displayed at any given time or within a group. Rather, it is a method of organizing content that makes it easy to quickly identify important information. Next, we analyze the use of Miller`s law in UX design and look at some examples of its use. Miller`s law states that people`s immediate memory span is limited to about seven elements plus or minus two. 3 Wei Ji Ma, Masud Husain and Paul M. Bays, “Changing concepts of working memory,” Nature Neuroscience 17, No. 3 (2014): 347-356. Simply put, fragmentation refers to the breakdown of content into digestible and disparate information, rather than presenting a single large piece.
This term was introduced by Miller in his 1965 paper and is actually a popular memorization technique that you also use very often. If we compare this example to content that has appropriate formatting, hierarchy, and line lengths, the contrast is significant. Figure 4-3 is an improved version of the same content. Headings and subheadings were added to create a hierarchy, spaces were used to divide content into recognizable sections, line length was reduced to improve readability, text links were underlined, and keywords were highlighted to contrast with surrounding text. “The most important thing UX designers need to understand about Miller`s Law is that short-term human memory is quite limited, so if they want to increase knowledge storage, they should use fragmentation,” says Clara Lago, UX Designer at A-writer. His explanation of this phenomenon was a new theory called “pieces.” He dealt with our “working memory”: the brain`s ability to actively store several bits of information and our ability to make judgments with these objects. Some of the most common mistakes include adding huge menus, long lists of elements, too many design elements, and large blocks of written content to your website, which can lead to information overload and increase your bounce rate. Let`s say you have one minute to memorize 20 words and another minute to remember them. Chances are you`ll remember about 5-9 words. This 7 ± 2 ability is a universal phenomenon that has been tested in several experiments.
Do you like reading walls of text? Of course not. No one does. For this reason, written content should be broken down into smaller, digestible chunks to make it easier to digitize and understand key points. A good design interface takes into account how users think and organize content to complement their goals. Cognitive load is the amount of information that our working memory can store at the same time. Just like Fitt`s law in the user interface, when you start searching for it, you`ll find that Miller`s law is everywhere in UX design. Here`s how you can apply the psychology behind Miller`s Law to your designs: It`s important to remember that Fitts` Law generally doesn`t apply to mobile devices. Although there is no cursor to reach a target location, a designer can use the distance from one faucet to another to hinder or sustain an interaction. For example, a “logout” icon can be placed at the top of the mobile screen, and the confirmation can be displayed at the bottom.
The use of aesthetic and content-friendly typography reduces distraction for the reader. This, in turn, will reduce their cognitive load, leading to a better understanding of the content. Far from an old, dusty legal theory, this includes the tracks, Netflix and the magic number seven. The more choices users have, the longer it takes them to make a decision. Too many decisions lead to decision paralysis and, as a result, a frustrating experience. O`Reilly members receive live online training as well as books, videos and digital content from nearly 200 publishers. A cousin of Miller`s law is Hick`s law, which states that “the time it takes to make a decision increases with the number and complexity of decisions.” It`s easy to see how they are related. In a poorly designed scenario, these two laws could be violated simultaneously by a user interface that offers too many choices and asks users to remember too many things when trying to accomplish a task. The father of streaming sites seems to have set himself on six as a magic number. Each menu and carousel is presented on the homepage as a separate part and offers six options. Like a hack to expand these limitations, our brains unconsciously group pieces of information into smaller pieces and small pieces into larger pieces.
For example, the ability to distinguish between two letters is a bit, and the ability to distinguish between two words is a piece. However, bits and pieces have the same limitations of 7 ± 2. User experience design is not about designing fancy websites and apps. It`s about making sure customers have a seamless experience with your products and can easily achieve their goals. Present your content in a clear, concise and useful way. Stick to other good rules for writing user experiences to reduce cognitive load and help people navigate your website easily. In other words, the number of bits that can be reliably transmitted over a channel (your short-term memory) under certain time constraints is about seven. An easy way to remember this is the magic number seven. It`s possible to have a list of password requirements and not overwhelm your customers. Good UX design follows the psychology behind Miller`s Law by presenting important information in a clear and concise manner. Through controlled experiments, Miller found that exceeding the number of “bits” of information on this threshold caused confusion, leading to false judgments. He called this point “channel capacity.” The organization of elements into 7 ± 2 pieces has become a common phenomenon in UX design.
But while some see this ~7 magic number as a rule, others see it as a suggestion that context and other factors play an important role in the decision to organize content.

Now that we know what it is, how does it work in reality? German psychologist Hermann Ebbinghaus is credited with coining the term “serial positional effect”. The serial position effect is a person`s tendency to remember the first and last elements of a series best and the worst middle elements. The isolation effect (also known as the Von Restorff effect) is the tendency to remember something that stands out in a group and gives it more weight than its colleagues. It is named after the German psychologist Hedwig von Restorff, who first documented it in 1933. Fitts` law shows how interactions can be facilitated by carefully sizing and positioning interface elements. The time it takes to capture a target depends on the distance and size of the target. This is especially important when designing buttons and other clickable screen elements. For most people, numbers are easier to remember in small groups of 3 or 4, as follows: 2 Nelson Cowan, “The Magic Number 4 in Short-Term Memory: A Reconsideration of Mental Storage Capacity,” Behavioral and Brain Sciences 24, No. 1 (2001): 87-114. The amount of information around us is growing exponentially – but we humans have a limited amount of mental resources available to process that information.
