 3r33469. 3r3-31. [Психология дизайна ]- The Psychology of Design to be encoded [/s] be able to write code and understand business? These skills are incredibly valuable, but perhaps not essential. However, I would say that every designer should learn the basics of psychology. As humans, we have a basic “plan” of how we perceive and process the world around us, and studying psychology helps us define this plan. As designers, we can use psychology to create more intuitive, people-oriented products and experiences. Instead of forcing users to adapt to the design of a product or experience, we can use some key principles from psychology as a guide to design a design for a model of human behavior. 3r33424.  3r33469. 3r33424.  3r33469. But the problem is where to start? What principles from psychology are useful? What are examples of these principles in the work? In this article we will look at the basics and discuss the ethical implications of using psychology in design. 3r33424.  3r33469. 3r33424.  3r33469. good communication tends to clarity . This is directly related to our first key principle: Hick's law. Hick's law predicts that the time needed to make a decision increases with the number and complexity of the options available. It was formulated by psychologists William Edmund Hick and Ray Hyman in 1952 after examining the relationship between the number of stimuli present and the response time of a person to any given stimulus. 3r33424.  3r33469. 3r33424.  3r33469. It turns out that there is an actual formula for representing this relationship: RT = a + b log2 (n) . Fortunately, we do not need to understand the math of this formula in order to understand what it means. The concept is quite simple: the time required for users to respond directly correlates with the number and complexity of the options available. This means that complex interfaces lead to an increase in processing time for users, which is important because it is associated with a fundamental theory in psychology, known as cognitive load. 3r33424.  3r33469. 3r33424.  3r33469. 3r33336. Cognitive load
3r33424.  3r33469. 3r3402. Cognitive load [/i] refers to the mental computing power used by our working memory. Our brains are like computer processors, because we have limited computing power: when the amount of information entering it exceeds the available space, a cognitive load arises. Our productivity suffers, and the tasks become more complex, which leads to missing parts and even to disappointment. 3r33424.  3r33469. 3r33424.  3r33469. 3r33418. Examples 3r33419. 3r33424.  3r33469. 3r33424.  3r33469. 3r3633. 3r33424.  3r33469. 3r33424.  3r33469. 3r3402. Modified television consoles that simplify the “interface” for grandparents 3r3403. 3r33424.  3r33469. 3r33424.  3r33469. There are examples of Hick's Law all over the world, but we will start with a general: remote control. Over the past decades, many new functions have appeared on televisions, which could not but affect the control panels for them. In the end, the consoles were so complex that their use required either muscle memory from reuse or a significant amount of mental processing. This led to a phenomenon known as the “understandable console for grandparents”. By gluing everything except the main buttons, the grandchildren were able to improve the usability of the remotes for their loved ones, by sharing this invention online, they did us a big favor. 3r33424.  3r33469. 3r33424.  3r33469. gone mad 3r3105. overloaded, Slack hides all features except message entry. And when users already know how to communicate through Slackbot, they gradually open up additional functions. 3r33424.  3r33469. 3r33424.  3r33469. This is a more effective way to introduce users, because it mimics how we actually learn: we count every subsequent step and add to what we already know. By opening functions at the right time, we allow our users to adapt to complex workflows and sets of functions without feeling overwhelmed. 3r33424.  3r33469. 3r33424.  3r33469. 3r33336. Highlights

3r33424.  3r33469. 3r33424.  3r33469. 3r33336. MILLER'S LAW
3r33424.  3r33469. Another key principle is Miller's Law, which predicts that the average person can only store 7 (± 2) elements in his RAM. It stems from an article published in 1956 by cognitive psychologist George Miller, who discussed the limits of short-term memory and memory. Unfortunately, over the years there has been a lot of misinterpretation regarding this heuristic, and this has led to the fact that 3r3138. “Magic number seven”
used to justify unnecessary restrictions (for example, restricting the interface menu to no more than seven elements). 3r33424.  3r33469. 3r33424.  3r33469. 3r33336. Fragmentation
3r33424.  3r33469. Miller’s passion for short-term memory and memory was not focused on the number ? but on the Fragmentation concept and our ability to remember information. When applied to design, Fragmentation can be an incredibly valuable tool. It describes the action of visually grouping related information into small separate pieces of information. When we collect content in design, we effectively simplify processing and understanding. Users can scan content and quickly determine what they are interested in, which is consistent with our experience in the use of digital content. 3r33424.  3r33469. 3r33424.  3r33469. 3r33418. Examples 3r33419. 3r33424.  3r33469. 3r33424.  3r33469. 3r3158. 3r33424.  3r33469. 3r33424.  3r33469. 3r3402. An example of the fragmentation of elements such as phone numbers. 3r3403. 3r33424.  3r33469. 3r33424.  3r33469. The simplest example of Fragmentation can be found when we format phone numbers. Without Fragmentation, the phone number will be a long string of characters, which increases the complexity of processing and memorization. Alternatively, a phone number that has been formatted (fragmented) becomes much easier to interpret and memorize. This is similar to how we perceive the “wall of text” compared to well-formatted content with the appropriate heading, line length, and content length. 3r33424.  3r33469. 3r33424.  3r33469. 3r3173. 3r33424.  3r33469. 3r33424.  3r33469. 3r3402. Fragmentation can organize content so that users can easily process, understand and remember. On the right, I described how Bloomberg grouped information. 3r3403. 3r33424.  3r33469. 3r33424.  3r33469. Another example of the effective use of Fragmentation in design is the layout. We can use this method to help users understand basic relationships and hierarchy by combining content into various modules. In particular, in volume and content information, fragmentation can be effectively used to structure content. Moreover, the result is more visually pleasing and convenient when browsing. 3r33424.  3r33469. 3r33424.  3r33469. 3r33336. Highlights
3r33424.  3r33469. 3r33426.  3r33469.
Do not use the "magic number seven" to justify unnecessary design restrictions.
 3r33469.

3r33424.  3r33469. 3r33424.  3r33469. Jacoba Act 3r32424.  3r33469. The last principle we’ll review is Jacob’s Law (Jacob’s User Experience Internet Act), which states that users spend most of their time on other sites, and they prefer your site to work just like any other site. which they already know. In 200? he was introduced to 3r3207. usability expert Jacob Nielsen
, who described the custom tendency of forming expectations from the design of templates based on the generalized experience from other websites. This principle encourages designers to follow common design patterns so as not to confuse users, which can lead to higher cognitive load. 3r33424.  3r33469. 3r33424.  3r33469. 3r33336. Models of thinking
3r33424.  3r33469. I know what you're thinking: if all the websites followed the same design patterns, it would create a rather boring network. The answer is yes, it probably is. User awareness is quite a powerful tool that brings us to another fundamental concept in psychology, which is also valuable for designers: models of thinking. 3r33424.  3r33469. 3r33424.  3r33469. A thinking model is what we think we know about the system, especially how it works. Whether it is a website or a car, we form models of how the system works, and then we apply this model to new situations when the system is similar. In other words, we use the knowledge that we already have from past experience when interacting with something new. 3r33424.  3r33469. 3r33424.  3r33469. The thinking model is valuable for designers because we can match The thinking model of our users to improve their experience . Consequently, users can easily transfer their knowledge from one product or experience to another, without spending time understanding how the new system works. A good user experience becomes possible when the designer’s thinking model coincides with the user's thinking model. One of the most important tasks is to close the gap between our thinking model and our users' thinking model, and to achieve this goal we use various methods: user surveys, personalization, travel maps, empathy cards and more. The essence of all this is to gain a deeper understanding not only of the goals and objectives of our users, but also of their pre-existing patterns of thinking, and how this applies to the product or experience we are developing. 3r33424.  3r33469. 3r33424.  3r33469. 3r33418. Examples 3r33419. 3r33424.  3r33469. Have you ever wondered why controls look the way they look? This is due to the fact that the people who designed them had a ready-made model of how these elements look on the control panels in the physical world. Such elements of the form as switches, radio buttons and even buttons arose from the construction of their tactile counterparts. 3r33424.  3r33469. 3r33424.  3r33469. discomfort thinking patterns [/i] and this happens when a familiar product has suddenly changed. 3r33424.  3r33469. 3r33424.  3r33469. 3r33424.  3r33469. 3r33424.  3r33469. 3r3402. YouTube redesign in 2017 before and after comparison. 3r3403. 3r33424.  3r33469. 3r33424.  3r33469. But major redesigns do not always have to lead to a negative reaction — like Google’s example. Google has a history that allows users to choose new versions of their products, such as Google Calendar, YouTube and Gmail. When they launched a new version of YouTube in 2017 after several years of essentially the same design, they allowed desktop users to simplify their work with the new Material Design interface without having to stay on the new version. Users could view the new design, get some information, send feedback and even return to the old version if they prefer it. As a result, the inevitable mismatch of the thinking model was eliminated by simply empowering users to switch when they were ready. 3r33424.  3r33469. 3r33424.  3r33469. 3r33336. Highlights

Using existing thinking patterns, we can create a superior user experience in which the user can focus on his task rather than learn new patterns.

3r33424.  3r33469. 3r33424.   3r33469. 3r33336. Summarize:
3r33424.  3r33469. 3r33424.  3r33469. Perhaps you are thinking: “What remarkable principles, how can I use them in my projects?” Although nothing replaces the study of user behavior and specific data related to our projects, we can use these psychological principles as a guide to design development more intuitive, people-oriented products and experiences. Taking into account these principles helps us create a design that takes into account the behavior of people as opposed to being forced to adapt to technology. Brief repetition:
 3r33469. 3r33424.  3r33469. 3r33426.  3r33469.
Hick's law can help us reduce the cognitive load for users by minimizing choices and breaking long or complex processes into screens with fewer options.
 3r33469.
Miller's Law teaches us to use fragmentation to organize content into smaller clusters to help users easily process, understand, and remember.
 3r33469.
Jacob's Law reminds us that users transfer the expectations that have formed around one familiar product to another similar product.
 3r33469.
3r33424.  3r33469. Therefore, we can use existing thinking patterns to create a superior user experience. 3r33424.  3r33469. We looked at some key principles that are useful for creating more intuitive, people-oriented products and experiences. Now let's touch on their ethical implications and how easy it is to fall into the trap of exploiting user psychology. 3r33424.  3r33469. 3r33424.  3r33469. 3r33336. Ethical moments
3r33424.  3r33469. On the one hand, designers can use psychology to create more intuitive products and experiences; on the other hand, they can use it to find out how the mind works, in order to create more exciting applications and websites. Let's first consider why this is a problem, and then consider possible solutions. 3r33424.  3r33469. 3r33424.  3r33469. 3r33418. THE PROBLEM
3r33424.  3r33469. No need to go far to understand why the welfare of users, being excluded from the priority in favor of profit, is a problem. When was the last time you were in the subway, on the sidewalk or in the car, and saw how someone did not stick to your smartphone? There are some who would claim that we are at the center of the epidemic , and that our attention is held captive by the mini-computers that are everywhere with us. 3r33424.  3r33469. 3r33424.  3r33469. It would not be an exaggeration to say that the mobile platforms and social networks that connect us also put a lot of effort into sticking us to themselves, and every day they are getting better. The consequences of this dependence are well known to us: from the reduction of sleep and anxiety to the deterioration of social relations, it becomes obvious, these are unintended consequences in the race for our attention. These consequences become problematic when they begin to change how we form relationships and what we are. 3r33424.  3r33469. 3r33424.  3r33469. 3r33418. SOLUTION
3r33424.  3r33469. As developers, our responsibility is to create products and experiences that support and align with the goals and well-being of users. In other words, we must build technology to expand human experience, not replacing it with virtual interaction and rewards. The first step in making ethical design decisions is to recognize how the human mind can be used. 3r33424.  3r33469. 3r33424.  3r33469. We must also ask ourselves what we should and should not design. We may be in fairly capable teams that have the ability to design almost everything that you can imagine, but this does not always mean that we should do this - especially if the goals of what we design do not correspond to the goals of our users. 3r33424.  3r33469. 3r33424.  3r33469. Finally, we must consider metrics outside of product usage data. Data tells us a lot of things, but what they don’t tell us is why users behave in a certain way or how a product affects their lives. To understand why, we need to listen and be receptive to our users. It means getting out of the screen, talking to them, and then using this qualitative research to improve our design. 3r33424.  3r33469. 3r33424.  3r33469. 3r33418. Examples 3r33419. 3r33424.  3r33469. 3r33424.  3r33469. 3r33380. 3r33424.  3r33469. 3r33424.  3r33469. 3r3402. Google Digital Wellbeing initiative website 3r3403. 3r33424.  3r33469. 3r33424.  3r33469. It was great to see companies taking the right steps when it comes to the digital well-being of users. Take, for example, Google, which just announced tools and functions in its latest I /O event, which focuses on helping people better understand their use of technology, focus on the most important, switch off when necessary, and create healthy digital habits. Features such as an application panel that provides an overview of usage, additional control over warnings and notifications, and Parental Control to set basic digital rules for small ones, all designed to protect users. 3r33424.  3r33469. 3r33424.  3r33469. determine success by meaningful interactions
. This required, from them, the restructuring of their news feed algorithm, in order to prioritize content that is valuable to people over meaninglessly consumed information. Now content from friends and family takes precedence, even if the result means that users spend a little less time on their application. 3r33424.  3r33469. 3r33424.  3r33469. These examples are just a look at the steps that many companies are taking, and I hope that more companies will join in the coming years. Technology, in which we play the role of designers, can significantly affect the lives of people, and it is essential to ensure a positive impact. We are responsible for creating products and experiences that support and are consistent with the goals and well-being of users. We can make ethical design decisions, taking into account how the human mind can be used, consider what we should and should not design, and talk to users to get quality feedback on how the products and experience we design affect on their lives. 3r33424.  3r33469. 3r33424.  3r33469. 3r33418.

3r33424.  3r33469. There are many useful resources that we can use to make our projects more intuitive for users. Here are a few that I refer to quite often:
