1- aquisition of knowledge:

Data acquisition is the process of absorbing and storing new information, the success of which is often measured by how well the information can be recalled later (back in memory). The process of storing and obtaining information depends largely on the representation and organization of information. In addition, the use of information can also be influenced by the way information is structured. For example, the bus schedule can be represented in the form of a map or timeline. On the other hand, the timetable provides quick and easy access to the arrival of each bus, but it does little to locate a particular stop. On the other hand, the map provides a detailed description of the location of each bus stop, but it cannot be easily linked to bus schedules. Both methods of representation are useful, but it is important to choose the right presentation for the work being done. Similarly, access to information can be improved by considering the purpose and function of the information you seek.
which often combines concepts like SCALPEL and CRUST.

Mental entertainment, or activation, automatically spreads from one concept to another. For example, thinking about BREAD expands the activation of related concepts, such as BUTTER and CRUST. These ideas are recommended, and thus easily recognizable or available in memory. For example, in a study by David Meyer and Roger Schvaneveldt of 1976 (a common semantic priming study), a series of words (e.g., BUTTER) and non-words (e.g. BOTTOR) were introduced, and participants prevented me from determining if each item was a word. A word appears very quickly when it follows a word related to a concept. For example, BUTTER is better known as a name when BREAD precedes it, rather than NURSE. This result supports the assumption that se related concepts are more strongly connected than unrelated concepts.

Network models represent more than just simple connections. They must represent ideas and complex relationships that contain information and understanding. For example, the concept of "Doctor using a scalpel" can be represented as a USE (DOCTOR, SCALPEL) proposal, which contains the DOCTOR and SCALPEL nodes and the USE link (see Figure 2). The teachers successfully used the same drawings, called mind maps, connections and key relationships and symbols between the main ideas of the lesson.

There are many types of information, but the most important difference is between the information advertising and the implementation process. Advertising knowledge refers to a person's memory of ideas, facts, or episodes, while process information means the ability to perform a variety of tasks. Knowledge of how to drive a car, solves a problem of repetition, or throwing a ball is all kinds of process information, called processes or performance. Process information may start out as disclosure information, but is processed. For example, when you first learn to drive a car, you may be told to "put the key in the fire to start the car," which is a descriptive statement. However, after launching the car several times, the action is automatic and is completed with little thought. Indeed, process information is often automatically available and requires little attention. It’s also much more durable (not easy to forget) than advertising information.

2- perceived performance :

CSS Dev Conf, Eli Fitch suggested how people tend to see time in different ways and that, in fact, people are able to exceed waiting times, especially at rest, by up to 36%. What does this mean?
In short, when a user hits the "Buy Now" button every passing moment feels like three seconds for the average user. Psychologically the human brain has a serious problem with the tolerance and delay of pleasure, which, of course, increases any entry of conflict and pain points. This, in turn, increases the levels of stress for your customers.
While it pays to have a codebase with 100% test results, very well-integrated integration with the build process, ready-to-post performance, all of this is something none of your users care about at the end of the day. The caveat is that all those “behind the scenes” development processes should be implemented and improved, but let’s not forget the User Experience. Even if your site is statistically efficient, the actual measure you have to turn to the visible performance of users.
Eli Fitch proposes to make the “idle phase a little more painful” or, in his own words, a “less waiting period”. Among his proposed action items is to prevent the user from feeling uncomfortable, which I especially like to give the user a "sense of confidence".
A study by Carnegie Mellon of Chris Harrison, Zhiquan Yeo and Scott E. Hudson states that the progress bar makes the user feel that time passes 12% faster and, more importantly, the effect of apparent speed increases as the waiting time lasts longer. Visual enhancements such as progress bars give the impression that something is happening to the user.
As an added benefit, having these visual cues will prevent the user from hitting the button several times, saving the network trips of each event canceled and restarted. Also, it can reduce the power of having a "ghost transaction" in the database, from improper posting of double commenting to the most serious problem of buying a product over and over again.
At times, you may be wondering if the spinner should do the trick, and justice, in fact, helps, however, spinners tend to take care of your user for a very short time. Fitch recommends "cheating", and expand your spinner with additional viewing lines to keep your audience engaged. You can create a spinner that randomly changes the layout, provides insignificant text for the user to read while waiting, and changes the layout slightly.

3- personal effectiveness :

Human efficiency is a global need. Having practical life skills can lead to more control over daily life, more focus and a sense of accomplishment. Those who are successful think that they have the power to control it and to control it. They are better prepared to face the unexpected and are more likely to face stress and confidence in their own strengths and abilities.
Self-employment is defined in relation to general skills that are important in dealing with various situations at work and in personal life. Everyone who studies Personal Effectiveness will develop skills related to success, goals and self-confidence.
Improving personal performance is an opportunity for self-reflection and exploration. Self-employment requires the level of commitment required to faithfully approach new learning that leads to change in individual performance.

The combination of skills that help us to live successfully, behave, build relationships and build the environment we are in, can vary from person to person. Some of them we have already developed at an early age and some are still in need of work because of the health conditions we have experienced. However personal skills can be developed by everyone for better health.
With Positive Success Group you can develop the following skills to work effectively

Time Management vs Power Management
Communication Skills Training
Verification Training Workshop
Goal Setting and Planning
Managing Workplace Change
Introduction to Coaching
The purpose of these workshops is to learn and develop oneself. They provide an energetic, short (3-hour) evening course that gives participants everything they need to build a self-improvement program. With this new approach and perspective, each participant can explore their new learning in everyday life and benefit from improvement.

For eg. While efficiency means how well something is done, efficiency refers to how useful something is. For example, a car is a very efficient means of transportation, which can transport people over long distances, to certain destinations, but the car may not be able to properly capture people because of its fuel consumption.
