Russian Railways reaction test. Professional important qualities: reaction time. How to increase your reaction speed
Determination of reaction speed
Is there anyone who has not heard the phrase “response speed”? How many times have we “saved” mugs and plates at the last moment? How many times has she determined the result of competitions, relay races and competitions? Unexpected things can happen to any person, both at home and on the street, at any moment, and then
his health will directly depend on the speed of his reaction. But it is required not only for ordinary life. This is a professionally important quality for astronauts, pilots, sailors, military personnel, athletes, drivers, and operators. Hundreds of professions, thousands of situations, every day.
Probably, many people want to know the speed of their reaction or get an answer to the question: “Will I be able to catch up with Schumacher?” Will I be able to become a pilot or just increase my reaction speed a little?
What needs to be done for this?
First you need to measure it. It is not difficult to guess that the speed or speed of a reaction is measured by time, more precisely, by the time of a simple conditioned reflex reaction .
It is measured using complex instruments - chronoreflexometers,
and very simple and accessible means, for example, a school ruler. By the way, no less accurate.
Remember... everything ingenious is simple.
Measuring a simple conditioned reflex response
A simple conditioned reflex reaction is carried out as a simple movement in response to a simple signal. The signal-movement relationship is set by instructions spoken by the laboratory assistant.
Instructions
“You are offered a test of measuring reaction time using a school ruler. Need to catch her
in free fall.
The measurement is taken while standing. Keep your leading hand (right hand for right-handers) at chest level. Big
and the index finger must be brought as close as possible, but not touch the surface of the ruler. The zero mark should be located at the level of the upper edge of the index finger. As soon as you see the ruler falling, you should grab it. No additional command will be issued.
The measurement is carried out 3 times. Are you ready? Be careful."
Procedure
The measurement is carried out by two people. The readings are taken at the upper border of the index finger.
Interpretation of measurement results
After the measurement, the arithmetic mean of the three measurements is calculated and compared with the norms.

What is the limitation on human reaction speed?
The speed of a person’s reaction is determined by the functioning of the nervous system. When a person reacts to a very strong irritation that is life-threatening, for example, when he withdraws his hand from a hot object -
a simple reflex comes into play, in which the brain does not take part. Signal from the receptor
along the nerve fiber it goes to the spinal cord and then directly to the muscle, passing through only three nerve cells - a sensory neuron, an interneuron in the spinal cord and a motor neuron. The speed of the nerve impulse along the processes of nerve cells here is several tens of meters/sec. The determining factor is the time of synaptic transmission - about 0.1 sec.
First, the person withdraws his hand, and then feels pain. This is due to the fact that from pain receptors in
The brain signal travels along a different type of nerve fiber at a lower speed.
If we are talking about a person’s reaction to a stone flying at him, then there is also a reflex reaction: the eye transmits a signal about rapid movement not only to the parts of the brain where they are processed (and we understand: “a stone is flying”), but also through special nerves paths - to the muscles, which provides a quick avoidance reaction - moving to the side, jumping away, etc.
If we are talking about reaction when playing tennis, then a gradual improvement in reaction is associated with the formation of stereotypical reflexes that allow one to react without the participation of the cerebral cortex (without thinking), and, most importantly, such reactions are carried out without feedback, that is, there is no constant adjustment of movement . And when we are just learning to make a new movement, a complex interaction occurs: a signal about the action is sent to the muscle, a signal about the result of the action is sent back from it,
and an adjustment is underway, i.e. the muscle moves under constant control, which takes a lot of time.
All these processes involve different areas of the cerebellum and some other brain structures.
How to increase your reaction speed
The speed of human reaction can be increased. You can learn to respond to stimuli that precede an action. For example, not for a boxer’s blow, but for preparing for it - after all, before
hit the enemy will definitely look at the target, change his position, tense his muscles, inhale... There is more than enough time. You just need to develop a conditioned reflex, plant a new stimulus in the subconscious
and the response to it.
This exercise can help you with this:
Game of firecrackers.
The first partner stands and positions his open palm so that it is convenient for the second to hit it. For example, he stands sideways to the second person, holding his open palm in front of him. The second partner hits
palms of the first at arbitrary times. The task of the first is to remove the palm, the task of the second is to hit. You can keep score. Then the partners change. The principle inherent in this game can be transferred to other technical actions, for example, cutting and avoiding kicks at the lower level.
It is known that the subconscious reaction associated with the right hemisphere of the brain is much faster than the conscious reaction associated with the left hemisphere. It is logical to assume that it is in the subconscious that the
responses to a specific stimulus may be predetermined. And this is achieved through repeated repetition of movements during training. In total, you need to score about 5-10 thousand repetitions, and it makes no sense to do more than 300 repetitions at a time. 300 is a big enough number, it basically works out
no more than 200 movements per training, then it turns out that the subconscious assimilation of a motor pattern ideally requires about two months. Motor reactions must be carried out at the level of conditioned reflexes, and for this, as you can see, serious training is necessary.
You are invited to take the online reaction test “Red Square”; this or similar tests are used in the Central Operations Center of the Ministry of Internal Affairs to diagnose candidates for police service.
The “Red Square” test, in addition to reaction speed, acts as a test of genius, because To pass this test online, you need not only your reaction, but also a high level of intelligence.
In the Center for the Study of the Ministry of Internal Affairs, other tests and methods of psychodiagnostics are used: Polygraph, SMIL 566 questions, CAT test 50 questions, testing for associative thinking (proverbs and sayings are used), and also this (or a similar) test for reaction and genius online - Red Square.
How to pass the reaction and genius test Red Square online
To take the online reaction test, you need to move your mouse over the red square, and when you are ready, press the left mouse button, and while holding it down, move the red square so as not to collide with the blue figures and not touch the boundaries of the large square.
Ideally, to pass the genius and reaction speed test, you should hold for at least 18 seconds. You will see your test completion time in the training game window.
This or similar reaction tests and genius tests, like the “Red Square”, are taken by military pilots. In particular, in the USA, pilots hold the red square for more than 2 minutes, despite the fact that their IQ (intelligence quotient) is not lower than 140
So, take the online reaction and genius test “Red Square”
This testing can be used as a simulator to improve your reaction and genius.
(It is better to take testing on a computer using a mouse, because touch screens react more slowly to touching the Red square, which will not allow you to adequately pass the test of your reaction speed and genius).
Hover your mouse over the red square and start testing

Here is a selection of 10 tests to test various different types of memory, reaction speed, concentration, mental flexibility, spatial imagination and abstract thinking. They should be completed from a computer in a calm environment.
If some test is too difficult, then you should think about becoming a little more attentive to your health (drink 10 cups of coffee a day instead of 20, start sleeping at least 5 hours, eat at least 2 times a day) and take the time to practice this skill.
And if you showed a brilliant result in some test, then this is another reason to be proud of yourself and thank your parents for good heredity. For passing everyone The tests in the article will take no more than 15-20 minutes.
1. Visual memory
Pictures flash alternately on the screen. The faster you realize that you have already seen some picture and press the spacebar, the more points you will get. At the end, you will receive a verdict on whether your visual memory corresponds to the norm.
2. Reaction speed
Click on the test screen as quickly as possible if you see green. For men under 35, the normal reaction speed does not exceed 0.2 seconds. But if it is less than 0.4, then you don’t have to worry about your health and everything is OK. It is better to take this test using a mouse.
3. Memory for numbers
It's no coincidence that phone numbers have seven digits, as this is the maximum convenient number for most people to remember. If you were able to remember (within a limited time) a 14-digit number, you can be proud of yourself. And if you fail at 4-5, then perhaps you have some problems and you should repeat the test at another time.
4. Memory for words
Look at the word that appears on the screen and remember whether it was shown to you or not. The test is very short and at the end you will find out what percentage of those who passed the test remember the words worse than you.
5. Memory for faces
Facial recognition test from psychologists at the University of Cambridge. Boring and quite long (several minutes). I thought that I wouldn’t recognize people after changing my hairstyle/clothes due to poor eyesight, but it turned out that there really are some problems with facial recognition.
6. Spatial imagination
Look at the picture on the left and determine whether it would match the picture on the right if flipped at an angle. If you scored more than 100 points, then everything is fine with you.
7. Abstract thinking
A simplified version of the tag games familiar from childhood. Here you need to score at least 20 points.
8. Focus
If you manage to highlight more than 30 words in 2 minutes, then your result is already above average. The maximum result is 70 words.
9. Flexibility
Look at the text and determine what color it is written in. Press the first letter of the name of this color on the keyboard. Follow the link go to stats You can see the results of other test participants.
10. Speed
In 5 minutes you need to answer 41 simple questions (multiply two numbers, continue a number series, determine whether a word corresponds to a picture). If you scored more than 70% correct answers, you are a normal person.

At the end of many tests there is an opportunity to compare yourself with others. You can also post your results in the comments and discuss them with other iPhones readers.
But don't take the results too seriously. Firstly, even if, for example, your visual memory suddenly deteriorates significantly, this may well not interfere with your ability to cope with your work responsibilities and may not have any impact on your relationships with people.
And secondly, the result is influenced by the amount of sleep, mood, day of the cycle, blood alcohol, fatigue and other temporary factors. Tomorrow you can take the same tests with a completely different result.
Every day of our lives we react to some events. Most of these events do not require a quick reaction, but some, such as a cup falling from a table, the keys to an apartment that someone unexpectedly throws at you, or a fist flying at your forehead, require an immediate and quick reaction. Or in games, when an enemy suddenly jumps out from around a corner. Many pundits, mainly political scientists, philosophers and other calmers of human herds, directly tell us “all people are equal”, so many of us are perplexed “how can this be! We came across each other at the same time! how could he kill me faster!?” But the point is that with moral and legal equality, biologically people are not equal. Differences in heredity, nutrition, environment, training, childhood hobbies, lifestyle - all this leaves its mark on such a simple thing as reaction speed. And, no, I'm not talking about ping now. I’m now talking about the time that you, a human gamer, need to react to something.Due to the introduction of the thought “all people are equal” and “I’m no worse than this retard” into the brain, gamers simply forget that in addition to ping, lags, computer performance, mouse/keyboard glitches, monitor response time and finally the buggy nature of the game itself, there is also the player himself. And that his biomechanics can also slow down.
Scheme
The scheme is like this:- an action occurred (the enemy jumped out from around the corner);
- the image appeared on the retina (silhouette of the enemy);
- the image was transmitted through the optic nerves to the brain for recognition;
- the brain analyzes the image, recognizes it (yes, this is the silhouette of the enemy!), makes a decision on action (kill the reptile!);
- from the brain, a command is transmitted through the nerves to the muscles of the arm (contract! FAST!!);
- the arm muscles contract, the finger presses the button;
Statistics
The average reaction time varies - it is one for auditory stimuli, another for visual stimuli, but on average, this number tends to 200 milliseconds. We don't notice it because we live with it every day. Even what you see now is, in fact, a snapshot of the past about 0.1s ago (the eye took it and transmitted it along the nerve -> the brain recognized -> the brain realized). We get used to this reaction time and expect it, considering it normal. Some deviations are so small for us that we don’t notice them - like hundredths of seconds, if now we measure everything in minutes and hours. But in Action games, these very hundredths of a fraction separate victory from defeat.Some are faster, up to 110ms; these guys are among the top players in shooters and other Action games. This also includes professional starkcrafters with their insane speed of action.
It’s by looking at their video that our jaws drop and we begin to do the same as they do. Actually, this is their innate and honed talent, there is nothing to be surprised at. Some people draw amazingly, some fly planes cooler than birds can fly, and some know how to chop down everyone in games.
The other extreme is people with slow reactions. Most often they worry too much about something: “Someone came around the corner. What if it’s yours? No, it doesn’t look like it... What if it’s an enemy? Damn, where should you aim to hit it?” This can be fixed - throw unnecessary thoughts out of your head and concentrate. But sometimes this is caused by the biochemistry of the nervous tissue, which cannot quickly transmit a signal from the eye to the brain and from the brain to the muscles of the hand. Usually such people are constantly killed in shooters, they don’t like it and they abandon them. Or they switch to games of a different genre - turn-based strategies, card games or any others where a 200ms difference in reaction is not decisive. Only the most stubborn remain.
Each of us has a speed limit, for some it is lower, for others it is higher. And a person physically cannot accelerate faster than his “biological ping”. Little is written about this because it is not particularly positive, but this is our reality. As they say, “Deal with it!”
To all those who suffer from delayed reactions
Why am I describing all this in such detail? Because my reaction time is 260 milliseconds. That is, in shooters where you need to shoot FAST and accurately, I will be somewhere at the bottom of the list. I know this and that’s why I don’t try to beat the lightning people according to their rules. It's like racing with a cheetah - sad and uninteresting. I abandoned Quake and other UBER-dynamic action games because there was simply nothing for me to do there and switched to others that had more tactical options. But everywhere, in any action, a reaction will take place! The only thing I can do to compensate for this is to deeply understand the mechanics of the game, predict the actions of the enemy and do what is not expected of me. The fact is that the body’s “ping” is lower if it expects some action - the brain has already thought through what commands need to be given and is ready to execute. And the more such “blanks”, the better.Naturally, if I encounter the same cunning opponent, only with better biochemistry of nervous tissue, I will lose. But there are few of them and they are usually somewhere high at the top of the gaming Olympus. But I’m not eager to go there! =) I don’t care about achievements, medals, ratings, ladders and other indicators of a player’s overall strength in a particular discipline. I don’t want to become a player in one of the professional e-sports teams - I physically cannot become one and I know it. I just want to enjoy a good game. And if you manage to kick the butt of a couple of noobs who rely only on their innate reaction and have not put in an ounce of effort to understand the game, the pleasure is tripled.
Therefore, if you have a reaction time at the level of mine and you want to become a professional player, for example in counter-strike, I have bad news for you. Be realistic, soberly assess your abilities and draw appropriate conclusions. For example, my girlfriend has a reaction time of 170 milliseconds, I tried to beat her at fists and lost with a shameful score. Well, that means I won’t play this crap! =)
Is it possible to develop a reaction?
Up to a certain limit - yes. You can optimize what depends on the brain - get rid of unnecessary garbage thoughts and try to predict the actions of the portico and think through your response actions. Think over “ways of improvisation”, create “patterns of behavior, etc.” In other words, understand the game deeply.In addition, your reaction is influenced by your well-being, fatigue, mood and other distractions. Reaction times may vary from day to day depending on these factors.
The next step is to improve the speed of neural tissue. But I’m not your advisor here - consult a doctor. In general, think about it - do you need it?
How and where can the response be measured?
It is measured simply - a person is waiting for some action and must press a button at the right moment. The difference between “action” and “pressing a button” is your reaction time, your “biological ping”. There are even special devices for measuring reaction time.But there are not so many sites on this topic. As I already said, the topic “X’s reaction will always be better than Y’s” is not particularly positive and is not popular among people with complexes.
Friends, there are 2 news - bad and good:
Bad: the speed of your reaction cannot be physiologically changed, it is innate.
Good: but the psychological conditions for the appearance of a reaction can be varied - and I’ll tell you how.
We will not write about the importance of reaction speed for a tracer - it is obvious.
Reaction speed is the time from the start of the signal to the body's response.
In Wundt's laboratory, the Russian psychologist Lange discovered the existence of two different types of reactions, which he called motor and sensory.
Sensory response is the time from the start of the signal to its perception (awareness), i.e. the subject's attention is directed to waiting for a signal.
Motor - time from the start of the signal to the completion of the response movement, i.e. attention is directed to the upcoming action.
Amazingly, the motor reaction is almost 2 times faster than the sensory reaction.
This is explained by the fact that the motor reaction is not a fully mental reaction, but only a brain reflex, since the action is already included in the “program” and, unlike the sensory one, there is no process of perception and volitional decision in it, only a reflex. This also happens because the spinal cord and medulla oblongata are responsible for the motor response - “a simpler but faster computer” compared to other parts of the brain.
A person’s reaction time depends on the modality of the stimulus - the type of stimulus signal, the intensity of the stimulus, training, the mood to perceive the signal, age and gender, and the complexity of the reaction.
For example, visual information is perceived most quickly. A normal person visually perceives 3-5 thousand characters per minute. With training, the speed of information perception increases. The Guinness Book of Records records text reading at a speed of 150 thousand characters per minute. Auditory information is perceived more slowly. The maximum perception speed ranges from 300 to 1000 characters per minute. Smells are the slowest to perceive. A person perceives one smell from several seconds to ten minutes.
So it’s good that when we fall, we will focus on the readings of tactile, visual and vestibular sensitivity, and not on the (possible) appearance of the specific smell of hydrogen sulfideJ.
For further consideration, we will describe 3 different situations:
1) When a person withdraws his hand from a hot object, a simple reflex comes into play, in which the brain does not take part. From the receptor, the signal travels along the nerve fiber to the spinal cord and then directly to the muscle, passing through only three nerve cells (yes, only 3): a sensory neuron, an interneuron in the spinal cord and a motor neuron. The speed of the nerve impulse along the processes of nerve cells here is several tens of meters/sec. The determining factor is the time of synaptic transmission - about 0.1 sec. First, the person withdraws his hand, and then feels pain.
2) If we are talking about a person’s reaction to a stone flying at him, then there is also a reflex reaction: the eye transmits a signal about rapid movement not only to the parts of the brain where they are processed (and we understand: “a stone is flying”), but also through special nerves paths - to the muscles, which provides a quick avoidance reaction - moving to the side, jumping away, etc.
3) If we are talking about the reaction when playing tennis, then the gradual improvement of the reaction is associated with the formation of stereotypical reflexes that allow you to react without the participation of the cerebral cortex (without thinking). And when we are just learning to make a new movement, a complex interaction occurs: a signal about the action is sent to the muscle, a signal about the result of the action comes back from it, and an adjustment occurs. All these processes involve different areas of the cerebellum and some other brain structures.
