The term bystander effect refers to the phenomenon in which the greater the number of people present, the less likely people are to help a person in distress. When an emergency situation occurs, observers are more likely to take action if there are few or no other witnesses. Being part of a large crowd makes it so no single person has to take responsibility for an action (or inaction).
The most frequently cited example of the bystander effect in introductory psychology textbooks is the brutal murder of a young woman named Catherine "Kitty" Genovese. On Friday, March 13, 1964, 28-year-old Genovese was returning home from work. As she approached her apartment entrance, she was attacked and stabbed by a man later identified as Winston Moseley.
Despite Genovese’s repeated calls for help, none of the dozen or so people in the nearby apartment building who heard her cries called police to report the incident. The attack first began at 3:20 AM, but it was not until 3:50 AM that someone first contacted police.
While Genovese's case has been subject to numerous misrepresentations and inaccuracies, there have been numerous other cases reported in recent years. The bystander effect can clearly have a powerful impact on the general conduct of people in a society, but why exactly does it happen? Why don't we help when we are part of a crowd?
There are several factors that contribute to the bystander effect. First, the presence of other people creates a diffusion of responsibility. Because there are other observers, individuals do not feel as much pressure to take action, since the responsibility to take action is thought to be shared among all of those present.
The second reason is the need to behave in correct and socially acceptable ways. When other observers fail to react, individuals often take this as a signal that a response is not needed or not appropriate. Other researchers have found that onlookers are less likely to intervene if the situation is ambiguous. In the case of Kitty Genovese, many of the 38 witnesses reported that they believed that they were witnessing a "lover's quarrel," and did not realize that the young woman was actually being murdered.
Characteristics of the situation can play a role. During a crisis, things are often chaotic and the situation is not always crystal clear. Onlookers might wonder exactly what is happening. During such chaotic moments, people often look to others in the group to determine what is appropriate. When people look at the crowd and see that no one else is reacting, it sends a signal that perhaps no action is needed.
So what can you do to avoid falling into this trap of inaction? Some psychologists suggest that simply being aware of this tendency is perhaps the greatest way to break the cycle. When faced with a situation that requires action, understanding how the bystander effect might be holding you back and consciously taking steps to overcome it can help. However, this does not mean you should place yourself in danger.
But what if you are the person in need of assistance? How can you inspire people to lend a hand? One often-recommended tactic is to single out one person from the crowd. Make eye contact and ask that individual specifically for help. By personalizing and individualizing your request, it becomes much harder for people to turn you down.

Things You Should Insist on No Matter What People Say
Life can get pretty crazy at times．Happiness is dependent upon ourselves，and there are some things in life you should always insist on doing，no matter what others have to say about it．Here is a list of some things you should always do．
1．Learn from your mistakes
No matter what people say，you will make mistakes in your life．Life is a learning process in itself．Some people will make you feel bad about your mistakes，or insult you for making them．Accept your mistakes fully and really figure out what went wrong．
2．Embrace change and creativity
A popular proverb is，“You cannot solve a problem in the same state of consciences that created it．” Change and creativity are vital in today’s world．Things are always changing，so why should we be any different?
3．Appreciate what you have
This can take away from our happiness．Sometimes you just need to sit back and be happy about where your life is right now，and what you have to show for it. Sure people might tell you it’s not good enough，but don’t listen to them．It is good enough，and it gives you a sense of pride when you can enjoy the things you already have in life．
4．Listen to your heart
Sometimes you just need to follow your instincts and do what your heart tells you. There are some situations，like relationships，that rely more on your heart than on your head．People will surely tell you differently，but you should always insist on listening to what you want and feel. Again，you are the one who lives with your choices，and you are the one that has to live with the“what ifs．”

“We see lots of adults being diagnosed as attention deficit hyperactivity disorder (ADHD) (多动症) around age 38,” says Timothy Widens, MD, an professor of psychiatry at Harvard Medical School. “That’s right around the time people start doing more-tasks, juggling jobs, families, a home, and other personal duties，” he says.
But not everyone who slacks on work or forgets appointments has ADHD; there are plenty of other reasons you may be losing attentions. Here are five things that could be sucking your attention span dry.
1. Technology overload
Your computer, cell phone, and iPod all compete for your attention—no wonder you're distracted(心烦意乱)! To a certain point, your brain can act as secretary, keeping you organized and helping with time management. But the more tasks you try to do, the harder it is for you to stay focused on any single task, research shows. Learning basic organizational skills, like writing down responsibilities and maintaining a day planner, can help reduce these problems. So take a break from constant television, Internet, and email floods
2. Lack of sleep
If you’re missing out on enough shut-eye—most likely seven to eight hours a night—you’re probably easy-angry, dealing with mind fog, and have difficulty addressing daily tasks. That’s a normal reaction, says Dr. Widens.
3. Poor job satisfaction
Sure, everyone’s unhappy at work from time to time—maybe your customer presentation failed or your boss gave you a poor performance review. And if a disorganized working environment or a boring project make it difficult to focus, that's completely normal. But if you find that you often can't complete projects，you probably need medical attention, or a new job.
4. Too much stress
Stress takes side affects on concentration. Researchers at the University of Madison found that the relaxation technique can add to your ability to focus on your mind. Another study, from researchers at UCLA, suggests that in adults with ADHD, meditation improves attention and eases symptoms of anxiety and depression.
5. Too little exercise
Mounting evidence suggests that regular exercise can keep your mind sharp and increase learning and memory ability. It’s even more important in adults with ADHD. ” My patients who exercise all report that they see improvement in attention,” says Dr. Widens. Working up a sweat can also help you burn off the extra energy that causes you to feel uncomfortable, and it can help you sleep better at night.
Hopefully after you understand these helpful methods, you become more attentive on what you are doing.
