Who were latane and darley ap® psychology bystander effect review.
If you witnessed an emergency, you would certainly help those in need, right? Even if you didn’t directly address the problem, if someone were in desperate need of help, you would definitely call the police or an ambulance at the very least, correct? Well, social psychology doesn’t think so. Based on Latane and Darley’s experiments on the bystander effect, your likelihood of helping a person in an emergency is highly dependent on the number of people around you at that moment. The bystander effect is an important social behavior from which we can learn a lot for periods of crisis, and it helps us understand human behavior for groups of people. Therefore, it is important to understand the bystander effect, its causes and possible counteractions for the Advanced Placement (AP) Psychology exam.
New York, March 13, 1964. A woman named Catherine Susan Genovese, commonly known as Kitty Genovese, is stabbed, robbed, sexually assaulted and murdered on the street by a man named Winston Moseley. The tragedy lasted for approximately thirty minutes, during which Kitty Genovese screamed for help. The lights on the nearby apartments went on and off, neighbors heard her screaming, watched from the windows and not one of the thirty-eight witnesses called the police.
If this were a scene from a thriller book, it would sound non-realistic. The editor of the book would probably look straight at the author and protest, “You can’t put a bunch of witnesses on a thirty-minute crime and have none of them lift a finger to help! No reader would believe this!”
This is why the murder of Kitty Genovese shocked the population in 1964. We like to think we are mostly good, ethical and altruistic individuals who would never refuse to help someone in an emergency. At the time, professors and preachers tried to explain this apparently horrifying indifference and lack of intervention with reasons such as “moral decay,” “alienation” and “dehumanization produced by the urban environment.” Social psychology researchers Bibb Latane and John Darley , however, had another hypothesis.
Their hypothesis was that when we are in the presence of other people, we are less likely to intervene in an emergency. Why? What happens? What’s so different between being alone and being in a group when a problem occurs? This is what Latane and Darley explored in their experiments on bystander effect, a critical discovery in the field of social psychology .
In 1968, Latane and Darley created a situation similar to that of Kitty Genovese’s (but without violence)to understand what social forces were acting on the day of the crime.
In the first experiment, Latane and Darley recruited college students to participate in what seemed to be an innocent talk with other college students. Each participant was given headphones and a microphone and stayed alone in a room, talking to other students through the intercom. According to the researchers, this was done to protect everyone’s anonymity. The theme of the conversation was college life problems, worries and the like.
Next, Latane and Darley divided the participants into three groups:
In a certain point of the conversation, a person in the intercom started acting as if he was having a seizure and asked for help. Latane and Darley wanted to investigate the difference of behavior between each group, according to the number of witnesses. These were the results:
“Well, okay,” you might say, “Maybe the number of people around you influences the likelihood of giving assistance, but if it were the participants’ own lives that were at risk, I’m sure everybody would do something regardless of the number of bystanders.”
Latane and Darley thought about that too and developed a second experiment to investigate this. How do you think that one went down?
For the second experiment, Latane and Darley once again recruited college students, this time to “fill out a questionnaire.” They divided the participants into two groups:
A few minutes after the participants start the task, a black smoke starts to creep out from the room’s air conditioner. It gets thicker and thicker until the room is filled with smoke. However, in the second group, the confederates were instructed to ignore the smoke, and so no one seems to be bothered about it. What do you think happened?
This is a surprising result that confirms the first study’s findings: the greater the number of bystanders, the less likely we are to act. Even if we ourselves could be in danger, being surrounded by people who do nothing makes us more likely also to do nothing. This opposes the intuitive idea that the more people there are in an emergency situation, the more likely it is that someone would call for help. As Latane and Darley have shown in their studies, it is quite the contrary.
As we have seen earlier, the bystander effect states that the likelihood of intervention is inversely related to the number of bystanders . In other words, the more witnesses there are, the less likely each one of them is to intervene in a problematic situation. But why does this happen? What can explain this?
The main reason proposed by Latane and Darley is diffused responsibility. When you are in a large group and something needs to be done, you feel less responsible for the task. There are so many people around; someone else is surely taking charge of the situation, so why should you step up? The sense of responsibility is diffused in the group, and the result is that, very frequently, no one does anything.
This is what happened in the Kitty Genovese situation. The thirty-eight neighbors witnessed the crime and saw each other through the windows. “Of course someone will call the police,” each one of them thought, “a woman is being murdered right on the street!” Unfortunately, diffused responsibility led to none of them taking action.
Another reason for the bystander effect pointed out by Latane and Darley is pluralistic ignorance . Pluralistic ignorance is what happens when you observe a situation and at first think that, for example, it is dangerous. However, people around act as if it isn’t a problem and don’t look concerned. Then, you also assume that it’s really not a big deal and that the right thing to do is just to keep doing what you’re doing and not intervene.
In the Kitty Genovese situation, the neighbors looked around to check how others were reacting, and since no one was getting desperate and fighting to help her (because of the diffused responsibility effect), they continued with their everyday lives despite her persistent cries for help.
According to Latane and Darley, bystanders go through a 5-step cognitive and behavioral process in emergency situations:
Latane and Darley’s crucial studies were further investigated by other social psychologists who continued to develop the knowledge on what makes us more likely to help others and show altruistic behavior. Some of the other variables are:
Okay, so now you know the dangers of the bystander effect and why and how it happens. You might be wondering: “Is there anything we can do to avoid it? How can we increase the likelihood of helping other people?”
Fortunately, there are possible measures to counter the bystander effect and avoid future Kitty Genovese situations. After all, this is the main reason to study human behavior: not to think of our tendencies in a conformed and cynical way and make the same mistakes over and over again, but to reflect on how we can improve ourselves, our lives and our relationships. So here are a few tips to use this knowledge in our service:
Now that you’ve learned all about Latane and Darley’s bystander effect, try to answer the following FRQ from a past exam:
For each of the following pairs of terms, explain how the placement or location of the first influences the process indicated by the second:
– Presence of other, performance
There are many possible answers to this question, for example social facilitation, social loafing, conformity and the theme of this AP® Psychology review : the bystander effect. Whatever you choose, the important thing is to correctly describe the phenomenon of choice and connect the elements “presence of other” and “performance” in a clear way.

The Smoky Room Experiment tested these intuitions by placing individuals in a fake emergency situation, and with different group dynamics. In all the experimental conditions, subjects were asked to complete a survey in a room that slowly filled with smoke. The smoke was, of course, harmless, but the subjects were unaware of this.
Smokey Room. In this experiment participants sat in a waiting room and filled out a questionnaire on life as a student. After completing two pages of the questionnaire, the room slowly filled with smoke that was puffed through an air vent. By the time the participant would have finished filling out the survey, visibility was impaired due to the ...

The real experiment occurred in the waiting room. As they filled out the forms, smoke began to enter the room through a small vent in the wall. By the end of four minutes, there was enough smoke to obscure vision and interfere with breathing. Darley and Latané examined how the students reacted to this smoke in two different conditions.

A late 19th-century view of the smoking room in a gentlemen's club. The three men at lower right are engaged in earnest discussion. In U.S. political jargon, a smoke-filled room (sometimes called a smoke-filled back room) is an exclusive, sometimes secret political gathering or round-table-style decision-making process. The phrase is generally used to suggest an inner circle of power brokers ...
Results. When participants were alone, 75% of them left the room to report the smoke. In the second condition, 10% of participants reported the smoke. The others coughed and waved the smoke away from their faces, but continued to fill out the questionnaire. In the third condition, 38% of the participants reported the smoke.
Genovese's death did launch the field of research into this concept. Perhaps the most famous example is the Smoke Filled Room study. In 1968, a pair of social psychology researchers, Bibb Latane and John Darley, set up a series of experiments searching for an explanation for cases like the Kitty Genovese murder.
What were the results? - Alone: 75% reported the smoke, taking 2 minutes on average. - Two passive confederates: 10% reported the smoke, coughing and rubbed their eyes but continued with the questionnaires. - Two real participants: 38% reported the smoke. - Post-experiment interviews revealed that the participants were unsure of the smoke's ...

As a part of the experiment, smoke began to fill the room. Three different conditions led to three different results. Experiment statistics showed that 75% of the alone participants reported the smoke to the experimenter. When there were two other participants, only 38% of the subjects reported the smoke.

And when the number of people in the room increased, the number plummeted; 38% reported when all people were participants, and only 10% did so when the participant was with 2 actors of the experiment.
15 The results of the famous smoke-filled room experiment by Latané and Darley (Citation 1968) were interpreted to suggest that others' non-responses indicated to participants that the smoke was not dangerous.However, Darley and Latané's (Citation 1968) parallel study, using a (less ambiguous) epileptic seizure as the emergency, led to the conclusion that diffusion of responsibility was ...
