with high potential danger, participants confronted with an emergency alone or in the presence of another person were similarly likely to help the victim. This suggests that in situations of greater seriousness, it is more likely that people will interpret the situation as one in which help is needed and will be more likely to intervene. Degree of responsibility: Darley and Latané determined that the degree of responsibility a bystander feels is dependent on three things: Whether or not they feel the person is deserving of help The competence of the bystander The relationship between the bystander and the victim Forms of assistance: There are two categories of assistance as defined by Latané and Darley: Direct intervention: directly assisting the victim Detour intervention. Detour intervention refers to reporting an emergency to the authorities (i.e. the police, fire department) Implementation: After going through steps 1–4, the bystander must implement the action of choice. In one study done by Abraham S. Ross, the effects of increased responsibility on bystander intervention were studied by increasing the presence of children. This study was based on the reaction of 36 male undergraduates presented with emergency situations. The prediction was that the intervention would be at its peak due to presence of children around those 36 male undergraduate participants. This was experimented and showed that the prediction was not supported, and was concluded as "the type of study did not result in significant differences in intervention." A meta-analysis (2011) of the bystander effect reported that "The bystander effect was attenuated when situations were perceived as dangerous (compared with non-dangerous), perpetrators were present (compared with non-present), and the costs of intervention were physical (compared with non-physical). This pattern of findings is consistent with the arousal-cost-reward model, which proposes that dangerous emergencies are recognized faster and more clearly as real emergencies, thereby inducing higher levels of arousal and hence more helping." They also "identified situations where bystanders provide welcome physical support for the potentially intervening individual and thus reduce the bystander effect, such as when the bystanders were exclusively male, when they were naive rather than passive confederates or only virtually present persons, and when the bystanders were not strangers." An alternative explanation has been proposed by Stanley Milgram, who hypothesized that the bystanders' callous behavior was caused by the strategies they had adopted in daily life to cope with information overload. This idea has been supported to
