Final answer:
The most effective way for Victoria to get help is by using a personalized call for help or by directly addressing a specific bystander. These methods create a connection and reduce diffusion of responsibility, increasing the chance of getting assistance.
Step-by-step explanation:
The question pertains to the most effective way to attract attention and get help after Victoria has broken her leg. Among the given options, shout number 1, "Help! My name is Victoria and I've hurt myself. I need an ambulance!", and shout number 4, "You in the red vintage jogging suit, help me! I've hurt myself.", are most likely to yield the best response. This is because personalizing the request for help and specifically engaging with another person are known to increase the chances of eliciting a reaction from bystanders. This phenomenon relates to the 'bystander effect', where individuals are less likely to help a victim when other people are present. By personalizing the call for help (shout number 1), Victoria announces her name, which creates a personal connection and provides specific details about her situation. When she directly addresses a specific bystander (shout number 4), it reduces diffusion of responsibility, as the individual is singled out and may feel more compelled to act.
