2Summary Theoretical Basis of the Research ‘Wearing a Bicycle Helmet Can Increase Risk-Taking and Sensation Seeking in Adults’ isa study done by Tim Gamble and Ian Walker in 2016 which advances how human beings adopt risk-taking behavior when safety is almost certain. The study shows how people take increased risks when protective equipment is worn. It demonstrates that the risk-taking process is high when a person is not aware that a piece of protective equipment has been worn, especially for those behaviors that are not made safer by protective equipment. The study uses three theories to justify its findings: Risk Allostasis Theory (Lewis-Evans & Rothengatter, 2009), Risk Homeostasis Theory (Wilde, 1998), and Risk Compensation Theory (RCT) (Adams & Hillman, 2001). RCT states that individuals can adjust their behaviors in response to a certain level of risk perceived and become more cautious when they sense an elevated risk but are less vigilant if there is a sense of protection. Objectives The objectives of the study were to establish if wearing a bicycle helmet is a significant factor in increased sensation-seeking and risk-taking among adults. According to RCT, an individual reacts to safety regulation or law by being less cautious. Wearing helmets would reduce the risk to facial, brain, and head injuries for an individual if involved in a crash, hence wearing one makes one take a risk because of the safety measure provided by the protective equipment. Additionally, the behavior of the cyclist is influenced by wearing a helmet, this affects the probability of one being involved in an accident. Individuals wearing helmets are more likely to ride a bicycle less cautiously because they feel they are entitled to protection.
