Rites of Passage refer to the rituals, ceremonies, or life events that signify a person's transition from one stage of life to another. In the case of adolescence, these can be related to physical changes due to puberty, health, information processing during adolescence, and moral reasoning. Physical development during adolescence is mainly characterized by the growth spurt and puberty. The latter involves biological changes such as the maturation of sexual organs, development of secondary sexual characteristics like breasts in girls and facial hair in boys, and a dramatic increase in height and weight. Such changes usually begin around ages 10-14 for girls and 12-16 for boys. In terms of health, adolescence is a critical period due to increases in risky behaviors such as substance use, accidents, injuries, and sexual behaviors. However, it is also a time of significant resilience and opportunity for positive health behavior changes. Information processing during adolescence is also developing, wherein the adolescent starts to think more abstractly and critically. They become more capable of introspective thoughts, thinking about their own thinking, and understanding metaphorical or hypothetical concepts. Finally, reasoning about moral issues also changes during adolescence. Often, young adolescents tend to think in terms of black and white, right and wrong. As they mature, they start to comprehend shades of gray, understanding that moral issues can be complex and context-dependent. This is in line with the progression from conventional morality (adherence to rules and social order) to post-conventional morality (understanding of moral principles and the affirmation of agreed-upon rights). It's crucial to note that these changes can greatly vary from individual to individual, and may also be shaped by cultural, socioeconomic, and other contextual factors.
