Stages in a Police Officer's Professional Lifespan

Hello,
I need a little help starting this assignment.
I chose the following stages of the police professional lifespan I feel would benefit from interventions; Age 22-28, Age 28-33, & Age 40-45
Application: The Lifespan of the Police Professional
Over the course of a person's life, he or she develops and matures physiologically, emotionally, and cognitively—these changes have been the focus of many developmental psychologists. In the 1920s, Jean Piaget began to publish his theories regarding cognitive changes that occur from birth through adolescence. Shortly after, Erik Erikson began his study of social development in which he explained that conflicts must be successfully resolved at each stage before moving to the next. Lawrence Kohlberg followed with his work related to moral development reasoning stages, which progress into adulthood. In general, those who have studied the human lifespan agree that psychological, intellectual, and spiritual growth continue in the midst of environmental, cultural, and social influences. Throughout this process of human development, the individual may acclimate to, suffer from, or rise above challenges that surface.
Developmental stages also may be applied to careers. Dalton, Thompson, and Price (1977) described changes that can occur throughout a person's career based on an individual's thoughts, behaviors, and actions. They described these changes as indicative of distinct developmental stages. Fagan and Ayers (1982) applied the study of developmental stages to the area of police work. They discussed specific psychosocial stages that a police officer could go through and the importance of stress management skills for successful coping at these different stages. Understanding the stages of a police officer's career lifespan may assist the officer with successful transitions and choices throughout his or her career. This understanding also may help forensic psychology professionals recognize opportunities for beneficial intervention (e.g., support, training) during the police officer's lifespan.
To prepare for this assignment:
•Review the article, "The Life of a Police Officer: A Developmental Perspective." Focus on a police officer's stages of lifespan development. Consider how motivation relates to each stage. Also, think about types of interventions (e.g., training, support, counseling) that would benefit a police officer in each stage.
•Review the article, "Tough Cop—Soft Cop? The Impact of Motivations and Experiences on Police Officers' Approaches to the Public." Consider the impact of a police officer's motivations and experiences on his or her approaches to the public. Think about how motivation and experience influence and relate to police officer lifespan development.
•Review this week's media, "Developmental Lifespan Stages of Police Officers." Consider the police career lifespan as it relates to other stages of adult development. Think about the stages at which intervention would be most useful to a police officer and consider which interventions would be the most effective for each stage.
•Select three stages of the police professional lifespan in which interventions may be most useful to police officers.
•Think about one intervention you would use at each of these stages and consider why.
The assignment (1-3 pages):
•Identify and explain three stages of the police professional lifespan in which interventions (e.g., training, support, counseling) would be most useful.
•Describe one intervention that you would recommend for each stage and explain why you selected each.
•Support your responses with references to the Learning Resources and the research literature.
