[Date]
The life history is composite; where a prompt requires a real interviewee, the student's own interview and consent replace the composite events, which are bracketed where illustrative.
Introduction
A lifespan paper can try to apply every theory in the course to one life, or it can use one well. This paper uses Bronfenbrenner's ecological model, especially the chronosystem, the dimension of time and historical change, as its spine (Bronfenbrenner, 1979). Erikson's psychosocial stages mark where she stood at each point (Erikson, 1963). The life is composite: [Maria], born on São Miguel in the Azores, brought to New Bedford in [1967], a nursing assistant for thirty years, a mother of three and, in her sixties, the main caregiver for a grandson.
Infancy and Early Childhood
Summary: Maria was born in a farming village, the second of four children, and was cared for by her mother and grandmother in a household where three generations shared a house. She spoke only Portuguese. Analysis: Her first microsystem was large and stable, with several caregivers who were always present. In Erikson's first stages, trust and autonomy, this household offered the consistency that supports trust. The chronosystem was already moving, though: the island's economy offered little work, and a U.S. law passed in 1965 had reshaped immigration rules, allowing families to join relatives already in the United States. Her uncle in New Bedford would make the move possible. Events far beyond her village, in an exosystem she would never see, set her path.
Middle Childhood
Summary: At nine, Maria arrived in New Bedford. Within a year she spoke English better than either parent. She went with her father to the bank and with her mother to the doctor, explaining forms, letters and test results. She kept doing this until she left home. Analysis: Language brokering, children interpreting and translating for immigrant parents, is common in immigrant families, and research describes both costs and benefits: children may gain language skill, confidence and a sense of contribution, while some feel stress from adult responsibilities and from hearing information meant for adults (Morales & Hanson, 2005). For Maria, the mesosystem, the links between home and the outside world, ran through her.
At ten, Maria was the link between her family and every institution in the city; the mesosystem was not a diagram for her, it was her job. In Erikson's terms, middle childhood is the stage of industry versus inferiority, when children gain a sense of competence by doing work others value. Maria's competence was real and recognized by her parents, but it was also unusual: she was doing adult work. Her sense of industry may have been strengthened by it, even as some ordinary childhood work, play with peers after school, was pushed aside.
Adolescence
Summary: In high school Maria felt Portuguese at home and American at school. Her parents expected her to marry young and stay near the family; her teachers encouraged college. She worked at a garment factory after school. Analysis: Marcia described four identity statuses based on whether a person has explored options and whether they have committed: diffusion, foreclosure, moratorium and achievement (Marcia, 1966). Maria spent her teens in something like moratorium across two cultures, exploring which parts of each she would keep. The chronosystem pressed here too: the garment and fishing industries that employed her community were beginning to decline in the 1970s, which narrowed the paths her parents imagined for her. Her identity was built not by choosing one culture but by deciding, piece by piece, what each would mean in her life.
Adulthood
Summary: Maria married at twenty, had three children by thirty and worked for thirty years as a nursing assistant at a local hospital, where she often interpreted for Portuguese-speaking patients. Analysis: Erikson's stages of intimacy and generativity frame these years. Her work brought her childhood skill into adult life: as she had once interpreted for her parents, she now interpreted for patients and their families, often older immigrants like her parents. In Erikson's sense, this was generativity, care for others that extended beyond her family. In ecological terms, her work placed her once more in the mesosystem, as the link between a hospital and a community.
Later Life
Summary: In her sixties, Maria became the main caregiver for her grandson after her daughter's divorce, while her own mother, now in her nineties, moved in with her. Analysis: Erikson's final stage, integrity versus despair, asks whether a person can look back on life as meaningful. Maria's later years are not yet a time of looking back; she is caring for a child and a parent at once. Her generativity now reaches across two generations, and her ecological system has come full circle: a three-generation household, like the one she was born into, in a country she arrived in at nine.
What a Different Theory Would Show
An attachment lens would read her life differently. It would focus on the grandmother who shared her care in infancy and the loss of that daily presence at nine, and might ask how that separation shaped the way she later cared for her own grandson. That reading is possible, and it would add depth to the later sections. It would say less, though, about the institutions and historical changes that run through every stage of her life, which is why the chronosystem serves better as the spine here and attachment appears only as a question.
Threads and Breaks
The thread is clear: from childhood to her sixties, Maria stood between people who could not understand each other, first her parents and the city, then patients and the hospital, now her grandson and her mother. The breaks are clear too: the move at nine, the decline of the industries her parents knew and the change in her daughter's family each reshaped the systems around her. Bronfenbrenner's chronosystem explains both, because it shows how a life is shaped by when it happens as well as where.
Conclusion
Reading Maria's life with one theory as its spine shows something a stage-by-stage list would miss: the same skill and role appearing again and again in new forms. Erikson's stages help name where she stood at each point, but the chronosystem explains why her life took the shape it did. For a nurse, the lesson is practical: the patient in her sixties who interprets for an older relative may have been doing that work since she was ten.

What the NU145 Unit 10 assignment asks for
The final NU145 paper usually asks students to trace one person's development across the lifespan, using a real interviewee or a composite life history, and to analyze each period with course theories. Prompts commonly want five or more life stages, a summary of events at each, analysis using named theories and a conclusion about continuity and change. Instructors look for one theory used well across the whole life rather than many theories mentioned briefly, events linked to historical context and threads traced from stage to stage. Where a real person is interviewed, consent and privacy rules apply. Papers typically run eight to ten pages in APA style, with original theorists and research cited.
Inside the NU145 Unit 10 example
The paper opens with an introduction that chooses the chronosystem as its spine. Each life stage has a short summary of events, then analysis. Infancy places her first household within a changing exosystem. Middle childhood carries language brokering, weighs its costs and gains from an integrative review and reads her work through industry, with a highlighted line on the mesosystem. Adolescence uses Marcia's statuses for identity across two cultures. Adulthood shows the childhood role returning at the hospital. Later life finds a three-generation household again. A section asks what attachment theory would add, and the conclusion names threads and breaks and offers a lesson for nursing practice.
Where the points sit in the NU145 Unit 10 rubric
Final lifespan paper rubrics in NU 145 tend to award points for coverage of life stages, accurate use of theory, integration of historical and social context, continuity across stages, critical reflection and APA writing. Coverage points depend on each stage having both events and analysis. Theory points reward correct terms from Bronfenbrenner, Erikson and Marcia applied to specific events. Context points go to linking a life to its time, such as immigration law and local industry. Continuity points are earned by tracing a theme across stages. Reflection points require considering another theoretical reading. Writing points cover structure, headings and a reference list matching the citations. Using one theory well throughout usually earns more than using many briefly.
Common NU145 Unit 10 mistakes, and how to avoid them
Final lifespan papers often lose points by listing every theory from the course and applying each for a sentence. Another common weakness is summarizing events at each stage without analyzing them. Some students treat each stage as separate and never show how one shaped the next. Others leave out historical context, even though when a life happens shapes it as much as where. Choose one theory as the spine, give each stage events and analysis, connect stages with a clear thread, place the life in its historical moment and consider what a different theory would show. If you interview a real person, follow your program's consent rules and keep identifying details out.

Final papers here follow an interviewee, a public figure or the writer's own life, as each section chooses. Earlier unit work is welcome beside the final assignment's instructions and grading criteria, since the model reads one composite life across the course's stages with a single theory as its spine. The first custom sample is free, returned in 24-48h. The paper above is an original model document written by our desk, not a submitted student paper and not an official Purdue University Global document.

NU145 Unit 10 questions, answered
Where can I find a free NU145 Unit 10 sample paper?
The full NU145 Unit 10 final lifespan paper is here, following a composite immigrant woman from infancy to her sixties with Bronfenbrenner's chronosystem as the spine, Erikson's stages and four sources. We can help you plan the structure for your own life history.
What is the chronosystem?
Bronfenbrenner's term for the dimension of time in development, including historical change and the timing of life events, such as a move or an economic shift.
What is language brokering?
Children interpreting and translating for immigrant parents in settings such as banks, schools and clinics. Research describes both benefits and stresses for the child.
How many theories should the NU145 Unit 10 paper use?
One theory used well across the whole life gives the paper a clear spine. Others, such as Erikson's stages, can mark points along the way.
Can the final paper use a composite person?
Many prompts allow a composite life history or ask for a real interviewee. If you interview someone, follow the consent and privacy rules your course sets.
