Unit 1 Human Lifespan Development Assignment Brief 2026 | Pearson

Unit 1 Human Lifespan Development Assignment Brief

Students will understand human growth and development across life stages, the factors influencing development, and the role of health and social care professionals in promoting wellbeing.

Unit introduction

Understanding how humans grow and develop across their lifespan is essential for anyone entering the health and social care sector. This unit explores the physical, intellectual, emotional and social changes that occur from infancy through to late adulthood,  helping you appreciate the complexity and uniqueness of individual development.

In this unit, you will learn how to explore the wide range of factors that influence development, including genetics, lifestyle choices, environmental conditions and social inequities. The unit also reflects modern issues such as digital health, mental wellbeing  and the evolving roles of health and social care professionals in promoting holistic care.

By completing this unit, you will build a strong foundation for further study or employment  in health and social care. You will develop transferable skills such as critical thinking, communication and empathy, which are essential for progression into higher education, apprenticeships or frontline care roles.

Learning Aim and Assessment Criteria

The essential content is set out under content areas. Students must cover all specified content before the assessment.

Learning aim A: Understand human growth and development across life stages

Students will explore holistic development. They will understand the relationship of the different areas of development and the effect they have on each other.

A1 Physical, intellectual, emotional and social development in infancy – (birth to 2 years)

A4 Physical, intellectual, emotional and social development in early adulthood  (19 to 45 years)

• Physical: physical maturity: physical strength peaks, fertility, brain growth until early twenties; pregnancy and lactation occur; synaptic pruning; perimenopause – oestrogen levels decrease, causing the ovaries to stop producing an egg each month.
• Intellectual: new intellectual skills develop relating to further/higher education and work.
• Emotional: long-term intimate relationships; changes to self-concept, including self-esteem and self-image related to lifestyle (work, family); bonding and attachment with own family/guardians.
• Social: independent from family, groups of friends.

A5 Physical, intellectual, emotional and social development in middle adulthood  (46 to 69)

• Physical: menopause, to include: hot flushes, night sweats, cessation of menstruation and vaginal dryness; start of physical strength declining, vision and hearing loss; changes related to lifestyle factors, to include: weight gain, joint pain related to wear and tear; men’s health awareness (e.g. andropause, prostate health) and mental health in midlife, including burnout and work-life balance.
• Intellectual: improvement in verbal and reasoning skills from applied learning.
• Emotional: re-evaluation of priorities; contributing to the next generation, sense of emptiness as children grow up; emotional factors relating to menopause including changes to mood and libido.
• Social: relationships with peers at work; more social lifestyle with no children/early retirement/retirement; limited social life due to work pressures; changing roles – becoming a grandparent.

A6 Physical, intellectual, emotional and social development in late adulthood (70+ years)

• Physical: lung capacity reduces, arteries and heart muscle thicken, brain cells lose some functioning, falls from reduced mobility.
• Intellectual: ability to learn new skills (though may take longer), short-term memory less easily recalled, wisdom and creativity remain.
• Emotional: calmer, feeling alone, feeling younger than age, feelings of frailty.
• Social: more opportunities to meet friends due to retirement, meeting new people as taking on new activities; reduction in social circle of peers through this life stage; digital inclusion for older adults, such as using technology to maintain social connections and access services.

Learning aim B: Examine factors affecting human growth and development
