PSYC3210: Human Lifespan Development

A survey of physical, cognitive, emotional and social development from conception through late adulthood, with theory and research.

Updated October 2026 · 5 min read

PSYC3210 surveys physical, cognitive, emotional and social development across the lifespan, as seen in classical and contemporary research and theory.

The course asks you to apply stage and non-stage theories to modern problems and individual experiences. Students often find the theory vocabulary heavy and struggle to connect it to a concrete case.

Key Concepts Explained

Stage Versus Non-Stage Theories

Stage theories describe distinct phases people move through. Non-stage theories describe gradual, continuous change influenced by context.

Illustration (invented case): A teenager takes on a part-time job and starts questioning family rules. A stage theory might place this within a stage of identity formation. A non-stage view might stress how this job, peers and school gradually change the teenager's choices. Comparing them shows what each can and cannot explain.

Research Designs

Longitudinal studies follow the same people over time; cross-sectional studies compare different ages at once. Each has strengths and weaknesses worth naming.

Typical Assignments and How to Approach Them

A Lifespan Map for Revision

Organize your notes by age period, covering the physical, cognitive, emotional and social domains the catalog names.

PeriodBody and mindFeelings and relationships
ChildhoodGrowth, language, thinkingAttachment, peers
AdolescencePuberty, abstract reasoningIdentity
AdulthoodHealth, expertiseWork, partnership, family
Late adulthoodAging, stable knowledgeMeaning, relationships

Fill the cells from your course readings, since emphasis varies, and add the theorist and study that relate to each cell.

Worked Example: Comparing Two Theories on One Situation

Illustration (invented case): An adult changes careers at forty-five. A stage view may link this to a midlife period of reassessment. A non-stage view may point to economic change, new opportunities and gradual shifts in values. A strong answer weighs the evidence for each and states which explains this case more convincingly, noting that people differ.

Terms to Know

AttachmentAn emotional bond, usually between infant and caregiver
Longitudinal designFollowing the same people over time
