developmental-psychology
Lifespan development from prenatal through aging. Covers Piaget's stages of cognitive development (sensorimotor, preoperational, concrete operational, formal operational), Erikson's psychosocial stages, attachment theory (Bowlby, Ainsworth, secure/avoidant/anxious/disorganized), moral development (Kohlberg, Gilligan), language acquisition (critical period, LAD, stages), adolescent identity formation, adult development, and aging. Use when analyzing how cognitive, social, emotional, and moral capacities develop and change across the human lifespan.

# Developmental Psychology Developmental psychology studies how people grow, change, and maintain stability across the lifespan -- from conception to death. The field addresses cognitive, social, emotional, moral, and physical development, asking not just *what* changes but *why* and *how*. The central tension is between nature (genetic endowment, maturation) and nurture (environment, experience, culture), with modern developmental science treating the interaction between them as the fundamental unit of analysis. **Agent affinity:** piaget (cognitive development, stages), vygotsky (social/cultural development, scaffolding) **Concept IDs:** psych-developmental-stages, psych-attachment-theory, psych-language-development, psych-adolescent-development ## Developmental Domains at a Glance | # | Domain | Key Question | Major Theorists | |---|---|---|---| | 1 | Cognitive development | How does thinking change with age? | Piaget, Vygotsky, information processing theorists | | 2 | Attachment | How do early bonds shape later relationships? | Bowlby, Ainsworth, Main | | 3 | Moral development | How does moral reasoning mature? | Kohlberg, Gilligan, Turiel | | 4 | Language development | How do

What does the developmental-psychology skill do?
Lifespan development from prenatal through aging. Covers Piaget's stages of cognitive development (sensorimotor, preoperational, concrete operational, formal operational), Erikson's psychosocial stages, attachment theory (Bowlby, Ainsworth, secure/avoidant/anxious/disorganized), moral development (Kohlberg, Gilligan), language acquisition (critical period, LAD, stages), adolescent identity formation, adult development, and aging.

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill developmental-psychology --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
