Maturation - 🧠ANSWER ✔✔Natural growth controlled by genes
Developmental Task - 🧠ANSWER ✔✔Specific task to master at certain ages
Critical Period - 🧠ANSWER ✔✔Important time when experiences greatly affect
growth
Influences on Growth & Development - 🧠ANSWER ✔✔Heredity, Environment,
Nutrition, Socioeconomic status, Health and Illness
