According to commonly taught developmental theory, which is the primary psychosocial task of infancy (approximately birth to 1 year)?

Commonly taught developmental theory (such as Erikson's stages) identifies the primary psychosocial task of infancy (approximately birth to 1 year) as developing trust versus mistrust — the infant learns to trust caregivers when their basic needs are met consistently and lovingly. Identity formation is the task of adolescence, generativity belongs to middle adulthood, and career achievement is an adult concern. Understanding broad psychosocial developmental tasks by stage supports anticipatory guidance and family teaching. Recognizing the developmental focus of each life stage at a high level is a standard growth-and-development concept. (This reflects widely taught theory; verify against current NCLEX prep materials.)
