During the sensorimotor stage (0-2 years), infants learn through their senses and physical interactions with the environment. They gradually develop basic concepts like object permanence through direct sensory and motor experience.
The concrete operational stage occurs from approximately 7 to 11 years of age. During this stage, children develop the ability to conserve, think logically about concrete events, and understand reversibility.
Accommodation is the process of modifying existing schemas or creating new ones to accommodate new information that doesn't fit existing schemas. This is how children's thinking evolves and becomes more sophisticated.
Assimilation is the process of taking in new information and fitting it into existing mental schemas. For example, calling all four-legged animals 'dogs' until the child learns to differentiate.
In the preoperational stage (2-7 years), children lack conservation ability—they cannot understand that quantity remains the same even when appearance changes. This is a hallmark feature of this developmental period.
Piaget defined schemas as cognitive structures or mental patterns that organize and guide our understanding of the world. They are fundamental units of knowledge that children build throughout development.
Vygotsky's sociocultural theory emphasizes that cognitive development is deeply rooted in social interactions and cultural contexts. Learning is mediated by cultural tools and interactions with others.
Trust vs. Mistrust is Erikson's first psychosocial stage, where infants develop basic trust in caregivers. Consistent, responsive care promotes a sense of trust and security.
In the Concrete Operational Stage (7-11 years), children develop the ability to understand conservation and perform reversible logical operations, but these are limited to concrete (tangible) objects.
Erikson identified Identity vs. Role Confusion as the primary psychosocial conflict during adolescence, where teenagers develop a sense of personal identity and independence.
