Piaget Stages Sensorimotor Stage
Development happens from one stage to another through interaction with the environment. • Changes from stage to stage may occur abruptly and kids will differ in how long they are in each stage. Stages of Development
Age ranges are not rigid, although the sequence is invariant. Must go through them in the theoretical order • Overlap between stages can occur – known as décalage – e.g. 7 year old may show signs of 11 year old thinking “ahead of time” Stages of Development
Cognitive development can only happen after genetically controlled biological growth occurs. • Development leads to learning • The child can only learn certain things when she is at the right developmental stage. Stages of Development
Development through stages is motivated by equilibration. • Child has novel experience – disequilibrium • Internal schemas and operations reorganised via assimilation/accommodation • New equilibrium – move to next stage Stages of Development
Piaget’s theory of development includes four stages: • Sensorimotor • Pre-operational • Concrete Operational • Formal Operational Four Stages
Birth to about 2 years • The child knows the world through sensation and action • Actions are eventually internalised as thoughts The Sensorimotor Stage
From about 2 – 7 years • Understanding of the world through visual appearances and non-logical assumptions Pre-operational Stage
Around 7 to 11 years • Development of some logical reasoning • Limited to practical problems and specific examples Concrete Operational Stage
From about 11 years onwards • Child is capable of mature thinking • Abstract theorising • Scientific reasoning Formal Operational Stage
Birth to about 2 years - characterised by: • Movement in thinking style from action schemas to mental representations • Development of Object Permanence The Sensorimotor Stage

However, they spend significantly longer looking at this one, suggesting that they realise its impossible. That is they realise that the carrot should still be visible in the space. Baillargeon & DeVos (1991)
