Preoperational Stage (2–7 years)
From about 2 to 7 years the child can use symbols — words, images, pretend play — but cannot yet perform logical mental 'operations'. CTET loves the limitations of this stage. Egocentrism is the inability to see a situation from another person's point of view (the child assumes everyone sees, knows and feels what they do). Centration is focusing on one feature of a situation and ignoring others. Because of centration the child fails conservation — the understanding that quantity stays the same despite a change in appearance: poured into a tall thin glass, the 'taller' water now looks like 'more'. The child's thinking is also irreversible (cannot mentally reverse the pouring) and shows animism (treating objects as alive — 'the naughty chair hurt me'). Pretend/symbolic play flourishes here.

Key Concepts — Quick Reference
The four stages (memorise the ages cold)
| Sensorimotor | 0–2 yrs · senses & action · object permanence |
|---|---|
| Preoperational | 2–7 yrs · symbols & language · egocentrism, no conservation |
| Concrete Operational | 7–11 yrs · logic on concrete things · conservation, reversibility |
| Formal Operational | 11+ yrs · abstract & hypothetical reasoning |
How thinking changes
| Schema | A mental framework for organising knowledge |
|---|---|
| Assimilation | Fit new information INTO an existing schema |
| Accommodation | CHANGE the schema to fit new information |
| Equilibration | The drive to balance assimilation & accommodation |
