"Level 1: Should I Eat the Cookie? Preconventional Reasoning Stage 1. It depends. How likely am I to get punished? Being punished is unpleasant. Aggression typically peaks around ages two through four, after which kids are reined in by adults' punishment ("Go sit in the corner") and peers (i.e., being ostracized). Stage 2. It depends. If I refrain, will I get rewarded? Being rewarded is nice. Both stages are ego-oriented--obedience and self-interest (what's in it for me?). Kohlberg found that children are typically at this level up to around ages eight through ten."
