1. Behaviour is learned through consequences (reward or punishment)
2. When a behaviour is rewarded (through positive or negative reinforcement) it is repeated
3. When a behaviour is punished the behaviour stops
4. Infant feels hunger, has a drive to reduce these unpleasant feelings and discomfort so is likely to cry in order to receive comfort
5. When the caregiver provides food, a feeling of pleasure is produced for the infant which is rewarding and this is called positive reinforcement
6. The behaviour which elicited the reward, i.e. crying, will be repeated
7. Reinforcement is a reciprocal process since the caregiver also experiences a reward in the form of negative reinforcement when the infant stops crying, so they too will repeat the caregiving behaviour again in the future
