Operant conditioning of attachment
1. If a behaviour results in agreeable consequences, it is likely to be repeated
2. If a behaviour results in disagreeable consequences, it is likely to decline
3. Crying results in feeding, so crying is reinforced
4. Escaping from an unpleasant stimulus is agreeable, so it is a reinforcer
5. Carer dislikes hearing a baby cry, so cessation of crying is a negative reinforcer
6. Smiling by the child is rewarding, so it is a positive reinforcer
