Learning Theory: Classical and Operant Conditioning
Learning theory, developed by Dollard and Miller (1950), is nicknamed "cupboard love" theory because it argues babies simply attach to whoever feeds them. It's a straightforward explanation that treats attachment like any other learned behaviour.
Classical conditioning works like this: initially, the caregiver means nothing special to the baby (neutral stimulus). Food naturally makes babies happy (unconditioned stimulus creating an unconditioned response). When the same person repeatedly provides food, the baby starts expecting food whenever they see that person (caregiver becomes conditioned stimulus). Eventually, just seeing the caregiver makes the baby happy - that's attachment forming through a conditioned response.
Operant conditioning creates a cycle where crying gets results. Baby cries for food, caregiver responds, baby stops crying when fed (negative reinforcement), and future needs get directed to that same caregiver. It's actually a two-way process since the caregiver also feels relief when the crying stops.
Key insight: According to this theory, attachment is a secondary drive - we naturally want to reduce hunger (primary drive), so we learn to attach to whoever satisfies that need.
