Evidence Against Learning Theory
Here's where things get interesting - Schaffer and Emerson's research completely challenges the "food equals love" assumption. Their 1964 study found that 39% of babies formed their strongest attachment with someone who wasn't their main feeder or carer.
Instead, babies were drawn to secondary caregivers who were simply more responsive, playful, and emotionally available. Think about it - maybe the parent who works long hours but plays peek-a-boo becomes the favourite, not the one doing all the nappy changes.
Harlow's monkey experiments deliver an even stronger blow to learning theory. When baby monkeys could choose between a wire "mother" that provided food and a soft cloth "mother" that offered comfort, they overwhelmingly preferred the cuddly option. They'd dash over for quick feeds but spend most of their time clinging to the comfort-giving figure.
Bottom Line: If attachment was just about food and meeting physical needs, these research findings simply wouldn't make sense.
