The dominant advice to parents in the 1950s, based on behavioral theory, was to avoid “spoiling” infants by picking them up or otherwise comforting them when they cried. In a series of studies in the 1960s and early 1970s, Ainsworth showed that the effect of early nurturance was exactly the opposite of what the behaviorists expected. Babies whose parents responded readily and fully to their cries in the first months of life were, at one year, more independent and intrepid than babies whose parents had ignored their cries. In preschool, the pattern continued—the children whose parents had responded most sensitively to their emotional needs as infants were the most self-reliant. Warm, sensitive parental care, Ainsworth and Bowlby contended, created a “secure base” from which a child could explore the world. Although psychologists in the 1960s had at their disposal many tests to evaluate the cognitive abilities of infants and children, they had no reliable way to measure a child’s emotional capacities. So Ainsworth invented a method to do just that, an unusual procedure called the Strange Situation. At Johns Hopkins University, in Baltimore, where Ainsworth was a professor, a mother would bring her twelve-month-old child into a lab set up as a playroom. After playing with her infant for a while, the mother left the room, sometimes leaving the child with a stranger, sometimes leaving him or her alone. After a brief interval, she would return. Ainsworth and her researchers observed the whole procedure through one-way mirrors, and then categorized the children’s reactions. Most children greeted the returning mother happily, running to her and reconnecting with her, sometimes tearfully, sometimes with joy. These children Ainsworth labeled securely attached, and in subsequent experiments over the past few decades, psychologists have come to believe that they make up about 60 percent of American children. Children who did not have a warm reunion—pretending to ignore the mother when she returned; lashing out at her; falling to the floor in a heap—were labeled anxiously attached. Ainsworth found that a child’s reaction in the Strange Situation was directly related to his parents’ degree of responsiveness in that first year of life. Parents who were attuned to their child’s mood and responsive to his cues produced securely attached children; parenting that was detached or conflicted or hostile produced anxiously attached children. And early attachment, Ainsworth said, created psychological effects that could last a lifetime.
Against common intuition, readily responding to your babies cries at the infant stage will actually lead to them being more independent at the 1 year mark. We sometimes think that “forcing” situations where people get to sink or swim will make them stronger. However, such situations might not necessarily apply to kids. Of course, putting them in a bubble, like in Haidts book, “Codding of the American Mind”, is also not ideal. The key is balance. We need to be stressed occasionally to grow, but not too often and long, otherwise we might break.
