Hazan and Shaver noted that the relationship between infants and caregivers and the relationship between adult romantic partners share the following features:
- both feel safe when the other is nearby and responsive
- both engage in close, intimate, bodily contact
- both feel insecure when the other is inaccessible
- both share discoveries with one another
- both play with one another's facial features and exhibit a mutual fascination and preoccupation with one another
- both engage in "baby talk"
1. First, if adult romantic relationships are attachment relationships, then we should observe the same kinds of individual differences in adult relationships that Ainsworth observed in infant-caregiver relationships. We may expect some adults, for example, to be secure in their relationships--to feel confident that their partners will be there for them when needed, and open to depending on others and having others depend on them. We should expect other adults, in contrast, to be insecure in their relationships. For example, some insecure adults may be anxious-resistant: they worry that others may not love them completely, and be easily frustrated or angered when their attachment needs go unmet. Others may be avoidant: they may appear not to care too much about close relationships, and may prefer not to be too dependent upon other people or to have others be too dependent upon them.
