Abstract
Although Ainsworth and Bowlby’s perspective on attachment relationships has instinctive underpinnings, they also recognized variability in the ways caregiving is implemented in different ecologies. Ainsworth’s naturalistic observations in two different societies provided early evidence about the development of infant–mother attachment, differences in the quality of attachment relationships, and the role of maternal care in attachment development. Further, her research demonstrated the importance of an ethological approach for research within and across cultures. Employing similar concepts and methods, my collaborators and I have tested and expanded Bowlby’s and Ainsworth’s ideas about the generality of the sensitivity construct and sensitivity-security link. In our research, ethological observations have been key to elaborating the quality of care construct and studying child–mother attachment relationships in different cultures, social contexts, and ages.
