“We believe that the caregiver’s capacity to observe the moment-to-moment changes in the child’s mental state is critical in the development of mentalizing capacity. The caregiver’s perception of the child as an intentional being lies at the root of sensitive caregiving, which attachment theorists view as the cornerstone of secure attachment (Ainsworth et al. 1978; Bates, Maslin, and Frankel 1985; Belsky and Isabella 1988; Egeland and Farber 1984; Grossmann, Grossmann, Spangler, Suess, and Unzner 1985; Isabella 1993; Isabella and Belsky 1991). Secure attachment, in its turn, provides the psychosocial basis for acquiring an understanding of mind. The secure infant feels safe in making attributions of mental states to account for the behavior of the caregiver. In contrast the avoidant child shuns to some degree the mental state of the other, while the resistant child focuses on its own state of distress, to the exclusion of close intersubjective exchanges. Disorganized infants may represent a special category: hypervigilant of the caregiver’s behavior, they use all cues available for prediction; they may be acutely sensitized to intentional states and thus may be more ready to construct a mentalized account of the caregiver’s behavior. We would argue (see below) that in such children mentalization may be evident, but it does not have the central role in self-organization that characterizes securely attached children. We believe that what is most important for the development of mentalizing self-organization is the exploration of the mental state of the sensitive caregiver, which enables the child to find in the caregiver’s mind (that is, in the hypothetical representation of her mind that he constructs to explain her behavior toward him) an image of himself as motivated by beliefs, feelings, and intentions. In contrast, what the disorganized child is scanning for so intently is not the representation of his own mental states in the mind of the other, but the mental states of that other that threaten to undermine his own self.”
