The interface between the psychobiological and cognitive models of attachment

Attachment security in children with autism

Nineteen autistic children were examined in a modified version of Ainsworth's Strange Situation. The attachment security of 15 children could be classified. Each of these children displayed disorganized attachment patterns, but almost half (40%) of them were subclassified as securely attached. To assess the validity of the attachment classifications, children and their mothers were observed in a separate interaction. Mothers of children who were subclassified as securely attached displayed greater sensitivity than mothers of children who were subclassified as insecurely attached. Children who were subclassified as securely attached more frequently initiated social interaction with their mothers than did children who were subclassified as insecurely attached. Children with secure and insecure subclassifications were compared to investigate correlations between attachment organization and representational ability and social-emotional understanding. Although children with underlying secure attachments were no more likely to initiate joint attention, they were more responsive to bids for joint attention, made requests more frequently, and demonstrated greater receptive language ability than children subclassified as insecurely attached. Discussion focuses on dynamics that may contribute to individual differences in the attachment organization of autistic children and on the reciprocal relationship between advances in our understanding of normal and pathological development.

Early detection of core deficits in autism

The goal of this review of the research literature is to discuss approaches to the early detection of autism in infancy. Early detection would enable diagnoses to be made before 18 months of age rather than at 24-30 months, the age where diagnoses start to be made now. After summarizing the criteria for a deficit to be considered "core" to the disorder, the literature on research strategies used in early detection is examined. In order to guide the design of future studies, the review then turns to an overview of what is known about the processes of early social development in typically developing children that underlie the domains in which core deficits are manifested in young children with autism. The social domains covered in the review are those that show development in typically developing infants below 18 months of age: dyadic interaction and imitation; emotion discrimination; and attachment. The review concludes that all of these areas are worthy of investigation in young children, particularly those at higher risk of showing some of the core deficits of autism such as the infant siblings of children with autism.
