Bi. Fagot et Kc. Pears, CHANGES IN ATTACHMENT DURING THE 3RD YEAR - CONSEQUENCES AND PREDICTIONS, Development and psychopathology, 8(2), 1996, pp. 325-344
Crittenden has proposed a system for classifying attachment during the
preschool years. Ninety-six boys and girls were tested in the Strange
Situation at 18 months and 30 months of age. Eighteen-month-olds were
coded using the Ainsworth coding system, and the 30-month-olds were c
oded using Crittenden's preschool attachment coding system. When child
ren changed classification categories, it was not random movement but
was in accordance with Crittenden's predictions of reorganization of t
he child's capacities. Mothers and children were also observed in the
home at 18 and 30 months of age, and children were observed in playgro
ups from 18 to 30 months of age. The children were rated by their teac
hers on problem behaviors and peer relations and given achievement tes
ts at age 7 years. Parenting of the children and child behaviors at 30
months differed by attachment classification and predicted both child
ren's performance on achievement tests and teacher reports of children
's behavior at 7 years. The findings are discussed in terms of reorgan
ization of working models of attachment on the basis of changing child
competencies.
