摘要:Mother-Child Interactions during Problem Solving were analyzed in relation to the child`s attachment security and temperament. Subjects were fifty-three 44-to 57-month-old children and their mothers. Attachment security was assessed by Attachment Q set (Waters,1987);mother-child interactions were observed at home,and maternal ratings of child temperament were collected by questionnaire (Chun 1993). Attachment security scores were positively related to mother`s cognitive assistance and positively interactions with the child and to the child`s positive affect toward mother. The child`s activity perceived by mother was negatively related to mother`s efficient interactions and positively to the child`s "reliance on mother." The child`s behavior toward the mother in the task session and the child`s temperament added variance above attachment in accounting for the mother`s behavior.
