Twenty topics are addressed through an examination of relevant theory, research findings, and clinical evidence: (1) a "who's who" list of researchers on attachment; (2) definition of attachment; (3) behaviors indicating attachment system activation; (4) the dynamic interplay of the attachment system with other systems, such as exploration/curiosity; (5) measurement of attachment in infancy; (6) attachment relationships revealed by the "Strange Situation"; (7) attachment is relationship-specific; (8) cross-cultural attachment findings; (9) stability of attachment classifications over time; (10) impact of child abuse on attachment; (11) relation of infant attachment to later child competence and mastery; (12) effect of early mother return to employment on attachment; (13) measurement of attachment in preschoolers, adolescents, and adults; (14) relationship of preschoolers' interactions with peers and teachers to early attachment to parents; (15) impact of the parent-teacher relationship on infant attachment to the teacher; (16) boy and girl differences in attachment; (17) intergenerational consequences of attachment; (18) relation of attachment and temperament; (19) predictive value of attachments to mother and father for later socioemotional functioning; and (20) how child care providers can promote secure attachment, offering numerous specific suggestions for child caregivers.
