John Bowlby suggested that infants are born with the innate tendency to form an attachment. The attachment is a reciprocal relationship between the infant and its primary caregiver. This suggests that adults have an innate ability to form an attachment with their infant. This idea is supported by a study carried out by Lorenz. The results of this study suggest that animals ‘imprint’ on the first moving object they see. The imprint is an attachment. Since humans are also animals, it is believed that they also form attachments. Bowlby also suggested that there is a critical period of 2 and half years in which an attachment must be formed. Failure to form an attachment in that time may result in difficulties in forming proper relationships in the future. However other psychologists argue that this may be a sensitive period rather than a critical one. In essence, it is easiest to form an attachment during the first 2 and a half years of a child’s life, but attachments may be formed after that time. Bowlby proposed the idea that a child will form only one attachment. He called this idea monotropy. He stated that the infant has only one primary caregiver to whom the child will form an attachment. However this idea has been contradicted by other psychologists who say that a child can form attachments to more than one person, for example to their mother as well as their father. A key feature of Bowlby’s theory is that the attachment formed as a child provides the child with an internal working model of relationships, which will in turn guide relationship behaviour in the future. A secure child will develop a positive internal working model of itself because of the sensitive emotional care it has received from its primary caregiver. An insecure-avoidant child will develop a negative internal working model in which it sees itself as unworthy because its primary
