Bowby's theory is an evolutionary theory because he believes that attachment is a behavioral system that evolved because of its survival and reproductive value. Caregiving is adaptive because species have adapted over many years to improve the survival of offspring so they can later reproduce. Bowlby's theory is made up of many different ideas. According to Bowlby, children have an innate drive to become attached to those who care for them. This is similar to that of imprinting which is an innate willingness to develop a strong bond with the maternal figure that occurs during the sensitive period. Because attachment is innate, there is likely to be a limited window for development. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get Original Essay It is said to occur when a baby is 3-6 months old when he or she is most sensitive to an attachment. After this stage attachment may become more difficult. The internal working model is a set of concepts about relationships and what to expect from others. In the short term, it provides the child with insight into caregiver behavior. In the long term it serves as a model for future relationships as it generates expectations. This is similar to the continuity hypothesis and the idea that emotionally secure children go on to become emotionally secure, confident, and confident adults. Social releases elicit care such as smiling, crying, looking cute, etc. This induces monotropy, a relationship that the child has with his primary attachment figure is of particular significance. Newborns also have secondary attachment figures that form a hierarchy. These secondary attachment figures serve as a safety net and also contribute to social development. Attachment also promotes independence rather than independence. A secure base helps this by giving the child a place to come home to after exploring the world. Schaffer and Emmerson showed support for Bowlby's Evolutionary Attachment Theory by observing 60 children. They found that the children had many attachments (grandparents, mothers, fathers, friends, etc.) However, they maintained one primary attachment figure. This was based on the quality of caregiving that shows support for monotropy, the idea that we have one attachment figure and a hierarchy of secondary attachments. Harlow also supported Bowlby's theory by demonstrating that baby monkeys who formed an attachment with a callous and unresponsive metallic mother became rather maladjusted adults who had problems with reproduction, i.e. interaction is important. This therefore shows that having a primary attachment figure is innate and is important for emotional and social development. However, the multiple attachment model suggests that there are no primary or secondary attachments. All accessories are integrated into a single model. This shows a weakness in Bowlby's attachment theory because it states that a primary attachment figure has special significance in emotional development. It is also stated that secondary attachment figures that form a hierarchy also contribute to social development. The multiple attachment model removes this problem.

This states that personalities can influence attachment. Belsky and Ravine assessed infants' ages from 1 to 3 days and found that calmer, less anxious infants were more likely to have a secure attachment. This contradicts the theory.
