The argument in the text book that secure attachments promotes positive relationship later on in life is reasonable and understandable. There is a logical correlation in these two factors. A child that is securely attached to his mother will develop a personality that will contribute to a fulfilling relationship. However, there are other factors to consider apart from the parenting a child received in his or her early years. The environmental can play a mojor role in this. For example if a person experience bad relationship over and over, of if he or she is surrounded by friends who always complain about bad relasionship they are having, this might influence that person in his or her decision to start a relationship.
I agree. While the relationship between a child and their parent is important, that is not the only important relationship a child is exposed to. Relationships with friends and other adults, such as other family members, can also have lasting effects that probably attribute to a way a child develops.
I agree that environmental factors make it difficult to construct an accurate model of behavioral development. Another factor that could effect the outcome of a child's social development is exposure to other children. For example, consider a child that develops a secure, healthy attachment to his caregiver. If the child is never exposed to any other children his age, he will never have the opportunity to use this relationship as a template, and the scope of his social skills would be limited to interaction with his caregiver. Thus, a positive behavioral outcome seems to be not only dependent on a positive template, but on experience in using the template to interact with peers.
