Human developmental periods
Attachment theory is a theoretical system developed by British physician and psychoanalyst John Bowlby, focusing on the developmental importance of close, intimate, emotionally meaningful relationships. Attachment in this theoretical current has been described as a system of biological impulses necessary to ensure survival in the first years of his life. This trend deals with the effects of the negative impact on development of the loss of significant objects, i.e. biological caregivers as a result of depreciation of attention and involvement.In 1965, Mary Ainsworth created the Strange Situation Procedure as a way of assessing individual differences in attachment behavior through individual stress responses and safe shelter concepts.The theory of attachment is used in therapeutic practice, especially in the field of civil partnerships and in the ethological model of developmental psychology. An early attachment style can affect relationships with people. The attachment style model is established in early childhood and is a relational style in adulthood.
