Internal working model of attachment
Internal working model of attachment is a psychological approach that attempts to describe the development of mental representations, specifically the worthiness of the self and expectations of others' reactions to the self. This model is a result of interactions with primary caregivers which become internalized, and is therefore an automatic process. John Bowlby implemented this model in his attachment theory in order to explain how infants act in accordance with these mental representations. It is an important aspect of general attachment theory.
Developmental psychology
Attachment style can affect the relationships between people. Attachment is established in early childhood and attachment continues into adulthood. An example of secure attachment continuing in adulthood would be when the person feels confident and is able to meet their own needs. An example of anxious attachment during adulthood is when the adult chooses a partner with anxious-avoidant attachment.
