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.
Dependency need
Dependency needs can sometimes be associated with Attachment Theory. Attachment can be defined as a "deep and enduring emotional bond that connects one person to another across time and space." (Ainsworth, 1973; Bowlby, 1969) Attachment is thought to first occur between an infant and his or her primary caregiver. (Hetherington & Parke, 1999) Harry Harlow and his research in developmental psychology showed that attachment between infant and caregiver is vitally important to the psychological development of the infant and requires physical contact with a warm and responsive mother. (Larsen & Buss, 2008) These early experiences and reactions of the infants to the primary caregivers become working models for later adult relationships. (Larsen & Buss, 2008) Therefore, conclusions can be visibly drawn linking attachment and dependency need; vital, infantile needs for mothering, love, affection, shelter, protection, security, food, and warmth (dependency need) can stem from the type of interaction between that of an infant and his or her primary caregiver. Three different types of attachment styles, securely attached, avoidantly attached, and ambivalent attached, can result from varying levels and styles of care a primary caregiver provides an infant.
