Mary Ainsworth Internal Working Model

Attachment
These categories of relationship were developed by Mary Ainsworth. After weeks of spending time with these mom-baby pairs in their home environment and carefully documenting many aspects of their communication, she would then bring these one year-old infants and their mothers into a little play room with a one-way mirror for observation. The mom and the baby would be given a period of time to get used to the new space and then another person would enter the room and interact with both mom and baby in a friendly way. After a brief period with the stranger in the room, mom would then get up and leave the child with the stranger. A short while later the mom would return to the room and reunite with the infant. All the while the observers

In the home, these parents were seen to be emotionally unavailable, imperceptive, unresponsive, and rejecting. Some were responsive in many non-emotional interactions, but were very dismissive and non-responsive when the infant was emotionally needy, frustrated, or angry. These infants often expressed random aggression, and were more clingy and demanding in the home then securely attached infants.

This is a “deactivating” strategy with respect to
