Ainsworth observed 1-year-olds in the Strange Situation and at home and found three main patterns of attachment. In addition, other researchers found a 4th pattern. Which is the 4th pattern (NOT one of the 3 identified by Ainsworth)?
Secure attachment: infant is quickly and effectively able to obtain comfort from an attachment figure in the face of distress
Avoidant attachment: infant rarely cries when separated from the primary caregiver and avoids contact on his or her return
Ambivalent (resistant) attachment: infant becomes anxious before the caregiver leaves, upset during his or her absence, and both seeks and resists contact on his or her return
Disorganized-disoriented attachment: after separation from the primary caregiver, the infant shows contradictory, repetitious, or misdirected behaviors on the caregiver’s return
