In the study of children's socio-emotional development during early childhood and childhood, with reference to John Bowlby's Attachment Theory and Mary Ainsworth's 'Strange Situation' experiment, which of the following attachment patterns describes a child who experiences the most severe and inconsolable distress in the absence of the caregiver, and upon the caregiver's return, exhibits a unique conflict of simultaneously seeking proximity while displaying intense anger or resistance (ambivalent/resistant behavior)?

Understanding Attachment Patterns

According to John Bowlby and Mary Ainsworth's Attachment Theory, infants with Insecure-Ambivalent/Resistant Attachment show extreme attachment and uncertainty toward their caregiver.

• During Separation: Such children become intensely distressed and inconsolable when the caregiver leaves.
• Upon Reunion: When the caregiver returns, they display ambivalent behavior—simultaneously seeking comfort and exhibiting anger or resistance.
• Root Cause: This occurs because they lack consistent trust in the availability and responsiveness of the caregiver.
