Answer:
secure attachment
Step-by-step explanation:
Bowlby was a psychologist who was known for his Attachment theory.
According to this theory, the term attachment refers to an emotional bond that people develop and that connect them to each other. According to him, the first bond that we create in our lives is the one towards our caregiver and the attachment we create will depend on how our caregiver responds to our needs.
When our caregiver is warm and responsive the infant's develop a secure attachment which make the infant feel secure and confident in his future relationships and accepts the separation from the mother without experiencing it as a threat.
Therefore, Bowlby hypothesized that when a caregiver is warm and responsive to an infant's needs, an emotional bond is formed, known as "secure attachment"
