Step-by-step explanation:
Experts believe that a particular attachment style is acquired through a combination of genetics and early life experiences. According to attachment theory developed by John Bowlby and furthered by Mary Ainsworth, infants form a primary attachment to their caregiver, usually the mother, which plays a crucial role in their emotional and social development. This attachment is influenced by factors such as the caregiver's responsiveness, sensitivity, and consistency in meeting the child's needs. Additionally, a child's temperament and the cultural context can also influence the development of attachment style.
