Which researcher studied attachment phases in children from institutions and foster homes?

The researcher who studied attachment phases in children from institutions and foster homes is John Bowlby. He is widely recognized for his pioneering work in attachment theory, which emphasizes the importance of the relationships formed between children and their caregivers. Bowlby conducted extensive observations and analyses, primarily focusing on children who experienced a lack of stable, nurturing relationships, such as those in institutions or foster care settings.

His research highlighted how early interactions with caregivers shape a child's emotional and social development, laying the groundwork for attachment styles that influence behavior and relationships later in life. Bowlby's concepts, such as secure and insecure attachment, are fundamental to understanding children's emotional health and development in various contexts, particularly in situations of separation or loss. This focus on the impact of early relationships and the resultant attachment styles underscores the significance of Bowlby's contributions to psychology and child development.
