Questions: Ainsworth followed Harlow's research and identified stranger anxiety critical period secure/insecure attachment imprinting

Ainsworth's research, particularly her work on attachment theory, was influenced by Harlow's studies on rhesus monkeys. However, Ainsworth is most notably associated with the concept of secure and insecure attachment, which she identified through her "Strange Situation" study. This study involved observing children's reactions to being left alone and then reunited with their caregiver, which helped categorize their attachment styles as secure, insecure-avoidant, or insecure-resistant.

• Stranger Anxiety: This is a concept related to attachment theory, but it is more directly observed in the context of the Strange Situation as a behavior exhibited by infants when exposed to strangers.

• Critical Period: This term is more closely associated with ethologist Konrad Lorenz and his work on imprinting in animals, although it is relevant in the context of human development as well.

• Secure/Insecure Attachment: Ainsworth's primary contribution to attachment theory, identifying different attachment styles based on children's behavior in the Strange Situation.

• Imprinting: This concept is primarily associated with Lorenz and refers to the rapid learning process that occurs in some animals, leading them to follow and form an attachment to the first moving object they see, usually their mother.

In summary, Ainsworth is best known for her work on secure and insecure attachment.
