To match the developmentalists with their contributions to the theory of attachment, we can identify the key figures and their theories:

1. Attachment is made between infant and the person who feeds them (oral stimulation).

   • The answer is Sigmund Freud. Freud's psychosexual theory suggested that attachment is formed through oral stimulation, as the infant's primary source of pleasure and attachment is through feeding.

2. Attachment is NOT based on oral stimulation. Using monkeys, this person showed that attachment is related to the comfort infants receive.

   • The answer is Harry Harlow. Harlow's experiments with rhesus monkeys demonstrated that attachment is more about the comfort and security provided by a caregiver rather than just feeding, as the monkeys preferred a soft, comforting surrogate mother over a wire one that provided food.

3. A sense of physical comfort and sensitive care establish attachment and set the stage for healthy attachment for the rest of a person's life.

   • The answer is John Bowlby. Bowlby proposed that a secure attachment formed through sensitive and responsive caregiving is crucial for healthy emotional and social development throughout life.

4. Both infant and parent are biologically predisposed to form attachments.

   • The answer is John Bowlby. Bowlby also emphasized that attachment is an evolutionary mechanism, with both infants and parents biologically programmed to form attachments to ensure the infant's survival.

5. Used the "strange situation" experiment to formulate attachment styles secure, avoidant, resistant, and disorganized.

   • The answer is Mary Ainsworth. Ainsworth developed the "Strange Situation" procedure to observe attachment relationships between a caregiver and child, leading to the identification of different attachment styles: secure, avoidant, resistant, and later, disorganized.

These contributions highlight the evolution of attachment theory from early psychoanalytic ideas to more comprehensive understandings of the emotional bonds between infants and caregivers.
