Tina is introducing her topic by saying, "today i will be talking about the fundamental emotional bond that develops between the infant and the caregiver." what is the topic of her presentation?

I believe the answer is: Attachment

In psychology, attachment refers to the emotional bond that formed between one individual to another, which would determine their influence in each other's life. For infant, attachment tend to be formed naturally toward the primary caretakers which they automatically perceive as their main method of survival.
