I believe the right answer is theory of mind.
The "theory of mind" refers to our understanding of people as mental beings, each with their own mental states, such as thoughts, desires, motives and feelings. We use the theory of the mind to explain our own behavior to others, telling them what we think and want, and interpret the conversation and behavior of other people when considering their thoughts and desires. This is the most important development in early childhood, during the first five years of life.
