Around 12-18 months, children begin to show an understanding of others' intentions, such as reaching for an object that someone else is looking at.

Self-awareness is not a component of understanding others' mental states, but rather a prerequisite for it.

The false-belief task is a common method for assessing theory of mind in children, as it requires them to understand that someone else may have a false belief about the location of an object.

Children typically develop the ability to pass the false-belief task around 4-5 years of age, indicating the emergence of theory of mind.

Language skills, social interaction, and executive function have all been found to contribute to the development of theory of mind in children.

Empathy is the ability to understand and share the emotional experiences of others.

Self-awareness is not a component of empathy, but rather a prerequisite for it.

Attachment relationships, social interaction, and temperament have all been found to contribute to the development of empathy in children.

Perspective-taking is the ability to understand and adopt the perspective of another person.
