Object constancy (if I can't see it, it's not there, panic when they don't see caregiver).
Their understanding of the world is based on external actions and characteristics.
Internal mental states can only be affected by physical actions/impact.
In patients: Only know they're loved if they get reassurance through Whatsapp messages Sometimes overlaps with:
**Psychic equivalence (1,5-3 years):**
Own internal = external reality
Concrete understanding/suspension of doubt (I feel (that there's a monster under the bed), so there must be)
Rigid beliefs and thoughts "Knowing/reading" the minds of others
No room for alternative perspectives
In patients: I don't feel stuck, I am stuck. Need to join that perspective initially Flashbacks: Feeling that you are in the situation
