Perspective taking is our ability to understand a situation from another person's viewpoint.
To investigate perspective taking's development, Selman asked children aged 4-6 how they felt in scenarios involving dilemmas.
One scenario involved a child called Holly (who promised her father not to climb trees), preparing to climb a tree to save a kitten. Based on the child's response, they were categorised into a specific stage of perspective taking.
The perspective taking stage that children were allocated to was found to correlate with their age.
