Aim
To determine the age at which children begin to demonstrate an awareness of their own reflection in a mirror
Meathod
Infants nose was maked red (with a sticker or lipstick) without its knowing
Infant was then placed in front of a mirror
If the child showed recognition that the mark was there (e.g. they touched the red area), then they are considered to be self-awareness
Results
Study concluded that self-recognition typically develops between 18 and 24 months of age
Strengths (think GRAVE)
Simple and replicable
Non-invasive
