Test for Lewis (1990) Red Nose Test - Brooks-Gunn (1979)

Aim

To determine the age at which children begin to demonstrate an awareness of their own reflection in a mirror

Meathod

1. Infants nose was maked red (with a sticker or lipstick) without its knowing

2. Infant was then placed in front of a mirror

3. 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
