A researcher places a red dot on the forehead of a 12 month old, then places her in front of a mirror. She reaches out and touches the red dot on the mirror. At 18 months of age, the researcher repeats the experiment. At that point the child looks in the mirror, then reaches up and touches her own forehead. She has developed:

Self-awareness

Explanation: self awareness simply refers to having knowledge of one's own personality. It could be described as having a conscious understanding of one's personality, emotion, feelings or other related individual attribute or character.

The scenario above indicates the development of reflective Self-awareness which is developed in a baby at around 18 months. It monitors how a child react when they see a reflection of themselves in mirrors, images or other reflective surfaces.

At 12 months, the baby hasn't developed reflective Self-awareness and only view their reflection as seeing other children.

However, at 18 months, reflective Self-awareness has been developed and they recognize themselves when reflection occurs. Hence, the reason why she reaches out and touches her forehead to locate the red dot placed on her forehead.
