Answer:
This demonstrates the concept of verbal appellation.
Step-by-step explanation:
Verbal appellation is the act a parent carries out when he/she uses different words when describing boys and girls doing the same behavior.
It is clear in this case; when Sydney wants to sit on her mom's lap, she calls her loving and when Damien wants the same thing she calls him a baby.
The mother is using verbal appellation, referring to Sydney as loving and to Damien as a baby.
