Step-by-step explanation:
This behavior can be considered a function of communication known as emotional expression. When a toddler screams at the sight of a theater mask, they are expressing their fear or discomfort through their vocalization and body language.
In this case, the toddler's response is a natural emotional reaction to something unfamiliar and potentially frightening. The mask may seem strange and threatening to the child, causing them to scream as a way of communicating their distress.
It's important to remember that toddlers are still developing their communication skills, and they often rely heavily on nonverbal cues to express their emotions and needs.
